Polyethyleneimine: An Important Building Block in Various Applications In Industry

What is Polyethyleneimine?

Polyethyleneimine (PEI) is a polymeric compound composed of repeating units of ethyleneimine monomers. It is a white solid polymer that is soluble in water. PEI is classified as a branched or linear cationic polymer that is formulated through the polymerization of aziridine. The polymer's molecular weight can range from 300 to over 10,000 Daltons depending on its intended use. Properties and Structure of PEI

PEI is a polymer that contains secondary nitrogen atoms along its backbone that provide cationic charge centers. These nitrogen atoms can interact and form electrostatic bonds with negatively charged macromolecules or surfaces. The cationic nature of PEI allows it to act as a polycation and complex or condense with negatively charged substances like DNA or RNA. PEI is also very hygroscopic due to its numerous amine groups that attract water molecules. Its branched structure provides greater buffering capacity and DNA condensation ability compared to the linear form of PEI. Uses in Gene Delivery

One of the most important uses of Polyethyleneimine is in non-viral gene delivery applications. Its cationic charge allows it to efficiently bind and compact negatively charged nucleic acids like plasmids, forming nano-sized polyplexes that can transfect cells. The polyplexes are effectively endocytosed by cells and the low pH of endosomes triggers PEI to buffer the compartment, releasing the DNA from the complex. This "proton sponge" mechanism of PEI facilitates effective intracellular delivery and expression of the gene of interest. It is commonly used as a transfection agent for in vitro studies as well as in vivo gene therapies and vaccines. Role in Biomaterials and Tissue Engineering

Given its favorable properties, PEI also finds extensive use as biomaterials for tissue engineering applications. Its cationic nature permits binding of PEI to negatively charged components of the extracellular matrix like glycosaminoglycans. This helps direct cell adhesion, growth, and function. PEI can act as a coating onto implants and scaffolds, promoting their integration with surrounding tissues. It allows bioconjugation of signaling cues to influence cell behavior in regenerative therapies as well. The tunable properties of PEI through controlling its molecular weight or branching also expand its utility in the design of biomaterials.

In addition to the major uses mentioned above, PEI has applications in many other fields due to its versatile characteristics. It acts as a flocculating agent in wastewater treatment processes to remove pollutants and purify water. PEI finds increasing importance as a hardener in epoxy resins used in manufacturing infrastructure and electronics. Its buffering ability makes it valuable as a non-corrosive alternative to replace hazardous chemicals in industrial cleaning agents as well. Overall, the unique polymeric structure and properties of PEI designate it as an essential building block material with myriad applications.

Some Spider Silk Facts

The strongest spider silk is produced by Darwin’s Bark Spider, which is twice as strong as any gossamer recorded before. It has a tensile strength of up to 520 megajoules per cubic metre.

Gossamer is stronger than steel and kevlar, and it has been suggested that a single pencil-width strand of the stuff could stop a Boeing 747 in its tracks.

The reason we can break such a strong material is because it is 20 times thinner than a human hair, usually measuring just 0.003mm across.

There are seven types of silk produced by a spider of Araneus Diadematus: dragline/major ampullate silk (which forms the basic structure of a web and also the web the spider itself dangles from), minor ampullate silk (which forms the auxiliary spiral in the centre of a web), flagelliform silk (which forms the core fibres of the ‘capture spiral’) , aggregate silk (forming the aqueous coating on a web), cylindriform silk (tough outer silk of an egg sac), aciniform silk (soft inner silk of an egg sac also used for swathing prey) and pyriform silk (which is used as a sort of cement for joining and attaching different parts of the web).

These little architects have seven different silk glands, as a result, all of which are employed by the spinnerets at the spider’s rear end.

Gossamer is made up of a blend of different proteins linked together in a chain: it consists of proteins rich in nonpolar (example; fats, oils, gasoline and petrol) and hydrophobic (example; oils, waxes and steroids) amino acids like glycine (C₂H₅NO₂ - white solid) and alanine (C3H7NO2 - white powder) but no (or very little) tryptophan (C11H12N2O2).

Glycine is a compound our bodies use to make protein. It is an antioxidant, anti-inflammatory, cryoprotective and immunomodulatory in peripheral and nervous tissues.

Alanine is an alpha amino acid also used to make proteins. It is a hydrocarbon. Hydrocarbons are divided into two classes in biochemistry: aromatic compounds and aliphatic compounds (from the Greek word ‘aleiphar’ - fat/oil). Alanine falls into the latter category. Another example of an aliphatic compound is squalene, which is found in shark livers and the stomach oil of birds.

So spidersilk seems to be mainly made up of carbon, hydrogen, nitrogen and oxygen, with more hydrogen and carbon than any other element, making it an aliphatic hydrocarbon based substance. (I think. I’m not a scientist, I’m just making an educated guess.)

So why have we not spun our own clothes / harvested spidersilk? Multiple reasons.

The main reason being that spiders can’t be farmed like silkworms due to the fact that they will cannibalise each other in close proximity. The silk is so fine that it would take harvesting from 400+ spiders to make a single yard of silk. And the silk also hardens when exposed to air which makes it difficult to work with.

This silk hardens as it passes through the spider’s spinnerets. Also, the problem with trying to genetically engineer spidersilk ourselves is that we can only partially replicate its chemical makeup.

Also here’s the heckin chungus of a spider in question, with the world’s strongest web:

He’s buff and he knows it. Proud chonky fella. He’s cute. 😭🥺

New zirconia-based catalyst can make plastics upcycling more sustainable

A new type of catalyst breaks down polyolefin plastics into new, useful products. This project is part of a new strategy to reduce the amount of plastic waste and its impact on our environment, as well as recover value that is lost when plastics are thrown away. The catalyst was developed by a team from the Institute for Cooperative Upcycling of Plastic (iCOUP), a U.S. Department of Energy, Energy Frontier Research Center. The effort was led by Aaron Sadow, the director of iCOUP, scientist at Ames National Laboratory, and professor at Iowa State University; Andreas Heyden, professor at the University of South Carolina; and Wenyu Huang, scientist at Ames Lab and professor at Iowa State. The new catalyst is made only of earth-abundant materials, which they demonstrated can break carbon-carbon (CC) bonds in aliphatic hydrocarbons.

Aliphatic hydrocarbons are organic compounds made up of only hydrogen and carbon. Polyolefin plastics are aliphatic hydrocarbon materials composed of long chains of carbon atoms linked together to form strong materials. These materials are a big part of the plastic waste crisis. Wenyu Huang said, "More than half of produced plastics so far are polyolefin based."

Dwarf planet Ceres: Building blocks of life delivered from space

The dwarf planet is a bizarre, cryovolcanic world. However, the organic deposits discovered on its surface so far are unlikely to originate from its interior.

Organic molecules are among the necessary inventory of life-friendly worlds. On Earth, the compounds of carbon, hydrogen and – in smaller quantities – other elements form the basic building blocks of all life. In recent years, researchers have found such molecules at great distances from the Sun: on trans-Neptunian objects, comets, and far-away asteroids. These bodies are thought to be largely unaltered remnants from the early days of the Solar System. The building blocks of life may therefore have been part of their “basic configuration” from the very beginning and possibly reached the inner Solar System only later.

For the current study, the researchers looked for previously unknown deposits of organic material on dwarf planet Ceres. With its location in the middle of the asteroid belt between the orbits of Mars and Jupiter, the body is neither clearly native to the inner nor the outer Solar System. According to earlier studies, this location could even be its birthplace. Scientists are therefore interested in the origin of Ceres’s organic components. Did they originate locally in the asteroid belt? Or did they arrive later?

Searching for Organics from afar

Evidence of deposits of organic material was already found during the early stages of the Dawn mission. The Dawn spacecraft reached Ceres in March 2015 and accompanied it for about three and a half years. During this time, the scientific camera system and the spectrometer on board scanned the entire surface of the dwarf planet. Potential patches of organic material can be detected from the camera data: the brightness of the light reflected from these areas increases noticeably with increasing wavelength. The spectrometer splits the light into many more wavelengths than the camera and can therefore prove or disprove the presence of organics. Unfortunately, remote data is not sufficient to identify individual types of molecules beyond doubt. However, it is certain that the discovered deposits consist of organic compounds that have a chain-like structure. Researchers refer to such molecules as aliphatic hydrocarbons.

The authors of the current study have now used artificial intelligence to comb the entire surface of the dwarf planet for traces of aliphatic organic molecules. “Sites of such organic molecules are actually rare on Ceres, and devoid of any cryovolcanic signatures” says first author Ranjan Sarkar from the MPS, summarizing the results. The vast majority of deposits can be found along the edge or near the large Ernutet crater in the northern hemisphere of the dwarf planet. Only three are located at a greater distance from it. Two patches were not previously known. A closer look at the geological structures at the locations of the organic material allows further conclusions. “At none of the deposits do we find evidence of current or past volcanic or tectonic activity: no trenches, canyons, volcanic domes or vents. Furthermore, there are no deep impact craters nearby,” says Martin Hoffmann from MPS.

Impacts from distant neighbors

During the Dawn mission, Ceres had turned out to be an extraordinary, cryovolcanic world. Under its surface, a watery brine is hidden, which in some places has been seeping to the surface until recently. “Of course, the first assumption is that Ceres' unique cryovolcanism has transported the organic material from the interior of the body to the surface,” says Andreas Nathues from MPS, head of the camera team. “But our results show otherwise,” he adds. At the sites of cryovolcanic activity, there is no proof of organic matter. And where organic compounds have been reliably detected, there is no evidence of deep or surface activity.

The researchers therefore argue that the impact of one or more asteroids from the outer asteroid belt introduced the organic material. Computer simulations show that these bodies are among the ones that most frequently collided with Ceres. Since the not-too-distant neighbors do not pick up much speed, only little heat is generated upon impact. Organic compounds can survive these temperatures.

“Unfortunately, Dawn can't detect all types of organic compounds,” Andreas Nathues points out. It is quite likely that building blocks of life were also formed in Ceres' underground ocean and perhaps even reached the surface – or are still doing so. “However, the organic deposits that have been reliably detected with Dawn so far likely do not originate Ceres itself,” he explains. Nathues continues by saying that a future lander mission would be needed to detect organic material from the interior of Ceres.

About the mission

NASA’s Dawn mission studied two bodies in the asteroid belt up close: the protoplanet Vesta from 2011 to 2012, and the dwarf planet Ceres from 2015 to 2018. The mission’s scientific camera system, the Dawn Framing Cameras, were developed, built, and operated during the mission under the leadership of MPS. The VIR spectrometer was provided by the Italian Space Agency ASI.

Aliphatic Compounds Versus Aromatic

Aliphatic compounds are a class of organic molecules characterized by their non-aromatic structure[1]. These compounds are composed of carbon and hydrogen atoms connected by single, double, or triple bonds to form open chains or non-aromatic rings[1][2]. Key characteristics: Structure: Can be saturated (alkanes) or unsaturated (alkenes and alkynes)[1] Bonding: Single, double, or triple bonds…

"Ruthenium-Catalyzed Selective Hydrogenation of Epoxides to Secondary Alcohols Thiyagarajan, Subramanian,Gunanathan, Chidambaram supporting information, p. 9774 - 9778 (2019/12/02) A ruthenium(II)-catalyzed highly selective Markovnikov hydrogenation of terminal epoxides to secondary alcohols is reported. Diverse substitutions on the aryl ring of styrene oxides are tolerated. Benzylic, glycidyl, and aliphatic epoxides as well as diepoxides also underwent facile hydrogenation to provide secondary alcohols with exclusive selectivity. Metal-ligand cooperation-mediated ruthenium trans-dihydride formation and its reaction involving oxygen and the less substituted terminal carbon of the epoxide is envisaged for the origin of the observed selectivity." https://www.lookchem.com/CASDataBase_42900-54-9.htm

What is the Difference Between PC and PVC in Thermoforming?

Thermoforming is a versatile manufacturing process allowing manufacturers to mold thin and heavy gauge materials.The main principle is to heat and soften the flat hard plastic sheet, then use vacuum adsorption on the surface of the mold, and then form it after cooling. It is widely used in plastic packaging, lighting, advertising, decoration and other industries. Generally divided into heavy gauge thermoforming and thin gauge thermoforming.

Thermoformed products are processed with thermoplastic materials. The product production principle is to heat and soften the flat plastic hard sheet material, then adsorb it to the surface of the mold with vacuum, and then cool it into shape.

Thermoformed products are widely used in the electronics, electrical appliances, and food industries. , hardware tools, cosmetics industry, toy industry, daily necessities industry, medicine, health care products, automobiles, stationery, cultural and sports supplies and other categories of industries.

Plastic thermoforming materials usually use thermoplastic plastics, and common ones include polystyrene (PS), polypropylene (PP), polyethylene (PE), polycarbonate (PC), polyvinyl chloride (PVC), thermoformed acrylic(PMMA), polyethylene terephthalate(PET), polyethylene terephthalate glycol(PET-G), high molecular weight polyethylene etc. Different plastic materials have different properties and application areas.

This article will delve into the complexity and artistry of vacuum forming, pressure forming, focusing on a comparison of two common thermoplastic sheets, PC (polycarbonate) and PVC (polyvinyl chloride).

The Difference between PC and PVC Material

Raw Material

The components of PVC material are mostly polyvinyl chloride, which is a general-purpose plastic.

The components of PC material are mostly carbonate-based, which are engineering plastics.

Property

PC material has the advantages of high strength, good transparency, and good impact resistance; relatively speaking.

PVC material is softer, has average transparency, and has inferior mechanical properties to PC material.

Prices

PVC materials are cheaper, typically only half to a quarter of the price of PC materials.

Application

PC can be used as door and window glass, and PC laminates are widely used in protective windows in banks, embassies, detention centers and public places, as well as in aircraft cabin covers, lighting equipment, industrial safety baffles and bulletproof glass.

PVC materials are mostly used in the construction industry, packaging and other industries. For example, PVC materials can be used to make PVC pipes. PVC pipes have the advantages of easy construction, good corrosion resistance, low fluid resistance, good compressive strength, and long service life. We also It can be subdivided into different types such as drainage pipes, wiring pipes, medical pipes, etc. according to their uses.

Transparency

PC has high transparency, similar to glass, and can be used to make transparent plastic parts such as eyeglass frames and bottles.

In contrast, PVC has poor transparency and is usually translucent or milky white. Many plasticizers can be added to PVC, and after adding them, soft PVC can be added.

Chemical Stability

PVC has stable chemical resistant properties and is highly resistant to oxidants, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid.

It is also soluble in ethers, ketones, chlorinated aliphatic hydrocarbons and aromatic hydrocarbons. Organic solvents

PC has certain chemical corrosion resistance, resistance to weak acids and neutral oils, and is not resistant to strong acids and alkali. Dilute sodium hydroxide aqueous solution can slowly destroy it, and ammonia, amine or its 10% aqueous solution can cause it to rapidly saponify and degrade.

Mechanical Properties

PC has high mechanical strength, the highest impact strength among plastics, and can even be used as bulletproof material. This clear material forms well and is impact resistant. Its bending and tensile strength is equivalent to that of nylon, and it has high elongation and elastic modulus, but its fatigue resistance is low (less than nylon 66 ), lower compressive strength, better wear resistance (better than ABS), and small creep.

PVC has high mechanical strength, toughness and impact resistance. Its wear resistance at room temperature exceeds vulcanized rubber, and its hardness and rigidity are better than polyethylene.

Heat Resistance

PC Good heat resistance and cold resistance, wide temperature range, can be used for a long time at temperatures of -100℃-140℃, and still has certain toughness at -180℃.

PVC: Thermal stability and light resistance are poor. When it is above 100℃ or exposed to sunlight for a long time, it will decompose to produce hydrogen chloride, which will further auto-catalytically decompose and change color, resulting in a rapid decline in physical and mechanical properties and heat deflection . The use temperature is low (below 60℃)

Characteristics of PC Sheet Thermoforming

It is an amorphous plastic, and the temperatures that need to be controlled are different at different stages.

2) The thermal stability of PC sheet blister is relatively good and can be improved as the relative molecular weight increases.

3) PC sheet blister has good resistance to degeneration and good dimensional stability; but its internal stress is not easy to eliminate.

4) PC sheet blister is easily degraded when exposed to water at high temperatures, and the moisture content is required to be below 0.02% during molding.

5) Cracking may easily occur if care is not taken.

6) During the production process, the apparent viscosity of PC sheets is greatly affected by temperature and less affected by shear rate, and increases with the increase of relative average molecular weight.

7) PC sheet blister has no obvious melting point, the melt viscosity is high, and there are benzene rings in the PC molecular chain, so it is relatively rigid.

Special Processing Method for PC Sheet Thermoforming

Since the blister industry is a relatively new industry, there is currently no textbook-style process solution. We can only summarize relatively suitable processing methods through continuous exploration. In view of the process difficulties of PC material blister, including cracking due to stress, insufficient heating temperature and vacuum strength, and deformation caused by poor cooling, the industry has successively explored some special processing methods.

1) Sheet drying

In view of the fact that PC easily absorbs water, it is generally best to dry PC sheets before heating to absorb the internal moisture.

2) Control mold temperature

We must ensure that the anti-cracking ability and internal stress are balanced so that the cracking phenomenon of PC endurance boards will not occur.

3) Pay attention to molding and cooling time

It is necessary to strictly control the heating forming time not to be too long and ensure sufficient cooling time to prevent the sheet from deforming and curling.

4) Selection of blister machine

For the complex PC blister process, choosing a good blister machine is the first priority.

Characteristics of PVC Thermoforming

PVC sheet has high toughness and is not easy to burn. It will produce chlorine gas when burned, which will have a certain impact on the environment.

PVC is easy to heat seal and can be sealed with a sealing machine and high-frequency edge sealing. It is the main raw material for the production of transparent blister products. PVC sheet is a widely used and popular material.

PVC film can be divided into two types: environmentally friendly and non-environmental. It can be made into various blister packaging products such as transparent, colorful, anti-static, gold-plated, and flocked.

The main features are high transparency, good surface gloss, few crystal points, small water marks, wide use, strong impact resistance, and easy to form.

The products are widely used in toys, food, electronic products, medicine, electrical appliances, gifts, cosmetics, stationery, etc. Product outer packaging.

Conclusion

In conclusion, PC sheets and PVC sheets each have their own advantages and their disadvantages, and which one is better mainly depends on the specific use occasions and customerneeds. If you are more care about plastic part's performance and quality (such as temperature resistance, toughness, transparency), you may want to choose PC sheets. If you pay more attention to no pollution or low-cost needs during production process, then PVC may be a better choice.

A newly developed catalyst makes single-use plastics easier to upcycle, recycle and biodegrade

Researchers created a new catalyst that transforms hydrocarbons into chemicals and materials that are higher value, easier to recycle, and biodegrade in the environment. This catalyst transforms materials such as motor oil, plastics in single-use grocery bags, water or milk bottles, and their caps, and even natural gas. It was developed by a team of scientists led by Aaron Sadow, a scientist at Ames National Laboratory, director of the Institute for Cooperative Upcycling of Plastic (iCOUP), and professor of chemistry at Iowa State University.

The new catalyst is designed to introduce functional groups into aliphatic hydrocarbons. Aliphatic hydrocarbons are organic compounds made up of only hydrogen and carbon. They typically do not mix with water, instead creating distinct layers, partly because they do not contain functional groups. Functional groups are specific groupings of atoms within molecules that have unique characteristics. Adding functional groups to these hydrocarbon chains can drastically affect their properties and make the materials recyclable.

"Methane in natural gas is the simplest of hydrocarbons with nothing but carbon-hydrogen (CH) bonds. Oils and polymers have chains of carbon atoms, linked by carbon-carbon (CC) bonds," Sadow explained.
