a break from the anti semetic nonsense - because i am buying all my Computer Parts from Amazon (my REDACTED pc part shop keeps selling out of mobo ram cpu bundles and if i give jeff bezos money it will at least get to my house all at once) and i also need thermal paste, rec me some good thermal paste on Amazon. (giving you a Task to Distract you.) Asking publically so that other people can see your good taste in thermal paste and other computer goods.

I have two (2) separate recs for thermal paste.

If you are an every day PC user looking to do a standard hardware upgrade and you want something cost effective, easy to use, hard to fuck up, and perfectly sufficient for most gaming, you want Thermal Grizzly's Kryonaut. This is available basically everywhere, including Amazon. It's super popular and for good reason.

It's a non-conductive grease paste. That means it has a thick texture that is unlikely to squish out between your processor and heatsink, and even if it did squish out a bit, it wouldn't cause an electrical short.

But let's say you're on that next level shit. You know want some Fucked Up thermal paste for Pushing Limits, and you're ready to take some risks.

Oh baby.

Oh baby.

For that, I have to recommend Cool Labs Liquid Ultra

This is a highly liquid, highly conductible thermal paste. It is NOT safe for all coolers! If you have an aluminum heatsink you MUST NOT USE THIS TYPE OF PASTE. It will destroy your heatsink and possibly your processor.

But if you have 1) a copper heatsink 2) a steady hand 3) a lot of acetone 4) qtips?

Bro liquid metal gets you fucked UP cooling effects. Like 10x the cooling effect of a grease paste.

You must be extremely careful when applying it, however. Because it is liquid and metal, it can squish out from your heatsink and processor, and onto the motherboard or processor pins. If this happens, you may be able to clean it up with immense patience and acetone.... and you also may permanently destroy your computer with an irreparable electrical short.

You HAVE to be CAREFUL.

That said, it's not brain surgery. If you can like... draw a straight line, you've probably got enough dexterity to pull it off.

Some people use masking tape or electrical tape borders around their processors when applying liquid metal as a protective measure; you do then have to clean all the adhesive off with acetone, but it's a nice safety if you're anxious.

Though, tbh, for anyone who isn't like.... IDK, livestreaming 4K games or something, kryonaut is more than sufficient for your purposes.

Energy-Efficient Building Techniques in Tarneit

In reaction to the global movement towards sustainability, the construction industry in Tarneit, an emerging suburb of Victoria, has been integrated. In particular, house builders Tarneit can incorporate sustainable and efficient methods, materials, and technologies in building construction. 

These methods benefit the environment and are also financially sustainable for homeowners as they help cut down costs incurred in the provision of energy. This blog evaluates the various high-quality, energy-efficient building methods defining future housing in Tarneit.

Solar Power Integration

Integrating solar power systems is one of the most significant steps towards energy-efficient building. House builders in Tarneit increasingly embed solar panels and thermal systems in new constructions. Solar panels capture solar energy and directly convert it into electricity. 

Solar thermal structures harness sun energy to warm water, which reduces the use of steam on non-renewable power assets. This cuts carbon emissions and hence supports the environment while lowering utility expenses. 

Additionally, promoting incentives for solar power in Australia attracts new homeowners to embrace this power source.

Advanced Thermal Insulation

Proper insulation, therefore, plays a significant role in energy conservation, whereby temperatures within homes are well regulated, lowering the chances of using heaters or air conditioners frequently. House builders in Tarneit employ advanced insulation techniques, including foam insulation and high-quality batten insulation.

These materials are installed in the walls, roofs and floors as insulation and resist heat flow in cold and hot seasons. Insulation is crucial for making homes more comfortable by significantly reducing noise levels.

High-Efficiency Windows

Another strategy house builders in Tarneit use is installing energy-efficient windows to enhance home energy performance. Multiple-glazed or triple-glazed windows are made up of several glass panes separated by a gas with very low thermal conductivity. 

These windows also play a part in controlling indoor temperatures, preventing the formation of condense and giving better soundproofing. 

The frames employed in making these conservatories include fibreglass or composite frames, which are more energy-efficient and long-lasting.

Water-Saving Fixtures

Water performance in buildings is now considered one of the predominant additives of sustainable construction. In today's Tarneit homes, newer and more innovative houses feature energy and water-saving amenities such as low-flow toilets, showerheads, and faucets. 

Experienced house builders in Tarneit prefer these fixtures to minimise water usage in daily life while maintaining functionality without achieving high levels of water usage. 

By using significantly less water per minute compared to traditional fixtures, they help conserve a critical natural resource and lead to substantial savings on water bills. 

The deliberate incorporation of water-efficient technology in homes demonstrates a commitment to environmental stewardship and economic efficiency.

The desire for building materials plays a vital function in the environmental effect of a construction undertaking. House builders in Tarneit use recycled building materials that are not obtained directly from the source and have been recycled first. Some sustainable materials used in construction include recycled steel, glass, re-use wood and bamboo. 

Also, paints and adhesives are non-toxic, and sealants are used to reduce the emissions of VOCs, which harm the inhabitants of homes by providing them with good air quality.

Implementation of Smart Home Technology

Smart home technology is crucial today and significantly affects home energy management. Some of the features in houses in Tarneit include intelligent thermostats that control heating and cooling equipment depending on the number of people using the house and the climate. 

For instance, LED lighting consumes less energy than traditional lighting; programmable appliances and water heaters also help save energy. These technologies allow owners to screen their power consumption behaviour in detail and, for this reason, be in a function to make rational selections.

Green Roofs and Living Walls

Some innovative house builders in Tarneit are incorporating green roofs and living walls into new constructions. These characteristics provide good thermal performance, minimise the speed and impact of water on buildings, contribute to air quality, and diversify the avian fauna within cities. 

A green roof is a vegetative layer covered with vegetation and a growing medium or partially or fully developed plant layer on a waterproofing layer. 

Similarly, living walls are part of the building's exterior or interior walls, covered with plants. They enhance a building’s insulation and add aesthetic value to the property.

Optimal Orientation and Layout

This is a fact because the position of a building and its architecture determine how much energy it will consume. Climatically responsive architecture is apparent, where house builders in Melton strategically place numerous windows and doors to maximise natural light and air circulation within the buildings. 

Additionally, the structures are oriented in alignment with the direction of the winds and the sun. This approach minimises using artificial lights and mechanical air conditioners, thus saving power. 

Such thoughtful placement enhances energy savings and ensures that living spaces maintain a natural comfort throughout the seasons, creating healthier and more sustainable living environments.

Final Takeaway

Thus, the residents of Melton who choose to live in a house constructed with the following features can have a relatively environmentally friendly way of life meeting the ecological requirements of the contemporary world. Various dedicated house builders in Melton are adopting these building practices, paving the way for a future where all newly constructed homes will be as energy-efficient as possible, reflecting a commitment to environmental responsibility and sustainability.

2 min readPreparations for Next Moonwalk Simulations Underway (and Underwater) ESI24 Nam Quadchart SungWoo NamUniversity of California, Irvine Lunar dust may seem unimposing, but it presents a significant challenge for space missions. Its abrasive and jagged particles can damage equipment, clog devices, and even pose health risks to astronauts. This project addresses such issues by developing advanced coatings composed of crumpled nano-balls made from atomically thin 2D materials such as MoS₂, graphene, and MXenes. By crumpling these nanosheets—much like crumpling a piece of paper—we create compression and aggregation resistant particles that can be dispersed in sprayable solutions. As a thin film coating, these crumpled nano-balls form corrugated structures that passively reduce dust adhesion and surface wear. The deformable crumpled nano-ball (DCN) coating works by minimizing the contact area between lunar dust and surfaces, thanks to its unique nano-engineered design. The 2D materials exhibit exceptional durability, withstanding extreme thermal and vacuum environments, as well as resisting radiation damage. Additionally, the flexoelectric and electrostatically dissipative properties of MoS₂, graphene, and MXenes allow the coating to neutralize and dissipate electrical charges, making them highly responsive to the charged lunar dust environment. The project will be executed in three phases, each designed to bring the technology closer to real-world space applications. First, we will synthesize the crumpled nano-balls and investigate their adhesion properties using advanced microscopy techniques. The second phase will focus on fundamental testing in simulated lunar environments, where the coating will be exposed to extreme temperatures, vacuum, radiation, and abrasion. Finally, the third phase will involve applying the coating to space-heritage materials and conducting comprehensive testing in a simulated lunar environment, targeting up to 90% dust clearance and verifying durability over repeated cycles of dust exposure. This research aligns with NASA’s goals for safer, more sustainable lunar missions by reducing maintenance requirements and extending equipment lifespan. Moreover, the potential applications extend beyond space exploration, with the technology offering promising advances in terrestrial industries such as aerospace and electronics by providing ultra-durable, wear-resistant surfaces. Ultimately, the project contributes to advancing materials science and paving the way for NASA’s long-term vision of sustainable space exploration.

Steel and Aluminium

Why Can't Steel and Aluminum Be Welded Together?

Steel and aluminum are two of the most widely used metals in the manufacturing industry, each offering its unique set of properties that make them suitable for different applications. While both metals have significant strengths, including durability, strength, and resistance to corrosion, welding them together is a challenging task. This article will explain the reasons why steel and aluminum cannot be easily welded together and explore the issues involved.

1. Differences in Melting Points

One of the most fundamental reasons why steel and aluminum cannot be welded together easily is the significant difference in their melting points.

Steel typically melts at a temperature ranging from 1370°C to 1510°C (2500°F to 2750°F).

Aluminum, on the other hand, melts at a much lower temperature of approximately 660°C (1220°F).

When trying to weld the two metals, the higher melting point of steel creates a challenge. While aluminum can melt quickly, the steel requires much higher temperatures to reach its molten state. This discrepancy leads to issues such as the aluminum melting before the steel, making it difficult to form a strong, durable bond.

2. Dissimilar Material Properties

Steel and aluminum have fundamentally different material properties that affect their welding behavior. These differences include:

Thermal Conductivity: Aluminum has higher thermal conductivity than steel, meaning it dissipates heat faster. This can lead to difficulty in controlling the welding process and results in uneven heating. As aluminum cools rapidly, it may form brittle joints.

Expansion and Contraction: Steel and aluminum expand and contract at different rates when heated and cooled. This differential expansion can cause distortion and cracking in the welded area, making it challenging to create a reliable and strong bond between the metals.

3. Formation of Brittle Intermetallic Compounds

When welding steel and aluminum together, the heat causes the metals to interact at the molecular level, potentially forming intermetallic compounds. These compounds, such as iron-aluminum (Fe-Al) alloys, are brittle and can significantly weaken the joint. These brittle compounds do not have the same strength or ductility as either steel or aluminum, leading to a weak and unreliable weld that may fail under stress.

4. Welding Techniques and Equipment Challenges

Welding steel and aluminum together requires specialized techniques and equipment. Common welding methods, like MIG (Metal Inert Gas) or TIG (Tungsten Inert Gas) welding, are typically used for welding individual metals but may not be effective when trying to weld two dissimilar metals like steel and aluminum.

MIG Welding: MIG welding uses a filler material, but the heat input required to weld steel and aluminum together may be too high for the aluminum, leading to overheating and melting.

TIG Welding: TIG welding also faces similar issues due to the difficulty in managing the different melting points and heat behavior of the two metals.

To overcome these challenges, special techniques, such as laser welding or friction stir welding, may be used, but these methods are highly specialized and expensive.

5. Alternatives to Welding Steel and Aluminum Together

Although welding steel and aluminum together is impractical in most cases, there are alternative methods to join these two materials effectively:

Mechanical Fastening: Steel and aluminum can be connected using mechanical fasteners, such as bolts, screws, or rivets, which avoid the challenges of welding. This method is often used in industries like aerospace and automotive manufacturing.

Brazing: Brazing is a process in which a filler metal is used to join the materials at a lower temperature than welding. While brazing aluminum to steel can be more successful than welding, it still requires careful control of the temperature to prevent damaging the materials.

Adhesive Bonding: High-strength adhesives are also an option for joining steel and aluminum, providing a bond without the heat-related challenges that welding presents.

Conclusion

Steel and aluminum are both essential materials in modern manufacturing, but welding them together is problematic due to their differences in melting points, thermal properties, and the potential formation of brittle intermetallic compounds. While traditional welding methods like MIG or TIG welding are not suitable for these two metals, alternative techniques such as mechanical fastening, brazing, and adhesive bonding provide practical solutions for joining them. Understanding the limitations and potential solutions is key for engineers and manufacturers when working with these metals in various applications.
