Novel method developed for phosphorescent multi-color carbon dots

A research team has devised a novel method to prepare carbonized polymer nanodots capable of emitting multi-color ultra-long room-temperature phosphorescence (RTP) from blue to green. "These materials exhibit potential applications in anti-counterfeiting and information encryption," said Zhang Qipeng, member of the team. The research findings have been published in Advanced Science, and the study was led by Jiang Changlong from Hefei Institutes of Physical Science of Chinese Academy of Sciences RTP materials glow even after the light source is removed, making them valuable for various uses like security features, data protection, displays, and medical imaging. Carbon dots (CDs) are a kind of RTP material known for being easy to make, stable under light, and safe. But making bright and long-lasting RTP materials with CDs is tough due to non-radiative loss of energy.

Zapping cobalt nanodots could lead to magnetic RAM

Magnetic storage, and we’re talking tape right here, is good for very long-expression storage since it’s low-priced and stable — unlike strong point out drives and volatile memory, which are speedy but high priced and far better for short term storage. New analysis may well direct to a strategy that combines the finest of the two worlds.

The primary issue with magnetic storage is that it…

hmm. Po-210 has a rated thermal power output of 140W/g(!), and a half life of 4.5 months directly into stable lead, you could absolutely build the world's most dangerous stove with that and it would be able to roughly match these numbers with the small problem that you can't really turn it off. Also the insane toxicity and radiation output.

You'd only need 2g to boil a cup of water in under 3 minutes! You could just drop a cube of it in a mug. Someone should sell these. Polonium-210 is an alpha emitter I think? All the radiation would be pretty contained.

Co-60 is 20W/g but with a five-year half life, so that's also useful, however I think market penetration would be hurt by the necessary "DROP AND RUN" warnings.

Plutonium-238 is weaksauce by comparison, at a meager 0.5W/g, which is why any time you've seen a photo of glowing red plutonium, it either means there was a LOT of it, or, more likely, it was recently covered in an insulating blanket.

In the Left Hand or Darkness, the Gethenian Stove is claimed to be able to run continuously for 14 months. If we assume a (somewhat conservative) heat output of 700W, that's 7.2GWh, or equivalent to 740 liters or 195 gallons of petrol in energy capacity, in a device that weighs 4 lbs, or about 1.8kg. Modern hiking stoves are closer to 1.5-2kW in heat output, so that could be double or triple the energy!

Nanodots made of photovoltaic material support waveguide modes

Antimony sulfide, or stibnite (Sb2S3), has been investigated intensively in recent years as a promising material for nontoxic, environmentally friendly solar cells. It is now possible to fabricate thin photovoltaic films from an ink containing nanoparticles of stibnite, and to nanopattern those films for 2-D and 3-D structures of pretty much any shape. Such simple, cost-effective production methods fulfill prerequisites for reliable, widespread use.

Since stibnite is an effective semiconductor (i.e., it has a high absorption coefficient and carrier mobility), its nanostructure holds promise as a photoswitchable material for all-optical signal processing and computing. Petra Groß, researcher at the Institute for Physics at University of Oldenburg explains, "Illumination with near-infrared light, with wavelengths for which stibnite is largely transparent, can result in an ultrafast change of its refractive index. This means that a surface patterned with stibnite nanoparticles could enable optical properties like reflection of color appearance to be switched by an infrared light pulse."

Researchers have used carbon dots, created from human hair waste sourced from a barbershop, to create a kind of ‘armor’ to improve the performance of cutting-edge solar technology.

In a study, the researchers led by Professor Hongxia Wang in collaboration with Associate Professor Prashant Sonar of QUT’s Centre for Materials Science showed the carbon nanodots could be used to improve the performance of perovskites solar cells.

Perovskites solar cells, a relatively new photovoltaic technology, are seen as the best PV candidate to deliver low-cost, highly efficient solar electricity in coming years. They have proven to be as effective in power conversion efficiency as the current commercially available monocrystalline silicon solar cells, but the hurdles for researchers in this area is to make the technology cheaper and more stable.

Unlike silicon cells, they are created with a compound that is easily manufactured, and as they are flexible they could be used in scenarios such as solar-powered clothing, backpacks that charge your devices on the go and even tents that could serve as standalone power sources.

This is the second major piece of research to come as a result of a human hair derived carbon dots as multifunctional material.

Last year, Associate Professor Prashant Sonar led a research team, including Centre for Materials Science research fellow Amandeep Singh Pannu, that turned hair scraps into carbon nanodots by breaking down the hairs and then burning them at 240 degrees celsius. In that study, the researchers showed the carbon dots could be turned into flexible displays that could be used in future smart devices.

In this new study, Professor Wang’s research team, including Dr Ngoc Duy Pham, and Mr Pannu, working with Professor Prashant Sonar’s group, used the carbon nanodots on perovskite solar cells out of curiosity. Professor Wang’s team had previously found that nanostructured carbon materials could be used to improve a cell’s performance.

After adding a solution of carbon dots into the process of making the perovskites, Professor Wang’s team found the carbon dots forming a wave-like perovskite layer where the perovskite crystals are surrounded by the carbon dots.

“It creates a kind of protective layer, a kind of armour,” Professor Wang said.

“It protects the perovskite material from moisture or other environmental factors, which can cause damage to the materials.”

The study found that perovskite solar cells covered with the carbon dots had a higher power conversion efficiency and a greater stability than perovskite cells without the carbon dots.

Professor Wang has been researching advanced solar cells for about 20 years, and working with perovskite cells since they were invented about a decade ago, with the primary objective of developing cost-effective, stable photovoltaics materials and devices, to help solve the energy issue in the world.

“Our final target is to make solar electricity cheaper, easier to access, longer lasting and to make PV devices lightweight because current solar cells are very heavy,” Professor Wang said.

“The big challenges in the area of perovskite solar cells are solving stability of the device to be able to operate for 20 years or longer and the development of a manufacturing method that is suitable for large scale production.

“Currently, all the reported high-performance perovskite solar cells have been made in a controlled environment with extremely low level of moisture and oxygen, with a very small cell area which are practically unfeasible for commercialization.

“To make the technology commercially viable, challenges for fabrication of efficient large area, stable, flexible, perovskite solar panels at low cost needs to be overcome.

“This can only be achieved through a deep understanding of the material properties in large-scale production and under industrially compatible conditions.”

Professor Wang is particularly interested in how perovskite cells could be used in the future to power spacecrafts.

The International Space Station is powered by four solar arrays, which can generate up to 120 kW of electricity. But one disadvantage of the current technology of space PVs is the weight of the payload to get them there.

While perovskite would be much lighter, one of the challenges for researchers is to develop perovskite cells able to cope with the extreme radiation and broad range of temperature variation in space—from minus 185 degrees to more than 150 degrees Celsius.

Professor Wang said the solution could be ten years off, but researchers were continuing to gain greater insights in the area.

Currently Professor Wang’s research team is collaborating with Professor Dmitri Golberg in the QUT Centre for Materials Science to understand the properties of perovskite materials under extreme environmental conditions such as strong irradiation of an electron beam and drastic temperature change.

“I’m quite optimistic given how much this technology has improved so far,” Professor Wang said.

Prof. Bambang Purwono Dikukuhkan Sebagai Guru Besar UGM

BALIPORTALNEWS.COM, YOGYAKARTA - Prof. Drs. Bambang Purwono, M.Sc., Ph.D., dikukuhkan sebagai Guru Besar bidang Ilmu Kimia pada Departemen Kimia FMIPA-UGM di Balai Senat UGM, Selasa (11/10/2022). Dalam pidato pengukuhan berjudul Kemosensor: Prospek Pengembangan dan Tantangannya di Era Industri 4.0, Bambang menyebutkan kemosensor sangat diperlukan dalam mendukung deteksi senyawa kimia, monitoring lingkungan, identifikasi senyawa-senyawa kimia dan senyawa pencitra (imaging compounds). Namun dewasa ini analisis senyawa kimia yang memerlukan ketelitian dan akurasi tinggi membutuhkan instrument canggih dengan biaya dan investasi yang tinggi. Berkaca dari pengalaman pandemi Covid-19 telah memberikan pelajaran berharga akan pentingnya alat diagnosis yang cepat dan akurat. Alat PCR yang akurat masih memerlukan waktu yang relatif lama untuk mendapatkan hasil. “Oleh karena itu tidak dapat dibayangkan apabila alat-alat canggih ini dapat tergantikan dengan peralatan yang sederhana, portable, dapat dioperasikan oleh orang awam, waktu analisis yang cepat dan memiliki hasil dengan presisi dan akurasi yang memadai seperti kemosensor,” paparnya. Bambang mengatakan bahwa cara deteksi kemosensor cukup sederhana dan mudah. Kendati begitu, pengembangannya sangat bergantung pada analit yang dideteksi, senyawa kemosensor yang dipakai, dan tipe kemosensor yang digunakan. Senyawa kemosensor dapat berasal dari hasil sintesis maupun bahan alam. Kemosensor kolorimetri (warna) dapat dibuat dari senyawa sintesis  maupun bahan alam yang memiliki struktur kimia yang mirip/identik. Bambang menyampaikan salah satu contoh kemosensor yang paling tua dan sudah dikenal luas adalah kertas pH. Bahan ini digunakan untuk mendeteksi sifat keasaman atau kebasaan suatu materi. Strip pH ini mampu membedakan derajat pH suatu larutan dengan teliti tanpa perlu menggunakan alat pH meter, cara kerja sederhana, murah operasinya, praktis dengan tidak membutuhkan reagensia standard. Selain bahan sintetik yang bisa digunakan sebagai kemosensor, bahan alam juga dapat digunakan sebagai kemosensor kolorimetri yang berasal dari tumbuhan, hewan, maupun mineral. Zat warna alami ini sudah dimanfaatkan sebagai pewarna kain (industri batik), makanan, obat dan kosmestik. “Pengujian secara sederhana mendeteksi kandungan boraks pada makanan dapat menggunakan kemosensor kolorimetri,” tuturnya. Bambang menyebutkan zat warna alami telah digunakan sebagai kemosensor yang untuk mendeteksi atau penanda kesegaran produk pangan. Contonya pada produk-produk laut seperti udang, ikan, cumi, dan lainnya mudah rusak dengan menghasilkan senyawa-senyawa amina yang menimbulkan bau dan peningkatan pH. Zat warna alami dari kunyit atau antosianin dapat digunakan untuk mendeteksi kesegaran ikan. Ikan yang mulai mengalami kerusakan akan memberikan perubahan warna kurkumin/antosianin yang berbeda dari warna asal kurkumin (kuning) atau antosianin (merah). Kemosensor berbahan dasar biomass juga berkembang dengan cepat sejak ditemukaannya material karbon yang diberi nama Karbon nanodot (C-Dots). Beberapa bahan biomassa seperti kulit telur, rumput, kulit buah, dan daun juga telah digunakan sebagai bahan dasar sintesis C-Dots dengan metode bottom-up. Bahan lain yang menarik untuk dikembangkan sebagai C-Dots dikatakan Bambang adalah ampas kopi. Potensi pengembangan C-Dots dari ampas kopi ini sangat besar melihat produksi kopi seluruh dunia pada tahun 2021 mencapai 10,2 juta ton. Ampas kopi berisikan bahan organik tinggi yang tidak mudah terdegradasi seperti tannin, kafein dan lemak. Bahan ini dapat digunakan untuk senyawa pendeteksi besi, tembaga, sodium siklamat dalam makanan dan pencitraan sel kanker HeLa. Bambang menyebutkan Penggunaan teknologi informasi yang digabungkan dengan kepentingan Color Changing Sensor CCS menjadi trend baru dalam kimia analisis. Ditambah dengan pemanfaatan smartphone dan IoT semakin memodernisasi teknologi analisis kimia Dengan teknik ini, biaya analisis menjadi rendah dan hasil segera diperoleh. “Hasil pengembangan kemosensor dengan bantuan IT membuat aplikasi kemosensor dalam kehidupan sehari-hari menjadi mudah, murah, dan real-time. Fungsi laboratorium analisis kimia akan berkurang karena akan tergantikan oleh kemosensor,” urainya.(bpn) Read the full article
