How does your computer smell?
Researchers create a highly sensitive biohybrid olfactory sensor
15-Jan-2021
A keen sense of smell is a powerful ability shared by many organisms. However, it has proven difficult to replicate by artificial means. Researchers combined biological and engineered elements to create what is known as a biohybrid component. Their volatile organic compound sensor can effectively ...
Catalyst transforms plastic waste to valuable ingredients at low temperature
07-Jan-2021
For the first time, researchers have used a novel catalyst process to recycle a type of plastic found in everything from grocery bags and food packaging to toys and electronics into liquid fuels and wax. "Plastics are essential materials for our life because they bring safety and hygiene to our ...
Inverted Fluorescence
Discovery of chromophores that emit light in the ultraviolet region when excited with visible light
23-Dec-2020
Fluorescence usually entails the conversion of light at shorter wavelengths to light at longer wavelengths. Scientists have now discovered a chromophore system that goes the other way around. When excited by visible light, the fluorescent dyes emit light in the ultraviolet region. According to ...
New procedure will reduce the need for rare metals in chemical synthesis
Researchers are working to improve the long-term sustainability of pharmaceutical and other chemical syntheses
02-Dec-2020
Pharmaceuticals, plastics, and many other chemical products have transformed human life. To prepare these products, chemists often use a catalyst--frequently based on rare metals--at various points in their syntheses. Although rare-metal catalysts are incredibly useful, their limited supply means ...
Catalyzing a zero-carbon world by harvesting energy from living cells
Scientists have achieved a breakthrough in converting energy-deficient metabolites to a biorenewable resource thanks to a versatile catalyst
16-Nov-2020
The imminent environmental crisis calls for an urgent transition to a green economy. A team of scientists at Nagoya University, Japan, led by Professor Susumu Saito, has recently found an interesting way to make this happen -- by leveraging an important metabolic pathway in living cells. Their ...
Tips for making nanographene
A new and efficient way to create nanographene for power and display devices
12-Nov-2020
Nanographene is a material that is anticipated to radically improve solar cells, fuel cells, LEDs and more. Typically the synthesis of this material has been imprecise and difficult to control. For the first time, researchers have discovered a simple way to gain precise control over the ...
Coating plastics by porous nanofilm
New method for creating metal-organic framework thin films
11-Nov-2020
A research team has developed a new method for creating metal-organic framework (MOF) thin films that can be applied to sensors and electric devices. Like sponges, porous materials contain pores. The pore size affects the property of the material. For example, small pores create more absorbent ...
Scientists grow carbon nanotube forest much longer than any other
Novel technique yields a carbon nanotube forest of record length, potentially revolutionizing the future of many industries
06-Nov-2020
Today, a multitude of industries, including optics, electronics, water purification, and drug delivery, innovate at an unprecedented scale with nanometer-wide rolls of honeycomb-shaped graphite sheets called carbon nanotubes (CNTs). Features such as light weight, convenient structure, immense ...
Well oriented: Catalysts for isotactic polar polypropylenes
Japanese scientists developed a new approach that allows more suitable catalysts to be produced much more easily
03-Nov-2020
Polypropylene (PP) is one of the most widely used plastics in the world. By controlling the spatial orientation of the propylene building blocks and additional polar components, it should be possible to create a new generation of attractive, engineered, specialty plastics, with improved ...
Gold- and bronze-like paints that don't contain metal
Researchers have developed organic-only dyes that can form films resembling gold or bronze, without the need for metals
19-Oct-2020
Lustrous metallic paints are used to enhance the beauty of many products, such as home decorations, cars and artwork. But most of these pigments owe their sheen to flakes of aluminum, copper, zinc or other metals, which have drawbacks. Now, researchers reporting in ACS Omega have developed ...
