“#Scientists look to bird feathers for printing colors” Structural colors are colors that are reflected when microscopic surfaces interfere with visible light. On the peacock, for example, tail feathers have brown pigment, or melanin, but their microscopic structure makes them reflect the dazzling colors we typically see in peacocks — blue, green and turquoise.

“#Bright early light of LEDs” Scientists are using supercomputers to gain insight on new materials that could make LED lighting even brighter and more affordable. New properties have been found in cubic III-nitrides LED materials useful for next-generation solid-state lighting. Credit: Tsai et. al, ACS Omega 2020, 5, 8, 3917-3923 LED lamps are lighting up…
“#Regulating the properties of a single crystal via voltage and application” a, no bias. b, appropriate bias and c, excessive bias is applied. Credit: by Jun Xing, Chen Zhao, Yuting Zou, Wenchi Kong, Zhi Yu, Yuwei Shan, Qingfeng Dong, Ding Zhou, Weili Yu and Chunlei Guo Lead halide perovskites can be turned into optoelectronic devices…
“#New biomaterial could shield against harmful radiation” Human cells treated with selenomelanin nanoparticles. Credit: Northwestern University Packing for outer space? Here’s one thing you won’t want to forget. Northwestern University researchers have synthesized a new form of melanin enriched with selenium. Called selenomelanin, this new biomaterial shows extraordinary promise as a shield for human tissue…
“#Researchers develop a unique method for creating powder composites” Credit: Pixabay/CC0 Public Domain Scientists from South Ural State University have developed a new method for creating powder metal composites. The method can reduce waste and improve the quality of electrical products and, as a result, increase the economic efficiency of production by 30%. The study…
“#Boron nitride destroys ‘forever’ chemicals PFOA, GenX” An illustration of the boron nitride photocatalysis that destroys the pollutant PFOA in water. Credit: Image courtesy of M. Wong/Rice University Rice University chemical engineers found an efficient catalyst for destroying PFAS “forever” chemicals where they least expected. “It was the control,” said Rice Professor Michael Wong, referring…
“#For cleaner air, water, and soil” Toxic chemicals stand no chance against a nanoshield created by scientists from IPC PAS. Photo made on site of the Front Modlin company. Credit: IPC PAS, Grzegorz Krzyzewski The air around us is getting more and more polluted. No wonder many scientists strive to find a way to purify…
“#’Growing’ active sites on quantum dots for robust hydrogen photogeneration” Schematic diagram of site- and spatial- selective integration of metal ions into QDs for robust H2 photogeneration. Credit: Prof. WU’s Group Very recently, Chinese researchers had achieved site- and spatial- selective integration of earth-abundant metal ions (e.g., Fe2 , Co2 , Ni2 ) in semiconductor…
