I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Researchers discover new phase of nanoconfined water” Water molecules inside a crystal. Credit: Daria Sokol, MIPT Researchers at MIPT Laboratory of Terahertz Spectroscopy together with their Russian and international colleagues discovered a new phase of nanoconfined water; separate water molecules that are confined within nanocavities formed by ions of cordierite crystal lattice. The first reliable…
“#Engineers manipulate color on the nanoscale, making it disappear” The researchers experimented with nanoscale strips of a two-dimensional semiconductor, tungsten disulfide, arranged on a gold backing. Credit: University of Pennsylvania Most of the time, a material’s color stems from its chemical properties. Different atoms and molecules absorb different wavelengths of light; the remaining wavelengths are…
“#Why nanomaterial quality matters, and the smart new way to check it” Optical microscope image of stacked graphene layers. Credit: Dr Matt Large A new way to check the quality of nanomaterials like graphene has emerged from a team at the University of Sussex. Graphene and nanomaterials have been touted as wonder materials, and they…
“#Nanocrystals from recycled wood waste make carbon-fiber composites tougher” Electron micrograph of cellular nanocrystals on the carbon fibers. Credit: Dr. Amir Asadi/Texas A&M University College of Engineering Polymers reinforced with ultra-fine strands of carbon fibers epitomize composite materials that are “light as a feather and strong as steel,” earning them versatile applications across several industries….
“#Discovery of massless electrons in phase-change materials provides next step for future electronics” (Left) Crystal structure for the intermixed crystalline phase of the phase-change compound GeSb2Te4. (Middle) Angle-resolved photoemission spectrum of crystalline GeSb2Te4 by showing the linearly dispersive band crossing the Fermi level.

“#Researchers use nanocellulose to create materials with new properties” Nanocellulose decorated with metal nanoparticles. Credit: Magnus Johansson When nanocellulose is combined with various types of metal nanoparticles, materials are formed with many new and exciting properties. They may be antibacterial, change color under pressure, or convert light to heat. “To put it simply, we make…
“#Using viscous metals in micro fibers” Credit: Wei Yan/EPFL EPFL scientists have developed the first micro-structured fibers with a viscous metal inside—a perfect example of what cross-disciplinary teamwork can achieve. Platinum, copper, nickel and phosphorous—those are the components of an amorphous metal alloy with excellent mechanical properties. The alloy is also very corrosion-resistant and attract…
“#Novel approach improves graphene-based supercapacitors” An efficient pathway to improve performance of supercapacitors. Credit: Dawei Su Demand for integrated energy storage devices is growing rapidly as people rely more and more on portable and wireless electronics, and the global need grows for clean energy sources such as solar and wind energies. This is creating an…
“#A new synthesis method for three-dimensional nanocarbons” A new synthesis method creates curved octagonal structures by linking benzene rings. Credit: Issey Takahashi A team of scientists led by Kenichiro Itami, Professor and Director of the Institute of Transformative Bio-Molecules (WPI-ITbM), has developed a new method for the synthesis of three-dimensional nanocarbons with the potential to…
“#Nanoreactor strategy generates superior supported bimetallic catalysts” Synthesis of supported PdAu BNPs (monolith) using nanoreactor strategy. Credit: TIAN Zhengbin Supported bimetallic catalysts are an important class of catalysts in heterogeneous catalysis. They can be applied in various fields, such as electrocatalysis, biomass conversion, and hydrogen production. However, traditional impregnation and immobilization methods for synthesizing supported…
