I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Serendipity broadens the scope for making graphite” Credit: CC0 Public Domain Curtin University researchers have unexpectedly discovered a new way to make crystalline graphite, an essential material used in the making of lithium ion batteries. Described in a research paper published today in Communications Materials, the new technique does not require the typical metal catalysts…
“#4-D printed thermite could make welding in space and combat zones easier, safer” Neely’s has welded iron (above) and copper with the 4D printed thermite paste. Credit: Vanderbilt University A recent mechanical engineering doctoral graduate has created a material for welding in extreme conditions that could minimize equipment needed and operator hazards. The material—a safe,…
“#Tandem catalytic system efficiently converts carbon dioxide to methanol” Credit: Frank Tsung Converting carbon dioxide to methanol, a potentially renewable alternative fuel, offers an opportunity to simultaneously form an alternative fuel and cut down on carbon dioxide emissions. Inspired by naturally occurring processes, a team of Boston College chemists used a multi-catalyst system to convert…
“#A new MXene material shows extraordinary electromagnetic interference shielding ability” Researchers at Drexel and KIST reported that a new MXene material, titanium carbonitride, can shield the electromagnetic interference better than materials currently being used in electronics devices. Credit: Drexel University As we welcome wireless technology into more areas of life, the additional electronic bustle is…
“#Ionic spiderwebs that imitate dual functions in real spiderwebs” Credit: Unsplash/CC0 Public Domain A team of researchers from Seoul National University and Eumam Middle School has developed a type of ionic spiderweb that is able to imitate dual functions found with real spiderwebs. In their paper published in the journal Science Robotics, the group describes…
“#Scientists develop new material for longer-lasting fuel cells” Transmission Electron Micrograph of graphene decorated with platinum nanoparticles. The dark spots are the platinum nanoparticles and the grey sheet they lie on is the graphene support material. Credit: Patrick Cullen / Gyen Ming Angel New research suggests that graphene—made in a specific way- could be used…
“#Digitizing chemistry with a smart stir bar” The Smart Stirrer (above) can transmit data on the color, viscosity and other attributes of the solution it is stirring. Credit: Dmitry Isakov Miniaturized computer systems and wireless technology are offering scientists new ways to keep tabs on reactions without the need for larger, cumbersome equipment. In a…
“#Chemists make tough plastics recyclable” Credit: Unsplash/CC0 Public Domain Thermosets, which include epoxies, polyurethanes, and rubber used for tires, are found in many products that have to be durable and heat-resistant, such as cars or electrical appliances. One drawback to these materials is that they typically cannot be easily recycled or broken down after use,…
“#Invention offers new option for monitoring heart health” A team from Purdue University developed self-powered wearable triboelectric nanogenerators with polyvinyl alcohol-based contact layers for monitoring cardiovascular health. Credit: Wenzhuo Wu/Purdue University An invention may turn one of the most widely used materials for biomedical applications into wearable devices to help monitor heart health. A team…
“#How adding green tea extract to prepared foods may reduce the risk for norovirus” Infusing prepared foods with an edible coating that contains green tea extract may lower consumers’ chances of catching the highly contagious norovirus by eating contaminated food, new research suggests. Norovirus, which causes vomiting and diarrhea, sickens an estimated 48 million people…
