High-speed Electronics to Process Info Faster Using Improved Material from Tellurium

Derived from tellurium, a rare element, a new two-dimensional material has been discovered by researchers from Purdue University. This material is said to improve current-carrying transistors all the way through a computer chip. It has been added to a list of two-dimensional, tremendously thin materials that engineers have employed to enhance transistors’ operation speed. This enables the facility of processing information faster in infrared sensors and other defense technologies and

Microwave Technology Made Better and Cheaper with Silicon Discovery

Using affordable silicon, researchers have discovered a way to generate microwaves with the help of powerful supercomputers. For self-driving automobiles, this breakthrough could come out as a boon as it substantially improves devices and reduces costs. Several years ago, University of Waterloo engineering professor, C.R. Selvakumar had already proposed this concept. Selvakumar said it was deemed impossible until now. Silicon is researched to be the second-most abundant substance available on

Tiny Valves Enable Individual Nanoparticles in Liquids to Sort and Separate

ETH Zurich researchers have recently developed nanovalves that allow control of individual nanoparticles’ flow in liquids. This control is enabled in tiny channels. Tiny valves developed by the researchers allow sorting and separation of the nanoparticles in liquids. The research could find interest in biomedicine, materials science, and other lab-on-a-chip applications. A wide scope of tiny particles, which include antibodies and other larger biomolecules, liposomes, virus particles, and semiconductor and

Development of Complex Biological Tissues with Help of New 3D Printer

An advancement brought about by a team from the UCLA Samueli School of Engineering is considered to be a part of the progress toward on-demand printing of complex artificial tissues that could be employed in surgeries such as transplants. With a view to allow therapeutic biomaterials to be built from multiple materials, a specially adapted 3D printer has been developed by the scientists. Findings of the study have been put

Cresol-based Solvents make Carbon Nanotubes as Usable as Common Plastics

Jiaxing Huang of Northwestern University has come up with a new technique to prepare disperse carbon nanotubes at unusually higher concentrations with the use of a simple, already mass produced, and inexpensive solvent called cresol. Interestingly, Huang found no need to use harsh chemical reactions or additives for modifying the nanotubes. Surprisingly, Huang also discovered that with increase in the concentrations of nanotubes, the material transitioned to a thick paste

Materials could be Delivered on Cue Using Resealable, Tiny Packets

A recipe that could mimic miniscule capsules delivering signaling molecules from one place to another in our bodies has been created by researchers from the University of Chicago. The announcement was made by Juan de Pablo, the university’s Institute for Molecular Engineering Liew Family Professor in the journal Nature Chemistry. Just as Ziploc bags, resealable, tiny synthetic packets created by the research team are said to release their contents at

Genetic Changes in Rat Brains Found with Persistent Exposure to Air Pollution

A Cedars-Sinai study has found the presence of cancer-related genes and inflammation triggered in the brains of rats due to extended exposure to air pollution particles in the Los Angeles Basin. The medical center’s Nanomedicine Research Center director, Julia Ljubimova, MD, PhD pointed out the role of nickel or certain other coarse air pollution materials in genetic changes associated with disease development. The study actually found markers that indicated their

Research Shows How to Build Better Beta Peptides Creating New Biomaterials

Researchers have brought to light probably for the first time the possibility of attaching self-assembling beta peptides onto dissimilar organic molecules. Posing challenges to bioengineers earlier, some molecules could now be put to use to create new varieties of materials. This research has been put out in the journal APL Bioengineering. Including a scaffold that could bear the growth of nerve cells, a range of beta-foldamers was aimed to prepare

Thin Smart Patch, Similar to Marine Skin Can Now Track and Monitor Behaviour of Marine Animals

In order to study the behaviour of marine animals, a smart patch called marine skin can be used. This thing Marine skin can be turned on a wide range of sea creatures in order to study the behaviour and is based on stretchable silicone elastomers which can be subjected to sharing, stretching, and twisting without getting affected. The Marine skin does not get affected even when exposed to high pressures

Time Crystals Found by Physicists at Yale

Physicists at Yale have discovered time crystals, which is a form of matter that takes when it is exposed to the pulses of electromagnetic waves. The discovery has led to several questions which need to be answered such as How are time crystals formed in the first place? Time crystals atoms spin periodically in One Direction and then in another due to a pulsating force which flips them and this
