Flexible and wearable electronics generate localized heat that must be spread quickly without compromising mechanical stability or electromagnetic performance. A new study reports a flexible multifunctional heat spreader built from a reduced graphene oxide aerogel-based composite structure that addresses all…

A new numerical study maps how a thixotropic MXene nanofluid flowing past an inclined stretching cylinder generates entropy, with magnetic and structural viscosity parameters dominating surface drag and radiation dominating heat transfer. Subject of Research: Numerical simulation of thixotropic Jeffery…
A group of chemists and biologists at Nagoya University and Boston College, have succeeded in synthesizing a water-soluble warped nanographene molecule that is water soluble for the first time. This new molecule, recently described in the journal Angewandte Chemie International…
Kristin Breure, the CEO, President, and Board Chair of HydroGraph Clean Power Inc., is one of the scientists leading this movement. Having led HydroGraph from its early developmental stages to becoming a commercial-scale producer of high-purity graphene and advanced nanomaterials,…
Researchers report a simulated graphene-based terahertz MIMO antenna with a 1.33 THz bandwidth and machine learning-assisted optimization, though no prototype has yet been fabricated.
Metals, semiconductors and insulators are fundamental components of modern electronics. However, efforts to improve device performance have largely focused on semiconductor quality, while metal crystallinity has received far less attention. As transistor dimensions continue to shrink, though, structural disorder in…
Researchers at the University of Arkansas and the University of Michigan report a graphene-based energy harvester that converts ambient 60 Hz radiation from power lines into enough electricity to run a batteryless, nanowatt-scale temperature sensor.
A 20-nm atomic-layer-deposited Al2O3 buffer layer allowed researchers to separate substrate-induced strain from interfacial effects in solid-phase-crystallized germanium thin films, revealing that the local interface governs hole transport on sapphire, silicon, and quartz alike. Raman spectroscopy and X-ray diffraction showed that…
Graphene and other atom-thin materials, from MXenes and transition-metal dichalcogenides to boron nitride: how they are made, their chemistry and uses.
