Thibado and his colleague, assistant professor Pradeep Kumar, discovered the potential of two-dimensional materials while observing the motion of graphene, a two-dimensional form of carbon, mounted on a copper grid. Using a high-powered microscope, they observed that the freestanding graphene …
Crumpled graphene balls to enhance Li-ion batteries by preventing dendrite growth
Researchers at Northwestern University in the U.S have designed a way to use “crumpled graphene balls” to improve Li-ion batteries. The team explained that in current batteries, lithium is usually atomically distributed in another material like graphite or silicon in the anode. However, using an additional …
Building better batteries using crumpled graphene balls
The team at Northwestern University’s approach actually builds on a type of graphene it developed back in 2011. Literally taking inspiration from a trashcan of scrunched up paper, the engineers came up with a way of crumpling graphene sheets into balls by first atomizing them into tiny water droplets.
UK Researcher Unveils World's First Automotive Graphene Composite Component Prototype
Ahmed Elmarakbi, an automotive composites professor at the University of Sunderland (UK), has produced a prototype of the world’s first graphene composite component for an automotive application. Elmarakbi is leading Task 10.11 – Composites for Automotive, part of the European Commission’s …
2-D tin (stanene) without buckling: A possible topological insulator
In its wake have followed a host of “post-graphene materials” – structural analogues of graphene made of other elements like silicon or germanium. Now, an international … Just as graphene differs from ordinary graphite, so does stanene behave very differently to humble tin in bulk form. Because of …
Polymer Nanocomposites for Electromagnetic Interference Shielding – Computing and Technology …
The book explores the use of polymer composites with carbon nanomaterials (such as single walled carbon nanotubes, multiwalled carbon nanotubes, carbon nanofibers, and graphene) providing the required level of conductivity. In comparison to conventional metal-based EMI shielding materials, …
Graphene Market (2-DTech Limited, ACS Material) Analysis & Forecast
HTF MI presents an in-depth assessment of current Graphene key market drivers, market size and trends and EMEA (Europe, Middle East and Africa) Graphene opportunities, challenges, and restraints as well as key market segments, technological updates, impact of any regulatory policies as well as …
Using crumpled graphene balls to make better batteries
Lithium metal-based batteries have the potential to turn the battery industry upside down. With the theoretically ultra-high capacity of lithium metal used by itself, this new type of battery could power everything from personal devices to cars. “In current batteries, lithium is usually atomically distributed in …
Could GRAPHENE (OTCMKTS:GRPEF) Go Up After Its Newest Short Interest Report?
The stock of GRAPHENE (OTCMKTS:GRPEF) registered an increase of 7.44% in short interest. GRPEF’s total short interest was 116,900 shares in January as published by FINRA. Its up 7.44% from 108,800 shares, reported previously. With 182,300 shares average volume, it will take short sellers 1 …
Researchers use crumpled graphene balls to avoid dendrite growth on Li-metal anodes
Researchers at Northwestern University and Tianjin University now report an effective approach to avoiding dendrite growth on Li-metal anodes by using a scaffold based on crumpled paper ball-like graphene (CGB) particles. An open-access paper on their work is published in the journal Joule.
