Researchers develop graphene-based foam composite for efficient water filtration

While graphene-based materials have potential as adsorbent materials, their performance can be hindered due to aggregation and a lack of control over their porosities and dimensions. The researchers in a recent study, from the University of Exeter, Kyushu University and the University of Oxford, have addressed this issue by developing a unique graphene material combined with a high porosity composite foam to combat aggregation.

Pharmaceuticals are among the most prominent emerging contaminants (ECs) in water systems. They may cause severe environmental consequences along with potential health problems. To successfully eradicate ECs from processed wastewater streams, effluent and drinking water purification facilities must adopt adequate tertiary treatment methods. Adsorption is regarded as a technology with great potential in water treatment as it is dependable and less expensive compared to reverse osmosis, oxidizing, microfiltration, ultrafiltration, ion exchange, etc.

Researchers succeed in synthesizing single layers of hexagonal boron nitride on graphene

A research team led by the University of Michigan has developed a reliable, scalable method for growing single layers of hexagonal boron nitride on graphene.

Graphene-hBN structures can power LEDs that generate deep-UV light, which is impossible in today's LEDs, said Zetian Mi, U-M professor of electrical engineering and computer science and a corresponding author of the study. Deep-UV LEDs could drive smaller size and greater efficiency in a variety of devices including lasers and air purifiers.

Researchers detect evidence of strong electron correlation in a trilayer graphene/hBN moiré superlattice

Researchers from MIT, Harvard University, University of California at Berkeley, Lawrence Berkeley National Laboratory, China's Shanghai Jiao Tong and Fudan Universities and Japan's National Institute for Materials Science have taken a significant step toward understanding electron correlations.

In their new study, the researchers revealed direct evidence of electron correlations in a two-dimensional material called ABC trilayer graphene. This material has previously been shown to switch from a metal to an insulator to a superconductor.

Redmi K50 e-sports version sports an advanced graphene-based cooling system

Graphene-based cooling systems are becoming quite popular in today's cellphones, with many companies using it in their models. A few examples are: realme's GT 2 series, ZTE's Axon 30, Xiaomi's Mi 10 Ultra, various Huawei phones and more.

REDMI K50 E-SPORTS uses graphene cooling systems image

Now, it seems that Redmi's K50 e-sports has joined this team, with a recent disassembly test that found that its heat dissipation system makes use of graphene films. The test also reported 3D high-power graphite, large-area double VC, and heat dissipation copper sheet + boron nitride.

Graphene and hBN nano-additives improve eco-friendly lubricant oils

Researchers from the University of Nevada have investigated the introduction of graphene nanoplatelets (GNPs) and hexagonal boron nitride (hBN) to canola oil to improve its tribological properties, as part of an effort to reduce the usage of lubricants based on petroleum as lubricants for reducing abrasion and friction.

Three nanoscale lubricating combinations were created by combining both GNP and hBN settings in varied ratios to get the best beneficial synergy. The team reports that lubrication quality and performance may be increased by using low-weight percentages of nanoparticle (NP) and microparticle additions. One benefit is that it has a reduced coefficient of friction (COF) and wearing.
