In view of Corona pandemic, scientists have taken significant efforts to study and recognize the peculiarities of the SARS-CoV-2 outbreak in order to prevent it from spreading. It was discovered that the virus is spreading in many places and nations that have made significant progress in addressing environmental pollution or are not subject to dusty storms. Infections are growing again in the same country, with varied densities of sick persons depending on the weather and windy season. Sun and dust are safe techniques for the deactivation and disinfection of SARS-CoV-2. Here, we used metal oxide discs (FeO 9%, SiO 60%, CaO 6%, MgO 8%, and AlO 17%) to safely disinfect SARS-CoV-2 after being subjected to the sun for 30 min. As a result, all SARS-CoV-2 were destroyed completely by transmission electron microscope (TEM) after sun exposure. Three major countries have been chosen as case studies: Italy, China, and Iran. It was discovered that places subjected to dust currents have a lower spread of the coronavirus. This is owing to the fact that the dust contains about 90% metal oxide, which functions as a natural photocatalyst for the synthesis of oxygen and hydrogen. These oxidizing spices can kill SARS-CoV-2.

Waste three-way catalysts (TWCs) and waste LiCoO batteries represent critical environmental challenges due to hazardous components yet contain high-value resources, and their recycling has garnered widespread attention. We propose a novel 'waste-to-waste' synergistic recycling where spent LiCoO batteries reconstruct mineral phases of waste TWCs, enabling co-recovery of platinum group metals and Li/Co without traditional oxidants. However, the environmental performance of this process still requires further analysis.

Electron Fenton (EF) degradation often suffers from low in situ HO electrosynthesis and Fe regeneration. Herein, a novel multi-element oxide-sulfide heterostructure is reported, (FeVCoCuMn)O/(CuFeVCoMn)S, for efficient and stable EF degradation. The oxide-sulfide phase ratio is optimized through temperature control during the synthesis.

2D Bismuth oxycarbonate (2D BOC) nanosheets have a unique layered structure with many applications, including capture and reduction of carbon dioxide. Processing powdered elemental bismuth in water under ambient air conditions using a vortex fluidic device (VFD) results in the formation of 2D BOC without the need of surfactants or other excipients. The induced high shear mechanical energy in the form of micron/submicron topological typhoon like spinning top (ST) fluid flow drives the conversion, which we propose initially melts the metal particles which are spontaneously oxidised at the liquid-quartz tube interface to form 2D bismuth oxide (BiO).

Memtransistors are active analog memory devices utilizing ionic memristive materials as channel layers. Since their introduction, the term "memtransistor" has widely been adopted for transistors exhibiting nonvolatile memory characteristics. Currently, memtransistor devices possessing both transistor on/off functionality and nonvolatile memory characteristics include ferroelectric field-effect transistors (FeFETs) and charge-trap flash (floating gate), yet ionic memtransistors have not matched their performance.

Enhancing the energy conversion efficiency of fuel cells necessitates optimization of oxygen reduction reaction (ORR) under high-voltage conditions through improved Pt catalysis. This study introduces an electrocatalyst that uniformly anchors a high loading (40 wt%) of small Pt nanoparticles (3.2 nm) on a novel support: tellurium and nitrogen co-mediated graphitized mesoporous carbon (Te-N-GMC).
