Antimicrobial Masks as Personal protective equipment
Shortage of personal protective equipment (PPE) is often projected in response to public health emergencies such as infection outbreaks and pandemics. Respiratory protective devices (RPDs), namely medical face masks and respirators, are considered the last defence for the front-line healthcare workers. To contribute to the mitigation of RPDs shortage, new technology such as antimicrobial treated PPE that can reduce the risks of fomite during the donning and doffing process with an extended lifespan gets increasingly prevalent.

Self-Healable Lithium-Ion Batteries
The inner constituents of lithium-ion batteries (LIBs) are easy to deform during charging and discharging processes, and the accumulation of these deformations would result in physical fractures, poor safety performances, and short lifespan of LIBs. The introduction of self-healing (SH) materials into electrodes or electrolytes can bring about great enhancements in their mechanical strength, thus optimizing the cycle stability of the batteries. Due to the self-healing property of these special functional materials, the fractures/cracks generated during repeated cycles could be spontaneously cured.

Medicinal Chemistry of Analgesic and Anti-Inflammatory Quinazoline Compounds
Quinazoline is an essential scaffold, known to be linked with various biological activities. Some of the prominent biological activities of this system are analgesic, anti-inflammatory, anti-hypertensive, anti-bacterial, anti-diabetic, anti-malarial, sedative–hypnotic, anti-histaminic, anti-cancer, anti-convulsant, anti-tubercular, and anti-viral activities. This diversity in the pharmacological response of the quinazoline system has encouraged medicinal chemists to study and discover this system and its multitude of potential against several biological activities.

Microstructure Formation and Processing Features of Non-Alloy Steels
The properties of structural steel during processing are influenced by various structural components, including equilibrium structures, which include austenite and pearlite, as well as non-equilibrium structures like martensite, residual austenite, sorbite, and troostite. The formation of these structures is determined by factors that include temperature, alloy composition, and cooling medium.

Wild Boar Carcass Characteristics and Meat Quality
Globally, wild boar is a primary food resource, mostly for remote rural communities outside of large urban centers located in Latin America, Asia, and Africa. In Chile, the production of meat from European wild boar (Sus scrofa L.) is expanding together with the export of this “exotic” meat. Furthermore, in the Finno-Scandinavian peninsula, and central and Mediterranean Europe, wild boar (Sus scrofa) and other game species meat (reindeer, red deer, roe deer, fallow deer, moose, and chamois) can be found in local restaurants and fairs, indicating an already consolidated gastronomic interest in this type of meat.

Sulfide-Based Photocatalysts Using Visible Light
Sulfides are frequently used as photocatalysts, since they absorb visible light better than many oxides. They have the disadvantage of being more easily photocorroded. This occurs mostly in oxidizing conditions; therefore, they are commonly used instead in reduction processes, such as CO2 reduction to fuels or H2 production.

Formation of Reactive Species under Electron Irradiation
Electron-induced chemistry is relevant to many processes that occur when ionizing radiation interacts with matter. This includes radiation damage, curing of polymers, and nanofabrication processes but also the formation of complex molecules in molecular ices grown on dust particles in space. High-energy radiation liberates from such materials an abundance of secondary electrons of which most have energies below 20 eV. These electrons efficiently trigger reactions when they attach to molecules or induce electronic excitation and further ionization.

Biocatalyzed Redox Processes Employing Green Reaction Media
Biocatalysis can be defined in a broad sense as the mediation of chemical reactions by means of biological systems, including isolated enzymes, whole cells or cell-free extracts. In some circumstances, the aqueous buffer medium normally employed in biocatalytic procedures is not the best option to develop these processes, due to solubility and/or inhibition issues, requiring biocatalyzed redox procedures to circumvent these drawbacks, by developing novel green non-conventional media, including the use of biobased solvents, reactions conducted in neat conditions and the application of neoteric solvents such as deep eutectic solvents.

Nanoparticle–Biomolecule Conjugate
A nanoparticle–biomolecule conjugate is a nanoparticle with biomolecules attached to its surface. Nanoparticles are minuscule particles, typically measured in nanometers (nm), that are used in nanobiotechnology to explore the functions of biomolecules. Properties of the ultrafine particles are characterized by the components on their surfaces more so than larger structures, such as cells, due to large surface area-to-volume ratios. Large surface area-to-volume-ratios of nanoparticles optimize the potential for interactions with biomolecules.
