Shaping the human face: Periosteal bone modeling across ontogeny

The Anatomical Record, EarlyView.
Abstract Facial morphology is a defining aspect of Homo sapiens that distinguishes our species from fossil ancestors and plays a central role in estimating age, sex, and ancestry in both past and present populations. Understanding how the face develops during postnatal ontogeny is essential for interpreting adult facial variation.

Characterization of fume particles generated during arc welding with various covered electrodes

Scientific Reports, 2018
Arc welding operations are considered to be risky procedures by generating hazardous welding fume for human health. This study focuses on the key characteristics, as well as dispersion models, of welding fumes within a work zone.

Insight Into Puncture‐Induced Thermal Runaway in Lithium‐Ion Batteries to Reduce Fire Risks in Electric Vehicle Collisions

Battery Energy, EarlyView.
This review examines nail penetration‐induced thermal runaway (TR) in lithium‐ion batteries, analyzing experimental and modeling studies on critical factors—battery materials, nail properties, state of charge, and penetration dynamics. It also explores internal short‐circuit modes, TR severity, and safety solutions such as advanced separators, non ...

The Reduction of Group 6–8 Transition Metal Oxides with Hydrogen—From Ore Smelting to Reaction Pathways#

European Journal of Inorganic Chemistry, EarlyView.
As the reduction of transition metal oxides by coal poses a significant climate risk, the use of alternative reducing agents such as hydrogen is becoming increasingly important. This review summarizes the current knowledge of the reduction pathways of transition metal oxides from groups 6 to 8.

Mechanochemically Synthesized Transition Metal Carbide Fillers for Coating Metallic Bipolar Plates in Proton Exchange Membrane Fuel Cells

Energy Technology, EarlyView.
Mechanochemically synthesized Cr3C2 and Mo2C, incorporated in a polyurethane‐based binder matrix, and applied to stainless steel, show the lowest contact resistance. The Cr3C2 coating provides good corrosion performance, while the Mo2C coating is unable to protect the metal from corrosion.

Use of Cold Plasma for Phytosanitation and Decontamination of Food Products: A Review

Future Postharvest and Food, EarlyView.
Applications of cold plasma in food industry. ABSTRACT Consumers are increasingly demanding healthy and nutrient‐rich food. Although conventional thermal processing techniques (pasteurization, sterilization, and blanching) ensure food safety and extend shelf life, they often negatively impact nutritional value and sensory quality, and they also consume
