Uniform Amorphization of Crystalline Silicon Surfaces Enabled by Deep Ultraviolet Femtosecond Laser Pulses

Advanced Engineering Materials, EarlyView.
Deep‐UV (258 nm) femtosecond pulses enable uniform amorphous silicon writing on Si(100)/(111) with a six‐fold larger fluence amorphization window than NIR methods. Optimized fluence and overlap yield 20–45 nm uniform and continuous amorphous layers. Microscopy shows sharp interfaces, and real‐time reflectivity reveals nanosecond melt–resolidification ...

Spatiotemporal Variability of Cloud Parameters and Their Climatic Impacts over Central Asia Based on Multi-Source Satellite and ERA5 Data

Remote Sensing
As key components of the climate system, clouds exert a significant influence on the Earth’s radiation budget and hydrological cycle. However, studies focusing on cloud properties over Central Asia are still limited, and the impacts of cloud variability ...

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Effect of Foot Bathing on Distal-Proximal Skin Temperature Gradient in Elders [PDF]

, 2008
Increased distal (foot)-proximal (abdominal) skin temperature gradient ( DPG) has been associated with better sleep initiation. Warm footbath can affect distal skin temperature to change DPG.

A CFD-based study on the heat transfer characteristics between the human body and the environment under low-temperature attire

Frontiers in Bioengineering and Biotechnology
In order to study the interaction between the human body, clothing, and environment in a low-temperature environment, a three-dimensional human thermoregulation model was established based on real human body scanning images.

Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry

Advanced Functional Materials, EarlyView.
In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...

Alpha-1 adrenoceptor stimulation triggers axon-reflex vasodilatation in human skin [PDF]

, 2009
The aim of this study was to determine whether pre-treatment of human skin with the α1-adrenoceptor antagonist terazosin would block vasoconstrictor responses and axon-reflex vasodilatation to the α1-adrenoceptor agonist methoxamine.

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Foot temperature responses during walking: a theoretical estimation of mechanical and physiological factors

Frontiers in Bioengineering and Biotechnology
Skin temperature has been previously associated with tissue complications (i.e., foot ulcers) in individuals with diabetes. Previous studies have suggested that mechanical factors during ground contact (i.e., foot shear force, foot net work), and ...
