Effect of foot immersion and neck cooling on renal, intestinal, immune and inflammatory markers in older adults exposed to extreme heat

open access: yesExperimental Physiology, EarlyView.
Abstract Older adults with reduced thermoregulatory capabilities are increasingly at risk of heat‐related pathophysiological outcomes (e.g., acute kidney injury, heatstroke) due to increasingly frequent, prolonged and intense heatwaves. Foot immersion and neck cooling have been proposed as practical, non‐electrical cooling strategies for protecting ...

Thermionic electron emission from single carbon nanostructures and its applications in vacuum nanoelectronics

open access: yes, 2017
Nanoscale electron sources with high electron-emitting performance are of great interest in vacuum nanoelectronics. Resembling traditional thermionic emission sources based on a hot tungsten filament, a hot carbon nanotube or graphene can function as a ...

Quantifying nitrogen release behavior of enhanced efficiency fertilizers in rainfed cotton through field‐based and combustion methods

open access: yesAgricultural &Environmental Letters, Volume 11, Issue 2, December 2026.
Abstract The effectiveness of enhanced efficiency nitrogen fertilizers (EENFs) depends on how well the nitrogen (N) release synchronizes with crop demand. A 2‐year (2024–2025) mesh‐bag study was conducted to quantify N release from six N fertilizer sources under field conditions.

Electrolysis‐treated biosolids enhance wheat growth and alter soil health parameters

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Biosolid‐based fertilizers can benefit agriculture by supporting circular nutrient economies, reducing fertilizer costs, and minimizing environmental impacts compared to inorganic fertilizers. A 125‐day greenhouse experiment was conducted to assess the effects of electrolysis‐treated biosolids on wheat (Triticum aestivum) growth and soil ...

Demo 25-03 Thermionic Emission

open access: yes, 2001
Electrons may be emitted from a hot filament through a process known as thermionic emission. The electrons are "boiled" off the surface and accelerated by a screen that is at a positive potential with respect to the hot filament.

Drift‐Diffusion Models with Schottky Contacts at Metal–Semiconductor Interfaces

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT The paper deals with a drift‐diffusion model for semiconductor devices with Schottky contacts at all metal–semiconductor interfaces. The presented analytical investigations permit Boltzmann as well as Fermi–Dirac statistics for the charge‐carrier densities.

Cerium‐Modified TiO2 Nanomaterials Derived From Upcycled Coffee Ground Waste for Photocatalytic Oxidation and Hydrogen Production via Photoreforming

open access: yesChemistryOpen, Volume 15, Issue 10, October 2026.
Spent coffee grounds were valorized as a sustainable template for the solvent‐free synthesis of Ce‐loaded TiO2 photocatalysts, promoting enhanced Ce–Ti interactions and tailored morphology. The resulting materials were successfully applied in photocatalytic hydrogen production via ethanol photoreforming, gas‐phase 2‐propanol oxidation, and aqueous 5 ...

Almond Shell‐Derived Cellulosic Microfibres: Extraction, Characterisation and Applications in Sustainable Paper‐Based Packaging

open access: yesPackaging Technology and Science, Volume 39, Issue 10, Page 1231-1251, October 2026.
Cellulosic microfibres were extracted from almond shells using organosolv, soda and kraft processes, and comprehensive physicochemical, surface, thermal and morphological characterisation demonstrated their strong potential as sustainable fillers for paper‐based packaging application. ABSTRACT This study develops pathways for the valorisation of almond
