Sacrificial‐Layer‐Assisted Heat‐Affected‐Zone Suppression in Laser Patterning of PET for High‐Performance Flexible Devices

Advanced Functional Materials, Volume 36, Issue 89, 5 November 2026.
A removable sacrificial polymer layer engineers the thermal boundary condition during nanosecond laser ablation of PET, suppressing heat‐affected‐zone formation without relying on costly ultrafast lasers. This strategy enables deep, high‐aspect‐ratio trenches with no detectable heat‐affected zone, templating silver‐filled mesh electrodes with record ...

Toward Pore‐Engineered 3D‐Printed Materials for Sorption Water Harvesting, Interfacial Evaporation, and Radiative Cooling

Advanced Materials, Volume 38, Issue 61, 2 November 2026.
Water harvesting, radiative cooling, and interfacial solar evaporation are fundamentally governed by coupled heat, mass, and light transport processes. These processes are mediated by pore architecture, including pore size, connectivity, and hierarchical organization.

IA method for measuring the amount of hoar frost formation in the recuperation channels of ventilation systems using the adjustable mathematical model of this process

MATEC Web of Conferences, 2017
The paper presents a method for measuring the amount of hoar frost formation in the recuperation channels of ventilation systems using the adjustable mathematical model of the hoar frost process. The principle is based on the fact that the contour of the

Hydrogen‐Bond Enabled Phosphite Based Intrinsic Flame‐Retardant Solid‐Solid Phase Change Materials Using Catalyst/Solvent‐Free Multi‐Component Reaction for Battery Thermal Management

Advanced Science, Volume 13, Issue 61, 3 November 2026.
The phosphite group endows intrinsic flame retardancy, while the P = O bond enhances intermolecular interactions to realize solid‐solid phase transition. Battery thermal management tests show the materials extend the safe working time of lithium‐ion batteries by 200%. Cone calorimeter tests indicate a 14s delay in ignition time, and reductions of 37.6%,

Defrost Cycle Optimization for Fan-Supplied Tube-Fin Evaporators Subjected to Frosting Conditions [PDF]

, 2018
Frost accretion on a tube-fin evaporator surface raises its thermal and hydraulic resistances, which in turn deteriorates the cooling capacity of the refrigeration system.

A Protocol for Lab‐Scale Production of 13C‐Labeled Yeast Extract as Internal Standard for Metabolomics and Quantification of Intracellular Metabolites

Current Protocols, Volume 6, Issue 11, November 2026.
Abstract Metabolomics enables the profiling of small‐molecule metabolites, thereby capturing the biochemical state of a living organism at a given moment and making it possible to monitor the organism's cellular responses to stimuli. This technique has become a powerful tool in pharmaceutical research, the food industry, and microbial research ...
