Characterization of Volatile Organic Compounds and Warmed‐Over Flavor in Flat Peach Juice Through Thermal and Nonthermal Sterilization Using Integrated Flavoromics and Multivariate Analysis

open access: yesFood Science &Nutrition, Volume 14, Issue 4, April 2026.
Flat peach juice was subjected to thermal sterilization (high‐temperature sterilization and pasteurization) and nonthermal sterilization (high hydrostatic pressure and microwave sterilization). Volatile profiles and sensory attributes were characterized using HS–GC–IMS, HS–SPME–GC–MS, and bionic sensory evaluation.

Inflammatory Response‐Inspired Thermochromic Shield for Pneumatic Structures

open access: yesAdvanced Engineering Materials, Volume 28, Issue 6, 18 March 2026.
A thermochromic shield for pneumatic structures is developed, using anhydrous sodium acetate powder and thermochromic pigment‐included solution. In this shield composed of three layers, the exothermic and thermochromic reactions, followed by the mixture of both components, occur promptly with an incident of penetrating damage as a sign of initial ...

Development of a static feed water electrolysis system [PDF]

open access: yes
A one person level oxygen generation subsystem was developed and production of the one person oxygen metabolic requirements, 0.82 kg, per day was demonstrated without the need for condenser/separators or electrolyte pumps.

Early Mars volcanic sulfur storage in the cryosphere and formation of transient SO2-rich atmospheres during the Hesperian

open access: yes, 2016
In a previous paper (Chassefi\`ere et al., Icarus 223, 878-891, 2013), we have shown that most volcanic sulfur released to early Mars atmosphere could have been trapped in the cryosphere under the form of CO2-SO2 clathrates. Huge amounts of sulfur, up to

Liquid‐Phase Syngas‐To‐Methanol at Low Temperature: Mixed Alcohol Solvent‐Controlled Pathways for Circular Carbon Manufacturing

open access: yesChemSusChem, Volume 19, Issue 5, 13 March 2026.
Low‐temperature liquid‐phase methanol synthesis from syngas was demonstrated over CuO/ZnO/Al2O3 catalysts using mixed alcohol solvents. Solvent composition controls ester intermediate and methanol productivity. Methanol is a primary platform chemical for circular manufacturing.

Hydraulic calipers [PDF]

open access: yes, 1969
Hydraulic calipers determine area of annular openings in irregular or concealed passages. With modifications the device could be adapted to investigations of cross-sectional changes in heat flow passages, ducts, conduits, and heat exchanger ...

Study on the Equivalent Density Tool and Depressurization Mechanism of Suction-Type Depressurization Cycle

open access: yes
In order to further control the equivalent circulating density,a new type of annular pres-sure-reducing downhole tool for high temperature and high pressure wells-liquid-absorbing ECD tool is designed.Through this tool,the bottom hole pressure of the equivalent circulating drilling fluid can be close to its hydrostatic pres-sure,therebyachieving a ...
