Reducing Water Activity by Zeolite Molecular Sieve Membrane for Long‐Life Rechargeable Zinc Battery

Advances in Materials, 2021
Aqueous electrolytes offer major advantages in safe battery operation, green economy, and low production cost for advanced battery technology. However, strong water activity in aqueous electrolytes provokes a hydrogen evolution reaction and parasitic ...

Relationship between the gas hydrate suppression temperature and water activity in the presence of thermodynamic hydrate inhibitor

, 2020
Hydrate formation and blockage in deepwater oil and gas operations can be prevented by using thermodynamic hydrate inhibitors (THIs). The presence of THIs changes the hydrate suppression temperature; therefore, predicting the change in the hydrate ...

Aflatoxin B1 (AFB1) production by Aspergillus flavus and Aspergillus parasiticus on ground Nyjer seeds: The effect of water activity and temperature.

Journal of food microbiology, 2019
Nyjer oil seed cake supports high levels of aflatoxin B1 (AFB1) production. AFB1 is a secondary metabolite of Aspergillus flavus and A. parasiticus, classified as a Class 1A carcinogen.

Water activity, not moisture content, explains the influence of water on powder flowability

LWT, 2019
. The effect of water content on the flow factor of pectin powder was investigated. Water content was expressed either as water activity or as moisture content.

Comprehensively active condensed water from vapors of plasmon-activated water

Chemical Engineering Journal, 2021
Abstract Water is the most environmentally friendly solvent, but bulk water is conventionally considered to be a bystander in reactions performed in it. For decades, scientists have been discussing the characteristics of water that differ from bulk water in special environments.

ACTIVE RENAL WATER EXCRETION

The Lancet, 1967
Abstract Water-loading experiments on normal young adults support the view that active water excretion by the kidneys helps to maintain the constancy of extracellular osmolality.

Water activity and pseudo-activity coefficient of sorbed water

Journal of Food Engineering, 1990
Abstract The sorption isotherm can be represented by a plot of the logarithm of a pseudo-activity coefficient log f′ = loga w − log W against W, the weight of water per 100 g of dried substance. This plot demonstrates the polyphasic behaviour of the system. With reference to the curve for a w = 1, the chemical potentials Δμ Φ for the first

Water Activation for Boosting Electrochemiluminescence

Angewandte Chemie International Edition, 2023
AbstractIn conventional luminol electrochemiluminescence (ECL) systems, hydrogen peroxide and dissolved oxygen are employed as typical co‐reactants to produce reactive oxygen species (ROS) for efficient ECL emission. However, the self‐decomposition of hydrogen peroxide and limited solubility of oxygen in water inevitably restrict the detection accuracy

Water Activity of Mammalian Tissues

Nature, 1958
SINCE the original report by Sabbatani1 that the freezing-point depression of various dog tissues is on the average 150 per cent greater than that of blood, there has been continued interest in the possibility that intracellular fluid is hypertonic to extracellular fluid.
