Solubility of water in hydrocarbons as a function of water activity
Talanta, 1968A method is described for determination of low solubilities of water in organic liquids (such as are used in solvent extraction) by vacuum distillation of a suitably sized equilibrated sample through magnesium perchlorate in a conventional weighing tube. Tritium tracer is used to estimate completeness of water absorption.

Comprehensively active condensed water from vapors of plasmon-activated water
Chemical Engineering Journal, 2021Abstract 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.

Water Activity of Mammalian Tissues
Nature, 1958SINCE 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.

Photooxidant activity in natural waters
Environmental Toxicology and Chemistry, 1985Abstract After exposure to sunlight or laboratory UV light, sterilized water samples (or their reconstituted concentrates) from California and Hawaii oxidized several common environmental contaminants, including ethylenethiourea, thiobencarb, DDE and aldrin, which do not absorb ultraviolet radiation appreciably in the sunlight wavelength

Antimicrobial activity of superoxidized water
Journal of Hospital Infection, 1996We tested the antimicrobial activity of superoxidized water against methicillin-sensitive Staphylococcus aureus, methicillin-resistant Staphylococcus aureus, Staphylococcus epidermidis, Serratia marcescens, Escherichia coli, Pseudomonas aeruginosa and Burkholderia cepacia. The number of bacteria was reduced below detection limit following incubation in

Active Thermochemical Tables: Water and Water Dimer
The Journal of Physical Chemistry A, 2013A new partition function for water dimer in the temperature range 200-500 K was developed by exploiting the equations of state for real water vapor, liquid water, and ice, and demonstrated to be significantly more accurate than any proposed so far in the literature.

Detecting water waste activities for water-efficient living
Proceedings of the 13th international conference on Ubiquitous computing, 2011Towards persuasive system for efficient use of water resource, we propose a method to detect "water waste" among water-related activities based on water sound analysis. We supposed two types of water-wastes: inter-activity water waste and intra-activity water waste.

The Intracellular Water Activity of Bacteria in Relation to the Water Activity of the Growth Medium
Journal of Applied Bacteriology, 1981Intracellular water activities ( a w ) calculated from the solute composition of various bacterial cells, are in good agreement with values derived from intracellular freezing point data.

Apparatus Determining Water Activity with Isopiestic Method and Measurement of Water Activity
Advanced Materials Research, 2014A new apparatus determining water activity using isopiestic method was developed. The water activities of the systems of LiCl−H2O, NaCl−H2O and KCl−H2O at 298.15 K were measured using isopiestic method. Compared with the literature, the results of measurement are in good agreement with the literature, and the apparatus reliability was verified.
