SORPTION OF DEUTERIUM OXIDE BY CELLULOSE
, 1936 The sorption of deuterium oxide by cellulose at 23.4 °C. was investigated over the whole range of vapor pressures and found to show the same characteristics as that of water.

In-situ water signal calibration method for thermal desorption spectroscopy
Nuclear Materials and EnergyA method is presented that allows to quantify water desorption in a thermal desorption spectroscopy (TDS) setup in-situ. It is based on deuterium (D) desorption from D-containing tungsten covered with a thin, electro-chemically grown tungsten oxide layer.

Metal-oxide-silicon diodes on deuterium-implanted silicon substrate
, 2000 Ion implantation was used to incorporate deuterium at the Si-SiO2 interface. Polycrystalline silicon gate metal-oxide-semiconductor diodes with 4 nm oxide grown on deuterium-implanted p-type (100) silicon substrate were investigated. It was observed that

The impact of deuterium oxide on the properties of resorcinol-formaldehyde gels [PDF]
, 2018 Resorcinol-formaldehyde gels offer a range of properties that can be exploited in a variety of applications, but better understanding of gel formation mechanisms is needed to enable rational control and optimisation of the physico-chemical ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Deuterium retention in tungsten oxide: the role of oxide damage
Nuclear FusionTungsten (W) is a common plasma-facing material in nuclear fusion devices. It readily oxidizes in the presence of oxygen, forming tungsten oxides, particularly WO _3 , which may modify deuterium retention.

Tuning Separator Chemistry: Improving Zn Anode Compatibility via Functionalized Chitin Nanofibers
Advanced Functional Materials, EarlyView.Nanochitin derived from waste shrimp shells is used to fabricate separators for aqueous zinc batteries. By tuning the density of amine and carboxylic surface groups, water mobility at the separator interface is controlled, promoting uniform zinc deposition, suppressing dendrite growth, and enabling exceptional cycling stability exceeding 2000 h ...
