If a solution at A is cooled without loss of solvent along ABC, spontaneous nucleation cannot occur until C is reached. Although the tendency to nucleate increases once the labile zone is reached, some solutions become too viscous to permit nucleation and set to a glass. Supersaturation can ...
LeucoCrystal Violet(LCV) is a quick, simple and relatively safe method and has been popular for some time. In the presence of blood and hydrogen peroxide, colourless LCV is oxidized to purple Crystal Violet (also calledGentianviolet,Fig. 11). Crystal Violet exhibits weak fluorescence at 695nm...

The invention provides a crystal glass digestion method and a method for measuring lead content of crystal glass. The method comprises the following steps: adding crystal glass ground into powder into a polytetrafluoroethylene digestion tank, adding hydrofluoric acid, nitric acid and hydrogen peroxide,...
The photosynthesis of hydrogen peroxide in the presence of zinc oxide, cadmium sulphide or basic zinc carbonate, as a means of storing solar energy, is re-examined. It is shown that with due allowance for losses of incident energy by the processes of reflection and luminescence, a maximum quan...
Effect of the Second-Shell Coordination Environment on the Performance of P-Block Metal Single-Atom Catalysts for the Electrosynthesis of Hydrogen Peroxide Hydrogen peroxide (H2O2) is an important chemical with a diverse range of industrial applications in chemical synthesis and medical disinfection. The...
Titanium powder (5 mmol) was dissolved in a solution of hydrogen peroxide (30%, 20 ml) and ammonium hydroxide (28%, 5 ml). The titanium powder dissolved immediately, and then a yellow peroxo titanium complex formed. After 2 h, when the titanium metal had completely dissolved, a complexing...
Shown are a liquid crystal composition satisfying at least one of characteristics such as high maximum temperature, low minimum temperature, low viscosity, suitable optical anisotropy and large negative dielectric anisotropy, or having a suitable balance regarding at least two of the characteristics, and...
The polymerization initiator may be a known polymerization initiator, such as an azo polymerization initiator, an organic peroxide polymerization initiator, or a photopolymerization initiator. For example, the azo radical polymerization initiator may be azobisisobutyronitrile or azobiscyclohexanecarbonitrile. ...
