Ulexite/HDPE-BiO/HDPE layered composites for neutron and gamma radiation shielding.

In this study, 5, 10, and 15 wt% ulexite (NaCaBO(ΟH)·5HO, hydrated sodium calcium borate hydroxide) and 15 wt %BiO filled high density polyethylene (HDPE) composite materials were fabricated through conventional melt-extrusion processing techniques in the form of a layered structure in order to absorb both neutron radiations and the secondary radiations resulting from neutron induced reactions. In the layered structure, HDPE was used to slow down neutrons, while ulexite and BiO were used to capture thermal neutrons and secondary gamma radiations, respectively. The properties of ulexite/HDPE and BiO/HDPE composites were investigated through scanning electron microscopy (SEM), X-ray diffraction (XRD), thermogravimetric analysis (TGA).

In search of the bottlenecks of ammonia synthesis over Ru/Vulcan under ambient conditions.

Hydrogenation of the N-N bond under ambient conditions over 1 wt% Ru/Vulcan was monitored through Diffuse Reflectance Infrared Spectroscopy (DRIFTS) and DFT. IR signals centered at 3017 cm and 1302 cm were visible with attributes similar to the asymmetric stretching and bending vibrations of gas phase ammonia at 3381 cm and 1650 cm. The intensities of the signals increased with consecutive H : Ar and N flow cycles at room temperature and atmospheric pressure due to accumulation of the formed NH on the catalyst surface.

The effect of H : N ratio on the NH synthesis rate and on process economics over the CoMoN catalyst.

In this study, the process economics of ammonia synthesis over CoMoN was investigated by searching for an optimum feed stoichiometry. From ammonia synthesis rate measurements at atmospheric pressure and 400 °C over CoMoN, it was found that the rate was independent of H : N stoichiometry for stoichiometries above 0.5 : 1.

The effects of ozone on the acute phase of intestinal ischemia-reperfusion injury in rats.

Hydrogen sulphide partly involves in thiamine-induced tolerance to cadmium toxicity in strawberry (Fragaria x ananassa Duch) plants.

Although thiamine (THI) and hydrogen sulphide (HS) both have widely been tested in the plant under stress conditions, cross talk between THI and HS in the acquisition of cadmium (Cd) stress tolerance needs to be studied. So, an experiment was designed to study the participation of endogenous HS in THI-induced tolerance to Cd stress in strawberry plants. A foliar spray solution containing THI (50 mg L) was sprayed once a week for 4 weeks to the foliage of strawberry plants under Cd stress (1.
