NOx Scrubbing Solution Boosts Safety, Efficiency
Unlike typical nitrogen oxide sulfide/caustic control chemistry, Bionomic Industries’ low-toxicity BioNOxSolver scrubbing solution is formulated so that it will not liberate flammable and dangerous hydrogen sulfide gas at pH-use conditions.

Electroless Nickel Coatings: Appearance, Gloss and Surface Morphology
For decorative coatings, appearance is the essential purpose for application, but also for functional surface finishes it becomes increasingly relevant as an added value on top of specified technical requirements. Appearance is affected by spectrum and intensity of incident light, roughness and morphology of the coating surface, optical properties of the coating material, eventual superficial oxide films, and individual perception. The predominant factor is surface roughness, which in turn depends on base material roughness, quality of substrate pretreatment, and nucleation and growth kinetics of the electroless nickel (EN) deposit. Interdependency of gloss measurements with roughness measurements and with chemical composition of coatings was investigated for new generation mid-P EN processes and compared to traditional ones.

Nanostructures by Anodization of Alumina in Phosphoric Acid at Low Potential
Anodic aluminum oxide (AAO) has been investigated, in terms of influence of the process time, anodizing potential and methanol addition on the structural features of porous anodic alumina formed in 0.1M H3PO4 solution by two-step self-organized anodizing for potentials ranging from 100-150 V. The structural features of the porous structures, including pore diameter and interpore distance, were evaluated from FE-SEM top-view images for samples anodized in the presence and absence of methanol.
