This thesis presents a new experimental setup for surface analysis studies, incorporating chemical information from infrared reflection absorption spectroscopy (IRAS) and quantitative information from quartz crystal microbalance (QCM). The integrated IRAS/QCM surface analysis system enables in situ studies to be conducted of the metal/atmosphere interaction on a sub-monolayer level. In combinat...

Ammonia is critical to the world economy. However, nowadays production of ammonia exclusively carried out by well-known Haber–Bosch process, which an energy-intensive process that leads a large amount CO2 emissions. The search for alternative routes mandatory sustainable and zero emissions future Electrochemical nitrate-to-ammonia conversion emerges as suitable achieve decentralized at small sc...

Purpose Nitric oxide (NO) has gained attention for its role in facilitating wound healing by promoting cell migration, while being cytoprotective in a variety of cell types. We determined the efficacy of NO, administered using a novel application of copper-chitosan treatments (Cu-Ch), in facilitating corneal epithelial wound healing using an in vitro model of corneal epithelial and limbal epith...

This work aimed to characterize beverage wastewater generated in the industry and assess treatment plant performance by fungi (Penicillium sp.) feasibility of reuse. Freshly discharged was collected analyzed for physicochemical parameters such as Biological Oxygen Demand (BOD), Chemical (COD), Total Dissolved Solid (TDS), Nitrate, Phosphate, Magnesium, Calcium, Iron, Copper, Zinc standard metho...

Transparent MgAl2O4 ceramics were fabricated by pulsed electric current sintering (PECS) employing two-step mode. First, nanoscale powders produced solution combustion synthesis from hydrated nitrate compounds and urea. Subsequently, the synthesized sintered PECS with a heating rate of 100oC/min under an applied pressure 100 MPa. The process was conducted according to profile. At first step, te...

Monocationic gold(III) complexes with histidine-containing peptides, glycyl-L-histidine (Gly-L-His) and L-alanyl-L-histidine (L-Ala-L-His) have been synthesized and characterized by (1)H NMR spectroscopy and X-ray crystallography. The crystallized Au(III) complexes, [Au(Gly-L-His-N,N',N'')Cl]NO(3)·1.25H(2)O and [Au(L-Ala-L-His-N,N',N'')Cl]NO(3)·2.5H(2)O, were obtained from water solution at pH ...
