This study investigates laser‐based oxide removal of Cu inserts in oxygen‐free conditions and examines long‐term oxidation kinetics and surface chemistry under different atmospheres via X‐ray photoelectron spectroscopy. Al–Cu compound casting with differently oxidized surfaces is performed, and intermetallic phase formation, morphology, and thermal ...

A theoretical and experimental spectroscopy study on methanol and ethanol conversion over H-SAPO-34 [PDF]
The elucidation of the structure-activity relation of zeolites or zeotype materials remains very challenging. Recent advances in both theoretical and experimental techniques provide new opportunities to study these complex materials and any catalytic ...

Synthesis and Characterization of CuO/graphene oxide composite [PDF]
Copper oxide and graphene oxide composite have been prepared successfully. The prepared composite have been characterized by XRD, SEM and UV-Vis. Band gap calculation using formula Eg= hʋ from UV-Vis shows a decrease in band gap. The electrical transport

Cathodic Cage Plasma Deposition of Nanostructured Cu–Fe–Se Coatings on Poly(methyl Methacrylate)
Nanostructured Cu–Fe–Se coatings are deposited on PMMA by a modified cathodic cage plasma process, enabling low‐temperature deposition on polymer substrates. A transition from discontinuous to compact morphology is observed with temperature, with optimal properties at 200°C, where improved CuFeSe2‐type bonding, lowest sheet resistance, and favorable ...

A rapid method for methanol quantification in spirits using UV-visible spectroscopy and FTIR [PDF]
Although standards methods of food safety assessment are important, these methods are relatively expensive and require intensive work and time. In alcohol beverage industries, ultraviolet visible (UV-Vis) spectroscopy and Fourier transform infrared (FTIR)
