Summary: Flip-chip bonding is a critical packaging technology that allows for the smallest possible form factor. This paper demonstrates the feasibility of using copper and nickel-gold surface finishes in a solder bumping, flip-chip bonding, and reflow process. By reducing native oxides and using copper formate, the copper surface is protected and solder wetting is achieved. The study also shows that bumping solder directly on copper pads using copper formate is a novel research contribution.

Summary: The aim of this study is to characterize the degradation products of lead weights from an important Steinway & sons piano. The results showed that hydrocerussite is the main degradation product on the superficial layer of lead weights, followed by lead acetate and formate. Exposure of lead weights to formic and acetic acid vapours promotes the formation of basic lead formate, which leads to the formation of hydrocerussite. These results can preserve the sound of the piano by limiting the degradation of its components.

Summary: This contribution presents a new efficient two-stage production route for green methanol from biomass. The hydrogenolysis step is focused on and a materials solution is proposed to solve the problem of catalyst corrosion caused by the acidic mixture formed in the previous biomass oxidation step. Cu0.9Al2O4 spinel materials are found to be effective catalysts with lower corrosion compared to commercial catalysts such as CuO/Cr2O3.

Summary: This study investigated the feasibility of producing XOS from corncob by using a tri-acid mixture of formic acid, acetic acid, and propionic acid (PA). A high yield of 69.1% was achieved under the optimal volume ratio of formic acid, PA, and acetic acid at 1:5:4, and a reaction temperature of 150 degrees C for 50 minutes. In summary, replacing 60% of PA with formic acid and acetic acid, and lowering the hydrolysis temperature from 170 degrees C to 150 degrees C were important for reducing the cost of XOS production using organic acid hydrolysis.

Summary: This study aimed to investigate the effect of FocA on intracellular and extracellular formate levels by altering FocA levels, mutating the chromosomal focA gene, or introducing additional copies of focA. The results showed that the expression of the native focA-pflB operon ensures relatively constant intracellular formate levels during exponential phase growth, and enhancing focA expression leads to higher formate excretion from the cell. Furthermore, chromosomal focA mutations that altered formate concentration inside the cell caused a negative fermentative growth phenotype, indicating the role of FocA in regulating intracellular formate levels.

Summary: This study utilizes an engineered enzymatic catalyst in a batch reactor to convert CO2 into formic acid (as formate). By adjusting the operating voltage, implementing an O2 scavenger, and controlling system pH, both formate production and Coulombic efficiency can be maximized. The peak formate production and efficiency achieved in long-term experiments were 225 mM and 91%, respectively, showing the potential for effective CO2 conversion to formate.

Summary: This work presents studies on the photochemical transformations of TU and Cys with the addition of Cu(II) or Fe(III) ions. The results show that the oxidation rate of the thiols increases significantly when Cu(II) or Fe(III) ions are added to the system. It has also been found that TU and Cys can form stable complex compounds with the studied metal ions. The oxidation rates of the thiols are found to depend on the radiation intensity and emission spectrum of the irradiation sources.

Summary: The structure and electrochemical properties of zinc(II) complexes with a face-capping ligand have been investigated, revealing the effect of the ligand on bound semiquinonate (SQ) radicals. The substitution pattern of the SQ ring plays a crucial role in determining the fate of the bound SQ radicals. Additionally, the protective pocket formed by the ligand's phenyl substituents is unable to prevent decomposition of SQ radicals with minimal steric bulk, suggesting that substitution of the SQ ring is the main contributor to their stabilization.

Summary: In this article, the synthesis and characterization of copper, nickel, and palladium complexes bound by bidentate ligands derived from ortho-phenylenediamine are described. The complexes contain tunable H-bond donors and their crystal structures reveal intramolecular H-bonding interactions between the ligand scaffolds. Variations in the coordination sphere led to the isolation of the complexes in square-planar or twisted pseudo-tetrahedral geometries. Structural analysis showed that intramolecular H-bonding interactions can be altered by disrupting the bonds between countercations, solvent of crystallization, and ligand scaffold, resulting in changes in the geometry of the complexes. DFT calculations confirmed that Cu complexes prefer twisted geometries while Ni and Pd complexes favor square-planar geometries.
