A high‐surface‐area PtSn electrocatalyst supported on carbon was prepared by using a formic acid reduction method. The catalyst was characterized by X‐ray fluorescence, X‐ray diffraction, X‐ray photoelectron spectroscopy, and transmission electron microscopy. The electrochemical properties of the electrocatalyst were investigated by using polarization measurements, cyclic voltammetry, potentiostatic durability tests, and electrochemical impedance spectroscopy. An endurance test of 220 h at 0.4 V with recirculation of ethanol was carried out. Under continuous operation in a direct ethanol fuel cell, the electrocatalytic system shows an initial decay, but suitable stability is observed after about 100 h.

Single crystals of 8-hydroxy-5-nitroquinolinium p-toluene sulfonate (HNT) were grown by the slow evaporation solution growth technique. The structure was elucidated by single crystal X-ray diffraction analysis and the crystal belongs to the monoclinic system with the space group C2/c. The crystallinity of HNT was studied by powder X-ray diffraction analysis. The presence of functional groups was determined by FT-IR spectral analysis. The band gap energy is estimated by the application of the Kubelka-Munk algorithm. The charge transfer characteristic of the compound was studied by frontier molecular orbitals (FMOs) analysis. The rst-order hyperpolarizability of the HNT molecule was found to be 285.45 × 10 − 30 esu, which is ~ 750 times higher compared to the reference urea molecule. Investigation of the intermolecular interactions and crystal studies packing via Hirshfeld surface analysis, based on single-crystal XRD, reveals that the close contacts are associated with molecular interactions. Fingerprint plots of the Hirshfeld surfaces were used to locate and analyze the percentage of hydrogenbonding interactions. The Mulliken charge of the present molecule was theoretically analyzed. The Kurtz-Perry powder technique has been used to estimate the second harmonic generation. Observed small SHG and large hyperpolarizability are rationalized.

The heptanuclear cobalt cluster [Co7(emmp)6(CH3O)6]·(ClO4)2 (1) (Hemmp = 2‐ethyliminomethyl‐6‐methoxy‐phenol) was synthesized by the microwave‐assisted reaction of Co(ClO4)2·6H2O with 3‐ethoxy‐2‐hydroxy‐benzaldehyde (Hehb) and ethylamine in mixed solvent (acetonitrile:methanol = 1:1). Complex 1 was characterized by IR spectroscopy, elemental analysis, and X‐ray single‐crystal diffraction. The magnetic properties of 1 are discussed. Complex 1 displays dominant ferromagnetic interactions from the nature of the binding modes through μ3‐OCH3 and μ2‐phenoxo.
