In this review, we demonstrate recent breakthroughs related to elucidating the nature of active sites using a variety of physicochemical methodologies and describe the substantial progress in engineering nanostructured metal-nitrogen-carbon (M-N/C, M=Fe, Co, etc.) catalysts by employing diverse precursors and synthetic strategies, which may offer some perspective for developing advanced electrocatalysts for the oxygen reduction reaction.

This review focuses on the interface tailoring of lead-halide perovskite solar cells, including the modification of each layer of the cell structure (i.e., perovskite absorber, electron-transport layers, and hole-transport layers) and the interfacial materials that can be introduced into the cell.

Three phase bottom-up growth is utilized to incorporate and engineer imperfections such as crystal defects and impurities in semiconductor Ge nanowires via catalyst and/or interfacial manipulation. High density of twin boundaries and above equilibrium amount of Sn in Ge enhance the functionality of the nanowires.

Memristors based on inorganic halide perovskite are fabricated for the first time. Their device stability and performance are improved greatly via ZnO capping within the device to modify the contact of the perovskite layer with the electrode, prevent reactions at the interface between the perovskite and electrode due to moisture, and completely change the conductive mechanism, thus improving the performance in all aspects. The proposed design and fabrication procedures endow the device with electro- and photo-reading functions, as well as advantages of solution and room-temperature processability for flexible devices.

The intrinsic optical quality of chemical vapor deposition (CVD) grown MoS2 is evaluated using the defect-induced PL emission spectra as well as the photoluminescence (PL) intensity ratio, obtained from measurements in air and vacuum. A correlation between electrical and optical properties in terms of mobility and defect-related PL intensity is also established.
