Summary: This study demonstrates a scalable and conformal deposition of copper iodide (CuI) thin films using atomic layer deposition (ALD). The two-step ALD process, involving deposition of CuO and subsequent conversion to CuI using HI vapor, results in phase-pure, uniform, and high-purity CuI films. The successful deposition of CuI on various substrates and its application in diode structures and perovskite solar cells suggests that the ALD-based approach offers a viable alternative for depositing transparent conductive p-type CuI thin films in complex high aspect ratio structures and large substrate areas.

Summary: This study reports the fabrication of potassium-incorporated transparent zinc oxide (K-ZnO) thin films by subjecting ZnO thin films to high-pressure molten-salt treatment (hp-MST) in potassium nitrate (KNO3), which successfully led to p-type semiconductor films. The change in oxygen vacancies and carrier type with increasing hp-MST temperature suggests successful potassium incorporation into the surface of the ZnO thin films. This study introduces a simple and efficient alternative strategy for homojunction semiconductors that can be used to prepare next-generation highly efficient semiconductor devices.

Summary: Void formation is an important aspect in the irradiation response of metals. In situ transmission electron microscopy was used to observe the evolution of voids during irradiation. By combining a convolutional neural network with greedy matching, a data-driven approach was utilized to detect and track nanovoid evolutions and migrations, revealing surprising phenomena of void size fluctuation and shrinkage in irradiated Cu with pre-existing nanovoids. Phase-field simulations provided insights into the fundamental mechanism behind the observed void size fluctuation phenomenon.

Summary: The role of Mg solute in facilitating the formation of growth twins in twinned Al-Mg alloys remains unclear. The twinned grain fraction increases with increasing film thickness until it reaches a peak at 120-160 nm. Al-Mg alloys show higher twinned grain fractions compared to pure Al. The increase in twin density is attributed to the impingement of twinned grains during island coalescence and their higher survival rate during grain growth.

Summary: CeO2 is a rare-earth refractory material that can be used to develop practical thin films for high temperature thermophotovoltaics (TPVs) and thermal barrier coatings (TBCs) due to its high refractive index, high thermal stability, and infrared transparency. This research provides new insights into the effects of temperature change on the electronic structure of CeO2, which is important for the aforementioned applications. Reflectance and transmittance measurements of CeO2 thin films were conducted using Fourier transform infrared (FTIR) spectroscopy at room temperature, and the results can be leveraged for TPV and TBC designs. Additionally, a simulation using the S4 software package showed strong agreement between experimental FTIR reflectance and simulated reflectance at different angles.

Summary: Oxide-dispersion-strengthened (ODS) alloys are being used in high temperature turbine, spacecraft, and nuclear reactor components due to their high temperature strength and radiation resistance. A process-synergistic approach using laser powder bed fusion (LPBF) is proposed to introduce oxide particles into ODS alloys. Microstructure analysis reveals the formation of nanoscale spherical mixed oxide particles and large agglomerates with internal cracks. Mechanical testing shows that cracking of agglomerate particles negatively affects the tensile ductility, suggesting a need for improved processing methods to promote the uniform dispersion of oxide particles during laser exposure.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
