Summary: Chemical thinning of germanium wafers was conducted in H3PO4:HNO3:HF aqueous solutions, adjusting etch rates and surface morphology through changes in etchant dilution and viscosity. Smooth and pitless surfaces were achieved at industrially acceptable rates via a diffusion-controlled mechanism. The use of etchant-resistant wax allowed reversible bonding to a polypropylene substrate, presenting a potential route for industrial production of thinned germanium optoelectronics.

Summary: Intercalation chemistry plays a crucial role in solid-state physics and chemistry, enabling the modulation of electronic structures and the construction of new materials with unique properties. It has gained popularity in recent years in the synthesis and regulation of 2D transition metal dichalcogenides (TMDs), which have extensive applications in electronics, optoelectronics, and energy-based devices. In this review, the authors provide a comprehensive overview of recent advances in intercalation exfoliation of 2D TMD materials, focusing on the interactions between the host, guest, and solvent. The effect of intercalation chemistry on the synthesis and modification of TMD nanosheets is discussed, considering lattice strain, interlayer distance, and carrier density. The review concludes with a prospectus on future research opportunities in the intercalation chemistry of 2D materials.

Summary: The long time scale associated with ligand residence times makes their computation challenging. The recently developed Gaussian mixture based enhanced sampling technique allows for the computation of residence times and enables an understanding of their unbinding mechanism. Guest unbinding often occurs through a series of intermediate states, which can be characterized by the number of water molecules in the binding cavity. In several cases, the residence time is correlated with water trapping times in the cavity.

Summary: This study reports a series of simple multi-guest/host organic long persistent luminescence (OLPL) materials with high quantum yield, achieved by doping phenothiazine derivative guest molecules into 9H-xanthen-9-one host matrices. The F-substituted phenothiazine derivative doping system exhibits highly efficient emission with a quantum yield of 46.3% in air. Moreover, these OLPL materials show promising potential for applications in the field of heat resistance due to their high luminescence efficiency at high temperatures.

Summary: The transient self-assembly of molecules under the direction of a consumable fuel source enables the preparation of bioinspired supramolecular hydrogels. Unlike traditional hydrogels that rely on thermodynamic equilibrium, these hydrogels are formed through transient physical crosslinking driven by the consumption of a reactive chemical fuel. The affinity and dynamics of CB[7]-guest recognition are altered by this fuel, allowing for control over the formation and properties of the hydrogels.

Summary: Nuclear magnetic resonance (NMR) lineshape analysis is a powerful tool for studying chemical kinetics. This article provides techniques for analyzing the relationship between experimentally observed spin kinetics and corresponding chemical kinetics. The advantages of using analytical solutions for lineshape analysis over numerical calculations are discussed. The article also discusses various aspects of exchange kinetics and introduces the concept of "reduced equivalent schemes" to simplify the analysis. Theoretical results are applied to the analysis of different systems in literature examples.

Summary: The low and weakly temperature-varying lattice thermal conductivity in crystals with a complex unit cell such as type-I clathrates is believed to be caused by the reduced momentum and energy space available for propagative lattice vibrations. Energy renormalization of low-lying optical branches due to anharmonic interactions has been shown to contribute to this anomalous behavior, which has been supported by inelastic neutron scattering studies on type-I clathrates.
