Summary: Wearable devices can benefit from the use of stretchable conjugated polymers (CPs). Traditional design assumes that low elastic modulus (E) is crucial for achieving high stretchability, but this research challenges this notion. It is discovered that the degree of entanglement, rather than softness alone, determines stretchability. Even rigid CPs can exhibit high stretchability. Two model CPs with different elastic moduli are studied to further investigate mechanical behavior and deformation mechanisms. By challenging the conventional design metric of low E for high stretchability and highlighting the importance of entanglement, this research hopes to expand the range of CPs available for use in wearable devices.

Summary: This study demonstrates an in situ plasma pretreatment method for achieving ultrahigh-power and stable thin-film electrodes using sputtered iron oxysulfide (FeOxSy) thin films. The pretreated FeOxSy thin films exhibit a remarkably high power density and stable cycling performance, thanks to their high structural integrity, perfect electrochemical reversibility, and near-surface charge exchanges.

Summary: This study reports the realization of four different types of chalcogenide perovskite thin films with controlled phases through CS2 annealing. These films exhibit bandgaps and photoluminescence (PL) in the visible range. The variation in PL width across different compounds is attributed to the difference in kinetic barriers between local structural motifs. The findings highlight the potential of chalcogenide perovskite thin films for optoelectronic applications, while emphasizing the challenges in synthesis and performance optimization.

Summary: Pentacene deposited on silica adopts two different packing arrangements, with a kinetically favorable thin-film phase and a thermodynamically stable bulk phase. Research has shown that both phases co-nucleate at the interface, with the deposition process influenced by substrate temperature and thickness.

Summary: This article introduces a new technique, magneto-Archimedes levitation (MagLev), for estimating the density of hydrophobic polymer thin films, and validates its reliability in different thickness ranges. By comparing density measurements of various polymer films with their bulk values, apparent changes in film density were observed as thickness varied, providing a new approach for studying polymer films.

Summary: Antiferroelectric PbHfO3 thin films are grown using atomic layer deposition with Pb and Hf precursors at a substrate temperature of 250°C, exhibiting double hysteresis loops with high energy storage density but no clear evidence of an intermediate phase. Temperature-dependent studies reveal a phase transition at 185°C, likely to a paraelectric phase, highlighting the unique properties of thin film perovskite antiferroelectrics.

Summary: This study investigates the structural, mechanical, dynamical, and electronic properties of Fe2Mo6Se8 and Cu2Mo6Se8 seleno-Chevrel phases. The seleno-Chevrel phases exhibit antibacterial and antibiofilm activities against Staphylococcus aureus and Escherichia coli under infrared and white light illumination. Fe2Mo6Se8 demonstrates higher photocatalytic hydrogen evolution rate compared to Cu2Mo6Se8.

Summary: Chevrel Phases, MxMo6S8, are a class of heterogenous catalysts with unique combination of low-coordinate molybdenum atoms, tuneable oxidation state, thermal stability, and dual Lewis acidity & basicity, making them excellent candidates for fundamental catalytic reactions. Recent developments in synthesis techniques have lessened historical constraints, but the catalytic community has been slow to adopt these advances. This review summarises five decades of catalytic reports, identifies trends and gaps within the literature, and provides perspective on future directions for the catalytic application of Chevrel Phases.

Summary: This paper reviews a recent patterning technique called electrohydrodynamic patterning (EHDP), which uses an externally applied electric field to create micro-/nano-patterns on thin polymeric films. The theoretical and numerical studies of EHDP are presented, as well as the discussion on how the characteristic wavelength and time are influenced by external conditions and polymer properties. Various strategies for fabricating high-aspect-ratio or hierarchical patterns are reviewed, with emphasis on aligning and ordering of anisotropic polymers. The paper also provides a perspective on the novelty and limitations of EHDP compared to conventional patterning techniques, and suggests possible future research directions.

Summary: In this study, Tetrakis(dithiocarboxylato)molybdenum(iv) complexes were synthesized and characterized as precursors for the aerosol assisted chemical vapor deposition (AACVD) of MoS2 thin films. The thermal behavior of the complexes was suitable for AACVD, and MoS2 thin films were successfully grown using Mo(S2CMe)(4) as a precursor in toluene solution. The films exhibited a 2H-MoS2 structure with vertically oriented morphology and a thickness of 2.54 μm, which was confirmed by various characterization techniques including GIXRD, XPS, EDS, and FE-SEM. The Raman E-2g(1) and A(1g) vibrational modes of crystalline 2H-MoS2 were also observed.
