Summary: Conversion of a regular metal surface to a superhydrophobic one using laser processing shows great potential for applications such as anti-fouling, anti-corrosion, and anti-icing. This study demonstrates a facile laser technique that can convert the wetting behavior of aluminum surface from hydrophilic to hydrophobic and superhydrophobic with single-shot nanosecond laser irradiation. This technique offers a fast and scalable method to produce laser-induced surface superhydrophobicity.

Summary: This study investigates the heating of gold and gold-zinc oxide nanocrystals in a metal-organic framework using nanosecond laser pulses. The irradiation of Au@ZIF-8 composite particles results in the heating of the gold core and decomposition of the surrounding matrix. The study also shows that the surrounding material can be heated to a distance equivalent to the decomposition of ZIF-8.

Summary: The study investigates a method for slicing GaN single crystal substrate by controlling laser pulse energy and changing the distance between each laser shot. The results show that different types of cracking occur depending on the pulse energy and shot pitch, and controlling them is crucial for achieving smooth GaN substrate slicing. SEM images indicate that crack propagation can be controlled with respect to the irradiation plane at suitable pulse energy and distance.

Summary: The synthesis of two polymorphs of the spin crossover coordination polymer {[Fe(Htrz)2(trz)](BF4)}n is explored using novel template-free methods. A one-pot synthesis approach and the addition of ultrasound pulses are used to control the local synthetic conditions and improve the phase purity of the product. These approaches lead to a significant reduction in particle size and the transition from a mixture of polymorphs to a pure phase, without the need for surfactants.

Summary: Transition metal nitroprussides form a family of coordination polymers with interesting physical properties, and the use of different organic molecules as ligands can result in materials with different structures and spin-crossover behaviors, such as thermal hysteresis and reversible volume changes. The pillared ferrous nitroprusside obtained using a bidentate molecule, pyrazine, shows a 3D framework and exhibits thermally induced spin transition behavior, along with notable color changes. The reversibility of this thermally activated spin transition has been confirmed through various characterization techniques, making it a novel finding in the study of Fe(pyrazine)[Fe(CN)(5)NO] materials.

Summary: The THz conductivity of large area MoS2 and MoSe2 monolayers and their vertical heterostructure, MoSe2MoS2, was measured in the 0.3-5 THz frequency range. The ultrafast THz reflectivity of the MoSe2MoS2 heterobilayer is greatly enhanced when optically excited above the direct band gap energies of the constituting monolayers, with free carriers evolving with characteristic times found in each monolayer. Surprisingly, a similar enhancement is observed in the ultrafast THz reflectivity of the heterobilayer when excited below the bandgap energy of MoS2, with a proposed mechanism to explain these observations.

Summary: This paper presents a chemical strategy for obtaining nanoparticles of the RbxMn[Fe(CN)(6)]((x+2)/3)center dot nH(2)O (RbMnFe) Prussian blue analogue in a direct manner, aiming to maintain its switching ability at the nanoscale. The study found that smaller particles had lower rubidium content, potentially affecting the observation of switching properties on very small particles. The results show the potential for creating switchable particles without surfactants, and the importance of this work in processing nanoparticles into devices.

Summary: This study reports the THz transmission and reflection properties of an ultrafast optically excited highly resistive silicon wafer. By using amplified femtosecond laser pulses, the carrier density on the front surface of the wafer was modified, leading to changes in its dielectric properties at THz frequencies. The experimental results and analytical model demonstrate the feasibility of converting a silicon wafer into an ultrafast, tunable, and broadband neutral density filter or reflector in the THz frequency range.

Summary: The complexes of He, Ne, Ar, Kr, and Xe with B3N3H6 were investigated using MP2, CCSD(T), and SAPT ab initio methods. The complexes can be described as mono-, di-, and tri-coordinated to the N atoms, with stability following the order N-mono < N-di < N-tri. The interactions are dominated by dispersion and the binding energies are within the range of 1 or 2 kcal mol(-1). The results were compared with a recent DFT study on larger BN sheets complexes [Phys. Chem. Chem. Phys. 24 (2022) 2554-2566.].

Summary: It has been found that the introduction of buffer layers improves the electrical performance of solid oxide fuel cells (SSOFCs). In this study, varying ratios of Gd-doped CeO2 were used as buffer layers in YSZ-based SSOFCs. The results demonstrate that the performance of SSOFCs is enhanced when a buffer layer is added, with the highest performance achieved using Ce0.8Gd0.2O2-delta (GDC20) as the buffer layer. This suggests that the use of GDC series buffer layers is an attractive strategy to optimize performance loss due to electrolyte-electrode interactions.

Summary: This study investigates the influence of aspect ratio and quantum confinement on the single-photon and two-photon absorption cross-section of perovskite CsPbI3 nanorods. Experimental data shows that CsPbI3 nanorods have an extremely high two-photon absorption cross-section, significantly surpassing organic chromophores and other CsPbBr3 nanocrystals. Moreover, adjusting the aspect ratio can significantly enhance the absorption ability. Additionally, the study also reveals a moderate quantum confinement effect on the single-photon and two-photon absorption cross-section of the nanorods.
