Summary: To mitigate the adverse effects of molten corium after a reactor pressure vessel failure, new reactor designs incorporate a core catcher and sacrificial material to stabilize the corium. Existing reactors can be modified to allow injectable cooling materials. A novel granular carbonate mineral is proposed as a sacrificial material, which can quickly solidify the corium through thermal decomposition reaction.

Summary: In this work, elevated thermal and isothermal experiments of azobenzene were conducted using SENSYS Evolution DSC. Kinetic parameters and decomposition mechanism were determined using Kinetic Calculation (KC) method and Molecular Dynamics Simulation (MDS) method. The results demonstrate that azobenzene exhibits a distinct first endothermic and subsequent exothermic behavior during thermal decomposition. The apparent activation energy remains relatively constant in the range of 0.1 <_ alpha <_ 0.4 and gradually decreases as the reaction proceeds. The thermal decomposition behavior of azobenzene can be described by the Sestak-Berggren mechanism. At the initial stage, the decomposition process is controlled by the lack of sufficient free radicals, while at the autocatalytic stage, it is governed by the exponential growth of free radicals. Based on the Semenov model, the self-accelerating decomposition temperature (SADT) of azobenzene is calculated to be 380.5 degrees Celsius when packed in a 25 kg standard package.

Summary: The study found that FeCl3 and AlCl3 promote NC decomposition, while CuCl2 and ZnCl2 inhibit it. Trivalent metal chlorides increase the explosion risk in NC, while divalent metal chlorides act as inhibitors. The addition of metal chlorides can either promote or inhibit NC decomposition without changing its reaction mechanism. This research provides important information for enhancing the safety of NC storage, transportation, and usage.

Summary: Nonthermal plasma activation of light alkanes is a promising decarbonization strategy, but the growth of carbon on catalysts and electrodes is a limitation. This study provides visual evidence of nonuniform diamond-like carbon microstructures formed in a coaxial dielectric barrier discharge reactor. The spacing of the microstructures can be controlled by adjusting the applied voltage or burning voltage of the plasma.

Summary: Dual-layer photolithography (DLPL) is introduced as a derivative of conventional photolithography for nanoscale patterning, based on controlled exposure and development of overlapping positive and negative photoresists. By adjusting lithography parameters and material deposition, feature sizes, shapes, line widths, and materials can be independently controlled. This strategy is not limited to ultraviolet photolithography and can enhance the resolution of other energetic beam-based lithographic approaches.

Summary: This study presents a facile method for fabricating high-quality triangular micro-wires (TMWs) of organic-inorganic hybrid perovskite. The TMWs are grown on a Si/SiO2 substrate with triangular micro-trenches (TMTs) through blade coating. The resulting TMWs exhibit high crystallinity, and the size and periodicity of the TMTs array can be independently controlled. Photodetectors made from these TMWs demonstrate excellent responsivity and specific detectivity, with stable and reproducible photoresponse to pulsed light. The TMWs array holds potential for large-area, high-performance integrated optoelectronics, as shown in the demonstration of an image sensor application.

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.
