Summary: The distribution of nanostructures on micro-nano composited surfaces significantly affects the pool boiling heat transfer performance. Surfaces with nanostructures covering the top and bottom sides have the lowest wall superheat, while surfaces with nanostructures etched at the top corners or edges have higher heat transfer coefficients. Bubbles are mainly generated on the tops of micro-pin-fins, alleviating the blockage of capillary wicking channels in high heat flux regions. Moreover, the condensation effect of subcooled liquid on the bubbles generated at the tops of micro-pin-fins is stronger.

High aspect ratio b-axis-aligned fibrous red phosphorus nanoribbons were easily prepared through liquid exfoliation, demonstrating impressive p-type transport behavior with a high mobility. These results indicate the great potential of fibrous red phosphorus as a promising channel material and provide a solid foundation for further research on the intrinsic properties of quasi-one-dimensional van der Waals materials.

Summary: Inorganic metal halide perovskites have superior environmental stability compared to their organic-inorganic counterparts, making them more promising for practical applications. This study investigates the stability of an archetypical all-inorganic CsPbBr3 single crystal and its single-carrier devices under Co-60 gamma-ray irradiation. The results reveal that the performance of the hole-only device deteriorates more than the electron-only device under high irradiation doses, suggesting different influences of gamma-ray irradiation-induced defects on hole and electron transport behaviors in CsPbBr3 single-crystal devices.

Summary: Zero-dimensional Cs3Cu2I5 is a promising metal halide scintillator for gamma-ray detection due to its large Stokes shift, high photoluminescence quantum yields, non-toxic nature, and excellent energy spectrum resolution. The irradiation stability of Cs3Cu2I5 single crystals under 60Co gamma rays was explored with a maximum accumulated dose of 800 krad. The optical properties of Cs3Cu2I5 single crystals showed a dose-dependent change at low accumulated doses, but further increase in dose did not lead to more severe degradation and even slight performance recovery occurred. The irradiation-induced Cs+-related Frenkel defects were found to contribute to the performance degradation.

Summary: A facile and mild solvothermal strategy was developed to synthesize highly crystalline red phosphorus using 1,2-diaminopropane as a nucleophilic agent. The dissolution-crystallization mechanism induced by the diamine was proposed to explain the phase transition of phosphorus from amorphous red phosphorus to crystalline red phosphorus. The structure of the crystalline red phosphorus was assigned as Form II RP by X-ray diffraction and other morphological characterization methods.
