Summary: This study investigates the use of pi-conjugated small molecule N, N'-bis(naphthalen-1-yl)-N, N'-bis(phenyl)benzidine (NPB) as a hole transport layer (HTL) in poly(9-vinylcarbazole) (PVK) for inverted perovskite solar cells (PSCs). The doping of NPB leads to improved perovskite crystal growth, resulting in larger grain size and reduced defect density. The enhanced V-OC, J(SC), and FF of the PSC are attributed to the reduced surface roughness and improved hydrophilicity of the HTL.

Summary: Perovskite solar cells (PSCs) based on carbon have shown promise in photovoltaic applications due to their low cost, high stability, and good conductivity. By synthesizing metal oxide nanoparticles (Fe2O3-NPs and NiO-NPs) and doping them into carbon paste as a hole-transporting material (HTM), the performance of PSCs was improved. The device with Fe2O3-NiO@C as the HTM achieved a power conversion efficiency (PCE) of 13.27%, higher than the control device (9.49%), and exhibited excellent long-term stability. Hence, PSCs based on Fe2O3-NiO doped carbon have substantial PCE and potential for commercialization.

Summary: Potassium ion-based dual-graphite batteries (KDGBs) are a promising choice for large-scale applications due to their high voltage, low cost, and environmental friendliness. However, traditional KPF6/carbonate-based electrolytes have limitations such as oxidation decomposition, low concentration, and flammability, which affect the capacity and cyclability of KDGBs. In this study, a nonflammable potassium bis(fluorosulfonyl)imide/triethyl phosphate (KFSI/TEP) electrolyte was designed, which improved the performance of the KDGBs. The KDGBs using the 1:1.3 KFSI/TEP electrolyte showed enhanced capacity, excellent rate capability, and superior cyclability, providing feasibility for the development of long-life and safe-operation dual-graphite batteries.

Summary: Different amounts of B2O3 were added to Ce3+-doped Gd2O3-Al2O3-SiO2 glasses to enhance their photoluminescence and scintillation properties. The addition of Si3N4 effectively reduced Ce4+ to Ce3+ in the glasses. Increasing the B2O3 content resulted in a blue shift in the excitation and emission spectra. The photoluminescence quantum yield increased with B2O3 content, reaching a maximum of 59.55% at x = 15. The glasses exhibited good luminescent thermal stability and comparable X-ray excited luminescence intensity to Bi4Ge3O12 crystal.

Summary: Three series of Dy3+, Tb3+-doped and Tb3+/Dy3+ co-doped 40TeO2-20(Gd,Lu)2O3-40WO3 glasses were prepared successfully with a density of 6.75 g/cm3. The luminescence properties of these glasses were studied through transmittance, photoluminescence, time-resolved emission spectra, X-ray excited luminescence spectra, and luminescence decay curves. The optimal doping concentration of Dy3+ and Tb3+ ions in the glasses was determined under UV and X-ray excitation, respectively. It was found that there is efficient energy transfer from Dy3+ to Tb3+ ions in the photoluminescence spectra, but not under X-ray excitation due to complicated physical processes.

Summary: With the advancement of LED technology towards high-power, the heat generated by high power poses a significant challenge to the thermal decay and quenching of fluorescent materials in the LED device, leading to reduced luminous efficiency and lifespan. To overcome this issue, fluorescent materials with high thermal stability and improved heat dissipation have been prepared using boron nitride nanomaterials. By adjusting the ratio of boric acid to urea in the raw material, different structures of boron nitride nanoparticles and nanosheets were synthesized. The addition of these materials in PiG enhances mechanical strength, heat dissipation, and luminescent properties, resulting in higher quantum efficiency and improved heat dissipation in high-power LED.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
