ABSTRACT This study successfully prepared a high‐palladium (Pd)‐loading (51 wt%) Pd/Al2O3 composite through multiple wet impregnation. The material exhibited excellent hydrogen isotope separation performance, with metal–support interactions endowing it with a higher plateau pressure and lower desorption temperature.

Laser‐Driven Halide Exchange and High‐Resolution Multicolor Patterning of Perovskite Films
ABSTRACT Translating the excellent properties of metal halide perovskites (MHPs) into practical flexible optoelectronic devices requires high‐resolution multicolor patterning techniques that are compatible with post‐fabrication processing. However, such a capability has remained elusive.

ABSTRACT Expanding near‐infrared (NIR) spectral response and utilizing ultraviolet (UV) photons are effective strategies for enhancing the power conversion efficiency (PCE) of lead halide perovskite solar cells (PSCs). However, the range of NIR spectral response extension and the utilization of UV light for devices are not enough, and the loss of ...

Melting Preparation for Tungsten‐Doped Graphene/Copper Composites
ABSTRACT Melting production plays a pivotal role in the modern copper industry. However, applying this process to fabricate nanocarbon (e.g., graphene, carbon nanotubes)‐reinforced copper matrix composites has remained a long‐standing challenge for nearly 2 decades.

由于空气湿度与大气压有关,在高原地区计算空气湿度时,如果仍用GB311—83和IEC标准中提供的湿度图读取湿度值,将带来不能允许的误差.本文介绍了准确计算空气湿度的公式组和一个修正公式,此修正公式附加于标准湿度图读数可以快速简便地得到准确的空气绝对湿度值.为了保证湿度测量的准确度,干球和湿球温度计的读数误差应分别控制在±0.5℃和±0.2℃以内.

Influences of Temperature and Humidity on the Residual Strength of Self-Hardening Mold after Heating at High Temperature [PDF]
Sand mold bonded with sodium silicate and dicalcium silicate has more merits than CO_2 sand mold. But CO_2 and mold bonded with sodium silicate has difficulty in collapsibility because of its too high residual strength after heating at high temperaturse.

ABSTRACT Water security in tropical regions faces escalating pressures from climate change, land‐use shifts, and population growth. We conducted a bibliometric review of 1146 peer‐reviewed articles (1964–2023) on tropical water security. Latent Dirichlet Allocation identified 13 thematic topics and their evolution. Publications rose sharply after 2012,

Influence of Temperature and Humidity on Characteristics of Self-Hardening Mold [PDF]
Until now many studies on the self-hardening mold by sodium silicate and calcium salt silicate have been researched from several points of vi-ew in many laboratories. The strengthening of this mold has been considered probably to depend upon the chemical
