K3Sr3Li2Ga4B6O20F: A Sr2Be2B2O7-Type Ultraviolet Nonlinear Optical Crystal

Bing Li, Aoge Yao, Jianqiao Wang, Zhengyang Zhou et autres

A novel gallium-based nonlinear optical (NLO) crystal without the toxic Be element, K3Sr3Li2Ga4B6O20F, was successfully realized using a chemical substitution strategy from Sr2Be2B2O7 (SBBO), in which Sr2+ and Be2+ cations are cosubstituted by K+ and Sr2+ and Li+ and Ga3+, respectively. In …

Ba7Zn5Ga6O21: Terminal Oxygens Enable High Oxide-Ion and Proton Conductivity in a Condensed Three-Dimensional Tetrahedral Framework

Zien Cheng, Guangxiang Lu, Maxim Avdeev, Ying Wang et autres

Functional oxides exhibiting high oxide-ion and proton conductivity are crucial for advancing solid oxide fuel cells and related electrochemical technologies. Here, we demonstrate that terminal oxygens can endow the condensed three-dimensional (3D) tetrahedral framework with additional local structural flexibility and thus enable …

Unlocking a Chemically Fertile Moderate-Pressure Regime in High-Pressure Borate Synthesis Using Soft-Chemistry Precursors

Yunwei Zhao, Zien Cheng, Pengfei Jiang, Ting Bin Wen et autres

Borates exhibit exceptional structural diversity, yet high-pressure/high-temperature (HP/HT) synthesis has predominantly focused on increasingly extreme conditions, leaving moderate pressure–temperature regimes largely unexplored. Here, we demonstrate that this limitation is primarily kinetic rather than thermodynamic. By integrating sol–gel-derived, chemically homogeneous precursors with HP/HT …

An integrated single-cell, spatial, and bulk transcriptomic atlas of the immune response to Nocardia seriolae infection in largemouth bass (Micropterus salmoides)

Tao Liu, Zhengyang Zhou, Jin-Lai Gu, Zheng-Ran Jian et autres

Granulomas are evolutionarily conserved, macrophage-driven immune structures that form to wall off persistent pathogens, representing a core pathological hallmark in major human diseases like tuberculosis. The evolutionary origins of these complex structures are rooted in teleost fish, making them a critical model …

K(UO 2 )O 2 (H 2 O)Cl·2H 2 O: Identification of Uranyl Peroxide Chloride as a Studtite Derivative

Junyi Li, Jiali Chen, Xiang‐Long Li, Linmin Li et autres

Uranyl peroxide chemistry has traditionally been limited to natural phases─studtite and metastudtite─or to synthetic uranyl peroxide complexes and clusters in which the uranyl equatorial plane is generally oxygen-coordinated. Herein, we report the first uranyl peroxide chloride compound of K(UO 2 )O 2 …

Ag 2 Se Polymorphs: Structure Determination and Variations in Thermoelectric Properties

Binbin Liu, Mengjia Luo, Yuanhang Guo, Tao Fan et autres

The development of high-performance, flexible thermoelectric (TE) materials is essential for advancing self-powered wearable electronics. Among n -type candidates near room temperature, Ag 2 Se has attracted considerable interest, but its polymorphism─especially the poorly understood metastable phase─has hindered structure–property correlations and materials …

From Holodirected to Hemidirected Coordination Activated by Oxygenation Strategy: A Facile Route to Long Wave Infrared Birefringent Crystal

Xinyang Li, Xiyue Cheng, Chun‐Li Hu, Bingxuan Li et autres

Abstract Long wave infrared (LWIR) birefringent crystals are essential for infrared optical applications but such materials are rarely reported due to the requirements of large birefringence and wide infrared transmission range. This study proposes a facile route to create new LWIR birefringent …

Path optimization of cascaded prism scanning beam defined by the rotation prism coordinate system

Anhu Li, Yelin Liu, Zhengyang Zhou

Disordered multi-target scanning is an important application scenario of lidar target tracking technology. However, when dealing with scanning beam paths steered by cascaded prisms, it presents notable challenges, including highly non-linear and strongly coupled characteristics between the output vectors and prism rotation …

One-dimensional scintillator film with benign grain boundaries for high-resolution and fast x-ray imaging

Haodi Wu, Qian Wang, Ao Zhang, Guangda Niu et autres

Fast and high-resolution x-ray imaging demands scintillator films with negligible afterglow, high scintillation yield, and minimized cross-talk. However, grain boundaries (GBs) are abundant in polycrystalline scintillator film, and, for current inorganic scintillators, detrimental dangling bonds at GBs inevitably extend radioluminescence lifetime and …
