Heterometallic Ge–O–Sn-Bridged Oxychalcogenides Sr3GeSnO4Q3 (Q = S, Se) with Wide Band Gaps and Moderate Infrared Nonlinear Optical Responses

Cihai Hong, Aoge Yao, Chunlan Tang, Zhihui Zhang et autres

Developing infrared (IR) nonlinear optical (NLO) materials that combine strong frequency-conversion capability with sufficiently wide band gaps remains a significant challenge. Herein, two new heterometallic oxychalcogenides, Sr3GeSnO4Q3 (Q = S, Se), were successfully designed and synthesized. Both compounds crystallize in the noncentrosymmetric …

Engineered Nonheme Iron Enzymes Enable Asymmetric Hydrogenation of Alkenes

Yunfei He, Shuang-Yu Dai, Mei‐Yan Xu, Baixu Ma et autres

Developing biocatalytic systems capable of reducing simple alkenes is highly desirable for synthetic chemistry and biosynthesis, yet existing enzymes remain largely restricted to their ability to convert polarized, electron-deficient substrates. Here, we present a nonheme iron metalloenzyme platform that enables hydrogenation of …

Oxygen‐Substitution Induced High‐Performance Nonlinear Optical Properties: Witnessed by the First Quaternary Oxythiostannate

Rui Xiao, Wen‐Dong Yao, Wenhao Xing, Jian Tang et autres

Abstract Oxychalcogenides can combine the large second‐harmonic generation (SHG) effects of chalcogenides with the wide bandgaps of oxides to obtain high‐performance infrared (IR) nonlinear optical (NLO) crystal materials. Here, the first quaternary oxythiostannate NLO crystal material Sr6Sn3OS11 crystallized in the trigonal noncentrosymmetric …

Partial congener substitution induced wide band gap witnessed in diamond-like chalcogenide ZnHg 2 P 2 S 8 and its second-order nonlinear optical properties

Chunlan Tang, Aoge Yao, Wenhao Xing, Jian Tang et autres

] motifs dominate the SHG effect, while the introduction of Zn enlarges the band gap. This work not only presents an exceptional IR NLO candidate overcoming the band gap-NLO efficiency paradox, but also establishes a general design strategy for developing high-performance IR …

Research Status of Plugging Materials for Oil and Gas Drilling

Boran Xing, Jiahui Ruan, Jian Tang

As oil and gas exploration and development continue to advance into deep formations and complex geological areas, the problem of lost circulation during drilling has become increasingly prominent. Lost circulation not only increases drilling costs and extends drilling cycles, but may also …
