Erbium ions are commonly used to extend the photoelectric properties of metal halide perovskites from visible to near-infrared (NIR) range. However, achieving high-efficiency multi-mode luminescence in a single system is difficult due to the weak absorption associated with forbidden 4f-4f transitions. In this study, a unique strategy is proposed to...

Hydrometallurgy remains a major challenge to simplify its complex separation and precipitation processes for spent lithium-ion batteries (LIBs). Herein, we propose a Fischer-lactonisation-driven mechanism for the cascade reaction of leaching and chelation of spent LIBs. Citric acid undergoes a two-step dissociation of the carboxylic acid (-COOH) and...

The CRISPR/Cas system is a powerful genome editing tool and possesses widespread applications in molecular diagnostics, therapeutics and genetic engineering. But easy folding of the target sequences causes remarkable deterioration of the recognition and shear efficiency in the case of single Cas-CRISPR RNA (crRNA) duplex. Here, we develop a CRISPR/Cas...

The dinitrogen (N2) chemistry of lanthanides remains less developed compared to the d-block metals and lanthanide-promoted N2 functionalization chemistry in well-defined lanthanide complexes remains elusive. Here we report the synthesis and characterization (SQUID, EPR, DFT, X-Ray) of the siloxide supported heterobimetallic (Tm/K) complexes [{KTm(OSi(OtBu)3)3}2(μ-η2:η2-N2)]...

Deep learning tools for enzyme design are rapidly emerging, and there is a critical need to evaluate their effectiveness in engineering workflows. Here we show that the deep learning-based tool ProteinMPNN can be used to redesign Fe(II)/αKG superfamily enzymes for greater stability, solubility, and expression while retaining both native activity and...

Stabilizing specific intermediates to produce CH4 remains a main challenge in solar-driven CO2 reduction. Herein, g-C3N4 is modified with saturated and lacunary phosphotungstates (PWx, x = 12, 11, 9) to tailor the CO2 reduction pathway to yield CH4 in high selectivity. Increased lacuna of phosphotungstates leads to higher CH4 yield and selectivity,...
