Traditionally, N-doped TiO (N-TiO) has been regarded as unsuitable for the oxygen evolution reaction (OER) under visible light. Ni-modified β-FeOOH nanorod cocatalysts enabled to use N 2p holes in the N-TiO photoanode induced by 400-500 nm visible light photons for the OER, enhancing anodic photocurrent of N-TiO with 13-fold with 100% faradaic efficiency.

Interface engineering and electronic modulation enable precise tuning of the electronic structure, thereby maximizing the efficacy of active sites and significantly enhancing the activity and stability of the electrocatalyst. Herein, a hybrid material composed of Ni-modified CoS nanoparticles ((Co, Ni)S) encapsulated within an N, S co-doped carbon matrix (SNC) and anchored onto S-doped carbonized wood fibers (SCWF) is synthesized using a straightforward simultaneous carbonization and sulfidation approach. Density functional theory (DFT) calculations reveal that the highly electronegative Ni element promotes electron cloud migration from Co to Ni, shifting the d-band center of Co closer to the Fermi level.

The novel two-dimensional MXene material TiCT boasts advantages such as large specific surface area, good electrical conductivity, and high stability, making it suitable for the field of electrocatalysis. However, TiCT exhibits unacceptably slow kinetics during the electrocatalytic hydrogen evolution reaction (HER). Electron-metal-support interaction is an effective method for regulating the electronic state of active sites and enhancing HER performance.

Hierarchical designing of (10 wt% - 70 wt%) nickel over HZSM-5 zeolite was done using wet-impregnation method. The material formation was established by XRD, BET, TPD and TEM studies. Optimization of reaction parameters for mixture of LDPE derived oil and waste cooking oil was found to be 450 °C, 4.

Anodic TiO nanotube arrays decorated with Ni, Cu, and NiCu alloy thin films were investigated for the first time for the photocatalytic degradation of paracetamol in water solution under UV irradiation. Metallic co-catalysts were deposited on TiO nanotubes using magnetron sputtering. The influence of the metal layer composition and thickness on the photocatalytic activity was systematically studied.

Sirtuin1 (SIRT1), an NAD-dependent histone deacetylase, plays a crucial role in regulating molecular signaling pathways. Recently, inhibition of SIRT1 rather than its activation shows the therapeutic potential for central nervous system disorder, however, the discovered SIRT1 inhibitors remains limited. In this work, a dual recognition-based strategy was developed to screen SIRT1 inhibitors from natural resources in situ.
