Effect of -Butyl Substitution on the Interactions of Cobalt Phthalocyanine with a Carbon Monoxide-Functionalized Tip.

Supported cobalt phthalocyanines (CoPc) are promising catalysts for CO reduction, a critical process for mitigating greenhouse gas emissions. Enhancing the catalytic performance of CoPc involves modifying the interaction between the cobalt center and intermediate species. This study focuses on the effects of -butyl substitution on CoPc using (-butyl)CoPc, where the substitution can both directly alter the molecule's intramolecular electronic structure and indirectly alter it by the bulky group weakening the interaction with the support.

Bone marrow stromal cell antigen 2: Tumor biology, signaling pathway and therapeutic targeting (Review).

Bone marrow stromal cell antigen 2 (BST2) is a type II transmembrane protein that serves critical roles in antiretroviral defense in the innate immune response. In addition, it has been suggested that BST2 is highly expressed in various types of human cancer and high BST2 expression is related to different clinicopathological parameters in cancer. The molecular mechanism underlying BST2 as a potential tumor biomarker in human solid tumors has been reported on; however, to the best of our knowledge, there has been no review published on the molecular mechanism of BST2 in human solid tumors.

In this paper, we present the modeling process, simulation procedure, and resulting design specifications for the qubit control system.

Uniform self-rectifying resistive random-access memory based on an MXene-TiO Schottky junction.

For filamentary resistive random-access memory (RRAM) devices, the switching behavior between different resistance states usually occurs abruptly, while the random formation of conductive filaments usually results in large fluctuations in resistance states, leading to poor uniformity. Schottky barrier modulation enables resistive switching through charge trapping/de-trapping at the top-electrode/oxide interface, which is effective for improving the uniformity of RRAM devices. Here, we report a uniform RRAM device based on a MXene-TiO Schottky junction.
