Metal Bis(acyclic diaminocarbene)-Derived Homochiral Organometallic Frameworks: Synthesis and Asymmetric Catalytic Application.

As an indispensable member of the reticular material family, metal-carbon-based organometallic frameworks (OMFs) remain largely underexplored, and no chiral OMFs (COMFs) have been reported thus far. Herein, we first report the construction of COMFs from a Pd-isocyanide OMF via nucleophilic addition to the Pd-isocyanide moiety with optically pure amines. The obtained Pd-bis(acyclic diaminocarbene) (Pd-BADC)-derived chiral OMFs display excellent applicability and can be reusable chiral catalysts to highly promote asymmetric Strecker and Suzuki-Miyaura cross-coupling reactions in a heterogeneous way.

Halogen-Free Wide Band Gap Polymer Donors Based on Dicyanobithiophene for Efficient Organic Solar Cells.

Conjugated polymer donors have always been one of the important components of organic solar cells (OSCs), particularly those featuring simple synthetic routes, proper energy levels, and appropriate aggregation behavior. In this work, we employed a nonfused electron-deficient building block, dicyanobithiophene (2CT), for constructing high-performance donors. Combining this with side-chain engineering, two novel halogen-free polymer donors, PB2CT-BO and PB2CT-HD, were reported.

Effectiveness and safety of traditional Chinese therapies intreating patients with amyotrophic lateral sclerosis: a protocol for systematic review and meta-analysis.

Background: Amyotrophic lateral sclerosis (ALS) is a chronic, progressive disease that affects both upper and lower motor neurons. Some physicians have used traditional Chinese therapies (TCT) to treat ALS. However, there has been no systematic review or meta-analysis to evaluate the effectiveness and safety of TCT interventions.

Cu-doped waste-tire carbon as catalyst for UV/HO oxidation of ofloxacin.

Ofloxacin (OFX), commonly employed in the treatment of infectious diseases, is frequently detected in aquatic environments and poses potential ecological risks. UV/HO oxidation has been recognized as an efficient approach for removing antibiotics. In this study, Cu-doped waste-tire carbon was prepared and used as a UV/HO catalyst for the degradation of OFX.

[Mechanism of Colquhounia Root Tablets in inhibiting osteoclast differentiation based on HSP90 target modulation].

This study aimed to investigate the potential role of Colquhounia Root Tablets against bone destruction in rheumatoid arthritis(RA) and its molecular mechanism. The study used ultra-performance liquid chromatography-mass spectrometry to analyze the major components of Colquhounia Root Tablets and predicted its candidate target gene set based on the major components. The key targets of RA bone destruction were obtained through GeneCards and the Database of Genetics and Medical Literature(OMIM), protein-protein interaction(PPI) network was constructed, and the key targets were identified by topological analysis.
