Modulating the Oxygen Evolution Reaction of Single-Crystal Cobalt Carbonate Hydroxide via Surface Fe Doping and Facet Dependence.

J Phys Chem Lett

January 2025

Graphene Composite Research Center, College of Chemistry and Environmental Engineering, Shenzhen University, Shenzhen 518060, P. R. China.

The oxygen evolution reaction (OER) is a critical half-reaction in water splitting and metal-air cells. The sensitivity of the OER to the composition and structure of the electrocatalyst presents a significant challenge in elucidating the structure-property relationship. In this study, highly stable single-crystal cobalt carbonate hydroxide [Co(OH)CO, CoCH] was used as a model to investigate the correlations among structure, composition, and reactivity.

Catalytic Asymmetric Dehydrogenative Si-H/X-H Coupling toward Si-Stereogenic Silanes.

Acc Chem Res

January 2025

Shenzhen Grubbs Institute and Department of Chemistry, Shenzhen Key Laboratory of Small Molecule Drug Discovery and Synthesis, Guangdong Provincial Key Laboratory of Catalysis, Southern University of Science and Technology, Shenzhen, Guangdong 518055, China.

ConspectusChiral organosilicon compounds bearing a Si-stereogenic center have attracted increasing attention in various scientific communities and appear to be a topic of high current relevance in modern organic chemistry, given their versatile utility as chiral building blocks, chiral reagents, chiral auxiliaries, and chiral catalysts. Historically, access to these non-natural Si-stereogenic silanes mainly relies on resolution, whereas their asymmetric synthetic methods dramatically lagged compared to their carbon counterparts. Over the past two decades, transition-metal-catalyzed desymmetrization of prochiral organosilanes has emerged as an effective tool for the synthesis of enantioenriched Si-stereogenic silanes.

January 2025

Key Laboratory of Industrial Ecology and Environmental Engineering (Ministry of Education, China), School of Environmental Science and Technology, Dalian University of Technology, Dalian 116024, China.

Electrochemical oxidation via in situ-generated reactive oxygen species (ROS) is effective for the mineralization of refractory organic pollutants. However, the oxidation performance is usually limited by the low yield and utilization efficiency of ROS. Herein, a B/N-doped diamond (BND) flow-through electrode with enhanced SO/OH generation and utilization was designed for electrochemical oxidation of organic pollutants in sulfate solution.

Long-term, immunosuppression-free allograft survival has been induced in human and nonhuman primate (NHP) kidney recipients after nonmyeloablative conditioning and donor bone marrow transplantation (DBMT), resulting in transient mixed hematopoietic chimerism. However, the same strategy has consistently failed in NHP heart transplant recipients. Here, we investigated whether long-term heart allograft survival could be achieved by cotransplanting kidneys from the same donor.

The development of surgical techniques, chemotherapy, biological agents, and multidisciplinary approaches have made patients with unresectable colorectal liver metastases eligible for surgery. Many strategies have been developed to allow patients for surgical resection (percutaneous portal vein embolization, liver venous deprivation, parenchyma-sparing liver surgery, reverse strategy, associating liver partition and portal vein ligation for staged hepatectomy, and liver transplantation), the only form of disease control and curative treatment.

In patients with synchronic liver colorectal metastasis, resection of the primary tumor and liver metastases is the only potentially curative strategy. In such cases, there is no consensus on whether resection of the primary tumor and metastases should be performed simultaneously or whether a staged approach should be performed (resection of the primary tumor and after, hepatectomy, or hepatectomy first). Patients with no bowel occlusion and with extensive liver disease are advised neoadjuvant oncological therapy.

Complete removal of metastatic disease and maintenance of an adequate liver remnant remains the only treatment option with curative intent concerning colorectal liver metastases. Surgery impacts on the long-term prognosis and complications adversely affect oncological results. The actual morbidity involving this scenario is debatable and estimated to be ranging from 15% to 50%.

Intercellular mRNA transfer alters the human pluripotent stem cell state.

Proc Natl Acad Sci U S A

January 2025

Human Biology Research Unit, Institute of Integrated Research, Institute of Science Tokyo, Bunkyo-ku, Tokyo 113-8510, Japan.

Intercellular transmission of messenger RNA (mRNA) is being explored in mammalian species using immortal cell lines. Here, we uncover an intercellular mRNA transfer phenomenon that allows for the adaptation and reprogramming of human primed pluripotent stem cells (hPSCs). This process is induced by the direct cell contact-mediated coculture with mouse embryonic stem cells under the condition impermissible for primed hPSC culture.

A periplasmic protein modulates the proteolysis of peptidoglycan hydrolases to maintain cell wall homeostasis in .

Proc Natl Acad Sci U S A

January 2025

Department of Biological Sciences, College of Natural Sciences, Sungkyunkwan University, Suwon 16419, Republic of Korea.

Bacterial cell wall assembly and remodeling require activities of peptidoglycan (PG) hydrolases as well as PG synthases. In particular, the activity of DD-endopeptidases, which cleave the 4-3 peptide crosslinks in PG, is essential for PG expansion in gram-negative bacteria. Maintaining optimal levels of DD-endopeptidases is critical for expanding PG without compromising its integrity.

The intricacy, diversity, and heterogeneity of cancers make research focus on developing multimodal synergistic therapy strategies. Herein, an oxygen (O) self-feeding peroxisomal lactate oxidase (LOX)-based LOX-Ce6-Mn (LCM) was synthesized using a biomineralization approach, which was used for cascade chemodynamic therapy (CDT)/photodynamic therapy (PDT) combination therapies through dual depletion of lactate (Lac) and reactive oxygen species (ROS) generation. After endocytosis into tumor cells, the endogenous hydrogen peroxide (HO) can be converted to O by the catalase-like (CAT) activity of LCM, which can facilitate the catalytic reaction of LOX to consume more Lac and alleviate tumor hypoxia to enhance the generation of singlet oxygen (O) upon light irradiation.

January 2025

Beijing Advanced Innovation Center for Materials Genome Engineering, Beijing Key Laboratory of Function Materials for Molecule & Structure Construction, School of Materials Science and Engineering, University of Science and Technology Beijing, Beijing 100083, P. R. China.

Photocatalytic detoxification of sulfur mustards (, bis (2-chloroethyl) sulfide, SM) is an effective approach for protecting the ecological environment and human health. In order to fabricate COFs with high performance for the selective transformation of the SM simulant 2-chloroethyl ethyl sulfide (CEES) to nontoxic 2-chloroethyl ethyl sulfoxide (CEESO), three porphyrin-based COFs with different donor groups (R = H, OH, and OMe) were synthesized. Among these COFs, COF-OMe, which possesses the strongest electron-donating ability, demonstrated a faster and higher detoxification rate of CEES at various concentrations, achieving selective oxidation of CEES to non-toxic CEESO with 99.
