Revising the coal mining CH emission factor based on multiple inventories and atmospheric inversion approach at one of the world's largest coal production areas: Shanxi province, China.

Methane (CH) emissions from the coal industry represent a substantial portion of anthropogenic CH emissions from energy-related activities. China ranks as the world's largest coal producer, where Shanxi Province is one of its major coal production regions and accounts for 20.7 % of the national total coal production.

Deep photocatalytic NO oxidation on ZnTi-LDH: Pivotal role of surface hydroxyls dynamic evolution.

Surface defect engineering has been regarded as an appealing strategy to improve photocatalytic performance, but defects are susceptible to inactivation and thus lose their function as active sites. In this study, we successfully tailored and identified the dynamic evolution of surface hydroxyl defects over ZnTi-layered double hydroxide (ZnTi-LDH) photocatalyst. The enrichment of surface hydroxyl electrons and the dynamic circulation of hydroxyl defects result in enhanced separation and transport capabilities of photogenerated carriers, thereby ensuring the perpetual activation of small molecules into •O and •OH.

Time dependency for human papillomavirus circulating tumor DNA detection after chemoradiation as a prognostic biomarker for localized anal cancer.

Background: While detection of circulating tumor DNA (ctDNA) weeks after surgery is linked to recurrence for other solid tumors, the optimal time point for ctDNA assessment as a prognostic biomarker following chemoradiation for anal cancer is undefined.

Methods: Patients with stages I-III anal cancer treated with chemoradiation between 12/2020-5/2024 were evaluated for HPV ctDNA status at baseline, at the end of chemoradiation, and during surveillance using a droplet digital HPV ctDNA PCR assay targeting HPV E6 and E7 oncogenes for 13 oncogenic HPV types. Median recurrence-free survival (RFS) according to HPV ctDNA status was estimated via Kaplan-Meier and compared using a log-rank test.

Polysiloxane-Modified PMMA-Shell Phase Change Microcapsules for Thermal Management Fabrics.

Critical issues such as leakage, degradation, and thermal response hysteresis have become the focus in the application of phase change materials (PCMs) in area such as thermal management of fabrics. The encapsulation of PCMs prepared as microcapsules using polysiloxanes, etc. as a component unit of crosslinking agents represents a highly promising avenue of research.

Identification and validation of prognostic biomarkers in ccRCC: immune-stromal score and survival prediction.

Background: The tumor microenvironment (TME) is integral to tumor progression. However, its prognostic implications and underlying mechanisms in clear cell renal cell carcinoma (ccRCC) are not yet fully elucidated. This study aims to examine the prognostic significance of genes associated with immune-stromal scores and to explore their underlying mechanisms in ccRCC.
