Synergetic Ruthenium Clusters and Ligand Motifs in Insoluble Polyoxometalates for Efficient Urea Electrosynthesis

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The electrocatalytic co‐reduction of CO2 and nitrate (NO3− ${\text{NO}}_{3}^{-}$) to synthesize urea presents a sustainable alternative to traditional industrial processes, yet its efficiency is fundamentally limited by the kinetically mismatched activation and coupling of CO2 and NO3− ${\text{NO}}_{3}^{-}$.

Synergy Effects of Dual‐Gel‐Assisted Structural Engineering and Bimetallic Doping Regulation Realize Ultrastable High‐Rate Performance of NASICON Cathodes for Sodium‐Ion Batteries

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Na‐superionic‐conductor‐type (NASICON) Na4MnV(PO4)3 (NMVP) is an appealing cathode for sodium‐ion batteries (SIBs), but its application is hindered by Jahn–Teller distortions, sluggish Na+ kinetics and poor conductivity, leading to rapid capacity fade.

Hypertension at 5 months postpartum in women with gestational diabetes

open access: yesUltrasound in Obstetrics &Gynecology, Volume 68, Issue 2, Page 202-210, August 2026.
ABSTRACT Objective Gestational diabetes mellitus (GDM) is associated with future maternal cardiovascular disease, independent of the development of Type‐2 diabetes mellitus. As a major cardiovascular risk factor, we examined the incidence and predictors of hypertension at 5 months postpartum in women with previous GDM.

Revitalizing Traditional Tank Systems: Case Study Insights From Sri Lanka's Village Tank Cascade Systems for Climate Resilience and Water Governance

open access: yesWorld Water Policy, Volume 12, Issue 3, August 2026.
ABSTRACT Village tank cascade systems (VTCS) are a long‐established form of water management in Sri Lanka's dry zone. However, their role in groundwater recharge, climate adaptation, and water governance remains insufficiently recognized in policy and planning.

K-ras基因突变表达谱与结直肠癌肝转移的相关性分析

open access: yesZhongguo shiyan zhenduanxue, 2011
目的探讨K-ras基因突变谱与结直肠癌肝转移的相关性,为进一步阐明结直肠癌肝转移的分子机制提供理论依据。方法收集2008年1月至2010年8月在我院治疗的结直肠癌肝转移患者30例,进行K-ras基因突变检测,分析K-ras基因的突变类型及频率,探讨K-ras基因的突变谱与结直肠癌肝转移患者性别、年龄、原发灶位置、转移位置、病灶形态及TNM分期的相关性。结果 30例结直肠癌肝转移患者组织中K-ras基因突变者14例,突变率为47%,其中12密码子突变9例,突变率为30%;13密码子突变者5例,突变率为17%
