SmI2/Sm‐Induced Reductive Silacyclization of Alkene/Diene Derivatives Using Dichlorosilanes or 1,2‐Dichlorodisilanes via Reductive Radical‐Polar Crossover

open access: yesChemistry – A European Journal, EarlyView.
A SmI2/Sm‐mediated silacyclization unlocks a concise route to 4–7‐membered silacycles from simple unsaturated substrates and dichlorosilanes/disilanes. The complementary functions of samarium reductants trigger a reductive radical–polar crossover, offering a versatile strategy for constructing multiple Si─C bonds efficiently.

Porous Organic Frameworks‐Based Nanomaterials in Colorectal Cancer Therapy: From Drug Delivery to Personalized Nano‐Vaccine

open access: yesCancer Nexus, EarlyView.
ABSTRACT Colorectal cancer (CRC), as the second most common cause of cancer death worldwide, has seen a significant increase in its incidence rate in recent years. However, the current major clinical treatment methods, such as surgery, chemotherapy and radiotherapy, still have certain limitations and are difficult to achieve a complete cure.

Risk of Acute Kidney Injury Associated With Nephrotoxic Burden in Hospitalized Patients: A Scoping Review

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Limited evidence exists synthesizing the risk of acute kidney injury (AKI) associated with the concomitant administration of multiple nephrotoxic drugs, and even less examining the concept of nephrotoxic burden. The objective of this scoping review was to (1) identify definitions of nephrotoxic burden; (2) methods used to quantify (use of calculations)

Oogenesis and germinal bed morphology of the brown anole (A. sagrei)

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The brown anole is a model species of the genus Anolis, a squamate (encompassing lizards and snakes) group widely studied in evolutionary, behavioral, and developmental biology. Full genome annotation, the establishment of gene editing techniques, and comprehensive description of reproductive tract morphology and embryogenesis in ...

Redox‐Mediating Mo2C Nanoparticles Confined Within Nitrogen‐ and Phosphorus‐Codoped Amorphous Carbon Matrix for Lithium–Sulfur Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A multifunctional interlayer composed of Mo2C nanoparticles embedded in a nitrogen‐ and phosphorus‐doped amorphous carbon matrix on graphene is developed via electrostatic self‐assembly and thermal transformation. The resulting architecture suppresses the shuttle effect, improves electrical conductivity, and facilitates redox conversion kinetics ...

Strong Nonradiative Recombination Induced by Pronounced Lone‐Pair Electron Expression Following Deprotonation in Aziridinium Lead Iodide Perovskites

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The transition from linear to cyclic organic cations promotes deprotonation and activates VH(N) defects with pronounced lone‐pair electron activity, thereby inducing severe local distortions and highly efficient nonradiative recombination centers. This work unveils a direct structure–defect–performance correlation and proposes design strategies for the

Bottlenecks‐Breaking in Zinc‐Iodine Batteries Toward Practical Implementation: A Review and Perspective

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Aqueous zinc–iodine batteries (Zn–I2Bs) offer promise for grid storage due to safety and cost advantages yet face critical bottlenecks: severe self‐discharge (polyiodide shuttling and HER), limited energy density, sluggish kinetics, and zinc anode instability.
