The combination of radiation therapy (radiotherapy) with immunotherapy is changing the landscape of cancer treatment. Radiation damage tumor cell DNA through high-energy rays directly causes cell death or growth arrest; Immunotherapy works by boosting a patient's own immune system's ability to recognize and destroy cancer cells. The combination of the two not only enhances the local control of the tumor, but may also activate the systemic anti-tumor immune response, transforming the "cold" tumor into a "hot" tumor, thereby improving the survival rate and quality of life of patients.

The aqueous rechargeable magnesium ion batteries (ARMBs) are considered as one of the promising alternatives for the lithium organic batteries (Libs). However, the strong Coulombic repulsion brought by divalent alkaline earth metal ions (Mg) poses a new challenge to the stability of electrode materials. We present for the first time the introduction of a ternary medium-entropy effect (Fe, Mn and Co) at the 4b-active-site of the high spin (HS) of the Prussian blue analog (named KMEHCF) to enhance the "sp-mixing" effect of its cyanogen structure.

Developing multicomponent materials with high activity and establishing the precise regulation tactics of electronic structures at active sites, as well as their underlying mechanism of catalytic activity, are of great significance for oxygen evolution reaction (OER) electrocatalysis. In this study, we utilize the NaCl-templated assisted pyrolysis tactics to prepare a quinary NiCoFeMoZn catalyst, one heterostructure formed between a Zn-doped NiCoFe alloy and MoC-based phases within a carbon sponge. This smart design enables an effective dual-mode electronic structure fine-tuning strategy, incorporating entropy-induced modulation and metal-support interactions to precisely regulate the electronic structure of Ni active sites and enhance electrocatalytic activity.

Polyolefin elastomers (POEs) serve as versatile materials bridging rubber and plastic properties across a variety of industrial processes, but their environmental persistence stemming from inert hydrocarbon composition raises ecological concerns. Here, we present a sustainable synthesis of degradable thermoplastic elastomers (TPEs) through the carbonylative polymerization of ethylene and biomass-derived polar monomers (PMs). A cost-effective and scalable nickel catalyst has overcome the dual poison to metal center resulted from polar acid or ester motif and CO, enabling the synthesis of high-molecular-weight polyketone materials with moderate strain recovery (SR) values ranging from 27% to 61%.

Triboelectric nanogenerators (TENGs) are positioned as a critical sustainable power solution for harvesting low-frequency mechanical energy or sensing. Although solid-solid contact-based TENGs can provide sustainable power to diminish external battery reliance and enhance portability and operational longevity, suboptimal energy output at low-frequency excitation, irreversible material damage under long-term operation and inadequate energy supply remain a challenge. Solid-liquid contact-based TENGs present an alternative approach, but rigid and bulky configurations hinder their integration toward wearable devices and the development of real applications.

Hydrogen spillover, the migration of metal-activated hydrogen species across support surfaces, is key for many H-related reactions. However, questions remain about how the metal/oxide interfaces affect hydrogen spillover and hydrogenation reaction. Here, we construct MnO-on-Pt(111) (MnO/Pt(111)) inverse catalyst and Pt clusters-on-MnO (Pt/MnO) catalyst, and image hydrogen spillover behavior using high-pressure scanning tunneling microscopy.

The chromium (Cr) pollution in the soil poses serious ecological risks because hexavalent chromium (Cr) has high mobility and carcinogenicity, and its main source is the oxidation of the unstable form of trivalent chromium (Cr) in the soil. Traditional metal oxide-modified biochar has limited ability to passivate trivalent chromium (Cr) due to its low surface electron density. To address this issue, we propose a chlorine ion-induced electron enrichment strategy, taking advantage of the strong electrophilicity of chlorine ions (Cl).

Stable operation over wide temperature ranges is still a great challenge for lithium-sulfur batteries facing actual operating environments. Electrocatalysis is an effective strategy to address the sluggish reaction kinetics of lithium polysulfides at low temperatures and exacerbated shuttling effect at high temperatures; however, its practicality is still restricted by the structural stability of the support electrodes. In this work, a binder with wide temperature range adaptability is designed with a structure-modulated stable electrocatalytic mechanism, which can achieve effective adsorption and accelerated conversion of lithium polysulfides, and high-temperature self-repair and low-temperature internal support of electrodes.

Cancer immunotherapy has transformed oncology, with CAR-T cell therapy emerging as a cornerstone of personalized treatment for hematologic malignancies. In China, rapid advancements in domestically developed CAR-T therapies have achieved clinical outcomes comparable to global benchmarks, with overall response rates (ORR) of 79-89% in B-cell malignancies and 64% 12-month progression-free survival in multiple myeloma. Despite these successes, CAR-T application in solid tumors remains hindered by antigen heterogeneity, immunosuppressive microenvironments, and on-target/off-tumor toxicity.

Modulating surface-active hydrogen (*H) supply represents a critical strategy to boost the electrocatalytic CO reduction reaction (ECRR), yet the mechanistic interplay between *H dynamics and catalytic behavior remains ambiguous. Herein, we construct tandem catalysts (M/NiNC, M = Fe, Co, Cu, or Mn) by coupling tetranuclear metal clusters (M) with single-atom Ni sites on N-doped carbon (NiNC) to regulate *H supply. Experimental and theoretical results reveal that the *H supply is governed by both thermodynamics and kinetic factors.
