Inexpensive and easily available raw materials combined with practical and efficient preparation technology is an important direction for the future development of microwave absorption materials. In this study, coal tar pitch (CTP), an advantageous resource with low cost and wide source, be used as the carbon source. Hypercrosslinked porous polymers are prepared by crosslinking aromatic compounds in CTP based on the classical Friedel-Crafts reaction. Porous carbon (PC) microwave absorption materials will be prepared by high-temperature carbonization.

The study achieves efficient electrocatalysis for the electrooxidation reaction in multi-electrolyte systems by synergistically modulating structure and electronic coupling through rational design. The research team established novel principles for controlling the morphology and performance of MOFs: formation of nano-flower structure requires co-existence of Ni site and Fc ligand, doping of Fe sites promotes 3D crystal morphology development, which marks a pioneering advance in the field. Among them, the Bimetallic Dual-Ligand MOF: NFBF (6:2) exhibits outstanding electrocatalytic performance (210 mV at 10 mA·cm^-2). Operando Raman spectroscopy and XAFS reveal the electronic restructuring feature of NFBF (6:2) during the catalytic OER process. Combined with DFT calculations, which identify Ni as the catalytic active site, these investigations uncover significant electronic migration and redistribution, substantially reducing the reaction energy barrier and accelerating the catalytic process. Comprehensive exploration demonstrates that NFBF (6:2) not only performs well under various multi-electrolyte conditions but also maintains a nearly consistent catalytic mechanism. Furthermore, when applied to overall water splitting, (+) NFBF (6:2) | | NFBF (6:2) (-) achieves significant catalytic effects in both alkaline freshwater (1.40 V at 10 mA·cm^-2) and seawater (1.44 V at 10 mA· cm^-2) electrolyzers. This work highlights the crucial role of electronic coupling in optimizing electrocatalytic performance and offers new insights for addressing mitigating environmental pollution, embodying substantial practical and research potential.

Polyoxometalates (POMs) have broad applicability and significant potential in electrocatalysis and photocatalysis. However, the practical application of pure POMs is significantly constrained by their decomposition in polar media (such as neutral and alkaline solutions). The modification of POMs with metal-calixarene clusters is beneficial for fabricating functional hybrid materials with the combined merits of the two components. Four new thiacalixarene-functionalized polyoxometalate clusters were synthesized by researchers at School of Petrochemical Engineering, Liaoning Petrochemical University, China. These four clusters were characterized by Keggin-type PM₄Mo₈ motifs, which confer redox properties similar to those of PMo₁₂O₄₀³⁻ (PMo₁₂) while providing superior structural stability and electrocatalytic reduction of IO₃⁻. The substitution of four metal ions in PMo₁₂, along with the capping TC4A ligand and VO unit, significantly modulated visible-light absorption, enhancing photothermal conversion in the solid state and organic solutions.

Obesity-related metabolic disorders are driven by insulin resistance and inflammation, yet therapeutic efficacy of endogenous lipid mediators is limited by poor bioavailability and enzymatic degradation. Self-assembled vesicles combining inorganic clusters and lipid mediators improve glucose control, reduce inflammation, and promote weight loss in preclinical study.

The relentless down-scaling of electronics grands the modern integrated circuits (ICs) with the high speed, low power dissipation and low cost, fulfilling diverse demands of modern life. Whereas, with the semiconductor industry entering into sub-10 nm technology nodes, degrading device performance and increasing power consumption give rise to insurmountable roadblocks confronted by modern ICs that need to be conquered to sustain the Moore law’s life. Bulk semiconductors like prevalent Si are plagued by seriously degraded carrier mobility as thickness thinning down to sub-5 nm, which is imperative to maintain sufficient gate electrostatic controllability to combat the increasingly degraded short channel effects. Nowadays, the emergence of two-dimensional (2D) materials opens up new gateway to eschew the hurdles laid in front of the scaling trend of modern IC, mainly ascribed to their ultimately atomic thickness, capability to maintain carrier mobility with thickness thinning down, dangling-bonds free surface, wide bandgaps tunability and feasibility to constitute diverse heterostructures. Blossoming breakthroughs in discrete electronic device, such as contact engineering, dielectric integration and vigorous channel-length scaling, or large circuits arrays, as boosted yields, improved variations and full-functioned processor fabrication, based on 2D materials have been achieved nowadays, facilitating 2D materials to step under the spotlight of IC industry to be treated as the most potential future successor or complementary counterpart of incumbent Si to further sustain the down-scaling of modern IC.

In a recent publication in Medcomm-Oncology, a team of expert scientists specializing in immuno-oncology extensively outlined the complexities involved in the therapeutic targeting of transforming growth factor-beta (TGF-β) inhibition as a strategy for cancer immunotherapy. They discuss the significant hurdles in translating preclinical successes into effective clinical treatments, such as robust anti-tumor immune responses observed in in vitro and animal models. The authors analyze the multifaceted biological roles of TGF-β in tumor progression and immune regulation, and propose strategies to overcome these translational challenges, thereby enhancing the efficacy and safety of TGF-β-targeted therapies in clinical settings.

Surface-engineered LNPs, propelled by clinical successes like patisiran and mRNA vaccines, enable targeted nucleic acid delivery via ligands (antibodies, peptides) and conjugation chemistries (click reactions). These LNPs target organs (liver, lungs) and cells (immune, brain), advancing gene therapy and vaccines. Key challenges—batch reproducibility, ligand stability, scalable production—must be resolved to accelerate clinical translation and expand applications to protein/small-molecule delivery.

This protocol establishes the chorioallantoic membrane (CAM) model in avian embryos to investigate migrasome-mediated angiogenesis mechanisms. Key methodologies include the CAM nylon mesh assay and ex vivo sprouting assay for quantifying vascular growth, alongside migrasome isolation, labeling, and targeted delivery. CRISPR-generated T4-KO-mCherry-KI embryos enable functional analysis of migrasome dynamics in real-time angiogenesis. The CAM's high vascularity and accessibility allow parallel assessment of pro-/anti-angiogenic factors and migrasome-cell interaction mapping. By integrating genetic editing and migrasome manipulation, this platform bridges migrasome biology with developmental angiogenesis, offering a scalable tool for mechanistic and therapeutic exploration.
