Highly stable and active catalysts are of significant importance and a longstanding challenge for a number of industrial chemical transformations. Here, motivated by the principle of the high entropy-stabilized structure, high-entropy alloy-loaded porous TiO2 as an efficient and sintering-resistant catalyst for the light-driven reverse water gas‒shift reaction without external heating is synthesized

We welcome you to this Special Issue of Advanced Materials entitled “Engineering active materials for biomedical applications”. This special issue focuses on the design and application of biomedical materials that are engineered to be active, in either or both a biological and mechanical context. Current and future biomedical materials at a variety of size scales are highlighted, including their design

As a major component of tumor infiltration, tumor-associated macrophages (TAMs) primarily promote the M2 phenotype of tumors in the tumor microenvironment. Additionally, the overexpression of anti-phagocytic molecules in TAMs facilitates tumor cell evasion of TAMs’ phagocytic arrest. Therefore, there is an urgent need to develop a reliable strategy to reprogram TAMs for more effective anti-tumor outcomes

In this study, a series of dopant-free, low-cost hole-transporting materials (HTMs) based on triphenylamine-functionalized azadipyrromethene dyes 1–3 (TPA-ADPs 1–3) were designed and synthesized. The properties of these new HTMs were investigated by optical spectroscopy, cyclic voltammetry, thermogravimetric analysis, differential scanning calorimetric, atomic force microscopy, and X-ray diffraction

Recent developments have introduced a groundbreaking form of collinear magnetism known as “altermagnetism”. This emerging magnetic phase is characterized by robust time-reversal symmetry breaking, antiparallel magnetic order, and alternating spin-splitting band structures, yet it exhibits vanishing net magnetization constrained by symmetry. Altermagnetism uniquely integrates traits previously considered

The electrocatalytic nitrate reduction reaction (NO3−RR) presents a promising pathway for achieving both ammonia (NH3) electrosynthesis and water pollutant removal simultaneously. Among various electrocatalysts explored, 2D materials have emerged as promising candidates due to their ability to regulate electronic states and active sites through doping. However, the impact of doping effects in 2D materials

The iron-based mixed polyanionic compound Na4Fe3(PO4)2P2O7 (NFPP) with high theoretical capacity and excellent structural stability has attracted comprehensive attention as a promising cathode material for sodium-ion batteries (SIBs). Nevertheless, the constrained conductivity and restricted diffusion kinetics during sodium storage pose an unprecedented challenge to rate capability and cycling stability

Aqueous zinc-ion batteries (AZIBs) are hopeful energy storage devices due to their low cost and high energy density. However, the side reactions and the growth of dendrites at the anode limit the electrochemical performance of AZIBs. Optimizing the electrode process is crucial for enhancing the performance of AZIBs. Zn2+ are transported between cathode and anode through the electrolyte under the influence

Metal-organic frameworks (MOFs) have emerged as a transformative class of materials, offering unprecedented versatility in applications ranging from energy storage to environmental remediation and photocatalysis. This groundbreaking review navigates the recent advancements in MOFs, positioning them against traditional materials to underscore their unique strength and potential drawbacks. In the context
