Iron rust for efficient photocatalytic hydrogen evolution.

Iron (Fe) corrosion typically results in significant damage to Fe-based devices and structures. However, the corrosion products can be repurposed as active materials in electrocatalytic and photocatalytic reactions. In this study, we have strategically induced oxygen corrosion in Fe foams to synthesize cost-effective Fe rust cocatalysts (Orthorhombic FeOOH) for enhancing the photocatalytic hydrogen evolution reaction (HER), exemplifying the concept of "turning waste into treasure".

Dynamic Tailoring Porosity and Surface Chemistry of Ultramicroporous Carbon Spheres for Highly Selective Post-combustion CO Capture.

Carbon capture has emerged as a pivotal carbon neutrality technology for addressing greenhouse effect challenges. Porous carbons are one of the most promising adsorbents for CO capture and separation from flue gas, yet their traditional synthesis necessitates inert atmospheres to avoid oxidation, which greatly restricts the large-scale production at a low cost and advanced industrial applications. Herein, we propose an innovative pathway for large-scale fabrication of porous carbons via one-step pyrolysis in an air environment.

Molten salt synthesis of 1T phase dominated O-MoS for enhancing photocatalytic hydrogen production performance of CdS via Ohmic junction.

In photocatalysis, establishing an Ohmic junction could create an internal electric field between semiconductors and cocatalysts [1,2], effectively enhancing the transfer of photogenerated electrons. In this study, the 1T phase dominated oxygen atom doped MoS cocatalyst (O-MoS), synthesized from KSCN molten salt with in-situ oxidation for the first time, is combined with CdS for boosting photocatalytic hydrogen production. In the hybrid photocatalyst, electrons could be efficiently extracted from CdS to O-MoS due to the presence of Ohmic contact, thereby significantly enhancing the utilization of photogenerated electrons and the photocatalytic hydrogen evolution performance.

Rational Regulation of High-Entropy Perovskite Oxides through Hole Doping for Efficient Oxygen Electrocatalysis.

Due to the high configuration entropy, unique atomic arrangement, and electronic structures, high-entropy materials are being actively pursued as bifunctional catalysts for both the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) in rechargeable zinc-air batteries (ZABs). However, a relevant strategy to enhance the catalytic activity of high-entropy materials is still lacking. Herein, a hole doping strategy has been employed to enable the high-entropy perovskite La(CrMnFeCoNi)O to effectively catalyze the ORR and OER.

Resistant starch grafted cerium-sulfasalazine infinite coordination polymers synergistically remold intestinal metabolic microenvironment for inflammatory bowel disease therapy.

Inflammatory bowel disease (IBD) is a chronic gastrointestinal disease which is closely related with the overproduced reactive oxygen species (ROS), increased pro-inflammatory cytokines and disordered intestinal microbes. However, current therapeutic methods usually ignored the interrelation among the pathogenesis, and mainly focused on a single factor, inducing clinical outcomes unsatisfied. Herein, biocompatible infinite coordination polymers of drugs (Ce-SASP-RS ICPs) composed of Ce ions, FDA-approved drug sulfasalazine (SASP) and natural ingredient resistant starch (RS) were developed for synergistic treatment of IBD.

Bipolar plates are one of the most important components of proton exchange membrane fuel cells. With the miniaturization of bipolar plate flow channel sizes and the increasing demand for precision, springback has become a key focus of research in the bipolar plate forming process. In this paper, the hydroforming process for 316L stainless steel bipolar plates was studied, and an FEM model was built to examine the stress and strain at various locations on the longitudinal section of the plate.

Synthesis of large-sized spherical Co-C alloys with soft magnetic properties though a high-pressure solid-state metathesis reaction.

In this work, we report a novel high-pressure solid-state metathesis (HSM) reaction to produce spherical bulk (diameters 2-4 mm) Co-C alloys (CoC and CoC). At 2-5 GPa and 1300 °C, C atoms preferentially occupy the interstitial sites of the face-centered cubic (fcc) Co lattice, leading to the formation of metastable CoC. The CoC decomposes above 1400 °C at 2-5 GPa, C atoms infiltrate the interstitial sites of the fcc Co lattice, saturating the C content in Co, forming an fcc CoC solid solution while the C atoms in excess are found to precipitate in the form of graphite.

Artificial diets for silkworms overcome the seasonal limitations of traditional rearing methods with fresh mulberry leaves. However, the current wet artificial diets, steamed at high temperatures, are not favored by silkworms, and they are cumbersome and challenging to preserve. These conditions adversely affected the development of artificial diet-based sericulture production.

Chemodynamic therapy agent optimized mesoporous TiO nanoparticles for Glutathione-Enhanced and Hypoxia-Tolerant synergistic Chemo-Sonodynamic therapy.

Sonodynamic therapy (SDT) can generate reactive oxygen species to kill cancer cells by activating sonosensitizers under ultrasound (US) irradiation. Nevertheless, its application is greatly limited by low quantum yield of sonosensitizers, high levels of endogenous glutathione (GSH) and tumor hypoxia. Herein, a GSH-activated sonosensitizers with synergistic therapy effect (chemodynamic therapy (CDT) and SDT) are developed by depositing Fe(III)-artemisinin infinite coordination polymers (Fe(III)-ART CPs) in pores of mesoporous TiO nanoparticles (NPs).

The surfactant cetyltrimethylammonium bromide concentration is the key factor in the construction of this type of unique nanostructure.

A Novel Evaluation Method of Construction Homogeneity for Asphalt Pavement Based on the Characteristic of Component Distribution.

To effectively evaluate the construction homogeneity of asphalt pavement, the tomography image of a core sample of asphalt pavement was obtained via industrial computed tomography (CT) equipment. According to the characteristics of CT images, an improved separation algorithm based on annular partition and Nobuyuki Otsu (OTSU) threshold segmentation was proposed. Based on the distribution of aggregates, voids and asphalt mortar, and the area ratio of each part in the CT images inside the pavement, a novel evaluation method for the distribution homogeneity of asphalt pavement components was put forward, and the validity of the evaluation index was also verified.

A sustainable one-step strategy for highly graphitized capacitive carbons with hierarchical micro-meso-macro porosity.

Large micropore surface area, superior electrical conductivity and suitable pore size are simultaneously desired characteristics for high-performance capacitive carbons. However, these desired features tend to be mutually competing, and are generally difficult to integrate into a single carbon. Considering this challenge, we developed a sustainable, less time-demanding, pollution-free strategy to construct highly graphitized porous carbon (GPC) by one-step heat-treatment.

AKR1C1 alleviates LPS‑induced ALI in mice by activating the JAK2/STAT3 signaling pathway.

Acute lung injury (ALI) is a respiratory tract disease characterized by increased alveolar/capillary permeability, lung inflammation and structural damage to lung tissues, which can progress and transform into acute respiratory distress syndrome (ARDS). Although there are several treatment strategies available to manage this condition, there is still no specific cure for ALI.
