Stable Cobalt-Zeolite Propane-Dehydrogenation Catalysts Enabled by Reaction-Driven Reconstruction.

Cobalt-based catalysts have emerged as promising substitutes for Pt- and Cr-based propane dehydrogenation (PDH) catalysts. However, controlling the distribution of Co species and achieving stable active centers remains challenging. Here, we report that reaction-driven reconstruction of metallic cobalt (Co0) species within pure silica MFI zeolite (S-1) into CoOx clusters within silanol nests during PDH yields efficient and durable performance.

Selective Photocatalytic Aerobic Oxidation of Methane to Methyl Hydroperoxide by ZnO-Loaded Single-Atomic Ruthenium Oxide Catalyst.

Photooxidation of CH to value-added chemicals with high selectivity offers a promising pathway to drive the rational utilization of natural gas resources with renewable energy under mild conditions. However, owing to the poor chemoselectivity of reactive oxygen radical formation and consecutive side reactions of primary products, the synthesis of peroxide directly from CH oxidation remains challenging. Here, we report single-atom ruthenium oxide-doped ZnO as a highly selective photocatalyst for the aerobic oxidation of CH to CHOOH.

Dual effects of exogenous ferulic acid bound in rice starch as 3D printable food ink: Structural fluidity and antimicrobial activity.

Starch-ferulic acid (FA) composites have been developed for medical and food fields, while little focus is caused on their use in functional products by 3D printing. In this work, dynamic high-pressure microfluidization was employed to treat starch at various concentrations, for preparing modified starch-FA composites. The high-performance liquid chromatography results showed that an increased starch concentration was conducive to a high yield of composite with enhanced binding of FA.

Few studies are concerned with the effect of the conjugat protein on the bioactivities of the abalone gonad polysaccharide (AGP). In this study, a series of treatments, including raw material (female and male) defatting, extraction temperature (25-121 °C), proteolysis, ultrafiltration, and ethanol precipitation, was conducted to investigate the role of the conjugate protein on AGP anticoagulant activity. All AGP extracts significantly prolonged activated partial thromboplastin time (APTT) and thrombin time (TT).

Morphological modulation of starch chains from nanorod to nanospindle via temperature-controlling rearrangement.

Polymorphic nanoparticles, including starch nanoparticles (SNPs), have increasingly attracted attention, particularly rod-shaped variants, which are used for constructing anisotropic systems. Compared to symmetrically spherical particles, they show superior properties such as gastrointestinal retention for functional nutrients/drugs delivery and mechanical enhancement of filled materials, but their controlled fabrication remains a challenge. In this study, we yielded polymorphic SNPs with nearly axisymmetric geometries through a combined alkaline hydrolysis and nanoprecipitation method, followed by temperature-controlling rearrangement.

Performance Descriptor of Subsurface Metal-Promoted Boron Catalysts for Low-Temperature Propane Oxidative Dehydrogenation to Propylene.

Regulating Spin Polarization via Axial Nitrogen Traction at Fe-N Sites Enhanced Electrocatalytic CO Reduction for Zn-CO Batteries.

Single Fe sites have been explored as promising catalysts for the CO reduction reaction to value-added CO. Herein, we introduce a novel molten salt synthesis strategy for developing axial nitrogen-coordinated Fe-N sites on ultrathin defect-rich carbon nanosheets, aiming to modulate the reaction pathway precisely. This distinctive architecture weakens the spin polarization at the Fe sites, promoting a dynamic equilibrium of activated intermediates and facilitating the balance between *COOH formation and *CO desorption at the active Fe site.

Nanostarch-Stimulated Cell Adhesion in 3D Bioprinted Hydrogel Scaffolds for Cell Cultured Meat.

Three-dimensional (3D) bioprinting has great potential in the applications of tissue engineering, including cell culturing meat, because of its versatility and bioimitability. However, existing bio-inks used as edible scaffold materials lack high biocompatibility and mechanical strength to enable cell growth inside. Here, we added starch nanoparticles (SNPs) in a gelatin/sodium alginate (Gel/SA) hydrogel to enhance printing and supporting properties and created a microenvironment for adherent proliferation of piscine satellite cells (PSCs).

Organophosphate esters (OPEs) are frequently used as flame retardants and plasticizers in various commercial products. While initially considered as substitutes for brominated flame retardants, they have faced restrictions in some countries due to their toxic effects on organisms. We collected 37 soil and crop samples in 20 cities along the coast of South China, and OPEs were detected in all of them.

Combined effect of time in target range and variability of systolic blood pressure on cardiovascular outcomes and mortality in patients with hypertension: A prospective cohort study.

Time in target range (TTR) and blood pressure variability (BPV) of systolic blood pressure (SBP) are independent risk factors for major adverse cardiovascular events (MACE) and all-cause mortality in hypertensive patients. However, the association of the combination of low TTR and high BPV of SBP with the risk of MACE and all-cause mortality is unclear. This study sought to investigate the combined effect of the TTR and BPV on the risk of MACE and all-cause mortality in patients with hypertension.

Thermally stable Ni foam-supported inverse CeAlO/Ni ensemble as an active structured catalyst for CO hydrogenation to methane.

Nickel is the most widely used inexpensive active metal center of the heterogeneous catalysts for CO hydrogenation to methane. However, Ni-based catalysts suffer from severe deactivation in CO methanation reaction due to the irreversible sintering and coke deposition caused by the inevitable localized hotspots generated during the vigorously exothermic reaction. Herein, we demonstrate the inverse CeAlO/Ni composite constructed on the Ni-foam structure support realizes remarkable CO methanation catalytic activity and stability in a wide operation temperature range from 240 to 600 °C.

Portable Mid-Infrared Spectroscopy Combined with Chemometrics to Diagnose Fibromyalgia and Other Rheumatologic Syndromes Using Rapid Volumetric Absorptive Microsampling.

The diagnostic criteria for fibromyalgia (FM) have relied heavily on subjective reports of experienced symptoms coupled with examination-based evidence of diffuse tenderness due to the lack of reliable biomarkers. Rheumatic disorders that are common causes of chronic pain such as rheumatoid arthritis, systemic lupus erythematosus, osteoarthritis, and chronic low back pain are frequently found to be comorbid with FM. As a result, this can make the diagnosis of FM more challenging.
