Low‐Temperature in Situ Upgrading of Ultra‐Deep Heavy Oil Using Ni–Ce/MOF–OTf Superacid Catalysts to Enhance Energy Utilization and Sustainability

EcoEnergy, EarlyView.
A triflate‐functionalized Ni–Ce/MOF–OTf superacid enables low‐temperature (∼140°C) in situ upgrading of ultra‐deep heavy oil. It reduces viscosity by 92.11% in 12 h, maintains activity over cycles, and delivers 90.25% recovery with a lower carbon footprint by selective bond cleavage. ABSTRACT Ultra‐deep heavy oil is an important unconventional resource,

Enhanced Selectivity in 4-Quinolone Formation: A Dual-Base System for Palladium-Catalyzed Carbonylative Cyclization with Fe(CO)₅

Molecules
The use of gaseous CO in Pd-catalyzed carbonylative quinolone synthesis presents challenges related to safety and precise pressure control. In response, a streamlined non-gaseous synthesis of 4-quinolone compounds has been developed.

Reversal of Chronic Stress‐Induced Inflammaging by Bazi Bushen Formula Through AMPK‐Sirtuins Axis Activation and Myeloid Reset

Exploration, EarlyView.
Chronic stressors trigger systemic immune remodeling marked by myeloid expansion and lymphoid suppression, and this immune imbalance subsequently drives tissue pathology through proinflammatory signaling and senescence amplification, with the lung and kidney confirmed as the most vulnerable target organs.

Photo‐Promoted Nitrogen‐Centered Radical Mediated Intermolecular Aminative Carbonylation of Tertiary Allyl Alcohols to Access β‐Amino Ketones through (Hetero)Aryl Migration

ChemistryEurope
Carbon monoxide, as a crucial C1 synthon, has been widely used in the difunctionalization of alkenes. Additionally, nitrogen‐centered radicals (NCRs) are also effective intermediates for constructing C−N bonds.

Stripping‐based approach for the recovery of volatile fatty acids from anaerobic digestion digestate: preliminary experimental investigations and modelling

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Volatile fatty acids (VFAs) are widely used across industries: as intermediates in chemical production (e.g., solvents and polymers), in pharmaceuticals and cosmetics, and as preservatives and health‐promoting additives in food and animal feed. Emerging applications also include bioplastics, bioenergy, and biotechnology.

Combined effects of kombucha consumption and aerobic exercise on oxidative stress and metabolic parameters in Wistar rats

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Background Kombucha, a fermented tea containing symbiotic bacteria and yeast, and aerobic exercise each confer distinct health benefits, but their combined effects remain poorly understood. This study investigated the combined effects of consuming kombucha fermented for 7 days and performing moderate aerobic exercise on physiological outcomes ...

The Regulatory Role and Mechanism of Myoferlin in Mitophagy During Papillary Thyroid Carcinogenesis

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Papillary thyroid carcinoma (PTC) is the most prevalent subtype of thyroid cancer; however, the regulatory mechanisms by which mitophagy influences its progression remain inadequately elucidated. This study sought to examine the role of myoferlin (MYOF) in mitophagy and its molecular basis during PTC development. Utilizing three paired PTC and
