Human mesenchymal stromal cells (MSCs) are attractive for both medical practice and biomedical research. Nonfreezing short-term storage may provide safe and simple transportation and promote the practical use of MSCs. We aimed to determine the duration of efficient storage at ambient temperature (22°C) of human dermal MSCs in different three-dimensional organization and to investigate the role of cell metabolic mode in the resistance to the ambient storage damaging factors.

Recent explorations into cinnamaldehyde (CIN) have identified its potential as a natural preservative, particularly when incorporated into active packaging to enhance the shelf-life of fruits and vegetables. This study explores the use of cellulose nanofiber (CNF)-stabilized Pickering emulsions as a novel delivery system for essential oils, demonstrating broad applicability in food preservation strategies. We employ CNF as Pickering stabilizers to effectively emulsify and encapsulate CIN, investigating the influence of tannic acid (TA) concentrations on the stability of these emulsions.

In this work, a battery layup consisting of a poorly flammable ionic liquid electrolyte and a poly(vinylidene fluoride--hexafluoropropylene) (PVdF-HFP) thermoplastic has been developed along with composite anode and cathode electrodes. The developed gel electrolyte exhibits feasible ionic conductivity of about 1 mS/cm at 30 °C. State-of-the-art active electrode materials, i.

Oxidation is a fundamental transformation in synthesis. Developing facile and effective aerobic oxidation processes under ambient conditions is always in high demand. Benefiting from its high energy and good penetrability, ionizing radiation can readily produce various reactive species to trigger chemical reactions, offering another option for synthesis.

Coordination polymers (CPs) are promising for direct X-ray detection and imaging owing to higher designability and outstanding stability, however, it remains a challenge to achieve highly X-ray detection performance, particularly both high sensitivity and low detection limit at the same operating voltage. Herein, we construct a new conjugated CP {[Co(BPTTz)(DIPA)] DMA}n (1, BPTTz = 2,5-bis(pyridine-4-yl)thiazolo[5,4-d]thiazole, H2DIPA = 2,5-diiodoterephthalic acid, DMA = N, N'-dimethylacetamide), with multi-channel charge transfer by regulating the linker mediated electronic-state, which reduces carrier losses resulting from recombination or quenching, enhances the efficiency of charge separation and transfer, thus further optimizes X-ray detection performance. The semiconductor prepared based on this strategy achieves record values including the highest mobility-lifetime product (μτ, 8.
