Bifunctional performance of cellulose nanofibers grafted with polyhexamethylene guanidine in Pickering emulsion: Antibacterial activity and interfacial stability.
Int J Biol Macromol

School of Environment and Natural Resources, Zhejiang University of Science and Technology, Hangzhou 310023, China.
This study developed the multifunctional cellulose nanofibers (CNFs) as emulsifier for preparation of antibacterial, ultrastable and non-toxic emulsion. To achieve these properties, CNFs were oxidated using sodium periodate to introduce aldehyde groups, which served as Schiff-base reaction sites for amino groups of polyhexamethylene guanidine (PHMG), yielding PHMG-grafted CNFs (PCNFs). The modified CNFs retained good emulsification ability while acquiring antibacterial properties.

Herein, we report a novel electrochemical hydrogenolysis method for β-O-4 bond cleavage by using carbon foam as the cathode and waste aluminum as the anode. The reaction takes place at the cathode, producing ketones and phenolic compounds. Employing waste aluminum as the anode could avoid anodic excessive oxidation of phenols.

Background: This study aimed to investigate whether changes in capillary refill (CR) time precede macrovascular signs of deterioration in a human model of blood loss shock. The study was conducted at the Department of Emergency Medicine in Linköping, Sweden, and involved 42 healthy volunteers aged 18-45. Participants were randomized into two provocations of applied lower body negative pressure (LBNP): a stepwise escalation protocol and a direct application protocol, to simulate gradual and acute blood loss.

Objectives: Low-level laser therapy (LLLT) using an erbium-doped yttrium aluminum garnet (Er:YAG) laser provides a non-invasive approach applicable to various dental treatments. Here, we investigated the effects of Er:YAG laser irradiation on human dental pulp stem cells (hDPSCs) in an in vitro experiment.
Methods: The hDPSCs were categorized into four groups: laser-irradiated with activators (VLT: activated vitamin D, bone morphogenetic protein receptor inhibitor, and transforming growth factor-beta (TGF-β)) (LLLT(+)VLT), laser-irradiated without activators (LLLT(+)-only), non-irradiated with activators (LLLT(-)VLT), and non-irradiated without activators (control).
Selective production of olefins from methanol over a heteroatomic SAPO-34 zeolite.

The methanol-to-olefins (MTO) process has the potential to bridge future gaps in the supply of sustainable lower olefins. Promoting the selectivity of propylene and ethylene and revealing the catalytic role of active sites are challenging goals in MTO reactions. Here, we report a novel heteroatomic silicoaluminophosphate (SAPO) zeolite, SAPO-34-Ta, which incorporates active tantalum(V) sites within the framework to afford an optimal distribution of acidity.
