Structure Influence of Amine-Containing Additives on the Solution State and Out-of-Plane Conductivity of PEDOT:PSS for Efficient Organic Solar Cells.

Additives are extensively explored for improving PEDOT:PSS performances mainly through the removal of excess PSS and as a secondary dopant. In this work, amine-containing additives are introduced to PEDOT:PSS solutions as processing additives where the interactions to the PSS are anticipated through electrostatic interactions. Such interactions affected solution property where the increased viscosity is found to significantly increase the out-of-plane conductivity of the PEDOT:PSS thin films.

Dual mRNA co-delivery for in situ generation of phagocytosis-enhanced CAR macrophages augments hepatocellular carcinoma immunotherapy.

Hepatocellular carcinoma (HCC) is a prevalent and lethal disease, and tumor regression rarely occurs in advanced HCC patients due to limited effective therapies. Given the enrichment of macrophages in HCC and their role in tumor immunity, transforming them into chimeric antigen receptor macrophages (CAR-Ms) is thought to increase HCC cell-directed phagocytosis and tumoricidal immunity. To test this hypothesis, mRNA encoding CAR is encapsulated in a lipid nanoparticle (LNP) that targets liver macrophages.

Isolation and Extraction of Monomers from Insoluble Dietary Fiber.

Insoluble dietary fiber is a macromolecular polysaccharide aggregate composed of pectin, glycoproteins, lignin, cellulose, and hemicellulose. All agricultural by-products contain significant levels of insoluble dietary fiber. With the recognition of the increasing scarcity of non-renewable energy sources, the conversion of single components of dietary fiber into renewable energy sources and their use has become an ongoing concern.

Highly Tough and Biodegradable Poly(ethylene glycol)-Based Bioadhesives for Large-Scaled Liver Injury Hemostasis and Tissue Regeneration.

Conventional tissue adhesives face challenges for hemostasis and tissue regeneration in large-scaled hemorrhage and capillary hypobaric bleeding due to weak adhesion, and inability to degrade at specific sites. Herein, convenient and injectable poly(ethylene glycol) (PEG)-based adhesives are developed to address the issues for liver hemostasis. The PEG-bioadhesives are composed of tetra-armed PEG succinimide glutarate (PEG-SG), tetra-armed PEG amine (PEG-NH ), and tri-lysine.

Regulating the Polypyrrole Ion-Selective Membrane and Au Solid Contact Layer to Improve the Performance of Nitrate All-Solid Ion-Selective Electrodes.

With polymerization duration and Au concentration of the electrolyte regulated, a desirable nitrate-doped polypyrrole ion-selective membrane (PPy(NO)-ISM) and Au solid contact layer of anticipate surface morphology were obtained, and the performance of nitrate all-solid ion-selective electrodes (NS ISEs) was improved. It was found that the roughest PPy(NO)-ISM remarkably increases the actual contact surface area of the PPy(NO)-ISMs with nitrate solution, which leads to better adsorption of NO ions upon the PPy(NO)-ISMs, and produces a larger number of electrons. The most hydrophobic Au solid contact layer avoids the formation of the aqueous layer at the interface between the PPy(NO)-ISM and Au solid contact layer, and ensures unimpeded transporting of the produced electrons.

Rice potassium transporter OsHAK18 mediates phloem K loading and redistribution.

High-affinity K transporters/K uptake permeases/K transporters (HAK/KUP/KT) are important pathways mediating K transport across cell membranes, which function in maintaining K homeostasis during plant growth and stress response. An increasing number of studies have shown that HAK/KUP/KT transporters play crucial roles in root K uptake and root-to-shoot translocation. However, whether HAK/KUP/KT transporters also function in phloem K translocation remain unclear.

Unraveling the Selectivity and Synergistic Mechanism of Cu-Based Alloys for CO Reduction.

Understanding the synergistic effect of Cu-based alloys on the adsorption behavior and selectivity of the CO reduction reaction is a crucial step toward directional catalyst design. To this end, density functional theory calculations are employed to investigate Cu-based alloys with diverse doping elements and contents. The results show that the scaling relation still holds in the alloy system, and the strategies to improve the selectivity are put forward based on the adsorption strength of *C and *OCHO intermediates.
