Abstract:
... The optical properties and humidity response of iridescent films made of cellulose nanocrystal (CNC) and polyethylene glycol (PEG) can be tailored by the incorporation of electrolytes chosen based on specific ion effects (SIE). A series of inorganic salts comprising five different cations and five anions based on the Hofmeister series were mixed with CNC/PEG suspensions, followed by an air-dried p ...

Abstract:
... Novel phase change materials composed of polyethylene glycol (PEG), cellulose nanofibers (CNFs) and carbon nanotubes (CNTs) were developed by an efficient and environment friendly strategy. The CNFs were modified and cross-linked by chitosan to form three-dimensional network structure, which provides strong support for the resulting CNF/CNT/PEG composites. The structure and properties of CNF/CNT/P ...
... The hypoxic tumor microenvironment and photodynamic therapy (PDT)-aggravated hypoxia compromise the anticancer efficacy of chemotherapy, immunotherapy, and PDT. Thus, sophisticated nanomedicines that can activate their anticancer capability in situ in response to specific stimuli need to be developed. This study aimed to construct a hybrid nanomedicine that activated chemotherapy by inducing hypox ...
... Mother of FT and TFL1 (MFT) is a member of the phosphatidylethanolamine-binding protein (PEBP) family, which plays important roles in seed development, the stress response, and flowering time regulation. In the present study, the MFT homologous gene MiMFT was identified in mango cultivar ‘SiJiMi’. The promoter of MiMFT contained phytohormone-, plant growth-, plant development-, and abiotic stress- ...

Abstract:
... In this work, we report a high-yield one-pot synthesis of polyrotaxane (PR), composed of (2-hydroxypropyl)-α-cyclodextrin (hpCD) and polyethylene glycol (PEG), with well-defined hpCD threading ratios controllable across a wide range from 0.64% to 10%. In hpCD/PEG aqueous solutions, hpCDs are well dispersed and threaded spontaneously into hpCDs to form a pseudo-PR (pPR) structure. The homogeneous d ...

Abstract:
... Covalent organic frameworks (COFs), as an emerging crystalline porous material, have drawn considerable attention in many fields. Therefore, facile preparations of COFs using green and mild methods are necessary and worthwhile goals. In this study, four COFs with different morphologies were successfully synthesized by adopting 1,3,5-tris(4-aminophenyl)benzene (TAPB) and 2,5-dimethoxybenzene-1,4-di ...

Abstract:
... The demand for high safety lithium batteries has led to the rapid development of solid electrolytes. However, some inherent limitations of solid polymer electrolytes (SPEs) impede them achieving commercial value. In this work, a novel polyethylene oxide (PEO)-based solid electrolyte is reported. For the first time, biomaterial-based chitosan-silica (CS) hybrid particles serve as fillers, which can ...

Abstract:
... Promising sulfurized polyethylene glycol (SPEG) composite cathodes with a high-rate capability over 3000 mA g⁻¹ at 393 K are fabricated for Al metal anode rechargeable batteries with a 61.0–26.0–13.0 mol% AlCl₃–NaCl–KCl inorganic ionic liquid electrolyte. The combination of the SPEG composite cathodes and chloroaluminate inorganic IL can readily enhance the performance of the Al–S batteries, e.g., ...

Abstract:
... We investigate the degradation behaviour of a triblock-copolymer surfactant made from polyethylene oxide (PEO) and polypropylene oxide (PPO) (PEO-PPO-PEO), highlighting how the aggregation behaviour of this polymer in water alters with ageing. Samples aged at room temperature were compared to samples degraded using accelerated ageing at elevated temperatures. We find that large mass losses occurre ...

Abstract:
... In this work, a model of adhesion formation in mice was optimized. It was shown that there were no significant differences in the level of adhesion between mouse strains (CD1, CBA, BALB/c, C57BL/6) and that the adhesion formed within 24 h after surgery and persisted for a long time. A comparative analysis of the effectiveness of materials based on carboxymethylchitosan (CMCh) and carboxymethylcell ...

Abstract:
... Understanding shear thickening fluids (STFs) is critically important in a broad spectrum of fields ranging from biology to military. STFs are referred to the suspension of solid particles in an inert carrier liquid. Customizing the thickening behavior is vital for obtaining desired properties. Hence, comprehending shear thickening mechanisms is necessary to fully understand the factors affecting t ...

Abstract:
... Covalent adaptive networks combine the advantages of cross-linked elastomers and dynamic bonding in a single system. In this work, we demonstrate a simple one-pot method to prepare thiol–ene elastomers that exhibit reversible photoinduced switching from an elastomeric gel to fluid state. This behavior can be generalized to thiol–ene cross-linked elastomers composed of different backbone chemistrie ...

Abstract:
... Photothermal therapy (PTT) has been widely employed in tumor treatment due to the non-invasive, highly selective, and low toxic side effects. However, the limited penetration of laser couples with the metastasis and recurrence of tumors, thus failing to eliminate them. Here, we report that ceria-loaded gold@platinum (CeO₂/Au@Pt) nanospheres modified with polyethylene glycol (PEG). exhibit dual enz ...
