The research progress in polyethylene oxide polymer electrolytes

open access: yesFlexMat, EarlyView.
Polyethylene oxide (PEO) has become the mainstream matrix material for solid polymer electrolytes (SPEs) due to its excellent lithium salt complexation ability and processability. However, its high crystallinity results in low ionic conductivity at room temperature and difficulty in suppressing lithium dendrite growth, which significantly hinders the ...

Flexible organic electrodes for batteries: A mini‐review

open access: yesFlexMat, EarlyView.
This review surveys progress and challenges in flexible organic electrodes (FOEs) for batteries. We discuss their fabrication methods, electrochemical performance, and mechanical tolerance, covering both planar and fibrous architectures, and compare them with flexible inorganic and rigid organic electrodes.

Methodological guidelines for the characterization of polysaccharide helical structures

open access: yesFood Biomacromolecules, EarlyView.
Abstract Polysaccharide chain conformation is a critical determinant of their physicochemical and biological properties; however, reliable identification remains a significant challenge due to the inconsistent structural evidence yielded by conventional analytical techniques.

Local Structures of Se and Br in Cretaceous–Paleogene Boundary Sediments and Concentration Effects of Ferrihydrite Originating From Impact Ejecta

open access: yesGeological Journal, EarlyView.
Chemical states of Se and Br atoms in the KPg boundary sediments from Stevns Klint were studied using XAFS spectroscopy. The high concentrations of Se4+ could become an index of the degree to which the global environment was soiled with dust and ash derived from impact ejecta or volcanic eruptions.

Association between maternal pre‐pregnancy body mass index and maternal and neonatal outcomes in Saudi Arabia: A retrospective cohort study

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective The body mass index (BMI, calculated as weight in kilograms divided by the square of height in meters) of the mother before pregnancy and the growth of weight during pregnancy are both important perinatal health determinants. The aim of the present study was to examine the association between the maternal BMI and obstetric and ...
