Hyperbranched Interpenetrating Hydrogen Bond Network (HIHBN) Proton Exchange Membrane for Fuel Cells Above 220 °C

open access: yesAdvanced Functional Materials, EarlyView.
A novel polymer electrolyte membrane with a hyperbranched interpenetrating hydrogen bond network structure is developed. The unique structure of the hyperbranched polymer contributes to a high glass transition temperature exceeding 400 °C, enabling its operation at elevated temperatures for fuel cell applications.

A NEW METHOD OF DETERMINATION OF CALCIUM ORTHOPHOSPHATE AND ASSOCIATED IMPURITIES BY THERMOGRAVIMETRY AND DERIVATIVE THERMOGRAVIMETRY

open access: yesJournal of Food Quality, 1979
ABSTRACTCalcium orthophosphte (TCP) is known to be a nutritional additive in processed foods and wheat flour. Only pure salt is highly toxic to stored product insects. However, commercial salts were found to contain other monobasic and dibasic calcium phosphates and carbonates of calcium and magnesium which reduce insecticidal potency and affect food ...

Solution‐Processable and Ambient‐Stable Highly Conductive p‐Type Polymers Derived from Dihydropyrazine and Ethylenedioxythiophene

open access: yesAdvanced Functional Materials, EarlyView.
This work presents π–conjugated polymers based on dihydropyrazine (DHP) and ethylenedioxythiophene (EDOT), developed to produce highly conductive, flexible films for printed electronics. By optimizing the DHP and EDOT ratio, strong and compact π–π stacking is achieved, resulting in polymer films with conductivities up to 1700 S cm−1 under ambient ...

A Strong and Water‐Retaining Biomass Adhesive Inspired by Tofu

open access: yesAdvanced Functional Materials, EarlyView.
Drawing inspiration from the formation mechanism of the traditional food tofu, a strong and water‐retaining adhesive is designed using the soybean meal (SM) oxidized by glucose oxidase (GOx) and calcium sulfate oligomer (CSO). This design strategy effectively addresses the conflicting requirements of water‐resistant bonding strength and water retention
