Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies

open access: yesAdvanced Engineering Materials, EarlyView.
Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...

Novel Tailoring of Ternary ZnS‐MXene‐TiO2 Nanocomposite Heterojunction and Its Tunable Electrochemical Properties With Enhanced Photocatalytic Degradation

open access: yesAdvanced Engineering Materials, EarlyView.
ZnS‐MXene‐TiO2 nanocomposite heterojunction for photocatalytic decomposition of this methylene blue dye (MB) greatly improves light absorption, charge separation, and active site area. Two‐dimensional MXene forms nanocomposites by easily combining them with 0D (quantum dots), 1D (tube and wire), 2D (plane and sheet), and 3D (particle and lamellar ...

Biological Ion Exchanger Resins

open access: yesBiophysical Journal, 1971
ABsrRACT Utilizing Escherichia coli as the prototype of an ion-accumulating cell, the ion exchange isotherm is introduced as a concise method of characterizing biological ion exchange events. The ion exchange isotherm for the alkali cation exchange, K 4-> Na, is described. The total charge proffle of this bacterium is compiled and compared for bacteria
