Programmable Carrier‐Free All‐Enzyme Beads for Modular Continuous‐Flow Biocatalysis

open access: yesAdvanced Materials, EarlyView.
Genetically encoded enzyme building blocks self‐assemble into monodisperse, carrier‐free protein beads via a droplet‐based formulation strategy. These programmable catalytic particles enable modular continuous‐flow biocatalysis, from single‐enzyme reactions to multi‐enzyme cascades and bead–bead coupled reactor systems.

Stability, Content of Bioactive Compounds and Antioxidant Activity of Emulsions with Propolis Extracts during Simulated In Vitro Digestion

open access: yesFoods
The objective in this work was the evaluation of the stability and content of bioactive compounds (total phenols and total flavonoids) and antioxidant activity of emulsions of ethanolic extracts of propolis obtained by ultrasound, during simulated in ...

TOTAL ANTIOXIDANT CAPACITY AND TOTAL PHENOL CONTENTS OF SELECTED

open access: yes, 2010
The in vitro total antioxidant capacity (TAC), and the total phenol (TP) contents of commercial fruit juice samples widely consumed in Turkey were determined. TAC methods were more recently developed methods (TAC(1) and TAC(2)) using Fe(+2)-o-dianisidine complex and ABTS radical, FRAP (Ferric Reducing Ability of Plasma) method (TAC(3)). Folin Ciocalteu

Biohybrid Crawling Robot With Spiral‐Spring Backbone and Inclined Legs for Enhanced Locomotion

open access: yesAdvanced Materials, EarlyView.
We present a biohybrid crawling robot integrating a muscle ring with a flexible skeleton combining two complementary structural elements. The spiral‐spring backbone enables large‐amplitude bending without compromising axial stability, while outward‐inclined legs with unequal front–rear lengths effectively convert deformation into directional strides ...

Total Antioxidant, Phenolic Compounds, and Total Oxidant Status of

open access: yes, 2009
In this study, total oxidant status (TOS), total antioxidant capacity (TAC), and total phenols (TP) of seventeen certified and eight uncertified honey samples were analyzed. The TAC and TOS of the samples were determined using novel methods. Uncertified honey samples had significantly lower values for their TP, TAC, and TOS contents than those of ...

Strong Fully Reprocessable Engineered Wood Composites

open access: yesAdvanced Materials, EarlyView.
Engineering a hyperbranched adhesive with complementary imine‐bond and hydrogen‐bond networks, combining it with wood particles to fabricate the wood composite (WP/HTP) under mild hot‐pressing conditions. The WP/HTP exhibits 100% mechanical strength recovery after three cycles of reprocessing, and the reprocessed modulus of rupture (MOR) and modulus of

Methanesulfonic Acid as a Dual‐Role Reagent for Porous Polymer Network Design

open access: yesAdvanced Materials, EarlyView.
The design of porous polymer networks (PPNs) using methanesulfonic acid (MSA) as a dual‐role reagent facilitates the synthesis of robust PPNs for specific applications. It also makes the scale‐up process techno‐economically feasible because MSA functions simultaneously as both a solvent and a catalyst for the reaction.
