Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

open access: yesAdvanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

MOF‐Derived Transition Metal Carbide@Electroactive Polypyrrole Nanohybrid‐Based High‐Performance and Stretchable Multimodal Patch for Perspiration Analysis

open access: yesAdvanced Functional Materials, EarlyView.
A high‐performance stretchable multimodal sweat‐sensing patch is developed by integrating a MOF‐derived molybdenum carbide nano‐octahedron/polypyrrole (MoCx‐Oct@PPy) nanohybrid onto SEBS‐transferred laser‐engraved graphene electrodes. The nanohybrid‐based patch incorporates four sensors for the monitoring of glucose, vitamin C, Na+, and pH in sweat ...

Porous Copolymer Resins: Tuning Pore Structure and Surface Area with Non Reactive Porogens

open access: yesNanomaterials, 2012
In this review, the preparation of porous copolymer resin (PCR) materials via suspension polymerization with variable properties are described by tuning the polymerization reaction, using solvents which act as porogens, to yield microporous, mesoporous ...

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Electrostatic Superlattices Beyond 1:1 Stoichiometry

open access: yesAdvanced Functional Materials, EarlyView.
Polymer‐mediated charge regulation drives two hierarchical routes to higher‐stoichiometry nanoparticle superlattices. Tuning the polymer's molecular weight promotes progressive interstitial filling, transforming ZnS into the fully occupied CaF2${\rm CaF}_2$ lattice. Exchanging polymer assignment between large and small nanoparticles instead breaks CsCl

Protein nanoreactors and native enzymes for controlled/living radical polymerization [PDF]

open access: yes, 2013
The present PhD thesis entitled ‚Protein Nanoreactors and Native Enzymes for Controlled/Living Radical Polymerization‘ began with the hypothesis that protein-catalyst conjugates are able to beneficially influence controlled/living radical polymerization,

Preparation and Characteristics of Polystyrene/Attapulgite Composites Via In-siu Suspension Polymerization

open access: yesMATEC Web of Conferences, 2016
A series of polystyrene/attapulgite composites were synthesized through suspension polymerization. The composites were characterized by Fourier transform infrared spectroscopy, thermal gravimetric analysis, and X-ray diffraction.

Capillary Suspensions with Polymeric Bridges

open access: yes, 2019
Poröse Materialien werden in einem breiten Anwendungsbereich eingesetzt, wie in der Trenn- und Filtertechnik, sowie als Wärmedämmstoff oder katalytische Materialien je nach ihrer Porengröße. Diese porösen Materialien werden nach ihrer Porosität, d.h. dem Verhältnis des Hohlraumvolumens zum Gesamtvolumen des Materials, klassifiziert.
