Ambient Stable Triboelectric Nanogenerator Based on Conductive Filler Modified Silicone Rubber with Gas Barrier Encapsulation for Footstep Energy Conversion

open access: yesAdvanced Science, EarlyView.
A humidity‐tolerant triboelectric nanogenerator is developed using conductive carbon black‐modified silicone rubber and a flame‐retardant gas barrier layer. The device efficiently harvests footstep energy while maintaining stable output under 30–90% RH and over 1 million cycles.

Development and Quality of Barley Husk Adhesion Correlates With Changes in Caryopsis Cuticle Biosynthesis and Composition [PDF]

open access: yes, 2019
The caryopses of barley become firmly adhered to the husk during grain development through a cuticular cementing layer on the caryopsis surface. The degree of this attachment varies among cultivars, with poor quality adhesion causing “skinning”, an ...

Zwischen Ordnung und Verwirrung: Missverständnisse in der Nomenklatur von Kohlenstoffmaterialien

open access: yesAngewandte Chemie, EarlyView.
Trotz der vielfältigen Einsatzmöglichkeiten von Kohlenstoffmaterialien führen uneinheitliche Terminologie und unzureichende Charakterisierung – insbesondere im Hinblick auf die Ordnung der zugrunde liegenden Graphenen – häufig zu Fehlinterpretationen. Der Artikel klärt Begriffe wie Graphit, graphitischer Kohlenstoff, nicht‐graphitischer Kohlenstoff und

A whole-grain cereal-rich diet increases plasma betaine, and tends to decrease total and LDL-cholesterol compared with a refined-grain diet in healthy subjects [PDF]

open access: yes, 2017
Epidemiological studies have repeatedly found that whole-grain (WG) cereal foods reduce the risk of several lifestyle-related diseases, though consistent clinical outcomes and mechanisms are elusive.

Between Order and Confusion: Clearing up Structural Misconceptions in Carbon Materials Nomenclature

open access: yesAngewandte Chemie International Edition, EarlyView.
Despite the versatile use of carbon materials, inconsistent terminology and inadequate characterization – especially regarding graphene structures based on sp2‐hybridized carbon atoms – often cause confusion. This perspective clarifies terms like graphite, graphitic carbon, non‐graphitic carbon, and amorphous carbon by aligning IUPAC definitions with X‐
