Properties of electrical tree resistance of silicone‐modified epoxy resin matrix composites
IET Science, Measurement & Technology, 2023 In order to improve the electrical tree resistance of epoxy resin, composites were prepared using dihydroxydiphenylsilane and a novel silicone modifier modified epoxy resin and micron silica, and the composites were subjected to accelerated thermal aging

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions
FEBS Letters, EarlyView.The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

NEW RESTORATION AND DIRECT PULP CAPPING SYSTEMS USING ADHESIVE COMPOSITE RESIN [PDF]
, 1991 There have been many arguments on the irritating mechanisms of the composite resin on the dental pulp. While the direct irritative effect of the resin has been prefered, some authors considered that the marginal microleakage and the resulting bacterial ...

Translophagy—A potential link between autophagy impairment and translational errors
FEBS Letters, EarlyView.Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Electric-field structuring of piezoelectric composite materials [PDF]
, 1999 Piezoelectric composite materials, consisting of a ferroelectric ceramic in an electrically-inactive polymer matrix, have been shown to greatly outperform single phase materials for certain applications.

The Effect of Espresso and Drip Brewing Coffee Methode to The Hardness of Bulk-Fill Composite Resin
Jurnal Kedokteran Diponegoro, 2022 Background: The most restoration material used currently in dentistry was composite resin. The newest generation of composite resin was bulk-fill composite resin. The bulk-fill composite resin had advantages of lower polymerization contraction and a more

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Shear bond strength of ceramic brackets to resin-composite surfaces
Australasian Orthodontic Journal, 1997 In this study, two types of ceramic brackets – monocrystalline and polycrystalline – were bonded to unroughened and roughened resin-composite discs using a light-cured orthodontic adhesive, and the bonds tested under shear stress in a universal testing ...
