Covalently Cross‐Linked Pig Gastric Mucin Hydrogels Prepared by Radical‐Based Chain‐Growth and Thiol‐ene Mechanisms

Macromolecular Bioscience, Volume 22, Issue 4, April 2022., 2022
This study introduces acrylate‐ and allyl‐ether‐modified pig gastric mucin for the preparation of chemically cross‐linked hydrogels through free‐radical polymerization and thiol‐ene coupling with thiol‐modified hyaluronic acid, respectively. The data show that these hydrogels are cytocompatible and exhibit an adaptable stiffness in the range of soft ...

Reflectometry for Wendelstein 7-X [PDF]

Nuclear Fusion, 2006
Diagnostic equipment for the fully optimized stellarator Wendelstein 7-X involves a reflectometry system dedicated to measuring edge density profiles and characterizing density perturbations and their poloidal propagation velocity. Preparatory work such as design activities and the installation of a first antenna pair belongs to the so-called start-up ...

Heterogeneous design and mechanical analysis of HELIAS 5‐B helium‐cooled pebble bed breeding blanket concept

International Journal of Energy Research, Volume 46, Issue 3, Page 2748-2770, 10 March 2022., 2022
Summary One of the most challenging objectives of the European research concerning nuclear fusion technology, promoted by the EUROfusion consortium, is to bring stellarator‐type nuclear fusion devices to maturity. To this purpose, studies on a large HELIcal‐axis advanced stellarator (HELIAS), extrapolated from Wendelstein 7‐X and based on a 5‐fold ...

How well can today's tooth‐colored dental restorative materials reproduce the autofluorescence of human teeth? – Ambition and reality!

Journal of Esthetic and Restorative Dentistry, Volume 33, Issue 5, Page 720-738, July 2021., 2021
Abstract Objectives The autofluorescence of dental hard tissues has been known for over 100 years. Thus, manufacturers add fluorophores to dental restorative materials to improve the esthetic properties of these materials. So far, there has been no study evaluating the ability of these fluorophores to reproduce the autofluorescence of dental hard ...

Sphingolipid long‐chain base hydroxylation influences plant growth and callose deposition in Physcomitrium patens

New Phytologist, Volume 231, Issue 1, Page 297-314, July 2021., 2021
Summary Sphingolipids are enriched in microdomains in the plant plasma membrane (PM). Hydroxyl groups in the characteristic long‐chain base (LCB) moiety might be essential for the interaction between sphingolipids and sterols during microdomain formation.

A newcomer: the Wendelstein 7-X Stellarator [PDF]

Europhysics News, 2016
T his development has led to the large “Model-C” stellarator, operated at PPPL from 1961-1969 until it was converted into the “Symmetric Tokamak” in 1970, after breakthrough results reported from Russian tokamaks in 1968. The first “Wendelstein” stellarator, the “1-A” went into operation in 1960 at the Max-Planck Institute for Physics and Astrophysics.
