Highly Tunable Thermal Properties of Multifunctional Thiol‐Ene Networks Derived From Sugar‐Based Monomers

Journal of Polymer Science, EarlyView.
Eleven allylated sugar frameworks combined with seven dithiol compounds create 77 thiol‐ene networks with a wide range of thermomechanical properties. Analysis based on composition reveals that both the sugar's functionality and the scaffold's structure work in conjunction with dithiol chemistry to influence the rubbery modulus, glass‐transition ...

Analysis of diffractive optical elements generated onto photopolymer materials using a liquid crystal display [PDF]

, 2012
We produce phase-only diffractive optical elements (DOE) onto photopolymer. To this goal we use a liquid crystal display (LCD), displaying the DOE amplitude master, which is imaged onto the photopolymer.

Development of a Gingiva Model With Periosteum for Dental Students Using 3D Printing Compared to Knowledge‐Related Models

European Journal of Dental Education, EarlyView.
ABSTRACT Introduction An adequate gingiva model for dental students has special requirements, such as strength, flexibility and a periosteum. As there is a lack of available models, the aim of this study was to develop a new and sufficient gingiva model that fits students' needs.
