Lithography-based additive manufacturing technologies have become a valuable tool in tissue engineering for the fabrication of biocompatible and biodegradable bone regeneration scaffolds. Currently employed photopolymers based on (meth)acrylates, vinyl esters, or carbonates display undesirable properties such as irritancy cytotoxicity residual monomers, degradation via autocatalytic bulk erosio...

Reaction of ethyl (Z)-3-(heteroaryl/aryl)-2-((triphenyl-λ5-phosphaneylidene) amino) acrylates intermediates with 2,3-thiophenedicarboxaldehyde was used in novel Tandem three consecutive reactions: aza-Wittig, imine condensation and electrophilic heteroaromatic cyclization to obtain a series indolizines. A tentative mechanism this reaction is proposed.

The demand for optical components such as microlenses has been growing at a rapid rate in recent years. While conventional methods manufacturing these are well known, they often time-consuming, detrimental the environment and unable to keep up with increasing demand. To overcome issues, technique of three-dimensional (3D) inkjet printing attracted much attention. aim this review was investigate...

Abstract Various copolymers incorporated with β-substituted acrylates, such as alkyl crotonates (e.g., methyl crotonate (MC), ethyl (EC), isopropyl (iPC), and n -butyl (nBC)) cinnamate (MCin), were synthesized by group-transfer polymerization (GTP) using a silicon-based Lewis acid catalyst. In addition to α-substituted acrylates methacrylate (MMA) (nBMA)) examined comonomers. Proton nuclear mag...

In order to improve the performance of allyl starch-g-poly(acrylic acid-co-acrylate) sizes, effect of molecular structure of the acrylate monomers grafted onto allyl starch has been studied. A series of acrylates including methyl acrylate (MA), ethyl acrylate (EA), butyl acrylate (BA) and 2-ethylhexyl acrylate (EHA) have been grafted onto allyl starch with the same degree of substitution throug...

In dentistry, allergic contact dermatitis to acrylates and allergic contact urticaria to latex are important occupational hazards. There is a need to identify non-latex gloves which are suitable for dental work but at the same time provide adequate protection against acrylate monomers. In a previous study, a new open-chamber system was used for testing the in vivo protection of 6 different glov...
