Reductive alkylation of acrylonitriles and acrylates

, 1974
In the presence of activated metals , secondary alkyl iodides and bromides react with olefins conjugated with electron withdrawing groups, in particular acrylonitriles and acrylates, to give the corresponding product (III) of reductive ...

Reducing Interfacial Separation Force in High‐Speed Constrained‐Surface Projection Stereolithography Using a Dual‐Modulus Silicone Release Film

Advanced Materials Interfaces, EarlyView.
A dual‐modulus silicone release film creates distributed stress concentrations at high‐/low‐modulus boundaries, triggering multi‐site crack initiation and rapid interfacial detachment. The architecture lowers the peak separation force by 97.6%, shortens detachment time, and enables stable continuous projection stereolithography at 720 mm h−1, offering ...

A convenient synthesis of λ-oxo-acrylates

, 1988
Ethyl 2,4-dioxoalkanoates react chemoselectively with pyrrolidine acetate at the more electrophilic C-2 carbonyl, producing enaminone esters which on reduction with NaCNBH4 followed by pyrrolidine elimination, were transformed into γ-oxo-acrylates ...

A Critical Review on the Evolution of Chitosan‐Based Injectable Hydrogels in Bone Regeneration

Advanced Materials Interfaces, EarlyView.
The graphical illustration depicts hydrogel formulation using chitosan and biocompatible cross‐linkers, major advantages, and incorporation of cells, osteoinductive factors, and therapeutic drugs. Following injection, pH‐responsive gelation enables controlled drug release, promotes cell recruitment and osteogenic differentiation, enhances extracellular

Hybrid Additive Manufacturing of Highly Stretchable Bottlebrush Polymer Nanocomposites by Decoupled Extrusion and Photopatterning

Advanced Materials Technologies, EarlyView.
A Hybrid Direct Ink Writing–Digital Light Processing (HDD) strategy decouples material extrusion from shape definition, enabling high‐fidelity additive manufacturing of highly viscous, yield‐stress polymer nanocomposites. Excess ink acts as a removable, self‐supporting scaffold, allowing fabrication of unsupported and embedded complex architectures ...

Determination of Propagation Rate Coefficients of a Family of Acrylates with PLP‐MALDI‐ToF‐MS

, 2010
The combination of MALDI-ToF-MS with pulsed laser polymerization (PLP) has one big advantage over the combination of size exclusion chromatography (SEC) with PLP. MALDI-ToF-MS is an absolute measurement which does not need calibration.

Aerosol Jet Printing of Benzocyclobutene as a Thermally Stable, Low‐Loss Dielectric for Multilayer Microwave Electronics

Advanced Materials Technologies, EarlyView.
Multilayer aerosol jet printed components with a low‐loss, thermally stable dielectric are demonstrated using benzocyclobutene. Ink formulation and in‐line droplet evaporation control support high‐quality, versatile, and stable printing performance. A specialized measurement for low‐loss materials reveals promising microwave properties, which, combined
