This study reports a synthetic polymer functionalized with catechol groups as dental adhesives. We hypothesize that a catechol-functionalized polymer functions as a dental adhesive for wet dentin surfaces, potentially eliminating the complications associated with saliva contamination. We prepared a random copolymer containing catechol and methoxyethyl groups in the side chains. The mechanical a...

Abstract The high demand for an efficient energy supply various applications facilitates the development of innovative storage technologies like all‐solid‐state batteries in addition to novel production technologies. Compared conventional manufacturing process, additive (AM) is a promising technology used rapid and cost‐effective battery components containing separators. However, AM laser‐based...

The methodology and measurement results of the machine part produced directly from 3D-CAD numerical model are presented. Representative additive techniques based on polymer processing were used. accuracy replication CAD models was assessed in terms both external surface analysis volume.

Iron-filled magnetorheological polymers, when cured in the presence of a magnetic field, result in having a transversely isotropic structure with iron particles forming chains along the direction of applied magnetic induction. In this work, we model the magneto-viscoelastic deformation (and magnetization) process of such polymers. Components of the deformation gradient and the applied magnetic ...

the role of polymeric additives such as pvp and peg is studied with respect to the morphology of pes porous layer as a sublayer of nanofiltration composite membranes based on pes/pa. results show that by phase inversionprocess of quaternary systems comprised of four components of polymer/solvent/non-solvent/additive and the diffusion of intertwined polymers some changes occur in membrane morpho...

Abstract A series of sulfated aluminum oxides (S-Al 2 O 3 ), investigated as an electrolyte additive in Nafion membranes, was synthesized via three different methods: (i) sol–gel sulfation starting from alkoxide precursor, (ii) room temperature fumed oxide, and (iii) hydrothermal oxide. Through the characterization S-Al by means X-ray diffraction (XRD), thermogravimetric analysis (TGA), infrare...

The present manuscript offers an overview of the current state of affairs within the research field of adaptive and environmentally sensitive polymer surfaces designed to respond to external stimuli in a controlled and predictable manner. Intensive study in the field of the adaptive/responsive surfaces began several decades ago in an attempt to understand relationships between bulk properties/c...

In conjunction with America Makes, the nation’s leading and collaborative partner in additive manufacturing (AM) and 3D printing technology and the Manufacturing Extension Partnership (MEP) of the National Institute of Standards and Technology (NIST), Penn State’s Center for Innovative Materials Processing through Direct Digital Deposition is sending an open invitation to Small to Medium Enterp...
