A systematic study on the synergistic effects of MWCNTs and core–shell particles on the physicomechanical properties of epoxy resin

Scientific Reports, 2021
Here, core–shell impact modifier particles (CSIMPs) and multiwalled carbon nanotubes (MWCNs) were used as reinforcing agents for improving the toughness and tensile properties of epoxy resin.

A release of potentially toxic components from the acrylic resins for soft relining dentures [PDF]

Acta Stomatologica Naissi, 2019
Introduction: Soft acrylic resins belong to a group of cold curing materials that are applied to the basal surface of the dental prosthesis in order to eliminate mechanical irritation, and to allow for the recovery of damaged or inflamed mucous membranes,

On‐Demand Deconstructable Thermosets Through Cleavable Comonomer and Thermolatent Base Synergy

Angewandte Chemie, EarlyView.
Thermosets, valued for their chemical and mechanical properties, resist recycling due to their cross‐linked structure. Weak bonds via comonomers enable degradability, but diffusion limits effectiveness. We incorporate thermolatent bases before polymerization (thermal or 3D‐VAT printing).

Synthesis and Thermal Properties of Polyurethane, Poly(butyl methacrylate), and Poly(methylmethacrylate) Multi-Component IPN’s [PDF]

Polymer Journal, 1984
Three component interpenetrating polymer networks (IPN’s) of polyurethane (PU)–poly(n-butyl methacrylate) (PBMA)–poly(methyl methacrylate) (PMMA) were prepared by the combined synthesis of simultaneous polymerization and sequential polymerization.

Bottlebrush Polyolefin Sulfones as Triggerable and Degradable Pressure‐Sensitive Adhesives

Angewandte Chemie, EarlyView.
A grafting‐through alternating copolymerization strategy yields poly(norbornene sulfone) bottlebrush polymers with high molar mass. These materials function as additive‐free pressure‐sensitive adhesives. The incorporation of cleavable sulfone units enables rapid breakdown under mild alkaline conditions, providing a pathway toward sustainable, high ...

Integration of Low‐Voltage Nanoscale MoS2 Memristors on CMOS Microchips

Advanced Functional Materials, EarlyView.
This article presents the first monolithic integration of nanoscale MoS2‐based memristors into the back‐end‐of‐line of foundry‐fabricated CMOS microchips in a one‐transistor‐one‐resistor (1T1R) architecture. The MoS2‐based 1T1R cells exhibit forming‐free, nonvolatile resistive switching with ultra‐low operating voltages, low cycle‐to‐cycle variability ...
