Objectives: This study evaluated the effects of delayed post-polymerization on color, degree of conversion (DC), flexural strength (FS), and cellular response of a 3D-printed dental interim resin. Methods: Specimens were divided into six groups based on delays of 0 h, 2 h, 4 h, 6 h, 8 h, and 10 h before post-polymerization. Color was characterized using ...

Anion exchange ionomer (AEI) binders are critical to the performance of alkaline electrochemical devices (i.e., fuel cells, electrolyzers, and batteries), as they facilitate ion transport, provide structural integrity, and improve the overall performance and lifespan of these devices. These binders not only ensure ion transport but also provide mechanical ...

Sulfur autotrophic denitrification (SAD) offers a sustainable solution for nitrogen removal in low carbon to nitrogen ratio (C/N) municipal wastewater, yet its efficiency and startup time pose significant challenges. To overcome these, we developed iron-sulfur-modified carriers (FeS@MC) and integrated them into an in-situ sequencing batch reactor (S-Fe-SB ...

Well-defined acid-degradable amphiphilic block copolymers (ABPs) and their nanoassemblies labeled with acid-labile groups have been developed for smart drug delivery, exhibiting controlled/enhanced release of therapeutics in tumoral tissues and endo/lysosomes. In general, controlled polymerization techniques, particularly atom transfer radical polymerizat ...

Polydimethylsiloxane (PDMS) and poly(3,4-ethylene dioxythiophene):poly(4-styrene-sulfonate) (PEDOT:PSS) composites were tested to determine their suitability for charging small-scale batteries in conjunction with a piezoelectric actuator as an energy harvester. Two different PEDOT:PSS patterns (zigzag and serpentine) were tested, and the maximum DC voltag ...

Ionomers containing a small number of ionic side groups are a unique class of polymers with some valuable properties and distinct applications. To date, commercially important ionomers are exclusively anionomers that contain covalently bonded anions and are synthesized commonly by radical polymerization. The catalytic synthesis of polyethylene-based catio ...

The ring-opening polymerization of bio-based monomer 2-methylene-1,3-dioxepane (MDO) can reportedly enhance polymer degradability. Butyl acrylate (BA)/MDO/vinyl acetate (VAc) terpolymers were synthesized via emulsion polymerization for their eventual application as pressure-sensitive adhesives (PSAs). While using MDO in emulsion polymerization leads to a ...

Biosensing technology, which aims to measure and control the signals of biological substances, has recently been developed rapidly due to increasing concerns about health and the environment. Top-down technologies have been used mainly with a focus on reducing the size of biomaterials to the nano-level. However, bottom-up technologies such as self-assembl ...

Ozone is a hazardous air pollutant with significant adverse effects on human health and the environment. With the growing industrial use of ozone, effective ozone removal systems have become essential, especially to protect workers' health. MnOx-based catalysts offer substantial promise for ozone decomposition; however, a major challenge in their appl ...

This investigation introduces the first estimation of ternary reactivity ratios for a butyl acrylate (BA), 2-methylene-1,3-dioxepane (MDO), and vinyl acetate (VAc) system at 50 °C, with an aim to develop biodegradable pressure-sensitive adhesives (PSAs). In this study, we applied the error-in-variables model (EVM) to estimate reactivity ratios. The ternar ...
