The present review article summarizes the recent findings reported in literature with regard to use of molecularly imprinted polymers for removal arsenic from water and wastewater. MIPs are which a template is employed order enable formation recognition sites during covalent assembly bulk phase, via polymerization or polycondensation process. efficiency both species mechanism highlighted. resul...

The simultaneous polymerization and crystallization of monomers featuring directional bonding designs provides covalent organic frameworks (COFs), which are periodic polymer networks with robust covalent bonds arranged in two- or three-dimensional topologies. The range of properties characterized in COFs has rapidly expanded to include those of interest for heterogeneous catalysis, energy stora...

The prediction of the existence and the structure of previously unknown solid-state compounds seems to be par­ ticularly difficult, because numerous complex, interacting factors must be taken into account. A simplification to a certain extent is possible with predominantly covalent poly­ meric solid-state compounds in which coordination numbers and geometries are unambiguously stipulated for th...

The recent progress of research on polymer reactions utilizing dynamic covalent exchanges of alkoxyamine units—adducts of styryl and stable nitroxide radicals—is reviewed. The alkoxyamine derivatives derived from 2,2,6,6-tetramethylpiperidine-1-oxy (TEMPO, a stable free radical) are frequently utilized as unimolecular initiators for the nitroxide-mediated radical polymerizations. In the absence...

Abstract Dynamic covalent polymers have gained more and attention for their fascinating dynamic features broad application prospects. As an emerging powerful synthetic tool, X‐yne click polymerization, mainly including thiol‐yne, amino‐yne hydroxyl‐yne polymerizations, has been rapidly developed widely applied in the preparation of functional recent years. Moreover, exchange processes successiv...

Novel mesoscopic organic nanosheets were developed by functionalizing bulk 2D organic covalent framework polymers with small molecules. The water-soluble fluorescent nanosheets are promising as nanocarriers for biological applications.

A mercapto derivative of diacetylene was used as the hydrophilic ligand to prepare Janus nanoparticles by using hydrophobic hexanethiolate-protected gold (AuC6, diameter 5 nm) nanoparticles as the starting materials. The amphiphilic surface characters of the Janus nanoparticles were verified by contact angle measurements, as compared to those of the bulk-exchange counterparts where the two type...

The covalent incorporation of functional groups-specifically sulfoxide and sulfone-into the cation of imidazolium ionic liquids leads to significant, quantifiable changes in solvent parameters which in turn have important effects on the bulk properties of the materials.

This study evaluated the effects of fiber nets and application techniques and flowable composites as a liner on microleakage and the effects of fiber nets on polymerization shrinkage in Class II MOD cavities. Standard MOD cavities were performed in 80 extracted third molars. The teeth were randomly divided into eight groups (n=10). Group 1: Filtek Supreme XT (bulk technique) (FSB); Group 2: Fil...
