Abstract The fluorescence and photoactivity of a series of Zn and Lu phthalocyanine complexes incorporated in various polymer fibers were investigated for the phototransformation of 4‐chlorophenol, 4‐nitrophenol, and methyl orange. The phthalocyanine complexes functionalized on polystyrene and polysulfone polymer fibe…
Treatments specific to the medical problems caused by methamphetamine (METH) abuse are greatly needed. Toward this goal, we are developing new multivalent anti-METH antibody fragment-nanoparticle conjugates with customizable pharmacokinetic properties. We have designed a novel anti-METH single chain antibody fragment…
Nanocomposites based on polypropylene (PP) containing 5–15 wt% of nano-calcium carbonate (CaCO 3 ) particles and 1–3 wt% of maleated PP as compatibilizer were prepared by melt compounding followed by injection molding. The crystallinity, shrinkage behavior and mechanical properties were characterized, and the morpholo…
Supramolecular polymer nanowires have been prepared by using DNA-templating of 2,5-(bis-2-thienyl)-pyrrole (TPT) by oxidation with FeCl(3) in a mixed aqueous/organic solvent system. Despite the reduced capacity for strong hydrogen bonding in polyTPT compared to other systems, such as polypyrrole, the templating procee…
Abstract The ability to efficiently visualize protein targets in cells is a fundamental goal in biological research. Recently, quantum dots (QDots) have emerged as a powerful class of fluorescent probes for labeling membrane proteins in living cells because of breakthrough advances in QDot surface chemistry and biofun…
CaF 2 Nanoparticles (NPs) were synthesized with a co-precipitation method and used in the preparation series (Polyvinyl Alcohol (PVA)/ CaF 2 nanocomposite films) with different amounts of CaF 2 NPs. The synthesized NPs and nanocomposite films were characterized by X-ray Diffraction (XRD), Scanning Electron Microscopy…
The adsorption of insecticide, carbofuran from aqueous solution onto activated carbon derived from palm oil fronds (PFAC) was investigated through batch study. The effects of both initial concentration and pH of the carbofuran over the range of 25 to 250 mg/L and 2 to 12, respectively, on the adsorption of the prepare…
Polyacrylic acid was converted into modified polymers with the targeted functional groups through the reaction with different organic compounds such as some aromatic amines and acids. The obtained modified polymeric products have been characterized through FT-IR spectroscopic and thermal analyses. Modified acrylic pol…
Electrodeposition onto insulating polymeric films is a synthetic route for preparing sparse metallic particles with a great variety of shapes. The nucleation of zinc on the insulating polyaniline occurs at defects in the film, which have a density on the order of 10 6 cm –2 . The number and size distribution of the pa…
Three novel intumescent flame retardants (IFRs), polyphosphate esters (designated as PDP, PEP, and PPP), were synthesized by reacting phenyl dichlorophosphate with three bis-hydroxy azomethine monomers through interfacial polycondensation. The polyphosphate esters were characterized by hydrogen nuclear magnetic resona…
Plasmonic nanostructures with tunable optical properties and their designed spatial arrangements can facilitate a variety of application ranging from plasmonics to biosensors with unprecedented sensitivity. Here we describe a facile and versatile method for fabricating tunable plasmonic substrates based on the reshapi…
Electrospinning is a commonly used and versatile method to produce scaffolds (often biodegradable) for 3D tissue engineering.(1, 2, 3) Many tissues in vivo undergo biaxial distension to varying extents such as skin, bladder, pelvic floor and even the hard palate as children grow. In producing scaffolds for these purpo…
SiO2 hollow spheres and low relative permittivity insulation paper handsheets composed of these SiO2 hollow spheres with different weight percentages were successfully prepared. Low-content SiO2 hollow spheres were uniformly dispersed in the insulation paper handsheets. The relative permittivity of the immersed oil Kr…
High-spin organic molecules with dominant spin-orbit contribution to magnetic anisotropy are reported. Quintet 4-azido-3,5-dibromopyridyl-2,6-dinitrene (Q-1), quintet 2-azido-3,5-dibromopyridyl-4,6-dinitrene (Q-2), and septet 3,5-dibromopyridyl-2,4,6-trinitrene (S-1) were generated in solid argon matrices by ultraviol…
The mechanical properties and hydraulic permeabilities of biomaterial scaffolds play a crucial role in their efficacy as tissue engineering platforms, separation processors, and drug delivery vehicles. In this study, electrospun cellulose acetate fiber meshes of random orientations were created using four different co…
To understand complex micro/nanoscale ECM stem cell interactions, reproducible in vitro models are needed that can strictly recapitulate the relative content and spatial arrangement of native tissue. Additionally, whole ECM proteins are required to most accurately reflect native binding dynamics. To address this need,…
The electronic properties and optical activities of C-doped cubic SrTiO3 in perovskite structure are studied by first-principles calculation. The calculated formation energies show that the substitutional C impurity is preferentially occupied at the Ti site. For C@O, the C impurity introduces spin-polarized gap states…
The assembly of dually reactive, well-defined diblock copolymers incorporating the chemoselective/functional monomer, 4,4-dimethyl-2-vinylazlactone (VDMA) and the surface-reactive monomer glycidyl methacrylate (GMA) is examined to understand how competition between surface attachment and microphase segregation influen…
A set of supramolecular liquid crystalline networks and polymers are synthesised and analysed utilising a bis-functionalised hydrogen bond donor, a rigid bis-pyridyl species and non-mesogenic rigid polyfunctional networking agents in tetra, tri and bi functionalities. Networks utilising the shorter bisacid eliminated…
Quantum mechanical and hybrid quantum mechanical/molecular mechanical (QM/MM) cluster models have been used to investigate the energetics of (i) B atom and BH radical insertion reactions into surface C–H and C–C bonds during chemical vapor deposition (CVD) of B-doped diamond and (ii) BH group migration on the C{100}:H…
