We present an investigation into incorporating core-shell Au-SiO(2) nanoparticles dye-sensitized solar cells. demonstrate plasmon-enhanced light absorption, photocurrent, and efficiency for both iodide/triiodide electrolyte based solid-state Our spectroscopic indicates that photocarrier generation competes well with plasmons oscillation damping in the first tens of femtoseconds following absorption.
Mesoporous nanomaterials have attracted widespread interest because of their structural versatility for applications including catalysis, separation, and nanomedicine. We report a one-pot synthesis method class mesoporous silica nanoparticles (MSNs) containing both cubic hexagonally structured compartments within one particle. These multicompartment MSNs (mc-MSNs) consist core with cage-like morphology up to four branches packed cylindrical mesopores epitaxially growing out the vertices. The...
Mesoporous silica with cubic symmetry has attracted interest from researchers for some time. Here, we present the room temperature synthesis of mesoporous nanoparticles possessing Pm3̅n very high molar ratios (>50%) 3-aminopropyl triethoxysilane. The is robust allowing, example, co-condensation organic dyes without loss structure. By means pore expander molecules, size can be enlarged 2.7 to 5 nm, while particle decreases. Adding and co-condensing fluorescent in same reduces average further...
This work reports on the structural evolution during room temperature synthesis of hexagonally ordered mesoporous silica nanoparticles with and without embedded iron oxide particles. Oleic acid-capped are synthesized transferred to an aqueous phase using cationic surfactant, hexadecyltrimethylammonium bromide (CTAB). MCM-41 type composite fabricated via sol–gel synthesis. Aliquots taken from solution capture particle formation process. Transmission Electron Microscopy (TEM) Small Angle X-ray...
We report the room temperature formation of aminated mesoporous silica nanoparticles (NH2-MSNs) by means co-condensation different molar ratios tetraethyl orthosilicate (TEOS) and 3-aminopropyl triethoxysilane (APTES) in synthesis feed. The resulting materials are characterized a combination transmission electron microscopy (TEM), small-angle X-ray scattering (SAXS), Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), N2 adsorption/desorption measurements....
Mesoporous silica nanoparticles have highly versatile structural properties that are suitable for a plethora of applications including catalysis, separation, and nanotherapeutics. We report one-pot synthesis strategy generates bimodal mesoporous via coassembly structure-directing Gemini surfactant (C16-3-16) with tetraethoxysilane/(3-aminopropyl)triethoxysilane-derived sol additive. Synthesis temperature enables control the nanoparticle shape, structure, mesopore architecture. Variations...
Zinc oxide polymeric nanoparticles (ZPPs) of poly (styrene-co-acrylic acid) P(St/AA), containing oleic acid modified zinc (OA-ZnO NPs), were synthesized via miniemulsion polymerization. By simply adjusting the quantity reactants, i.e., sodium dodecyl sulfate (SDS) surfactant, potassium persulfate (KPS) initiator, and divinyl benzene (DVB) crosslinking agent, location ZnO NPs altered from inner (core) to outer (shell), leading core-shell Pickering-like morphologies, respectively. The ZPPs...
Abstract Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common enzymopathy in humans, affecting ~ 500 million worldwide. A detailed study of structural stability and catalytic activity G6PD variants required to understand how different mutations cause varying degrees enzyme deficiency, reflecting response oxidative stress. Furthermore, for double variants, investigating two jointly severe important. Here, we characterized functional properties nine variants: Gaohe, Mahidol,...
