A nanostructured silicon/porous carbon spherical composite was prepared by a simple hydrothermal method using glucose as a carbon source and Pluronic F127 as a soft template/pore forming agent in the presence of silicon nanoparticles, and a subsequent carbonization process. In this composite, silicon nanoparticles wer…
Physical chemistry, materials science, analytical chemistry and engineering greatly contributed to the increasing popularity of bioanalytical and biophysical applications of surface plasmon resonance (SPR) by providing novel materials, surface chemistry, instrumental concepts, and theory to further understand the plas…
In this work, a facile approach was successfully developed for in situ catalyzing Au nanoparticles loaded on Fe3O4@SiO2 magnetic nanospheres via Sn(2+) linkage and reduction. After the Fe3O4@SiO2 MNPs were first prepared via a sol-gel process, only one step was needed to synthesize the Fe3O4@SiO2-Au magnetic nanocompo…
A pyridinyl-functionalized tetraphenylethene (Py-TPE) was synthesized and it demonstrated colorimetric and ratiometric fluorescent responses to trivalent metal cations (M(3+), M = Cr, Fe, Al) over a variety of mono- and divalent metal cations.
Mg2+ intercalation/deintercalation is achieved by using aqueous electrolytes and Prussian blue analog electrodes. Ex situ X-ray diffraction evidenced the solid solution process of Mg2+ intercalation/deintercalation, while the 57Fe Mössbauer spectroscopy and X-ray absorption near edge structure revealed redox of both C…
Hyaluronic acid (HA)–graphene oxide (GO) conjugates, with a high loading of photosensitizers (PS; Ce6), were developed as a cancer cell targeted and photoactivity switchable nanoplatform for photodynamic therapy (PDT). HA–GO conjugates with size below 100 nm were first prepared by the chemical conjugation between ADH-…
Carbon materials, especially Vulcan XC-72 carbon black, are the most widely used catalyst support in low temperature fuel cells. Several disadvantages of these catalyst supports, however, limit the catalyst performance leading to reduced fuel cell performance and durability: low resistance to corrosion at high potenti…
Nanocrystals of ZIF-90 have been synthesized at room temperature through a novel procedure and incorporated into PBI-based nano-composite membranes for hydrogen purification. The physical and chemical structures of the ZIF-90 nanoparticles have been examined via multiple advanced instrumental analyses including DLS, X…
ZnWO4/BiOI heterostructures with different constituents are synthesized via a chemical bath approach under mild conditions by tuning the Zn/Bi molar ratios. The obtained ZnWO4/BiOI heterostructures display high photocatalytic activities in degradation of MO and photocurrent response under visible light irradiation. Co…
Hybrid photocatalysts consisting of single crystalline BiFeO3 nanowires and laser ablated Au nanoparticles were synthesized by a functionalization-step-free solution process. The 1.0 wt% Au nanoparticle decorated BiFeO3 nanowires exhibit ~30 times higher photocatalytic activity for water oxidation than that exhibited…
Liquid drops start spreading directly after coming into contact with a solid substrate. Although this phenomenon involves a three-phase contact line, the spreading motion can be very fast. We experimentally study the initial spreading dynamics, characterized by the radius of the wetted area, for viscous drops. Using h…
A rhodamine based highly selective colorimetric and fluorescent probe for fluoride has been designed and synthesized. The fluorescent change is attributed to the fluoride triggered spirolactam ring opening which is augmented by density functional theory calculations and 1H NMR titrations. The sensor has been shown to…
A highly luminescent LnMOF {[Eu2(bqdc)3(H2O)(DMF)3]·0.5DMF·H2O}n (1, bqdc = 2,2′-biquinoline-4,4′-dicarboxylate) was designed and synthesized. It was characterized by single crystal X-ray diffraction, PXRD, TGA, EA and FT-IR. A new strategy for preparing mechanically robust MOF thin films was developed by electrodepos…
The adjustment of size-dependent catalytic, electrical and optical properties of gold cluster assemblies is a very significant issue in modern applied nanotechnology. We present a real-time investigation of the growth kinetics of gold nanostructures from small nuclei to a complete gold layer during magnetron sputter d…
A heterostructured Ag3PO4/AgBr/Ag plasmonic photocatalyst was prepared by a rational in situ ion exchange reaction between Ag3PO4 micro-cubes and Br(-) in aqueous solution followed by photoreduction. The photocatalytic activities of obtained photocatalysts were measured by the degradation of methyl orange (MO) and met…
CO hydrogenation, CO2 hydrogenation, and water–gas shift (WGS) reactions have been simultaneously investigated over industry-like catalysts based on Cu–ZnO–Al2O3, under methanol synthesis conditions (513 K, 5.0 MPa). For this, a novel methodology has been applied: the concentration of carbon dioxide in the syngas feed…
Non-cellulosic cell wall polysaccharides constitute approximately one quarter of usable biomass for human exploitation. In contrast to cellulose, these components are usually substituted by O-acetyl groups, which affect their properties and interactions with other polymers, thus affecting their solubility and extracta…
Nitrogen doped porous carbon nanopolyhedra (N-PCNPs) were prepared from direct carbonization of ZIF-8 nanopolyhedra. The N-PCNPs showed uniform morphology, narrow pore-size distribution centered at 3.7 nm, high surface area (2221 m2 g−1) and good electrochemical properties and were used to modify a glassy carbon elect…
The transformation from the fatuous consumption of fossil energy towards a sustainable energy circle is most easily marketable by not changing the underlying energy carrier but generating it from renewable energy. Hydrocarbons can be principally produced from renewable hydrogen and carbon dioxide collected by biomass.…
The cardiovascular system is particularly well-suited to modelling with microfluidic technologies, and much progress has been made to create microfluidic devices that mimic the microvasculature. In contrast, microfluidic platforms that model larger blood vessels and heart valves are lacking, despite the clear potentia…
