There is a revived interest in the discovery and development of new materials and devices for radiation detection for nuclear non-proliferation and medical imaging. Conjugated polymers emerge as a potential candidate for dosimetry and scintillation. This report provides an overview of the fundamental detection physics…
We here demonstrate for the first time the fabrication of jellyfish-like Au-Ag alloys through sequential chemical deposition on a PANI substrate. This methodology can be applied to fabricate not only nanoparticles with complex morphology but also alloys with various compositions.
The simplex optimization for high porous carbons preparation The microporous carbon materials were prepared by chemical activation of Polish coal with potassium hydroxide using the simplex design method for planning the experiments. The experimental parameters were varied to identify the optimum conditions. Coal can b…
This study presents a feasible method for the fabrication of multifunctional magnetic nanoparticles (MNPs) for the targeted coadministration of two anticancer agents, paclitaxel (PTX) and curcumin (CUR). MNPs were first surface modified with N-[3-(trimethoxysilyl)propyl]ethylenediamine to form a self-assembled monolay…
Molten alloys with 50-mol% In-Sb, Sn-Sb, Sb-Bi, and Sb-Pb were examined as anodes for solid oxide fuel cells at 973 K.The cells were operated in the battery mode, without added fuel, in order to understand the oxidation characteristics of these alloys at electrolyte interfaces.Cells using 50-mol% In-Sb and Sn-Sb mixtu…
Novel layered zirconium molybdates (Mo/Zr = 2) in Na+- and NH4+-exchanged forms with a defective crystalline structure and a specific surface area of up to 100 m2 g−1 were synthesized under mild hydrothermal treatment conditions (150 °C, 3 days) without structure-directing reagents. The NH4+- zirconomolybdate material…
3-Ferrocenylazobenzene (3-FcAB)-containing polymers were prepared using solution polymerization and emulsion polymerization. Polymer A, prepared by solution polymerization followed by re-precipitation, and Polymer B, prepared by emulsion polymerization, had spherical shapes with the outer diameters of ca. 300 nm and c…
High aspect ratio graphite nanoplatelets with tunable oxygen functionality are prepared using a two-step scalable process consisting of expansion by thermal plasma processing followed by exfoliation with ultrasonic processing. The result of this process is graphite nanoplatelets in high yield with an average particle…
Pyrene-functionalised gelators self-assemble into nano-fibrillar organogels in DMSO/styrene/divinylbenzene mixtures, which when polymerised yield polymer wafers with two distinct faces, only one of which is fluorescent and has embedded gelator nanofibres.
Denim garments are most preferred of today’s youth. This paper presents the effect of bleach wash using bleaching powder on 100% cotton indigo dyed denim garments (trousers) to develop novel design and cost effective finishing. Garments were processed using three parameters, bleach concentration 5g/l to 15g/l, tempera…
Cellulose acetate (CA) ultrafine hollow fibres containing model core protein (i.e., gelatin) were fabricated by coaxial electrospinning. Proper conditions to fabricate the core-shell fibres were investigated with respect to the solution properties (i.e., viscosity, electrical conductivity, surface tension, and interfa…
Numerous applications require specific properties at polymer surfaces that differ from the bulk. Herein we describe the novel synthesis of a series of multi-end functionalised poly(styrene) and poly(isoprene) additives carrying 1 to 3 fluoroalkyl (CF) groups. The additives were prepared by endcapping the living chain…
Heterometallic compounds of [Ln2Cu3(OH)4(pyba)8(H2O)2]n (1–5) (Hpyba = 4-(4-pyridyl)benzoic acid, Ln = La 1, Pr 2, Sm 3, Eu 4, Gd 5) were hydrothermally synthesized by using lanthanide oxides, Hpyba, and copper halide as raw materials. Structurally, the two-dimensional frameworks of 1–5 possess the very original heter…
The possibility for the switch-over of the growth mode from a continuous network to unidirectional arrays of well-separated, self-organized, vertically oriented graphene nanosheets has been demonstrated using a unique, yet simple plasma-based approach. The process enables highly reproducible, catalyst-free synthesis o…
Tin-doped indium hydroxide (InSnOH) nanowires (NWs) and nanotubes (NTs) were grown from acidic aqueous solutions of inorganic precursors in a simple one-step electrochemically assisted deposition (EAD) process inside Au-plugged anodic aluminium oxide and polycarbonate membranes. When the membranes were used without an…
We present an experimental study on the attractive glass formation in mixtures of colloidal gibbsite platelets and silica spheres. The platelets are 233 nm in diameter, and the diameter ratio between the platelets and the spheres is 13.8. The glass formation is induced by the short-ranged depletion attraction caused b…
The increased activity of alumina-supported palladium catalysts promoted with vanadium oxide has been investigated. Three different vanadium promoted Pd/Al2O3 catalysts with the same composition but synthesized employing sequential and co-impregnation were tested for the total oxidation of propane. The order of impreg…
We report on a novel approach for the design of stimuli-responsive surfaces based on the immobilization of charged ABC triblock terpolymer micelles. The terpolymer consists of a hydrophobic polybutadiene (B) block, a weak anionic poly(methacrylic acid) (MAA) middle block, and a strong cationic end block of quaternized…
Water soluble gold nanoparticles are coated with peptides bearing a dithiol surface active group for studies of lanthanide binding; characteristic red luminescence is observed upon europium binding to the nanoparticles.
La 0.827 Al 11.9 O 19.09 :Eu 2+ ,Mn 2+ (LAO:Eu,Mn) was prepared for ultraviolet light-emitting diodes (UV LEDs) application. LAO has a distorted magnetoplumbite structure which can provide 12-coordinated site for an La ion and two different sites for Al ions, tetrahedral and octahedral sites. Co-activators, Eu and Mn,…
