SnO2 is an n-type semiconductor with rutile crystalline structure and display many interesting optical properties. However, there are limited reports on effect of Mn doped SnO2 on optical properties, prepared by mechanochemical processing. This paper reports the effect of Mn doping on structural and optical properties…
Heterojunction silicon wafer solar cells using an intrinsic amorphous silicon (a-Si:H) thin-film passivation layer between the crystalline c-Si substrate and the thin-film emitter layer have proven to be a viable device structure for high efficiency. While microcrystalline μc-Si:H is a good candidate for the emitter l…
High-energy metal oxide surfaces are considered to be promising for applications involving surface-adsorbate electron transfer, such as photocatalysis and dye-sensitised solar cells. Here, we compare the efficiency of electron injection into different TiO(2) anatase surfaces. We model the adsorption of a carboxylic ac…
An energy-saving and environmentally friendly approach to synthesize zeolite Y from natural aluminosilicate minerals without the involvement of aluminum- and silicon-containing inorganic chemicals was developed. When used as a fluid catalytic cracking catalyst, the resulting zeolite Y exhibited an outstanding catalyti…
Thermosetting terpolymer composed of benzoxazine (BA-a), cyanate ester (BADCy) and epoxy resin (E44) was prepared via co-curing reactions. The curing procedure for the ternary blend was studied by differential scanning calorimetry (DSC) and Fourier transform-infrared spectroscopy (FT-IR), and the thermal, mechanical a…
Association between proton and electron transfer is omnipresent in biological reactions (Photosystem II and a myriad of other systems) and in synthetic reactions (think of the huge number of available Pourbaix diagrams). The renewed interest for these proton-coupled electron transfers (PCET) is due to the possibility…
Deposition of nanocrystalline Sb(2)S(3) onto a mesoporous TiO(2) photoanode is an important process in the fabrication of Sb(2)S(3)-sensitized solar cells. In order to generate oxide-free nanosized Sb(2)S(3), a single-source precursor for the chemical bath deposition of Sb(2)S(3) in nonaqueous media, Sb(III)(thioaceta…
A family of new luminescent lanthanide MOFs have been synthesized and display a strong second-harmonic generation response, which is 6.0 times that of KDP and phase matchable. The LnMOFs also exhibit typical luminescence emissions with high quantum yields (up to 70.0% for Tb).
A novel method has been developed to prepare hydrogenated graphene (HG) via a direct synchronized reduction and hydrogenation of graphene oxide (GO) in an aqueous suspension under (60)Co gamma ray irradiation at room temperature. GO can be reduced by the aqueous electrons (e(aq)(-)) while the hydrogenation takes place…
Leather industry produces huge quantities of bio-waste that can be used as raw material for the bulk synthesis of carbonaceous materials. Here we report the synthesis of multifunctional carbon nanostructures from pristine collagen wastes by a simple high temperature treatment. Our studies reveal that the nanocarbons d…
An ultrafine grained (UFG) ferrite/cementite steel was subjected to intercritical annealing in order to obtain an UFG ferrite/martensite dual-phase (DP) steel. The intercritical annealing parameters, namely, holding temperature and time, heating rate, and cooling rate were varied independently by applying dilatometer…
Light–emitting Electrochemical Cells (LECs) constitute one of the most recent generations of Organic Light–Emitting Diodes (OLEDs). The main difference between LECs and OLEDs is that LECs include mobile ions in the active layer. Ionic transition–metal complexes and especially ionic iridium (III) complexes have recentl…
The ultrasound-assisted cross-linking of chitosan with hexamethylene diisocyanate with the simultaneous incorporation of Pd(OAc)2 resulted in a catalyst which is suitable for the solid-state Suzuki cross-coupling of poorly reactive (hetero)aryl chlorides with phenylboronic acid. Reactions were carried out solvent-free…
Two new calcium and strontium metal–organic frameworks [Ca(SBA)] (CYCU-1) and [Sr(SBA)] (CYCU-2) were prepared by microwave-assisted reactions. Both rigid frameworks are thermally stable up to about 450 °C. As verified by N2, CO2, and H2sorption measurements, the thermally activated CYCU-1 and CYCU-2 exhibit significa…
We report a facile method to prepare nanoarchitectured metal oxides/graphene hybrids as both positive and negative electrodes for Li-ion batteries. The metal oxides/graphene hybrids were synthesized by deposition of metal oxides and exfoliation of graphene sheets in a one-step electrochemical process. The hybrid elect…
Photodynamic therapy (PDT) is an emerging theranostic modality for various cancer as well as non-cancer diseases. Its efficiency is mainly based on a selective accumulation of PDT and imaging agents in tumor tissue. The vascular effect is widely accepted to play a major role in tumor eradication by PDT. To promote thi…
A new fluorene-based bisphenol monomer containing two pendant phenyl groups, 9,9-bis(3-phenyl-4-hydroxy)phenyl-fluorene, was readily synthesized in high yield by a one-step reaction from inexpensive starting materials. A series of poly(ether sulfone)s with clustered sulfonic acid groups was prepared for fuel cell appl…
In this study, bio-based phase change material (bio-PCM) was successfully encapsulated in ultrafine fibers via coaxial electrospinning technique. Natural soy wax was used as the bio-PCM for thermal storage and Polyurethane (PU) was used as the shell material for encapsulation. The bio-PCM fibers were characterized by…
The structures and properties of the homoleptic copper(I) complexes [Cu(1)(2)][PF(6)] and [Cu(2)(2)][PF(6)] (1 = 6,6'-dimethyl-2,2'-bipyridine, 2 = 6,6'-bis{2-[4-(N,N'-diphenylamino)phenyl]ethenyl}-2,2'-bipyridine) are compared, and a strategy of ligand exchange in solution has been used to prepare eight TiO(2) surfac…
A sensitive and selective colorimetric assay method for the detection of Cr3+ has been developed using tripolyphosphate functionalized gold nanoparticles (P3O105−–AuNPs). Infrared (IR) spectra and energy dispersive X-ray spectroscopy (EDS) confirmed that tripolyphosphates capped on the surfaces of gold nanoparticles (…
