The goal of the present work was to test the feasibility of simple, one-step and solvent-free covalent functionalization of pristine multi-walled carbon nanotubes (MWNTs) and fullerene C60 (as a model system) with amino-substituted crown ethers, namely, 4'-aminobenzo-15-crown-5 and 4'-aminobenzo-1 8-crown-6. The attac…
Abstract Three zinc(II) phosphonocarboxylates, [Zn 3 (m‐bpc) 2 (OH)] ⋅ (CH 3 ) 2 NH 2 ⋅ H 2 O ( 1 ), [Zn 2 (m‐bpc)(m‐Hbpc)(4,4′‐bpy)] ⋅ (CH 3 ) 2 NH 2 ⋅ H 2 O ( 2 ) and [Zn 3 (m‐bpc) 2 (4,4′‐bpy)(CH 3 ) 2 NH] ⋅ H 2 O ( 3 ) (m‐H 3 bpc=3‐phosphonobenzoic acid, 4,4′‐bpy=4,4′‐bipyridine), have been solvothermally synthesi…
Iodine doped TiO2 with different iodine/Ti molar ratios has been firstly synthesized with a low temperature hydrothermal route and has been studied systematically in photocatalysis under visible light condition. The resulting iodine doped TiO2 were characterized by X-ray diffraction (XRD), high resolution transmission…
A prerequisite for the development of photothermal ablation therapy for cancer is to obtain efficient photothermal nanoagents that can be irradiated by near-infrared (NIR) laser. Herein, we have reported the synthesis of WS2 nanowires as photothermal nanoagents by the reaction of WCl6 with CS2 in oleylamine at 280 deg…
Here, a novel poly(lactic-co-glycolic acid) (PLGA)-based nanoparticles (NPs) for magnetic resonance (MR) and fluorescence imaging was developed for cell imaging. PLGA NPs loaded with fluorescent dye Nile red (NR) and surface-coated with poly(ethyleneimine) (PEI) were produced in a single step nanoprecipitation process…
Abstract Various porous materials have shown a great promise as dry sorbents for carbon dioxide (CO2) capture utilizing their large surface areas. Although there have been considerable efforts to find optimal pore size and geometry for a variety of porous materials, systematic experimental study covering various key p…
A three-step synthesis has been developed to fabricate Au nanoparticle-decorated silica spheres as a catalyst (Au/SiO2). The Au/SiO2 catalyst was created by depositing uniformly Au nanoparticles with an average diameter of 5 nm on the SiO2 spheres by using optimal preparation conditions. Furthermore, the ratio of SiO2…
Abstract Room‐temperature self‐assembly was used to fabricate a periodic array of uniformly sized Al3+‐doped SiO2 nanoparticles (Al−SiO2NPs, 20–30 nm). The uniform mesoporous structure was suitable for uniformly incorporating and distributing Pt nanoparticles (PtNPs), which were used as hydrogen‐evolution catalysts in…
Experiments were carried out to study the dripping behavior of vertical burning thermally thin polymethyl-methacrylate (PMMA) with different spacings parallel to the wall. With spacings of 7, 10, 13, 16, 19, 22, and 25 mm, the dripping behavior was studied by infrared video image analysis, and the mass retention was r…
In this study, the influence of device architecture (regular versus inverted) and different interlayers on performance and lifetime of polymer-nanocrystal hybrid solar cells is explored. The absorber layers of the investigated solar cells consist of the low band gap conjugated polymer poly[[9-(1-octylnonyl)-9H-carbazo…
BACKGROUND: Chitosan and Alginate were used as biopolymers to prepare membranes for protein adsorption. The network requires a cross-linker able to form bridges between polymeric chains. Viscopearl-mini(®) (VM) was used as a support to synthesize them. Six different types of membranes were prepared using the main comp…
We investigate the effects of magnesium (Mg) suppressor layer on the electrical performances and stabilities of amorphous indium-zinc-tin-oxide (a- ITZO) thin-film transistors (TFTs). Compared to the ITZO TFT without a Mg suppressor layer, the ITZO:Mg TFT exhibits slightly smaller field-effect mobility and much reduce…
This paper pertains to elastic properties of InAs and GaAs semiconducting crystals containing various amounts of vacancies--the relevant issue in the case of nanostructured electronic materials. The linear relationship between elastic constants and point defects concentration deduced from our classical molecular dynam…
Recently, DNA-nanoparticle conjugates have been widely used as building blocks for assembling complex nanostructures, due to their programmable recognitions, high cellular uptake and enhanced binding capabilities. In this study, a nanoworm structure, which can be applied in fields of drug targeting, image probing and…
The rational design of multitopic organic linkers and access to the single-crystal structures of their metal-organic frameworks violate a long-standing thesis where it is expected to steer the system toward multifunctional MOFs. Here, a porphyrin that is covalently functionalized with pendant tert-butyl groups is used…
In this study, we fabricated Ag-based electrochemical metallization memory devices which is also called conductive-bridge random-access memory (CBRAM) in order to investigate the resistive switching behavior depending on the bottom electrode (BE). RRAM cells of two different layer configurations having Ag/Si₃N₄/TiN an…
A comparative analysis between crude and purified extracts obtained from withered leaves of Terminalia catappa (T. catappa) and pure compounds of anthocyanidins as organic sensitizers in solar cells. The chemical and electronic properties of the extracts and the pure anthocyanidins were examined using spectroscopic st…
Flowerlike SnS2 nanosheets are synthesized by a fast, low-energy, and facile hydrothermal route. Synthetic conditions, such as the sulfur source, reaction temperature, molar ratio of Sn/S in the source material, and reaction time, that vitally affect the morphologies of the final products are investigated. BET measure…
Cellulose fibers were stabilized by treatment with an electron-beam (E-beam). The properties of the stabilized fibers were analyzed by scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and thermogravimetric analysis. The E-beam-stabilized cellulose fibers were car…
