This study presents a novel nanocomposite conducting plate (CP) reinforced by graphene at a low weight fraction percentage, and compares the properties of this novel nanocomposite CP with those containing various weight fractions of multi-wall carbon nanotubes (MWCNT) (0.2, 0.5, and 1 phr). Adding only 0.2 phr of grap…
Abstract Plasmonics has conventionally been in the realm of metal‐optics. However, conventional metals as plasmonic elements in the near‐infrared (NIR) and visible spectral ranges suffer from problems such as large losses and incompatibility with semiconductor technology. Replacing metals with semiconductors can allev…
A squirting capsule is designed to deliver nanoparticles inspired by the squirting cucumber ejecting its seeds. The capsule has a thermo-sensitive hydrogel shell, and encapsulates nanoparticles by emulsifying the nanoparticle aqueous suspension in the water-in-oil emulsion core. The squirting capsule can completely sq…
The development of hydrogen storage materials with high performance has been attracting considerable attention in recent years. Magnesium hydride, alanates, borohydrides and ammonia borane are the most promising candidates due to their high hydrogen capacity, but each type has its own shortcomings. In this short featu…
Wettability has been recognized as one of the most important properties of fibrous materials for both fundamental and practical applications. In this study, the plasma induced grafting of acrylic acid (AAc) was applied to improve the wettability of the electrospun poly(vinylidene fluoride) (PVDF) nanofiber membranes.…
Graphene has received great attention because of its exceptional properties and formidable potential in various applications. A practical approach to the production of processable graphene sheets in large quantities at low cost is the key to exploiting most proposed applications. Here we show a dehydration and stabili…
In this work, we have successfully developed a mild solution-based route to elaborate well-aligned MoO3 and MoO2 nanorods as the electrode active materials directly on metallic current collectors for the first time. Prior to nanostructure growth, an incubation layer, containing peroxomolybdate precursors is deposited…
BACKGROUND: Accumulating evidence indicate that the degree of dispersion of nanoparticles has a strong influence on their biological activities. The aims of this study were to develop a simple and rapid method of nanoparticle dispersion using a natural lung surfactant and to evaluate the effect of dispersion status of…
Electrostatic spinning (Electrospinning, ES) was applied to prepare Donepezil HCl loaded nanofibers as a potential orally dissolving dosage form. Electrospinning of water solutions of different polymers were performed in order to fabricate a consistent and removable web on the collector with ultra-fast dissolution in…
Colloidal semiconductor quantum rods have demonstrated many advantageous properties as light emitters such as high quantum yield, tunable emission wavelength, and polarized emission. This makes them an interesting optical gain material for laser applications. We report room-temperature gain lifetimes in core/shell CdS…
DFT calculations reveal that aminotriazines have a strong affinity for graphite and suggest that part of the driving force for adsorption is a specific attractive interaction of NR(2) groups with the underlying surface.
In this report, we present a synthetic method for the formation of cuprous sulfide (Cu2S) and lead sulfide (PbS) nanomaterials directly on substrates from the thermolysis of single-source precursors. We find that the final morphology and arrangement of the nanomaterials may be controlled through the concentration of t…
A novel (3,4)-connected 3D self-penetrating metal-organic framework with a nanometre-scale cavity constructed from metallacalix[4]arene building blocks and Keggin-type polyanions has been obtained by using a 1,3-bis(1-methyl-5-mercapto-1,2,3,4-tetrazole)propane ligand.
For the first time, we provide evidence for both heterogeneous nucleation at the mesoscopic scale and the progression of the non-classical crystallization process during the microwave synthesis of cupric oxide (CuO) with sea urchin-like morphology. This work sheds light on the general mechanism of the growth of CuO ar…
Predicting the ability of low molecular weight molecules to form hydrogels is difficult. Here, we have examined the self-assembly behavior of two chemically and structurally similar functionalized dipeptides, one of which is found to form a meta-stable hydrogel (1) and the other forming a crystalline solid (2). To inv…
We report the synthesis of composite RuO(2)/poly(3,4-ethylenedioxythiophene) (PEDOT) nanotubes with high specific capacitance and fast charging/discharging capability as well as their potential application as electrode materials for a high-energy and high-power supercapacitor. RuO(2)/PEDOT nanotubes were synthesized i…
The unique properties of graphene and carbon nanotubes made them the most promising nanomaterials attracting enormous attention, due to the prospects for applications in various nanodevices, from nanoelectronics to sensors and energy conversion devices. Here we report on a novel deterministic, single-step approach to…
In this study, we report a simple method to coat mesoporous silica onto carbon nanotubes (CNTs) via a two-step procedure. Mesoporous CNTs@SiO2 composites have been obtained by extracting cetyltrimethylammonium bromide (CTAB) via an ion-exchange procedure after silica-coated carbon nanotubes were synthesized with the a…
Recently, ionic liquids have been studied as promising solvents for cellulose. Since ionic liquids can be combined freely from different cations and anions, possible candidates are numerous. Therefore, a time efficient method to screen ionic liquids with respect to their solvent power is mandatory to find an optimal c…
The main methods applied to clean plant material for radiocarbon dating are not compound-specific and generally remove only the easily exchangeable components by an acid-base-acid sequence and additional optional steps like Soxhlet extraction to remove resins and oxidative bleaching with NaClO 2 . The products are nor…
