A hierarchical p-type Cu2O film with nano/microspheres on copper foil is successfully synthesized via a facile and cost-effective liquid reduction route through transformation of a lotus-like CuO/Cu(OH)2 nanosheet/nanowire structure. Various sizes of sphere-like Cu2O are transformed from CuO nanosheets and Cu(OH)2 nan…
A radiation dose above the maximum permissible limit is very dangerous for human being. In radiation shielding, absorbent materials' properties must be well known. Heavyweight concrete is the most widely used in the world for this aim. The aggregate component of concrete plays an important role in improving concrete p…
We demonstrate coherent quantum control of a single spin driven by the motion of a mechanical resonator. The motion of a mechanical resonator is magnetically coupled to the electronic spin of a single nitrogen-vacancy center in diamond. Synchronization of spin-addressing protocols to the motion of the driven oscillato…
Recently there has been fabulous excitement in the nano-biotechnological area for the study of nanoparticles synthesis using some natural biological system, which has led the growth advanced nanomaterials. This intention made us to assess the biologically synthesized silver nanoparticles from the leaf of Suaeda monoic…
The morphology and mechanical properties of chitosan fibers obtained by wet-spinning using chitosan–[Gly]Cl (glycine chloride) ionic liquid as spinning dope solution are reported for the first time. The objectives were to understand both how the microstructure of the fibers could be modified and how the mechanical pro…
Smooth, transparent and nonperfluorinated surfaces exhibiting unusual contact angle (CA) behavior toward various organic liquids have been prepared using a simple sol–gel solution containing decyltriethoxysilane (DTES) and tetramethoxysilane (TMOS). The insertion of co-condensed silica units derived from TMOS as a spa…
Sixteen N,N′-bis(salicylidene)diamines of common formula (o-OHC6H4CN–)2Z [Z = o-C6H4 (1a), m-C6H4 (2a), p-C6H4 (3a), Ø (4a), CH2(p-C6H4)2 (5a), O(p-C6H4)2 (6a), S(p-C6H4)2 (7a), SO2(p-C6H4)2 (8a)] and N,N′-bis(5-bromosalicylidene)diamines of common formula (2-OH-(5-Br)C6H3CN–)2Z [Z = o-C6H4 (1b), m-C6H4 (2b), p-C6H4 (…
Solid-state supercapacitors based on galvanostatic pulse polymerized Poly(3,4-ethylenedioxythiophene) (PEDOT) electrodes and ionic liquid gel polymer electrolyte were fabricated and characterized. For comparative studies, PEDOT electrodes were also deposited by potentiostatic method. The SEM study shows that the pulse…
The effects of uncarbonized (fresh) and carbonized bone particles on the microstructure and properties of polypropylene composites have been studied. The addition of the bone particles ranges from 5 to 25 wt% in uncarbonized and carbonized forms in the polypropylene matrix. The physical and mechanical properties were…
Due to their novel physico-chemical characteristics, semi-conductor nanocrystal quantum dots (QDs) provide an advantageous perspective towards numerous different consumer and medical applications. The most notable potential application of QDs is their use as therapeutic and diagnostic tools in nanomedicine. Despite th…
Molten salts are a kind of inorganic ionic liquid, which have advantages of a wide liquid range, negligible vapor pressure, good solubility characteristics, non-flammability, excellent thermal and chemical stability, and more importantly, they are low-cost and recyclable. These advantages have aroused an appealing gre…
Poly(vinyl alcohol) (PVA) functionalized graphene (f-G) was prepared by ultrasonication of pristine graphene (p-G) in a PVA aqueous solution. PVA macroradicals formed by sonochemical degradation of the PVA solution were successfully trapped by graphene and grafted onto its surface. This was confirmed by transmission e…
Doped strontium titanates have been widely studied as potential anode materials in solid oxide fuel cells (SOFCs). The high n-type conductivity that can be achieved in these materials makes them well suited for use as the electronically conductive component in SOFC anodes. This makes them a potential alternative to ni…
In this study we report the first example of phosphoester bond hydrolysis in 4-nitrophenyl phosphate (NPP) and bis-4-nitrophenyl phosphate (BNPP), two commonly used DNA model substrates, promoted by metal-substituted polyoxometalates (POMs). Different transition metal and lanthanide ions were incorporated into the Wel…
The solid-state structure of ammonia borane is held together by an intricate N-H···H-B proton-hydride bonding network. These intermolecular interactions have long been considered to mediate the release of hydrogen from this material. Here we reveal the silent but important role played by B-H···H-B interactions in the…
New Aurivillius ferroelectrics Na0.5La0.5Bi2Nb2−xWxO9 (NLBN-W, x = 0, 0.01, 0.02, 0.03, and 0.05) by lanthanum (La3+) and tungsten (W6+) co-substitution were prepared by using a solid-state reaction process. The crystal structure of Na0.5La0.5Bi2Nb1.98W0.02O9 (NLBN-W-0.02) was refined by the Rietveld method with powde…
The mechanism of the horseradish peroxidase (HRP)–H2O2-catalysed polymerisation of aniline in the presence of AOT vesicles was investigated. AOT (= bis-(2-ethylhexyl)sulfosuccinate) served as vesicle-forming surfactant and dopant for obtaining at pH = 4.3 and room temperature within 24 h under optimal reaction conditi…
4.7 nm Gold nanoparticles (AuNPs) capped with mesogenic ligands, dispersed in homeotropically aligned smectic A liquid crystal (LC), reversibly form arrays of aggregates with micron-scale periodicities over macroscopic areas at the nematic to smectic A phase transition (TN-SmA). AuNPs with a mixed capping layer of 4′-…
Graphene has been attracting strong attention due to its interesting structure and properties and important applications in many areas. The process of the oxidation of graphite into graphene oxide (GO) and the subsequent reduction of GO into graphene is regarded as an effective process to produce graphene on a large s…
