We demonstrate here the utilization of ultrasonication during template-assisted electrodeposition to synthesize high quality one-dimensional nanostructures. Copper sulfide nanorods were synthesized “sonoelectrochemically” to achieve single-crystal nanorods with predominantly single stoichiometric composition (1.0:1.0 Cu:S). Structural characterization by HRTEM, SAD, EDS reveals that nanorods ha...

Photoconductivities in molybdenum disulfide (MoS2) layered nanostructures with two-hexagonal crystalline structure prepared by mechanical exfoliation were investigated. The photoconductor-type MoS2 nanoflakes exhibit remarkable photoresponse under the above bandgap excitation wavelength of 532 nm at different optical intensity. The photocurrent responsivity and photoconductive gain of nanoflake...

Highly crystalline b-Ga2O3 nanowires with two morphologies have been synthesized through physical evaporation of Te doped GaAs powder in Ar atmosphere. Growth is not based on VLS mechanism due to absence of Te. S in place of Te resulted in similar nanostructures. Some of the nanowires exhibit herringbone morphology with presence of hexagonal crystallites in regular spacing along the nanowire ax...

Colloidal route is one of the favored ways toward cost-effective large scale production of various nanostructures [1]. In our study, different types of nanoparticles have been designed and synthesized via colloidal approach, which can be applied for energy storage and other energy-type applications. For example, dispersible mesoporous nitrogen-doped hollow carbon nanoplates have been made by us...

Regular hexagonal embedded ZnO nanorods were successfully prepared by a simple hydrothermal method. The addition of urea as a homogeneous precursor was found to play a vital role in the embedding of secondary nanorods. The nanostructures were characterized by XRD, SEM, and EDS. The gas-sensing properties of secondary grown embedded nanorods were reported for formaldehyde, ethanol, methanol, ace...

It is shown that, by utilizing spin-selective quantum interference, the spin polarization of nanostructures deposited on a magnetic substrate with a surface state can be strongly modulated locally and energetically by an appropriate structural design. This finding is deduced from state-of-the-art ab initio calculations and interpreted within an analytical model. We present results for hexagonal...

High-temperature exposure of a Mo(110) surface to borazine (HBNH)3 leads to the formation of two distinctly different self-assembling nanostructures. Depending on the substrate temperature during preparation, either well-aligned, ultra-thin boron nanowires or a single-layer stripe structure of hexagonal boron nitride forms. Both structures show one-dimensional (1D) characteristics, but in direc...

Highly aligned stringlike silica nanostructures are obtained through templated synthesis in the columnar hexagonal structure of a rigid crystalline surfactant mesophase. A two-step procedure is used to first shear-align the surfactant mesophase and then conduct synthesis under quiescent conditions in the mesophase. The mesophase retains its alignment for extended periods, allowing materials syn...

Highly uniform and dense, hexagonal noble metal nanoparticle arrays were achieved on large-area transparent glass substrates via scalable, parallel processing of block copolymer lithography. Exploring their localized surface plasmon resonance (LSPR) characteristics revealed that the Ag nanoparticle array displayed a UV-vis absorbance spectrum sufficiently narrow and intense for biosensing appli...

This paper describes an effective method for a precursor salt assisted fabrication and reshaping of two different polyoxometalates [(NH4)2Cu(MoO4)2 (ACM) and Cu3(MoO4)2(OH)2 (CMOH)] into five distinctive shapes through straightforward and indirect routes. Explicit regulation of the structural arrangements of ACM and CMOH has been studied in detail with altered precursor salt concentration emplo...
