MnO <sub>2</sub> /porous carbon microspheres with a partially graphitic structure were designed and synthesized for high performance supercapacitor electrode materials.
Gold nanostructures possess unique characteristics that enable their use as contrast agents, as therapeutic entities, and as scaffolds to adhere functional molecules, therapeutic cargo, and targeting ligands. Due to their ease of synthesis, straightforward surface functionalization, and non-toxicity, gold nanostructur…
There has been a rapid expansion in the use of molecular magnets for both low- and ultra low-temperature cooling applications in recent years, and here we review the chemical variation and magnetothermal properties of reported molecular coolers, structuring the review by structural dimensions, metal-ions involved and…
Structural Classification of Proteins-extended (SCOPe, http://scop.berkeley.edu) is a database of protein structural relationships that extends the SCOP database. SCOP is a manually curated ordering of domains from the majority of proteins of known structure in a hierarchy according to structural and evolutionary rela…
Solid oxide fuel cells (SOFCs) have the potential to be one of the cleanest and most efficient energy technologies for direct conversion of chemical fuels to electricity. Economically competitive SOFC systems appear poised for commercialization, but widespread market penetration will require continuous innovation of m…
The geometries and electronic structure properties of pristine and carbon-doped (6,0) boron-phosphide nanotubes (BPNTs) were studied by density functional theory. In order to characterize and provide valuable information of the origin of noncovalent interactions, electrostatic potentials were computed on the surface o…
The basic design schemes of construction of cylindrical transducers with longitudinal and transverse piezoelectric effect, and their features, namely, power and compensated design. The sound field of circular cylindrical piezoceramic emitters with longitudinal and transverse piezoelectric effect was defined by Using t…
New composite material—multi-walled carbon nanotubes (MWCNTs) coated with thin iron films—have been prepared by MOCVD growth technique using iron pentacarbonyl as the iron source. Their structures and morphologies were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy,…
Carbon nano-onions and multi-walled carbon nanotubes (MWCNTs) are synthesized by needle-pulsed arc discharge plasma. In a simple production apparatus, a needle pulsed plasma is applied between two graphite electrodes in the presence of an electric field between anode and cathode. The possibility of carbon nanotube pro…
High-field magneto-optical spectroscopy was performed on highly enriched (6,5) single-walled carbon nanotubes. Spectra of phonon sidebands in both 1st and 2nd sub-bands were unchanged by an external magnetic field up to 52 T. The dark K-momentum singlet (D-K-S) exciton, which plays an important role for the external q…
In this article, we synthesize phosphate-graphite oxide (GO) intercalation compounds using two different methods. The expanded interlayer distances of graphite oxide after synthesis was evidenced by X-ray diffraction, which was favorable for intercalation reaction. The fact that no grains of phosphates was observed by…
In this article, the nanotubes obtained by silicon atoms substitutionally doping the single-walled carbon nanotubes were investigated by quantum chemistry calculations under the framework of density functional theory. The geometrical structures, relative stabilities and electronic properties of the Si-doped tubes were…
This paper reports on substrate-induced bianisotropy in an impedance-matched near-zero-index metallodielectric fishnet nanostructure with vertical sidewalls and a supporting substrate. The effect of bianisotropy on the metamaterial optical properties is confirmed through spectral holography measurements and full-wave…
This paper reports a theoretical analysis of the electronic structure and magnetic properties of a ferromagnetic Cu(II) [2 × 2] grid. The calculations confirm a quintet (S = 2) ground state and an energy-level distribution of the magnetic states in accordance with Heisenberg behaviour. The whole set of first- and seco…
The one-pot chemical functionalization of short carboxyl multi-walled carbon nanotubes (Sh-MWCNT-COOH) with ninhydrin and thiourea for producing 3a,8a-dihydroxy-2-thioxo-1,3,3a,8a-tetrahydroindeno[1,2-d]imidazol-8(2H)-one (Sh-MWCNT-inden) via thermal and microwave methods have been investigated. The product was charac…
The currently increasing awareness of an alarming lack of specific knowledge on developmental nanotoxicity significantly adds to the anyway growing anxiety about possible adverse health effects of ...
Thermoplastic polyurethanes (TPUs) are widely used in biomedical applications because of their excellent mechanical properties and biocompatibility. However, their role as possible matrices for drug delivery has received little attention. In this study, the loading and release of model drugs from different TPUs using…
Abstract Owing to their applications in biodetection and molecular bioimaging, near‐infrared (NIR) fluorescent dyes are being extensively investigated. Most of the existing NIR dyes exhibit poor quantum yield, which hinders their translation to preclinical and clinical settings. Plasmonic nanostructures are known to a…
Strongly enhanced and spatially confined near-fields in the vicinity of plasmonic nanostructures open up exciting new capabilities for photon-driven processes and particularly also for optical spectroscopy. Surface enhanced Raman signatures of single molecules can provide us with important information about the optica…
We investigated the device characteristics of a graphene field effect transistor (FET) of which interfaces were controlled by a self-assembled monolayer (SAM). Electrical transport measurements together with Raman spectroscopy characterizations for bilayer graphene (BLG) and single layer graphene (SLG) on micro-patter…
