A unique hierarchical architecture is successfully constructed in a wormhole-like mesopore structure via a multiple nanocasting route. This novel type of hierarchical porous carbon (HPC) consists of three-dimensional ordered macropores (ca. 150 nm) with interconnecting pore windows, and the walls of these macropores a…
Titanium nanomaterials are likely to sink into sediments in substantial quantities due to their wide use in a number of applications for decades. To assess the potential environmental consequences, a better understanding is required of the occurrence and sources of titanium (Ti) nanomaterials in sediments. In this res…
BACKGROUND: Head and neck squamous cell carcinoma (HNSCC) is currently the eighth leading cause of cancer death worldwide. The often severe side effects, functional impairments and unfavorable cosmetic outcome of conventional therapies for HNSCC have prompted the quest for novel treatment strategies, including the eva…
Six lead xanthate adducts Pb(S(2)COR)(2).L [R = Et, (n)Bu, L = bipy, TMEDA (tetramethylethylenediamine), PMDETA (pentamethyldiethylenetriamine)] have been synthesised and the structures of all, save Pb(S(2)COBu(n))(2).TMEDA (4) which is an oil, determined. Pb(S(2)COEt)(2).TMEDA (3) is seven-coordinate at lead through…
Reactive oxygen species have been implicated in various diseases, but attempts to find efficient antioxidant treatments for such conditions have met with only limited success. Here, we have developed an antioxidant nanoreactor by encapsulating a dual-enzyme mimic of superoxide dismutase and catalase, in polymeric nano…
Helical silver nanorod arrays with different arm numbers are designed by oblique angle deposition and their surface-enhanced Raman scattering properties are characterized. Assuming that the hot spots are located at the bends between the arms, and considering the optical absorbance of different layers, the SERS behavio…

Four new nickel(II) complexes, [Ni(2)L(2)(NO(2))(2)]·CH(2)Cl(2)·C(2)H(5)OH, 2H(2)O (1), [Ni(2)L(2)(DMF)(2)(μ-NO(2))]ClO(4)·DMF (2a), [Ni(2)L(2)(DMF)(2)(μ-NO(2))]ClO(4) (2b) and [Ni(3)L'(2)(μ(3)-NO(2))(2)(CH(2)Cl(2))](n)·1.5H(2)O (3) where HL = 2-[(3-amino-propylimino)-methyl]-phenol, H(2)L(') = 2-({3-[(2-hydroxy-benzy…
We demonstrate a novel noncovalent method for producing Gd(III)-functionalized gold nanorods as multimodal contrast agents for MRI and CT imaging. The ligand is connected to the surface of the gold nanorods by a noncovalent bond making the Gd(III) ions directly accessible to water molecules, and resulting in a longitu…
We developed a simple, non-enzymatic approach for the colorimetric detection of glucose based on a gold nanoparticles (Au NPs) assisted silver mirror reaction (AuSMR). The linear range of the concentration of glucose is from 0.04 mM to 1 mM, and the lowest concentration that can be distinguished by the naked eye is 10…
We report the synthesis, structure and magnetic properties of the first molecular cluster and single-molecule magnet to incorporate [Ru(III)(CN)(6)](3-). Frequency-domain Fourier-transform THz-EPR (FDFT THz-EPR) and magnetic susceptibility measurements indicate strongly anisotropic Mn-Ru exchange interactions.
The coexistence of metallic (m-) and semiconducting (s-) single-walled carbon nanotubes (SWNTs) in grown samples remains an obstacle in the application of SWNTs in nano-electronics. We report herein a rational approach to prepare well-aligned s-SWNTs using water vapor as a weak oxidant to etch the m-SWNTs during or af…
We introduce an easy and scalable approach to synthesize α-MoO3-decorated graphene sheets from a graphite electrode by molybdate-assisted electrochemical exfoliation. The samples were examined by transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Fourier transformation infrared spectroscop…
A facile one step route has been developed for the synthesis of highly fluorescent matrix embedded carbon quantum dots (MCQDs) by the assistance of microwave irradiation. The material shows a homogeneous distribution of carbon quantum dots throughout the surfaces of the carbon matrices with an average size of 1 to 3 n…
The high-temperature thermolysis of fatty acid–iron complexes generates magnetic nanoparticles (MNPs) of a precisely controlled size coated with fatty acids and dispersed in oil. Because they are water-immiscible, MNPs are unsuitable for water-based biomedical applications. Ligand exchange reactions that transform oil…
We propose titanium-decorated graphene oxide (Ti-GO) as an ideal sorbent for carbon monoxide (CO) capture and separation from gas mixtures. Based on first-principles calculations, Ti-GO exhibits a large binding energy of ~70 kJ mol(-1) for CO molecules, while the binding energies for other gases, such as N(2), CO(2),…
BCNO phosphor nanofibers, composed of polycrystalline-BCN and B2O3 crystal, were prepared by electrospinning followed by calcination at 700 °C. These showed intense green and yellow emissions under UV-light irradiation that could be seen by the naked eye. The prepared nanofibers were uniform, non-agglomerate, thermall…
This paper explores the correlation of electro-optical properties with dielectric properties of an organic single crystal. The optical constants of the organic aminopyridine single crystal have been studied. The second harmonic generation efficiency of the grown crystal, based on powder measurement, is 2.9 times highe…
Scientists are conducting active research in different fields of engineering, science and technology by adopting the Green Chemistry Principles and methodologies to devise new processes, with a view to help protect and ultimately save the environment from further anthropogenic interruptions and damage. With this in mi…
Electrodeposition for solar cells is an active area of research and it has been shown to provide improved benefits in several solar technologies. For the silicon solar cell contacts, electrodeposited metal contacts result in 1-2% solar cell efficiency improvement due to a lower processing temperature with better yield…
