We have developed a hierarchical nanoporous layer (HNL) on silicate glass by a simple one-pot etching method. The HNL has a three-dimensionally continuous spongelike structure with a pore size of a few tens of nanometers on its apparent surface. The pore size gradually decreases from the apparent surface to the HNL-bu…
Electrically controlling resonant energy transfer of optical emitters provides a novel mechanism to switch nanoscale light sources on and off individually for optoelectronic applications. Graphene's optical transitions are tunable through electrostatic gating over a broad wavelength spectrum, making it possible to mod…
We report the photocurrent generation in reduced graphene oxide–cadmium zinc sulfide (RGO–Cd 0.75 Zn 0.25 S) nano composite material under simulated solar light irradiation, where the photocurrent increases linearly with increasing incident light intensity. We also report the temperature dependent electrical conductiv…
The concept of generalized ratiometric indicator based surface-enhanced Raman spectroscopy was first introduced and successfully implemented in the detection of Cd(2+) in environmental water samples using Au nanoparticles (AuNPs) modified by trithiocyanuric acid (TMT). Without the use of any internal standard, the pro…
Conducting carbon quantum dots are reported, and single quantum dots were probed using spreading resistance imaging.
Numerous theoretical and experimental efforts have been paid to describe and understand the dislocation and void nucleation processes that are fundamental for dynamic fracture modeling of strained metals. To date an essential physical picture on the self-organized atomic collective motions during dislocation creation,…
Star polyelectrolytes (poly( N, N -dimethylaminoethyl methacrylate) (PDMAEMA)) with dual (temperature and pH) responsive properties were utilized to fabricate multiresponsive microcapsules via layer-by-layer (LbL) assembly. The LbL microcapsules are very robust and uniform, with higher stability and different internal…
Fluorescence lifetime imaging microscopy (FLIM) has been used to image free and encapsulated doxorubicin (Dox) uptake into cells, since interaction of Dox with DNA leads to a characteristic lifetime change. However, none of the reported Dox conjugates were able to enter cell nuclei. In this work, we use FLIM to show n…
Cu bearing stainless steels (Cu SS) possess antibacterial ability due to the release of Cu2+ ions. However, the release mechanism of Cu2+ ions from the steel is still unclear. Therefore, the passive film on the surface of Cu SS, the reason of Cu2+ ions release and chemical reactions during Cu2+ ions release were studi…
The preparation of a new heterobimetallic samarium(II) formamidinate complex and selected reactions of samarium(II) complexes and one samarium(III) formamidinate complex with benzophenone or CS2 are discussed. Treatment of the tris(formamidinato)samarium(III) complex [Sm(DippForm)3] 1 (DippForm = N,N'-bis(2,6-diisopro…
In this work, a high-capacity supercapacitor material based on functionalized three-dimensional (3D) porous graphene was fabricated by low temperature hydrothermal treatment of graphene oxide (GO) using both ionic liquid (IL) and SiO2 spheres as "spacers". In the synthesis, the introduction of dual "spacers" effective…
The magneto-caloric response of the Gd60Co25Al15 amorphous alloys was investigated in this work. The amorphous rod exhibits an excellent magneto-caloric effect with a peak value of magnetic entropy change (−ΔSmpeak) up to 10 Jkg−1K−1 at 125 K under a field of 5 T, and the highest adiabatic temperature change (ΔTad = 5…
Polymer brushes that present side chain functional reactive groups are attractive platforms for the development of functional surface coatings. From the wide spectrum of possible postpolymerization modification reactions, thiol-based conjugation chemistries are particularly appealing as they can be performed reagent-l…
In this paper, a new procedure is presented for life estimation of HVDC cables subjected to the time-varying electrothermal stress associated with load cycles and voltage. The electric-field inversion phenomenon in the insulation of dc cables is accounted for by updating the field profile as the temperature profile ch…
Transparent inorganic materials showing persistent luminescence can act as cover layer and emergency lighting for security signs in the dark. Herein, we report a Mn2+-activated glass and transparent glass ceramics containing spinel-type Zn1+xGa2−2xGexO4 (0 ≤ x ≤ 1) nano-crystals, which show multi-color persistent lumi…
Chirality at the nanoscale, or more precisely, the chirality or chiroptical effects of chiral ligand-capped metal nanoparticles (NPs) is an intriguing and rapidly evolving field in nanomaterial research with promising applications in catalysis, metamaterials, and chiral sensing. The aim of this work was to seek out a…
Nanoparticles have garnered widespread interest for both the imaging and treatment of cancer due to their unique and tunable pharmacokinetics and their ability to carry a high payload of diverse compounds. However, despite these favorable attributes, the extent of tumor accumulation can be severely restricted due to t…
This study spotlights the fundamental insights about the structure and static first hyperpolarizability (β) of a series of 2,4-dinitrophenol derivatives (1-5), which are designed by novel bridging core modifications. The central bridging core modifications show noteworthy effects to modulate the optical and nonlinear…
Novel low dimensional quantum phenomena at (110) LaAlO3/SrTiO3 (LAO/STO) interfaces are expected after the quasi two dimensional electron gas similar to that of (001) LAO/STO interfaces was found at this (110) system. Here, we report the two dimensional superconductivity with a superconducting transition temperature o…
We report on novel composite nanostructures based on boron-doped diamond thin films grown on top of TiO2 nanotubes. The nanostructures made of BDD-modified titania nanotubes showed an increase in activity and performance when used as electrodes in electrochemical environments. The BDD thin films (∼200-500 nm) were dep…
