We reported one-step engineering of intrinsically fluorescent silver nanoclusters-aptamer assemblies that would allow the development of facile and specific luminescent labels for target tumor cell recognition and analysis.
Nanodiamond exhibits unpaired electrons in magnetization, EPR, NMR and Auger relaxation. Wave functions and eigenenergies of a bound electron in a nanodiamond crystal have been calculated. It has been proved by using quantum mechanical analysis that unpaired electrons are self-condition of a nanodiamond as a limited c…
One of the main goals of DNA nanotechnology is to provide a viable solution to the limitations of top-down approaches in microfabrication schemes. Although a completely practical bottom-up approach is yet to be realized, there has been great progress in integrating the two approaches in the past few years. In this vei…
Ground-state structures of supported C clusters, C(N) (N = 16, ..., 26), on four selected transition metal surfaces [Rh(111), Ru(0001), Ni(111), and Cu(111)] are systematically explored by ab initio calculations. It is found that the core-shell structured C(21), which is a fraction of C(60) possessing three isolated p…
A microwave (MW)-assisted synthesis method for preparation of fluorescent BSA-stabilized and HSA-protected gold nanoclusters (BSA–AuNCs and HSA–AuNCs) has been developed. The reaction time can be shortened from tens of hours to several minutes, thanks to the superheating and non-thermal effects of the MW energy. The o…
The preparation of organic/inorganic layered hybrids has relied on multistep processing. Thus, shortening the synthetic procedure is important for possible future applications, but only a few studies report one-pot syntheses. In this work, we established a simple one-pot solution process to synthesize layered alkyl am…
The transfer of inorganic films from the as-grown substrates to arbitrary surfaces has been demonstrated and investigated as a facile and versatile approach to alter surface properties. The transfer method employed soluble poly(lactic acid) delivery for ease of operation and flexibility in surface adhesion. Superhydro…
Ni2+ doped indium oxide is an important dilute magnetic semiconductor in spintronic device fields. In this paper, Ni2+ doped rhombohedral corundum-type indium oxide nanorods were prepared by simply annealing Ni2+ doped indium hydroxide precursors. The influences of doped concentrations and annealing temperatures on th…
We explore the flux-front patterns during virgin penetration and after remagnetization in the iron-based superconductor Ba(Fe${}_{1\text{\ensuremath{-}}x}$Co${}_{x}$)${}_{2}$As${}_{2}$. After remagnetization, we observe an instability characterized by turbulent dynamics at the vortex-antivortex boundary. Associated wi…
Stress corrosion cracking (SCC) of X80 pipeline steel in a simulated solution of the acidic soil environments in Yingtan China was studied by means of potentiodynamic polarization curves, slow strain rate test (SSRT) and corrosion morphologies characterized by SEM. The results show that X80 pipeline steel has high SCC…
Pb(Zr1-xTix)O3 (PZT) thin films near phase morphotropic phase boundary were deposited on (Pb0.86La0.14)TiO3-coated glass by radio frequency sputtering. A retrieved analysis shows that the lattice parameters of the as-grown PZT thin films were similar to that of monoclinic PZT structure. Moreover, the PZT thin films po…
A surface structure refinement procedure is introduced, which uses both anomalous and non-anomalous crystal truncation rod data simultaneously. It is shown how a single structural model can be refined against data sets measured at different wavelengths and how this can greatly reduce correlations between fit parameter…
An efficient method for X-ray diffraction data collection mapping on a given curved surface has been developed. The method uses a laser–video auto z alignment system to collect a map of heights on a fine mesh grid. It also reconstructs the surface geometry and determines surface normals on a three-dimensional surface…
Keeping in view the possible applications of singlet open-shell molecules as semiconductors, non-classical derivatives of the heterocyclic rings benzobis(thiadiazole) (BBT) and its positional isomer thiadiazolothienopyrazine (TTP) are characterized using DFT methodologies. M06-2X, B3LYP and BHandHLYP functionals were…
Near infrared (NIR) continuous wave laser radiation at the 1,450 nm wavelength was used to weld porcine aorta and skin samples via the absorption of combitional vibrational modes of native water in the tissues. The fluorescence spectra were measured from the key native molecules of welded and non-welded tissues at spe…
Five compounds based on the versatile pyrazole-4-sulfonate anion (4-SO3-pzH = L−) were synthesized by the reaction of ligand HL with ZnO, CdCO3, Ag2O, NaOH and NH3, respectively. Crystals of Zn(4-SO3-pzH)2(H2O)2, Cd(4-SO3-pzH)2(H2O)2, Ag(4-SO3-pzH), Na(4-SO3-pzH)(H2O) and NH4(4-SO3-pzH) were obtained from aqueous solu…
Diesel engines typically require diesel particulate filter (DPF) systems to reduce particulate matter (PM) emissions in order to meet increasingly stringent emission regulations. While there have been noticeable advances in DPF technology, significant efforts are still needed to develop optimum DPF regeneration strate…
Abstract Delta doping of diamond constitutes a very promising route to fabricate novel generation of high power and high frequency electronic devices. However, the achievement of abrupt interfaces between highly boron doped and undoped layers requires the shortest residence times of reactive species in the substrate v…
The structure–property relationships for the n = 2 member (Ba 3 Co 10 O 17 ) of the [BaCoO 3 ] n [BaCo 8 O 11 ] modular family have been studied by comparison to the n = 1 term (Ba 2 Co 9 O 14 ). It orders antiferromagnetically at T N = 62 K with spin ordering in the common [BaCo 8 O 11 ] units similar to that for n =…
An automatic registration of the changing size of a single spherical microbead of a cross-linked polymer was applied for studying the swelling process of the bead by the sorption of vapors and/or liquids. Many representatives of all three basic types of polymeric networks, gel-type, hypercrosslinked, and macroporous,…
