In the designed copolymers of poly(9-(4-vinyl benzyl)-9H-carbazole) (PVCz)-random-poly(1-(4-nitro-azo-phenyl)-pyrrole-2, 5-dione) (PMIDO3), carbazole donor and nitro-azobenzene acceptor are introduced into the lateral chains to induce charge transfer under an electric field, and the resulting copolymers have a progres…
Endothelial progenitor cell (EPC)-capturing techniques have led to revolutionary strategies that can improve the performance of cardiovascular implant devices and engineered tissues by enhancing re-endothelialization and angiogenesis. However, these strategies are limited by controversies regarding the phenotypic iden…
The hybrid zero-valent-iron (hZVI) process is a novel chemical treatment process that has shown great potential in previous laboratory and field bench-top scale tests for removing selenium, mercury and nutrients from various industrial wastewaters. In this study, a pilot-scale demonstration was conducted to continuous…
Rh-substituted α-Fe 2 O 3 (Fe 2- x Rh x O 3 ; 0.0≤ x ≤2.0) thin films were grown on α-Al 2 O 3 (110) substrates with a Ta-doped SnO 2 electrode layer by pulsed laser deposition. Highly oriented epitaxial films with pure corundum structures were successfully fabricated over the entire compositional range. The optical a…
Two different nano-sized zinc oxide (ZnO) composite electrodes are prepared and their electrode performances are compared, in which conductive carbon is added as either a physical mixture (electrode A ) or a matrix (electrode B ). The ZnO composite electrode prepared according to the commonly used method (electrode A…
ILs of dications with linked protic and aprotic centres have been prepared. They have rich H-bonding and a Brønsted acid–base character like small ΔpKa protic ILs, but very low apparent vapour pressures, more akin to aprotic ILs.
Novel biomaterials based on hydrophilic polycaprolactone and polyurethane (Tecophilic®) nanofibers with an encapsulated 5,10,5,20-tetraphenylporphyrin photosensitizer were prepared by electrospinning. The doped nanofiber textiles efficiently photo-generate O(2)((1)Δ(g)), which oxidize external chemical and biological…
We present a comprehensive study of structural and electronic properties of the adsorbate system H${}_{2}$-phthalocyanine (H${}_{2}$Pc) on Ag(111). A comparison with copper-phthalocyanine (CuPc) on Ag(111) allows us to elucidate the impact of the central metal atom in the molecule on the adsorbate-substrate interactio…
An optical plasmonic-based sensing array has been developed and tested for the selective and sensitive detection of H(2), CO, and NO(2) at a temperature of 500 °C in an oxygen-containing background. The three-element sensing array used Au nanoparticles embedded in separate thin films of yttria-stabilized zirconia (YSZ…
Switching on uranium(V) reactivity: The silylated uranium(V) dioxo complex [(Me(3)SiOUO)(2)(L)(2)] (A) is inert to oxidation, but after two-electron reduction to [(Me(3)SiOUO)(2)(L)](2-) (1), it can be desilylated to form [OU(μ-O)(2)UO(L)(2)](2-) (2) with reinstated uranyl character. Removal of the silyl group uncover…
Recently, extensive research has been focused on the progressive collapse analysis of the multi-storey buildings. However, most of the research is based on the alternative path method (APM) with sudden removal of the columns, ignoring the duration of the blast load working on the structures. In this paper, a 3-D numer…
Cobalt and chromium substituted lithium-excess manganese oxides, Li[Li 0.2 Co x Cr 0.4- x Mn 0.4 ]O 2 ( x = 0, 0.2, and 0.4), are synthesized by a simple combustion method. Crystal structures of the samples are examined by an X-ray diffraction (XRD) method. The samples crystallize into a rhombohedral layered phase wit…
Recent developments in the synthesis of CuO nanoparticles (NPs) and their application to the [3+2] cycloaddition of azides with terminal alkynes are reviewed. With respect to the importance of click chemistry, CuO hollow NPs, CuO hollow NPs on acetylene black, water-soluble double-hydrophilic block copolymer (DHBC) na…
Two new heterometallic copper(II)-mercury(II) complexes [(CuL)Hg(N3)2]n (1) and [(CuL)2Hg(N3)2] (2) and one copper(II)-cadmium(II) complex [(CuL)2Cd(N3)2] (3) have been synthesized using "metalloligand" [CuL] (where H2L = N,N'-bis(salicylidene)-1,3-propanediamine) and structurally characterized. Complex 1 is a one-dim…
The heme(a3)/Cu(B) active site of cytochrome c oxidase is responsible for cellular nitrite reduction to nitric oxide; the same center can return NO to the nitrite pool via oxidative chemistry. Here, we show that a partially reduced heme/Cu assembly reduces NO(2)(-) ion, producing nitric oxide. The heme serves as the r…
Human adipose-derived stromal/stem cells (ASCs) are an abundant, readily available population of adult stem cells that reside in adipose tissue and that have a great potential utility for tissue engineering and regenerative medicine therapeutic applications. Several preclinical studies have shown that ASCs have therap…
The previously proposed exact two-component (X2C) relativistic theory of nuclear magnetic resonance (NMR) parameters [Q. Sun, W. Liu, Y. Xiao, and L. Cheng, J. Chem. Phys. 131, 081101 (2009)] is reformulated to accommodate two schemes for kinetic balance, five schemes for magnetic balance, and three schemes for decoup…
A 2D phosphonate MOF {[Ni(Hptz)2]·7H2O}n (H2ptz = 4-(1,2,4-triazol-4-yl)phenylphosphonic acid) (2) is obtained through crystal transformation from a trinuclear compound [Ni3(Hptz)6·(H2O)6]·9H2O (1). Studies of chemical stability show that 2 retains its crystallinity in boiling water and organic solvents. 2 also exhibi…
Spin polarization of a topological surface state for GeBi${}_{2}$Te${}_{4}$, the newly discovered three-dimensional topological insulator, has been studied by means of state-of-the-art spin- and angle-resolved photoemission spectroscopy. It has been revealed that the disorder in the crystal has a minor effect on the s…
We studied the effects of various surfactants on the shape and morphology of three metal organic frameworks (MOFs), i.e., Co-MOF, Cu-MOF, and In-MOF, which were synthesized under microwave irradiation. The as-synthesized materials were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM)…
