Electrospinning is a nano-fabrication technique that easily produces ceramic oxide nanofibres which can find numerous applications as energy storage materials, such as battery electrodes. Vanadium oxide is a viable alternative electrode material with tuneable oxidation states and a layered struc...
A series of vanadium(V) complexes with chiral tridentate Schiff base ligands were prepared. Five-coordinate complexes were obtained by a single condensation of 1S,2R(+)-2-amino-1,2-diphenylethanol with salicylaldehyde and its derivatives. Furthermore, six-coordinate complexes were synthesized wi...
The carrier concentration and effective mass of mesoporous SrTiO3 films were controlled by the substitution of Ti with V-group elements (V, Nb, and Ta) to enhance the thermoelectric properties. We calculated the effect of the substitution on the effective mass of SrTiO3 by analyzing its structur...
Oncolytic viruses (OV) are an emerging class of anticancer bio-therapeutics that induce antitumor immunity through selective replication in tumor cells. However, the efficacy of OVs as single agents remains limited. We introduce a strategy that boosts the therapeutic efficacy of OVs by combining...
A series of vanadium(V) complexes with chiral tridentate Schiff base ligands, obtained by a single condensation of S(+)-isoleucinol with salicylaldehyde and its derivatives, and also six-coordinate complexes with additional monoanionic bidentate benzohydroxamate co-ligand, were prepared. The com...
Nanobelt-arrayed vanadium oxide hierarchical microspheres were synthesized to catalyze selective oxidation of 5-hydroxymethylfurfural to 2,5-diformylfuran with the high conversion and selectivity of 93.7% and 95.4%, respectively. This prominent performance can be attributed to the major exposure...
A series of vanadium(V) complexes with chiral tridentate Schiff base ligands, obtained by a single condensation of 1R,2S(−)-norephedrine with salicylaldehyde and its derivatives, were prepared. The complexes were characterized by elemental analysis and by their IR, CD, UV–Vis, 1D (1H, 51V) and ...
A series of vanadium(V) complexes with chiral tridentate Schiff base ligands, obtained by a single condensation of R(−)-1-amino-2-propanol with salicylaldehyde and its derivatives, were prepared. The complexes were characterized by elemental analysis and by their IR, CD, UV–Vis, 1D (1H, 51V) an...
Vanadium oxide particles are synthesized in an ambient condition using an electron beam irradiation system. The formation of vanadium oxide particles is confirmed by the vibrational modes shown in FT-IR spectra, and the binding energy of V 2p3/2 and V 2p1/2 in the X-ray photoelectron spectrum. I...
Derivatives of 2-(1,4-cyclohexadienyl)glycine were subjected to total ozonolysis. The free esters as well as the N-protected esters tend to cyclize to yield 2-carbethoxy-3-hydroxy pyrrole derivatives. By treatment of the ozonolysis mixture with hydroxylamine or phenylhydrazine heterocyclic deriv...
A practical strategy has been described for the preparation of 6-trifluoroethyl-phenanthridine derivatives using a visible-light-promoted trifluoroethylation reaction of 2-isocyanobiaryl with trifluoroethyl iodide. These reactions could be carried out at room temperature in good to excellent che...
A mild and efficient method for the synthesis of 6-difluoromethylenephosphonyl-phenanthridines through visible-light-promoted radical difluoromethylenephosphonation of 2-isocyanobiaryls with bromodifluoromethylphosphonate has been developed. The reaction allows the direct formation of Csp2CF2PO(...
