Abstract Manipulating electronic structure and defects is crucial to achieve on‐demand functionalities of bimetallic sulfide catalysts for oxygen reduction/evolution reactions (ORR/OER). Here, via a vulcanization strategy, defects‐abundant NiCo 2 S 4 needles obtained from sea urchin‐like O are anchored on surface hollow carbon‐sphere (NiCo /HCS). nanoneedles (≈7.5 nm) radially grown shell HCS w...

Tm(3+), Er(3+), Tm(3+)/Er(3+), Tm(3+)/Er(3+)/Eu(3+) single, double and triple activator ion/ions doped nanocrystalline BaGd2O4 (BG) phosphors were prepared by a Pechini type sol-gel process. After annealing at 1300 °C, X-ray diffraction patterns confirmed their orthorhombic structure. Field-emission transmission electron microscope images of the BG sample indicated a nanoneedle-type morphology....

Biomacromolecules have been used as templates to grow hydroxyapatite crystals (HAps) by biomineralization to fabricate mineralized materials for potential application in bone tissue engineering. Silk sericin is a protein with features desirable as a biomaterial, such as increased hydrophilicity and biodegradation. Mineralization of the silk sericin from Antheraea pernyi (A. pernyi) silkworm has...

• Ru-doped hematite nanorods were prepared by precipitation and calcination. Ru-for-Fe substitution (up to 2 mol%) induced a gradual elongation of nanorods. Temperature the Morin transition gradually rose with increased Ru doping. Optical band gap narrowed Cylinder-shaped particles formed in presence 4 or 5 mol% Ru. Nanosized (?-Fe O 3 ) is widely investigated material due its favourable proper...

BACKGROUND The field of structural dynamics of cytoskeletons in living cells is gathering wide interest, since better understanding of cytoskeleton intracellular organization will provide us with not only insights into basic cell biology but may also enable development of new strategies in regenerative medicine and cancer therapy, fields in which cytoskeleton-dependent dynamics play a pivotal r...
