Complex oxide nanocrystals with a spinel structure show their remarkable optical, electronic, mechanical, thermal, and magnetic properties. In this study, we present a simple yet versatile strategy to grow selfassembled epitaxial CoFe2O4 nanocrystals with well-controlled size (less than 10 nm) and single orientation. CoFe2O4 nanocrystals were fabricated via phase separation in a BiFeO3–CoF2O4 u...

The in vitro activities of piperacillin (PIP) against beta-lactamase-negative ampicillin (AMP)-resistant (BLNAR) Haemophilus influenzae were compared with those of cefotaxime (CTX) and ceftriaxone (CRO), and the potency of PIP as therapy for meningitis caused by BLNAR is also discussed. PIP showed good activity (MIC at which 90% of strains are inhibited, 0.25 micro g/ml) against 69 BLNAR strain...

Recycling and reusing spent lithium-ion batteries (LIBs) have gained a lot of attention in recent years, both ecologically commercially. The carbon nanotube-loaded CoFe2O4 (CoFe2O4@CNTs) composite was made using solvothermal technique utilizing wasted LIBs as the starting material nanotubes support, it used an efficient peroxymonosulfate (PMS, HSO5−) activator to degrade chloroquine phosphate (...

To develop an artificial photosynthesis model, the anionic water-soluble carotenoid dye crocetin was electrostatically immobilized onto the surface of cationic surfactant cetyltrimethylammonium bromide (CTAB) micellar medium including Mg chlorophyll-a and b (MgChl-a and b) (Cro/MgChl), and its photophysical properties were studied using UV-vis absorption and fluorescence spectroscopy. The fluor...

A novel molecular tool for double-stranded (ds) DNA detection using synthetic peptide is described. The peptide was designed based on the DNA binding domain of the lambda phage CRO repressor (CRO). The designed peptides contain helix-turn-helix (HTH), which is DNA binding motif. A cyclic peptide and a mutant peptide based on CRO were also designed, and the resulting affinity for dsDNA was incre...

in this work, cofe2o4 nanoparticles have been prepared by co-precipitation technique. the synthesized cofe2o4 nanoparticles were applied in the preparation of cofe2o4/polyacrylonitrile fiber nanocomposites by the electrospinning process. the prepared nanoparticles and nanofibers were characterized using the scanning electron microscopy (sem) and x-ray diffraction methods. the results manifested...

Here, we report a spontaneously formed nanolamellar BaTiO3–CoFe2O4 bicrystal. 11̄0 interfaces join the BaTiO3 and CoFe2O4 single crystalline periodically arranged lamellae that have a common 111 direction. The superlattice of approximately 2 nm wavelength is magnetoelectric with a frequency dependent coupling coefficient of 20 mV/Oe cm at 100 Hz. The BaTiO3 component is a ferroelectric relaxor w...
