This technique enables us to prepare transition metal oxide nanostructures down to 200 nm. The hard x-ray photoemission spectroscopy revealed that the resulting nanostructures preserve a fine electric structure as spintronics oxide same as unprocessed films. The resulting FMO nanostructure showed the magnetoresistance of about -0.11% to -0.14% at the magnetic field of 3000 Oe, which value was similar to that of FMO film. These indicate that this technique can construct well defined nanoscale oxides both in structure and physical properties.”

This article enumerates an overview of phytochemical and pharmacological aspects that is useful to researchers for further exploration for the necessary development of this potential herb.”
“A novel quantitative method for the determination of degree of branching in Leuconostoc mesenteroides B-512F dextran was developed by using the combination of 3
dextran-degrading enzymes. First, Paenibacillus sp. endo-dextranase was randomly degraded B-512F dextran into linear or branched isomalto-oligosaccharides with various degree of polymerization
(2-8). Second, Streptococcus mutans dextran glucosidase hydrolyzed linear or branched isomalto-oligosaccharides into glucose and branched isomalto-penta-saccharides. this website Third, the branched isomaltopenta-saccharide was degraded into glucose by using Bacteroides thetaimicron alpha-glucosidase. The number of branching points in B-512F dextran (5.42%) was determined by the difference in the amount of glucose in the reaction digest between BTGase-PDex and DGase-PDex treatments.”
“Unconventional exchange bias (EB) has been studied in CoCr2O4/Cr2O3 nanocomposites, in which the Curie temperature of the ferrimagnetic CoCr2O4 is much lower than the Neel temperature of the antiferromagnetic Cr2O3. A negative EB field of about 2.5 kOe at 5 K is achieved upon cooling in a field of 30 kOe. Meanwhile, the coercivity of the CoCr2O4 nanoparticles has been enhanced significantly by coupling with Cr2O3. The effect of the cooling field on the EB field and coercivity at 10 K has also been investigated. The domain-state model is used to interpret the unconventional EB. Cooling field may play a decisive role in the creation of the interfacial spin configuration for the unconventional EB, not only by exchange interaction between the induced magnetization of a polarized paramagnet and interfacial spins of an antiferromagnet but also by Zeeman interaction between the domain-state surplus magnetization and the external field.
