Identification and analysis of the FAD gene family in
Know More
nbsp 0183 32 Walnut kernels contain a large amount of unsaturated fatty acids such as linoleic acid and linolenic acid which are essential fatty acids for humans and have important effects on growth and health The main function of fatty acid desaturase FAD which is widely distributed in organisms is to remove hydrogen from carbon chains in the biosynthesis of unsaturated fatty acids to generate C=C...
Types of Solids and How to Categorize Them
Know More
nbsp 0183 32 There are six main types of solids each one characterized by specific properties and structures Ionic Solids Ionic solids form when electrostatic attraction causes anions and cations to form a crystal lattice In an ionic crystal each ion is surrounded by ions with an opposite charge...
Structure Performance and Application of BiFeO 3
Know More
nbsp 0183 32 The valence states of Mn ions in BFO are fluctuating among 2 3 and 4 which can make different efforts on the structure and properties of BFO A more stable rhombohedral structure compared to BiFeO 3 is observed when 20 Mn 4 is substituted whereas mixed phases of orthorhombic and monoclinic are observed when more than 40 Fe 3 is substituted 57...
Conductivity electrolytic
Know More
nbsp 0183 32 Conductivity or specific conductance of an electrolyte solution is a measure of its ability to conduct SI unit of conductivity is Siemens per meter S/m Conductivity measurements are used routinely in many industrial and environmental applications as a fast inexpensive and reliable way of measuring the ionic content in a solution...
Lanthanide probes
Know More
nbsp 0183 32 Lanthanide probes are a non-invasive analytical tool commonly used for biological and chemical applications Lanthanides are metal ions which have their 4f energy level filled and generally refer to elements cerium to lutetium in the periodic table The fluorescence of lanthanide salts is weak because the energy absorption of the metallic ion is low hence chelated complexes of lanthanides are...
Effect of Ambient Storage on the Degradation of Ni
Know More
nbsp 0183 32 Layered LiNi Mn Co O 2 NMC811 is one of the high-energy positive electrode cathode materials for next generation Li-ion batteries However compared to the structurally similar LiNi 1/3 Mn 1/3 Co 1/3 O 2 NMC111 it can suffer from a shorter lifetime due to...

nbsp 0183 32 Cu ions can be reversibly driven across a single van der Waals gap by the local electrical field of a scanning probe microscopy tip in ferrielectric CuInP2S6 crystals...
Complexes of Co II Cu II and Ni II with Antineoplastic
Know More
nbsp 0183 32 The aim of this work was to investigate the interaction of Imatinib mesylate with biological ions Cu II Co II and Ni II in ethanol/water solutions Structures of synthesized complexes were characterized by spectroscopy methods Stereo-microscopy was used for...
Heterogeneous anion exchange membranes with nitrate
Know More
nbsp 0183 32 1 Introduction Ion-exchange membranes IEM act as selective barriers that enable the separation of anions from cations With recent advances in IEMs specific membranes can further enable the separation between the mono- and divalent ions 7 8 but there are limitations associated with the selective separation of ions with the same charge and valence nitrate and chloride...
Exploring the structure and dynamics of macromolecular
Know More
nbsp 0183 32 Holo fragment ions produced in UVPD experiments revealed specific regions of AK that exhibited substantial differences in fragmentation throughout the catalytic cycle In particular changes in backbone cleavages involving three α-helices and adenosine binding regions of AK indicated that these elements were in different structural microstates as AK progressed through its enzymatic cycle...
Towards single
Know More
nbsp 0183 32 To understand processes regulating nutrient homeostasis at the single-cell level there is a need for new methods that allow multi-element profiling of biological samples ultimately only available as isolated tissues or cells typically in nanogram-sized samples Apart...
Proteomic analysis of cerebrospinal fluid extracellular
Know More
nbsp 0183 32 Extracellular vesicles EVs are nano-sized particles present in most body fluids including cerebrospinal fluid CSF Little is known about CSF EV proteins in HIV individuals Here we characterize the CSF EV proteome in HIV subjects and its relationship to neuroinflammation stress responses and HIV-associated neurocognitive disorders HAND CSF EVs isolated from 20 HIV...
