Crystal field theory assumes that all bonding between ligand and metal ion in a complex is electrostatic (ionic). That means there is no exchange of electrons between the metal ion and ligand. Instead, the negatively charged (or polar in case of neutral ligands like $NH_3$) ligand is...
The stability of the complexes depends on various factors which include nature of central metal, nature of ligands, chelating effect, steric effect, resonance effect, etc.Answer and Explanation: We are given the following complexes: ∗[Co(NH3)6]3+∗[Co(NH3)6]2+ I...
with Z as a site on the surface of the catalyst and AZ, CZ and DZ as adsorbed species we arrive at a conclusion that according to Horiuti's rule the basic set of pathways in scheme (4.54) should contain two pathways. Two sets of pathways are shown in the scheme: N(1), N(2) and...
Fine-mapping of HLA genes revealed a strong association between the HLA-DQA1*05 allele with serine at position 75 of HLA-DQ1 (Ser75) and development of DPP-4i-induced non-inflammatory bullous pemphigoid (BP) (79.3% [23 of 29] affected cases versus 16.1% [145 of 901] controls; dominant...
While patients with idiopathic Parkinson's disease (iPD) often perceive tremors as severely disabling, these tremors are, unfortunately, among the most difficult to treat. No in-depth assessment of non-lesion-based therapies for tremor control in idiopathic Parkinson's disease currently exists to ...
To avoid relapses after allogeneic hematopoietic cell transplantation (allo-HCT), graft-versus-leukemia (GvL) effects are absolutely essential. In spite of its advantages, the adoption of allo-HCT is restricted by the emergence of graft-versus-host disease (GvHD). The combined actions of CD4+ ...

Scanning electron micrographs from field emission SEM of human PBT cells before (A) and after (B) 1 minute of stimulation in suspension with 100 ng/mL SDF-1α. Cells were stimulated, fixed, and processed for SEM as described in “Materials and methods.” The arrow indicates the ruffled lea...
The historical option data set covers all symbols that are exchange traded options in the U.S.Equities markets. Note that we do not delete delisted symbols from our history. So symbols like MER, AWE, LU, YHOO, LEH, EMC, AOL, TYC, BBRY, RIMM, KFT, MOT, ABX, BSC, CCIV, CCU, CFC,...
The chemistry field studies all kinds of chemical reactions that happen in the surroundings. Depending upon the reaction path, reactants, conditions, each reaction is divided into certain categories and provided a specific name. When a molecule forms ions, the...
