1. (a) When fractions from crude oil are cracked, ethane and ethene can be formed. Draw the structural formulae of ethane and ethene. Show all(g)
Write the chemical formula for the simplest heptane isomer and give its name. Write a structural formula and a condensed structural formula for the alkane ethane. Write a structural formula and a condensed structural formula for the alkane hexane. Write the chemical formula, condensed formula, and...
The grid was blotted for 4 s with a blotting force of level 3 and then vitrified by flash plunging into liquid ethane using Vitrobot Mark IV (Thermo Fisher) set to 4 °C and 100% humidity. Cryo-grids were screened in a Talos F200C (Thermo Fisher) equipped with a CETA camera. ...
The crystal-chemical role of the 1-hydroxyethane-1,1-diphosphonic acid (HEDP) anions in the crystal structures of compounds studied up until now is analyzed. The HEDP anions can function as bi-, tri-, tetra-, penta-, or hexadentate ligands and exhibit fourteen different types of coordination...
The grid was blotted for 3 s with a force level of 2 at 22 °C and humidity of 100%, flash-frozen in liquid ethane and transferred to liquid nitrogen for storage. Micrographs were collected using the SerialEM software suite76 on a 300-kV Titan Krios electron microscope (Thermo Fisher...
Structural isomers are compounds of the same chemical formula that possess different structures and properties based on how...
17). Electronic spectra, magnetic studies, and molecular formula data suggested an octahedral geometry for the metal complexes [50]. The antimicrobial screening data suggested that the metal complexes were more potent than the Schiff base and were highly active against fungal strains compared to ...
Cryo-EM grids were prepared by applying 3 μl of ClC-3 protein sample to a glow-discharged holey carbon grid (Quantifoil Cu R1.2/1.3, 300 mesh) and blotting for 3.5 s under 100% humidity at 4 °C before plunging the grid into liquid ethane using a Mark IV Vitrobot (FEI). ...
In previous study, CAU-10-H, represent by the chemical formula [Al(OH)BDC)]·solvent (BDC = benzene-1,3-dicarboxylic acid), was first reported by Reinsch et al.34. The inorganic building unit (IBU) of CAU-10-H has helical AlO6polyhedra chains that sharecis-corner OH-anions and bide...
Suitable polyhydric alcohols include polyphenols such as resorcinol; catechol; hydroquinone; bis(4-hydroxyphenyl)-2,2-propane, i.e., bisphenol A; bis(4-hydroxyphenyl)-1,1-isobutane; 4,4-dihydroxybenzophenone; bis(4-hydroxyphenol)-1,1-ethane; bis(2-hydroxyphenyl)-methane and 1,5-...
