Synthesis of selectively fluorinated cyclohexanes : the observation of phenonium rearrangements during deoxyfluorination reactions on cyclohexane rings with a vicinal phenyl substituent [PDF]

, 2015
A study focused on the synthesis of a derivative of all-cis phenyl-2,3,5,6-tetrafluorocyclohexane, incorporating a methyl group at the benzylic position, found that the fluorination reactions of diepoxide and diol precursors, were susceptible to ...

The Radiolysis of Cyclohexane. IV. The Effect of Solutes on the Radiolysis of Liquid Cyclohexane

Nippon kagaku zassi, 1963
The effect of the addition of vanlous solutes, such as iodine, aromatic and olefinic compounds, and acetylene, on the gamma radiolysis of liquid cyclohexane was investigated by measuring the yield of hydrogen and in some cases those of hydrogenated compounds of the solutes.

Phase Equilibria in the Systems Acetone–Methanol, Acetone–Cyclohexane, Methanol–Cyclohexane, and Acetone–Methanol–Cyclohexane [PDF]

Canadian Journal of Chemistry, 1972
The vapor pressure and vapor composition of the methanol–cyclohexane system were investigated at temperatures ranging from 25 to 50°. The same properties of the binary systems: acetone–methanol and acetone–cyclohexane, as well as those of the ternary system: methanol–cyclohexane–acetone, were determined experimentally at 25°.

Micromechanical Insights into Sinter‐Based Additively Manufactured NiTi with Nb as a Sintering Aid

Advanced Engineering Materials, EarlyView.
This study investigates the microstructural and micromechanical behavior of NiTiNb made through filament‐based materials extrusion via chemically correlated nanoindentation. B19' remnants from the original powder lead to Nb gradients within NiTiNb grains due to the short sintering times required in liquid‐phase sintering.

Bioorthogonal Engineering of Cellular Microenvironments Using Isonitrile Ligations

Advanced Functional Materials, EarlyView.
Highly selective chemistries are required for fabrication and post‐cross–linking modification of cell‐encapsulating hydrogels used in tissue engineering applications. Isonitrile ligation reactions represent a promising class of bioorthogonal chemistries for engineering hydrogel‐based cellular microenvironments. Isonitrile‐based hydrogels are stable and
