A Novel Method for the Improved Skin Whitening Effect Based on Nanostructured Lipid Carrier

The effect of humidity on the holographic grating diffraction efficiency and transmittance kinetics in the E204Q BR gelatin film is investigated. We found a correlation between the accumulation of the red-light absorbing O intermediate in the later part of the E204Q BR photocycle and sharpness (decay to the steady-state) of the holographic recording kinetics. As shown, at humidity exceeding 95% the ratio between the peak and steady-state of the diffraction efficiency for the weak probe beam (670 nm) can reach 8.7 in the E204Q BR film, which is sufficient for realization of an efficient novelty filter.     

Synthesis and mesomorphic properties of resorcyl di[4-(4-alkoxy-2,3-difluorophenyl)ethynyl]benzoate: a novel achiral antiferroelectric banana-shaped mesogen

Two resorcyl di[4-(4-alkoxy-2,3-difluorophenyl)ethynyl]benzoate liquid crystals were prepared and their mesomorphic properties observed and measured. Achiral antiferroelectric phases were seen with increasing length of the hydrocarbon terminal chains.     

Mesogens containing p-polyfluoro-m-nitrobenzoate and 2,3-difluorotolane groups

A series of 4-(4-n-heptoxy-2,3-difluorophenylethynyl)phenyl 3-nitro-4-polyfluoroalkoxybenzoate liquid crystals was synthesized and their phase transition behaviours were studied by optical polarizing microscopy and DSC. The results show that the mesogens containing long polyfluoroalkoxy chain tend to exhibit the smectic A phase.     

Synthesis and mesomorphic properties of fluorinated phenyl 4-[(4-n-alkoxy-2,3-difluorophenyl)ethynyl]benzoates

Three series of fluorinated phenyl 4-[(4-n-alkoxy-2,3-difluorophenyl)ethynyl]benzoate liquid crystals have been synthesized. Their phase transition temperatures were measured by texture observation in a polarizing microscope and confirmed by DSC. Their mesomorphic properties and fluoro-substituent effects were studied in detail.

Synthesis and mesomorphic properties of fluorinated phenyl 4‐[(4‐n‐alkoxy‐2,3‐difluorophenyl)ethynyl]benzoates

Three series of fluorinated phenyl 4‐[(4‐n‐alkoxy‐2,3‐difluorophenyl)ethynyl]benzoate liquid crystals have been synthesized. Their phase transition temperatures were measured by texture observation in a polarizing microscope and confirmed by DSC. Their mesomorphic properties and fluoro‐substituent effects were studied in detail.     

Synthesis and mesomorphic properties of 4-[(4n-alkoxy-2,3-difluorophenyl)ethynyl]phenyl fluoro-substituted benzoates

Three series of novel fluorinated liquid crystals containing a 2,3-difluorotolan unit have been synthesized. Their phase transition temperatures have been measured by texture observation in a polarizing microscope and confirmed by DSC. The influence of the lateral fluoro-substitution is discussed.     

Fluorinated tolan-type nematic mesogens containing a 1,3-dioxan unit

Twenty new 2,5-disubstituted 1,3-dioxans were prepared, and their mesomorphic properties were investigated by optical polarizing microscopy and DSC; all of the compounds exhibit the nematic phase only. With fluorination in the mesogenic core, the melting and clearing points were reduced, but their nematic phase range only slightly shortened.
