A smectic C liquid crystal texture consisting of well oriented distinct local single crystals was grown using predefined orientation of single wall carbon nanotubes (SWCNTs) adsorbed on a SiO x layer deposited on a ITO treated glass surface. The orie

We describe the specific features of electroconvection (EC) in the nematic liquid crystal (NLC) phase with short-range smectic C order (the seventh homologue of the p,n-alkyloxybenzoic acid, 7OBA, which is dimeric). These features are revealed below

Electroconvection (EC) in nematic liquid crystals, which appears before smectic C phase at cooling, was studied. Three detached nematic regions with characteristic ECs were detected under temperature variation. The influence of the change of magnitud

Electroconvective (EC) dendrites (parabolic type) in nematic (N) liquid crystals with short range smectic order shown by 4,n-octyloxybenzoic acid (8-OBA) were observed. The driving of the dendrites by lateral d.c. and a.c. electric field parameters i

The photosensitized degradation of deoxyribose and DNA, using hematoporphyrin (HP) and picosecond laser pulses at high intensities (pulse duration 30 ps, λexc = 355 nm, light intensity range 108–1010W/cm2) was studied. Aldehyde formation from 2-de

We investigated a series of nanocomposites, built of the hydrogen-bonded liquid crystal (LC) p-n-heptyloxybenzoic acid (7OBA) and single-walled carbon nanotubes (SWCNTs) by optical microtexture analysis and other complementary methods. The surface or

Hematoporphyrin (Hp) solutions were subjected to a wide range high intensity (0.2–10.0 GW/cm2) near-UV laser pulse radiation (λexc=355 nm, pulse duration 30 ps). The formation of stable Hp photoproducts was followed by UV-VIS absorption spectrosco

The liquid crystalline (LC) nature of alkyloxybenzoic acids is preserved after adding of any mesogenic or non-mesogenic compound through hydrogen bonding. However, this noncovalent interaction provokes a sizable effect on the physical properties as,
