Alignment behavior of liquid-crystal molecules on the surface of photoreactive polymer films treated by uv-irradiation and rubbing [PDF]
, 2019 Photoreactive polyimides, which contain cinnamoyl and 4-fluorocinnamoyl moieties as side groups, were synthesized, providing a good quality of films. For these polymers in thin Rims, the photoreactivity and photoreaction-induced polymer alignment were ...

X-RAY-SCATTERING STUDIES OF THIN-FILMS OF PHOTOSENSITIVE POLYIMIDES [PDF]
, 2019 Using the techniques of wide-angle X-ray diffraction (WAXD) and small-angle X-ray scattering (SAXS), the morphology of polyimide thin films thermally imidized from several photosensitive polyimide (PSPI) precursors has been investigated and compared with

Non-discrete Euclidean buildings for the Ree and Suzuki groups
American Journal of Mathematics, 2010 We call a non-discrete Euclidean building a {\it Bruhat-Tits space} if its automorphism group contains a subgroup that induces the subgroup generated by all the root groups of a root datum of the building at infinity. This is the class of non-discrete Euclidean buildings introduced and studied by Bruhat and Tits.

Photo- and rubbing-alignable brush polyimides bearing three different chromophores [PDF]
, 2019 Three new photoreactive brush polyimides (PSPIs), each bearing a different type of chromophore (cinnamoyl (CA), 3-(2-furyl)acryloyl (FA), and methacryloyl (MA)) in their bristles (i.e., side groups), are successfully synthesized, and are found to produce

Fully rod-like aromatic polyimides: Structure, properties, and chemical modifications [PDF]
, 2018 Poly(p-phenylene pyromellitimide) and poly(4,4'-biphenylene pyromellitimide) are representatives of fully rod-like polyimides. Their structure and properties in thin films are reviewed.

Synthesis and characterization of a soluble polyimide containing a photoreactive 4-styrylpyridine derivative as the side group [PDF]
, 2019 An aromatic polyimide bearing photoreactive 4-(2-(4-oxyethylenyloxyphenyl)vinyl)pyridine side groups was synthesized and characterized. The polymer is stable up to 300 degreesC and soluble in organic solvents, giving thin films in good quality.

Efficacy and safety of a popular thermogenic drink after 28 days of ingestion
Journal of the International Society of Sports Nutrition, 2008 Background We have recently demonstrated that consuming a thermogenic drink (TD) acutely increases energy expenditure and serum markers of lipolysis in healthy, college-aged individuals.
