We report the synthesis and the photochromic behavior of a newly designed, photochromic, radical diffusion-inhibited hexaarylbiimidazole (HABI) derivative with markedly improved photochromic performance in coloration and decoloration rates as well as greater optical density in the colored state. The thermal bleaching rate (tau1/2 = 260 ms at 295 K) is the fastest among the reported ones for HAB...

Awareness of, and debate about, harassment, assault, bullying intimidation (HABI) in archaeology has grown recent years, but the issue remains under-researched. Here, authors present first Europe-wide survey to evaluate HABI archaeological environments, from field laboratory classroom. The covers 18 forms of HABI, collecting more than 1000 responses archaeologists 49 nationalities. A total 82 p...

Under mechanical stress, the hexaarylbiimidazole (HABI) motif can cleave to triphenylimidazolyl radicals when incorporated into a polymer matrix. The mechanically produced coloured radicals can initiate secondary radical reactions yielding polymer networks. Thus, the HABI mechanophore combines optical reporting of bond scission and reinforcement of polymers in a single molecular moiety.

As intelligent materials responsive to light, photomechanical hydrogels not only possess high-water content, excellent softness and biocompatibility, but also can accomplish various mechanical motions upon spatiotemporal stimulation of external which exhibit great potential in biomedical underwater bionic fields. Molecular photoswitches have been used broadly preparation owing their high photos...

It was decided to estimate the plasma glucose leve l in the monkeys soon a f te r being caught in the wild. This would give an idea of the plasma glucose level in their natura l habi ta t ion. Ar rangements were made to trap four monkeys individually in the nearby areas on d i f fe rent days a f te r 12:00 noon. Random plasma glucose was estimated within an hour after being caught and transport...

Abstract Sandhoff disease (SD) is an ultra-rare lysosomal storage disorder (LSD), which affects ~ 1/1000, 000 live birth. SD caused by genetic deficiency of beta (β) Hexosaminidase and resulting excess central nervous system (CNS) synthesis GM2 ganglioside (GM2) its impact on neuron death. The exact mechanisms underlying such GM2-driven death are unknown in SD. Glucosylceramide (GC) induced com...

Chlorine substituted hexaarylbisimidazole (o-Cl-HABI) efficiently initiates radical polymerization of multifunctional acrylic esters in the presence of a heterocyclic mercapto compound if the latter can form its tautomeric thione. Exposure of o-Cl-HABI results in lophyl radicals, which efficiently add to the thione in the first step while the second step releases a highly reactive thiyl radical...

INTRODUCTION: Ocular morbid condi t ions are responsible for part ial or total bl indness. Ocular morbidi t ies by i ts sheer magni tude form an enormous problem, not only in human suf fering, but also in terms of economical loss and social burden . OBJECTIVE: To study some epidemiological determinants of ocular morbidi t ies in rural area. MATERIAL AND METHODS: Present Community Based Cross-Se...
