Heptamethine cyanine dyes are a class of near infrared fluorescence (NIRF) probes of great interest in bioanalytical and imaging applications due to their modifiability, allowing them to be tailored for particular applications. Generally, modifications at the meso-position of these dyes are achieved through Suzuki-Miyaura C-C coupling and SRN1 nucleophilic substitution of the chlorine atom at t...

The transient dimerization of transmembrane proteins is an important event in several cellular processes and computational methods are being increasingly used to quantify their underlying energetics. Here, we probe the thermodynamics and kinetics of a simple transmembrane dimer to understand membrane protein association. A multi-step framework has been developed in which the dimerization profil...

Iron complexes of the meso-(tetraaryl)porphyrin, 5,10,15,20-tetrakis(2-chloro-6-fluorophenyl)porphine (H2ClFTPP) are reported. This unique ligand affords the opportunity to study atropisomerism in a porphyrin system containing similar substituents in the 2 and 6 positions of the meso-aryl rings. The atropisomerism displayed by the iron porphyrinates is observed to be a function of both the oxid...

Urban areas can represent a considerable part of the model domain in meso-scale numerical simulations with typical horizontal domain lengths of 20–200 km. This paper addresses the question of the extent of the influence of urban surfaces on the development of convective precipitation in meso-g-scale numerical models. For this purpose, a spatially variable parameterization scheme for surface sen...

Nucleophilic ring opening of dl and meso 1,1¢- dicyclohexenyl diepoxides by sodium azide in dioxane and aqueous alcoholic medium give the corresponding azidoalcohols. The obtention of departure diepoxides from diazidoalcohols by the reaction with sodium hydride shows the anti position of OH and N3 groups.

A surface meso-structure measurement and tactile device input vibration signal synthesis techniques are proposed. To measure the surface meso-structure, some photos are taken using a fixed camera with changing lighting incidence direction. A surface normal image is obtained from these photos. Then vibration signal as tactile device input signal is synthesized. Adding friction sound, the tactile...

Photoinduced twisted intramolecular charge transfer (TICT) of meso-(4-dimethylamino)phenylamino subporphyrin and meso-(4-nitro)phenylamino subporphyrin has been revealed by steady-state and time-resolved absorption/fluorescence experiments and quantum calculations. Subporphyrins and undergo molecular twisting at the Cmeso-N bond and the N-Cipso bond, respectively, to trigger intramolecular char...
