A novel intracavity laser diagnostic has been developed to perform quantitative two-dimensional imaging of major species and temperature by using spontaneous Raman scattering and Rayleigh scattering in a turbulent flame. A flash-lamp-pumped dye laser cavity is modified to include sheet-forming optics and 100% reflecting end mirrors. In a comparison of this system with a laser configuration with...

Developments and evaluations from the preceding projects have been presented by Dye, Fagerberg, Midtsveen (2004), Dye & Fagerberg (2004), Dye & Rekkedal (2005), Fagerberg, Rekkedal & Russell (2002), Rekkedal (2002a), Rekkedal (2002b), Rekkedal (2002c), Rekkedal & Dye (2007), Russell (2005). The article by Rekkedal & Dye (2007) builds on the same data, however with specific reference to use of S...

Our objective was to study the properties of the carboxyfluorescein diacetate succinimidyl ester (CFDA-SE) and the methodology of cell labeling using CFDA-SE fluorescent dye. First, we analyzed the kinetics of CFDA-SE fluorescent dye intensity over time. Second, we determined the optimal concentration of CFDA-SE fluorescent dye for cell labeling. Third, we tested the toxicity of CFDA-SE fluores...

Abstract Dye is a major source of water pollution. This mini-review highlights the origin dye, its removal strategies, and recent literature methylene blue Congo red adsorption by activated carbons. Adsorption unique process that relies upon physicochemical properties carbon inherent characteristics dye. Also, factors affecting adsorption, such as contact time, temperature, concentration, were ...

We show here the first example of a hydrogel formed from a symmetrically functionalised diketopyrrolopyrrole aromatic core. Gelation is triggered by change in pH. Not only does this gelator form aggregated, entangled structures at low pH, but it also forms worm-like micelles at high pH. The structures at high pH can be aligned using shear to provide conductive materials.

Prinzmetal et a!, used 24Na for this purpose (1), while others used al bumin 1311 (2). With more extensive experience, procedures improved over the years until, in 1958, Pritchard et al (3) reported an effective method for the external precordial detection and determination of cardiac output with albumin †̃@†̃I. During this time, a good correlation with dye dilution technique by means of arte...

Stimulated emission on three UV transitions in Cd(+) has been observed by transferring population from inner-shell d-electron states, populated by photoionization, to outer-shell p-electron states using the output from a narrow-frequency dye laser. The use of similar techniques in other elements could eventually result in a number of new lasers in the UV and VUV.

Multilayer dye aggregation at the dye/TiO2 interface of dye-sensitized solar cells is probed via first principles calculations, using p-methyl red azo dye as an example. Our calculations suggest that the multilayer dye aggregates at the TiO2 surface can be stabilized by π…π stacking and hydrogen bond interactions. Compared with previous two-dimensional monolayer dye/TiO2 model, the multilayer d...
