The first benzene-centered, phthalocyanine hexamer has been synthesized by a dicobaltoctacarbonyl-catalyzed trimerization reaction of an ethynyl-bridged bisphthalocyanine and characterized by different spectrometric and spectroscopic techniques.

The main aetiology of cervical cancer is infection with high-risk human papillomavirus (HPV). Cervical cancer is almost 100% curable if detected in the early stages. Thus, information about the presence and levels of HPV in patient samples has high clinical value. As current screening methods, such as the Pap smear test, are highly subjective and in many cases show low sensitivity and specifici...

A cholesterol-appended titanocene gelator was synthesised which forms twisted fibers able to gelate a variety of solvents of different polarity as demonstrated by spectroscopic and microscopic techniques.

Statistical methods for helping characterise and make sense of spectroscopic data are of growing importance in biological research. The quantity of data describing biological objects and systems produced on a daily basis continues to increase, going hand-in-hand with developments in high-throughput techniques, assay multiplexing, minaturisation using nanofluidic devices, and, more commonly, wit...

We present optical interferometric observations of two double-lined spectroscopic binaries, HD 6118 and HD 27483, taken with the Palomar Testbed Interferometer (PTI) in the K band. HD 6118 is one of the most eccentric spectroscopic binaries and HD 27483 a spectroscopic binary in the Hyades open cluster. The data collected with PTI in 2002-2003 allow us to determine astrometric orbits and when c...

Study of interaction between nicotinamide and human serum albumin using spectroscopic techniques molecular docking simulation

In this work, the synthesis and the nonlinear absorption and population dynamics investigation of a series of zinc phthalocyanines (ZnPcs) dissolved in chloroform are reported. In order to determine the relevant spectroscopic parameters, such as absorption cross-sections of singlet and triplet excited states, fluorescence relaxation times, intersystem crossing, radiative decay and internal conv...

The inclusion of carbon nanotubes in polymer matrix has been proposed to enhance the polymer’s physical and electrical properties. In this study, microscopic and spectroscopic techniques are used to investigate the interaction between poly(3-hexylthiophene) (P3HT) and nanotubes and the reciprocal modification of physical properties. The presence of P3HT-covered nanotubes dispersed in the polyme...

There is a number of laser material processing, spectroscopic and interferometric techniques, which have been adapted to the requirements in a variety of demanding conservation applications. Nowadays, a significant number of successful examples of laser cleaning and diagnostic applications of artworks and antiquities rely on the use of different types of lasers. Laser based diagnostic technique...
