Abstract Diradicals based on the Blatter units and connected by acetylene alkene spacers have been prepared. All molecules show sizably large diradical character low energy singlet‐triplet gaps. Their photo‐physical properties concerning their lowest excited state studied in detail steady‐state time‐resolved absorption spectroscopy. We fully identified main optical band full absence of emission...

A simple, crude Jatropha curcas (JC) oil-based synthesis approach, devoid of any toxic phosphine and pyrophoric ligands, to produce size and shape tuned CdSe QDs and a further copper sulfide (Cu2S) encasing is presented. The QDs exhibited excellent photoluminescent properties with narrow band gap emission. Furthermore, the Cu2S shell rendered additional cytocompatibility and stability to the hy...

The aim of this study was to enhance the effectiveness of photo thermal therapy (PTT) in the targeting of superficial bladder cancers using a green light laser in conjunction with gold nanoparticles (GNPs) conjugated to antibody fragments (anti-EGFR). GNPs conjugated with anti-EGFR-antibody fragments were used as probes in the targeting of tumor cells and then exposed to a green laser (532nm), ...

This paper will describe the process of designing a desktop photo printing system: printer, ink and media. We will compare recent technology trends in photo printers with respect to customer expectations for imaging system performance. We examine the three fundamental component processes of image printing: preparing the image for printing, putting drops on paper, and ink/media interaction. We d...

A photo-crystallographic study of Fe(btr)2(NCS)2.H2O was performed in order to describe the modification of structures and charge densities on going from the ground low spin (LS) state to the metastable high spin (HS) state during the LIESST phenomenon at 15K. Related photo-magnetic and spectroscopic measurements are also described. We show that at 15K, the thermally quenched and photo-induced ...

Acetylene-black paste without a light scattering layer was applied to meso-porous TiO2 photo-electrode films with a crystalline framework, a low residual carbon, and a tunable morphological pore size. The thermal-treated TiO2 photo-electrode films had an increased acetylene-black concentration with an increase in artificial pores and a decrease in residual carbon. The performance of dye-sensiti...

In this paper, a technique is presented to detect micro-cracks on photo-voltaic cells by infrared thermography. The originality of the system comes from the thermoelectric stimulation used to generate thermal transients at micro-crack locations. These thermal transient are picked-up by an infrared cameras for further detection.

The first experiments on trapped rotaxanes are presented, combining collision induced fragmentation and in-trap laser spectroscopy. The intrinsic optical properties of three rotaxanes and their non-interlocked building blocks (thread and macrocycle) isolated in a quadrupolar ion trap are investigated. The excitation and relaxation processes under thermal activation as well as under photo-activa...

Biocompatible gold nanoparticles (AuNPs) are particularly interesting for photo-thermal therapy (PTT) of cancer treatment because their ability to convert light into heating efficiently. Nevertheless, the random accumulation AuNPs in tissues, mainly determined by retention time bloodstream, is one main limiting factors use PTT applications. For this reason, efficient targeting and monitoring se...
