Fluorescent Organic Nanoparticles (FONs), prepared by self-aggregation of dedicated dyes in water, represent a promising green alternative to the toxic quantum dots (QDs) for bioimaging purposes. In the present paper, we describe the synthesis and photophysical properties of new dipolar push-pull derivatives built from thieno[3,2-b]thiophene as a π-conjugated bridge that connects a triphenylami...

Abstract The formulation of the time-dependent close-coupling method is extended so that energy and angle differential cross sections for the double photoionization of helium may be obtained. The fully quantal method now yields absolute total integral, energy differential, and angle differential cross sections. A detailed comparison is made with the absolute synchrotron measurements of Bräuning...

The present study aimed to investigate the possibility of reducing energy content in emulsion type sausages by replacing fat with inulin. In the manufactured product, the fat content was reduced to 6%-18% and replaced by inulin and water. The quality of the resulting product was determined by chemical and texture profile analyses (TPA), color measurement and sensory evaluation. The results show...

AIM To study bone turnover following renal transplantation using a panel of biochemical markers and to correlate the results with both areal and volumetric bone mineral density (BMD). PATIENTS A total of 31 patients aged 18.1 years were transplanted 5.4 years before this study. Control patients (n = 31) were age and gender matched. METHODS In addition to measurement of biochemical markers, ...

1. We have examined the relationship between broadband ultrasound attenuation in the os calcis and measurements of bone mineral in the distal forearm and lumbar spine of normal and postmenopausal osteoporotic women. 2. Values of broadband ultrasound attenuation in postmenopausal women with vertebral osteoporotic fractures were significantly lower (35%) than in normal pre- and peri-menopausal wo...

Two-photon absorption (TPA) and other nonlinear interactions of molecules with time-frequency-entangled photon pairs (EPP) has been predicted to display a variety fascinating effects. Therefore, their potential use in practical quantum-enhanced molecular spectroscopy requires close examination. This paper presents tutorial style detailed theoretical study one- two-photon by molecules, focusing ...

A neutral (1N) and a cationic (1C) bridged-triphenylamine tetramer with large two-photon absorption (TPA) cross sections of 4340 GM ( 1N toluene) and 4150 GM (1C in methanol) were synthesized.

Herein, a triphenylamine derivative ( TP-3PY ) possessing 4-(4-bromophenyl)pyridine (PY) as electron-accepting group and tris[p-(4-pyridylvinyl)phenyl]amine (TPA) with large two-photon absorption cross-sections electron-donating was obtained, which showed intense at visible...
