Spectrophotometry and structural analysis of 5 comets [PDF]
, 2002 We discuss the morphology and spectrophotometry of 5 comets visible in August, 2001. We decompose comae into coma profiles and azimuthally renormalized images, in which general and local features are quantitatively comparable. Comet 19P/Borrelly showed a strong gas fan toward the solar direction, but no detectable gas in the tail.

The Chemical Composition of the 30 Doradus Nebula Derived from VLT Echelle Spectrophotometry [PDF]
Astrophys.J. 584 (2003) 735-750, 2002 Echelle spectrophotometry of the 30 Doradus nebula in the LMC is presented. The data consists of VLT UVES observations in the 3100 to 10350 A range. The intensities of 366 emission lines have been measured, including 269 identified permitted lines of H 0, He 0, C 0, C+, N+, N++, O 0, O+, Ne 0, Ne+, S+, S++, Si 0 , Si+, Si++, Ar+, and Mg+.

Advanced Healthcare Materials, EarlyView.The ability of human induced pluripotent stem cells (hiPSCs) to model developmental processes makes them a promising source for engineering testicular tissues to study in vitro maturation and sperm production. This work describes the first hiPSC‐derived testicular model and shows that it captures functional aspects of prepubertal testicular tissues ...

Advanced Healthcare Materials, EarlyView.This study investigates nanoscale temperatures generated by photoexcited gold nanostars and their correlation with microscale thermal damage at the cellular level. Using X‐ray absorption spectroscopy and confocal microscopy in 3D cancer spheroids, it assesses localized heating effects and examines tumor cell structure and integrity, offering insights ...

Thermal Lens Spectrophotometry
The Review of Laser Engineering, 1982 Abstract A thermal lens effect induced under laser irradiation is useful for the detection of very small absorptions. This forms the basis of a new technique which is becoming increasingly important as a tool for ultratrace analysis.

Determination Of Sun Protection Factor By Uv-Vis Spectrophotometry
, 2016 Background: Sunscreen products contain active ingredients that can absorb, reflect or scatter the sunlight, depending on their nature. We can evaluate the effectiveness of a sunscreen by determining the sun protection factor (SPF).
