Effect of Electric Field on Growth Kinetics, Morphology and Wettability of Flame‐Deposited Carbon Nanoparticle Coatings

Advanced Materials Interfaces, EarlyView.
A novel electric field‐assisted thermophoretic flame synthesis process enables rapid deposition of carbon nanoparticle films with tunable wettability. Applying a negative voltage during flame exposure accelerates growth, increases surface roughness, and alters morphology.

Bacterial‐Responsive and Dye‐Selective Janus Membranes via Laser‐Directed Fluorinated Graphene Interfaces

Advanced Materials Interfaces, EarlyView.
This work highlights laser‐engineered wettability switching of fluorine‐doped laser‐induced graphene (F‐LIG) for antibacterial, thickness‐tunable, dye‐selective filtration. Precise CO2‐laser patterning modulates surface roughness and hydrophobicity, suppressing bacterial adhesion and disrupting cell membranes, while Janus F‐LIG/F‐PPI structures enable ...

Complementarity in Phenolic Compounds and the Antioxidant Activities of Phaseolus coccineus L. and P. vulgaris L. Landraces

Foods, 2019
Phaseolus vulgaris L. is one of the most consumed and documented legumes in regard to its grain composition, but little is known about P. coccineus L. To evaluate and compare the phenolic compound content and antioxidant activity between landraces of P ...

On the use of ultraviolet photography and ultraviolet wing patterns in butterfly morphology and taxonomy [PDF]

, 2000
In a series of feeding experiments we found that, depending on the larval food plant species or part of food plant ingested, individuals of the blue butterfly Polyommatus icarus (Lycaenidae) exhibit broad variation of wing patterns in the ultraviolet (UV)

Extrasolar Planets and Their Host Stars

, 2017
In order to understand the exoplanet, you need to understand its parent star. Astrophysical parameters of extrasolar planets are directly and indirectly dependent on the properties of their respective host stars.

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.
