Positive‐Tone Nanolithography of Antimony Trisulfide with Femtosecond Laser Wet‐Etching

Advanced Functional Materials, EarlyView.
A butyldithiocarbamic acid (BDCA) etchant is used to fabricate various micro‐ and nanoscale structures on amorphous antimony trisulfide (a‐Sb2S3) thin film via femtosecond laser etching. Numerical analysis and experimental results elucidate the patterning mechanism on gold (reflective) and quartz (transmissive) substrates.

Development and Validation of a Selective Method to Quantify Low-Molecular-Mass Flavan-3-ols in Grapes and Wines

Foods
Quantifying low-molecular-mass (LMM) flavanols in wines is relevant because these compounds, though typically minor, reflect flavanol structural composition (seed vs. skin contributions) and relate to cultivar and winemaking technique.

Multiscale Structuring of Hydroxyapatite via Two‐Photon Lithography of Nanocomposites

Advanced Functional Materials, EarlyView.
Hydroxyapatite scaffolds are of great interest in bone tissue engineering applications, ranging from 3D cell culture to regenerative medicine. Using two‐photon lithography of a transparent nanocomposite, hydroxyapatite microstructures with features ranging from submicron to centimeter‐scale are fabricated. This allows to mimic the natural bone geometry,

Determination of bud fertility as a simple method for the determination of harvesting volume in Vitis vinifera L. cv Tannat, using two pruning systems

OENO One, 2004
Bud fertility was estimated in two commercial vineyards of Vitis vinifera cv. Tannat in the southern region of Uruguay; it was carried out in two periods: 1983-1986 (essay A) and 2001,2002,2003 (essay B).

Natural Gums in Drug-Loaded Micro- and Nanogels

Pharmaceutics, 2023
Gums are polysaccharide compounds obtained from natural sources, such as plants, algae and bacteria. Because of their excellent biocompatibility and biodegradability, as well as their ability to swell and their sensitivity to degradation by the colon ...

Three‐dimensional Antimony Sulfide Based Flat Optics

Advanced Functional Materials, EarlyView.
This work presents the development of a grayscale electron beam lithography (g‐EBL) method for fabricating antimony trisulfide (Sb2S3) nanostructures with customizable 3D profiles. The refractive index of g‐EBL patterned Sb2S3 is determined based on the synergy of genetic algorithm and transfer matrix method.
