The role of charge relaxation in electrified tip streaming
(AIP Publishing, 2023-01-24)
We study experimentally and numerically the onset of tip streaming in an electrified droplet. The experiments show that, for a sufficiently small dimensionless conductivity, the droplet apex oscillates before ejecting a ...

Strategies for the Biofunctionalization of Straining Flow Spinning Regenerated Bombyx mori Fibers
(MDPI, 2022)
High-performance regenerated silkworm (Bombyx mori) silk fibers can be produced efficiently through the straining flow spinning (SFS) technique. In addition to an enhanced biocompat-ibility that results from the removal ...

Electrokinetic modelling of cone-jet electrosprays
(Cambridge University Express, 2023)
The physics of electrospray has been subject to an intense debate for three decades regarding the ultimate electrokinetics that determines the electric current and the size of the emitted droplets in the steady Taylor ...

Theory of the jets ejected after the inertial collapse of cavities with applications to bubble bursting jets
(American Physical Society, 2023)
The dynamics of the axisymmetric jets originated from the bursting of bubbles in a liquid of density ρ, viscosity μ, and interfacial tension coefficient σ can be rationalized as a two-stage process in which, initially, the ...

Design of a Soil Cutting Resistance Sensor for Application in Site-Specific Tillage
(MDPI - Open Access Publishing, 2013)
One objective of precision agriculture is to provide accurate information about soil and crop properties to optimize the management of agricultural inputs to meet site-specific needs. This paper describes the development ...

The high-throughput atomization of polymer solutions for fiber synthesis in a single step aided with corona ionizers
(Nature Publishing, 2023)
Polymer microfibers are ubiquitous structures across virtually all technological fields. Their applications include, for instance, filter media, tissue regeneration, wound healing and dressing, and reinforcement materials. ...

Energy Efficiency in Greenhouse Evaporative Cooling Techniques: Cooling Boxes versus Cellulose Pads
(MDPI, 2014)
Evaporative cooling systems using a combination of evaporative pads and extractor fans require greenhouses to be hermetic. The greatest concentration of greenhouses in the world is located in southeast Spain, but these ...

Tackling unbalanced datasets for yellow and brown rust detection in wheat
(Frontiers, 2024-05)
This study evaluates the efficacy of hyperspectral data for detecting yellow and brown rust in wheat, employing machine learning models and the SMOTE (Synthetic Minority Oversampling Technique) augmentation technique to ...

Role of liquid viscosity and of air entrapped on the splashing of drops impacting over superhydrophobic substrates
(American Physical Society, 2022-09)
Here we analyze the splash transition of drops of liquids with different viscosities impacting normally over different types of rough superhydrophobic substrates, finding that the velocity for the splash transition, V∗, ...

Amplification of Supersonic Microjets by Resonant Inertial Cavitation-Bubble Pair
(American Physical Society, 2024-03)
We reveal for the first time by experiments that within a narrow parameter regime, two cavitation bubbles with identical energy generated in antiphase develop a supersonic jet. High-resolution numerical simulation shows a ...
