Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

XDrift—An R package to simulate spatially explicit pesticide spray-drift exposure of non-target-species habitats at landscape scales

SoftwareX, 2020
Authorization of pesticides in the European Union is based on a risk assessment that aims at prevention of unacceptable ecological effects. This ecological risk assessment increasingly requires data and tools to base informed decisions on a more ...

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Influence of speed and angle of spraying on area coverage and drift in the potato production [PDF]

Journal of Central European Agriculture
This study investigated the influence of travel speed (6 and 10 km/h) and spray angle (-30°, 0° and +30°) on leaf surface coverage (LSC), on the area not treated (drift) and on droplet size. The leaf surface coverage, size and number of droplets, as well

Self‐Cleaning Sensor Surfaces for Long‐Term Environmental Monitoring

Advanced Engineering Materials, EarlyView.
Long‐term use of unattended outdoor sensors without soiling or biofouling is achieved through generation of a micro‐ and nanorough cuvette surface by combing hydrophobic nanoparticles with fluorinated polymers, crosslinked and surface‐attached through CHic chemistry. The coating demonstrates self‐cleaning behavior and prolonged outdoor stability, which

Materials‐Driven Additive Manufacturing for Electrical Machines: Qualification‐Oriented Design Beyond Geometric Freedom

Advanced Engineering Materials, EarlyView.
This perspective reframes additive manufacturing for electrical machines as a qualification‐limited materials and architecture design problem. It links process–structure–property–performance relationships to magnetic, conducting, dielectric, and thermal property windows, highlighting where AM can enable segmented magnetic circuits, permanent magnet ...

Predicting Spray Drift from Backpack and UTV Spraying

Transactions of the ASABE, 2018
Abstract. This article summarizes the development and predictions of a Lagrangian-based computer model applied to recent field data on backpack and utility vehicle spraying. Model agreement with data supports the usefulness of the model for the tested conditions, and provides the USDA Forest Service and other agencies with a simple-to-use numerical ...
