Phases and Dynamics of an Impurity Immersed in One-Dimensional Quantum Droplets [PDF]

Entropy
We explore the ground-state properties of a single impurity immersed in a one-dimensional quantum droplet medium formed by a two-component Bose mixture. Relying on ab initio simulations, we demonstrate that tuning the impurity–droplet interactions allows

Bacterial turbulence drives interfacial waves and shape dynamics in phase-separated droplets [PDF]

Nature Communications
Liquid-liquid phase separation is important across biology, physics, and materials science. Although usually studied at equilibrium, active components-such as motor proteins, enzymes, and synthetic microswimmers-are increasingly recognized as key players

Modification of Pesticide Sprayer to Suit the Orchard Trees [PDF]

Journal of Soil Sciences and Agricultural Engineering, 2021
This study aims to develop a commonly used sprayer in the Egyptian farms (gun sprayer, Alcon Motori) adapted for orchard fields. The main aspect of the modified sprayer was the ability to move nozzles at vertical reciprocating motion NVRM which improves ...

Effect of Nozzle Type and Adjuvants on Spray Coverage on Apple Leaves

Agronomy, 2021
Three non-ionic adjuvants, Agral, Silwet, and Greemax, at three concentrations, were applied on apple leaves with the use of hollow cone nozzles (TR) and air-induction nozzles (ID) to verify the assumption that adjuvants may improve spray coverage ...

Modeling of Masked Droplet Deposition for Site-Controlled Ga Droplets

Nanomaterials, 2023
Site-controlled Ga droplets on AlGaAs substrates are fabricated using area-selective deposition of Ga through apertures in a mask during molecular beam epitaxy (MBE). The Ga droplets can be crystallized into GaAs quantum dots using a crystallization step

Spray solution deposition and Asian rust control in soybean cultivars

Revista Brasileira de Engenharia Agrícola e Ambiental, 2021
The control of Asian soybean rust depends on fungicide efficacy and the application technology; however, the leaf architecture of soybean cultivars may also interfere in disease control.

Modeling of Al and Ga Droplet Nucleation during Droplet Epitaxy or Droplet Etching

Nanomaterials, 2021
The temperature dependent density of Al and Ga droplets deposited on AlGaAs with molecular beam epitaxy is studied theoretically. Such droplets are important for applications in quantum information technology and can be functionalized e.g., by droplet ...

Comparison of water-sensitive paper, Kromekote and Mylar collectors for droplet deposition with a visible fluorescent dye solution

Journal of Plant Protection Research, 2020
The study was conducted at the University of Nebraska Pesticide Application and Technology Laboratory in North Platte, Nebraska in July 2015. Two application volume rates (100 and 200 l · ha−1) and three nozzle types (XR, AIXR, TTI) were selected at ...
