Woody Vegetation Dynamics Beyond the Treeline: Identifying Limiting Processes and Their Tipping Points

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Illustration of temporal trends in Arctic and alpine woody vegetation under changing growth conditions (summer temperature and winter snowpack). Upper panel: example of shrub expansion in southern France (photograph included). Greening is detected via increasing NDVI (Normalized Difference Vegetation Index).

Effect of airstream velocity on mean drop diameters of water sprays produced by pressure and air atomizing nozzles [PDF]

, 1977
A scanning radiometer was used to determine the effect of airstream velocity on the mean drop diameter of water sprays produced by pressure atomizing and air atomizing fuel nozzles used in previous combustion studies.

Characterization of Droplet Formation in Ultrasonic Spray Coating: Influence of Ink Formulation Using Phase Doppler Anemometry and Machine Learning

Advanced Materials Technologies, Volume 11, Issue 15, 7 August 2026.
This study explores how machine learning models, trained on small experimental datasets obtained via Phase Doppler Anemometry (PDA), can accurately predict droplet size (D32) in ultrasonic spray coating (USSC). By capturing the influence of ink complexity (solvent, polymer, nanoparticles), power, and flow rate, the model enables precise droplet control

Modeling the separation of water‐in‐oil emulsions in continuously fed gravity settlers using millifluidic experiments

AIChE Journal, Volume 72, Issue 8, August 2026.
Abstract Emulsion separation remains a persistent challenge in chemical and process industries due to the metastable nature of dispersed droplets. In gravity separators, the overall separation rate is governed by the formation of a densely packed zone (DPZ) of deforming and coalescing droplets that mediates between the dispersed and continuous phases ...

Prediction of holdup and drop size distribution in a disc-doughnut pulsed column with tenova kinetics internals for the water-Alamine 336 system [PDF]

, 2018
Tenova Pulsed Column Kinetics Internals (TPC-KIs) are a newly designed type of pulsed column internals with a novel structure that is expected to achieve less back-mixing, higher holdup and improved mass transfer.

Saturated flow boiling in small- to micro- diameter metallic tubes: Experimental results and modeling [PDF]

, 2008
Some results of a long-term study of flow boiling patterns, heat transfer rates and pressure drop of R134a at pressures of 6-14 bar in five vertical stainless steel tubes of internal diameter 4.26, 2.88, 2.01, 1.1 and 0.52 mm are presented in this paper.

Connectivity Between Primary and Secondary Subglacial Drainage Subsystems Beneath a Land‐Terminating Outlet Glacier of the Greenland Ice Sheet

AGU Advances, Volume 7, Issue 5, August 2026.
Abstract The evolution and connectivity of subglacial drainage systems control basal sliding and therefore modulate ice motion, yet direct observations of these systems remain limited. Here, we investigate hydraulic connectivity and its influence on ice motion at Isunnguata Sermia, a large land‐terminating outlet glacier of the Greenland Ice Sheet.

Thermal, Structural, and Molecular Characterization of a Model Cereal–Milk Infant Formula: Impact of Ultrasound Pre‐Treatment Prior to Spray Drying

Food Science &Nutrition, Volume 14, Issue 7, July 2026.
This study evaluated the efficacy of an ultrasound pre‐treatment applied to a complex cereal–milk infant formula prior to conventional spray drying to mitigate inherent stickiness and yield challenges. Acoustic cavitation (30–90 s) significantly reduced suspension viscosity and improved atomization efficiency, elevating powder recovery yield from 12 ...

Controlling Pickering Emulsion Architecture Through Temperature‐Directed Nanoparticle‐Surfactant Assembly

Particle &Particle Systems Characterization, Volume 43, Issue 7, July 2026.
Temperature is used as a simple control parameter to direct interfacial assembly in particle‐surfactant Pickering emulsions. By combining APTES‐functionalized silica nanoparticles with oil‐soluble C18 surfactants, emulsions are switched between weakly stabilized droplets, rigid interfacial films, and capsule‐ or gel‐like particle architectures ...

Time-Resolved Pulsed Spray Drop Sizing At Elevated Pressures

, 1986
An experimental program was conducted to measure drop sizes in pulsed sprays for diesel and fuel-injected spark ignition engine applications. A forward-scattering unit was designed with a high-speed data acquisition system to permit the measurement of ...
