Research Progresses of Flash Evaporation in Aerospace Applications

open access: yesInternational Journal of Aerospace Engineering, Volume 2018, Issue 1, 2018., 2018
Liquid is overheated and evaporated quickly when it enters into the environment with lower saturation pressure than that corresponding to its initial temperature. This phenomenon is known as the flash evaporation. A natural low‐pressure environment and flash evaporation have unique characteristics and superiority in high altitude and outer space ...

Transitional shockwave/boundary layer interaction experiments in the R2Ch blowdown wind tunnel

open access: yesExperiments in Fluids, 2022
Transitional Shockwave/Boundary Layer Interactions (SBLI) is studied experimentally. Experiments are conducted on a hollow-cylinder flare model in the R2Ch blowdown facility at a Mach number of 5 for three different Reynolds numbers in the transitional regime.

Susquehanna Shale Hills Critical Zone Observatory: Shale Hills in the Context of Shaver's Creek Watershed

open access: yesVadose Zone Journal, Volume 17, Issue 1, Page 1-19, 2018., 2018
Core Ideas Studying the critical zone requires targeted research on water, energy, gas, solutes, and sediments. The SSHCZO targets a 165‐km2 watershed on sedimentary rocks in the northeastern United States. One SSHCZO subcatchment, Shale Hills, provides extraordinary data describing a shale CZ.

Wind Tunnel Testing on Start/Unstart Characteristics of Finite Supersonic Biplane Wing

open access: yesInternational Journal of Aerospace Engineering, Volume 2013, Issue 1, 2013., 2013
This study describes the start/unstart characteristics of a finite and rectangular supersonic biplane wing. Two wing models were tested in wind tunnels with aspect ratios of 0.75 (model A) and 2.5 (model B). The models were composed of a Busemann biplane section.

Thermal effects influencing measurements in a supersonic blowdown wind tunnel

open access: yesThermal Science, 2016
During a supersonic run of a blowdown wind tunnel, temperature of air in the test section drops which can affect planned measurements. Adverse thermal effects include variations of the Mach and Reynolds numbers, variation of airspeed, condensation of moisture on the model, change of characteristics of the instrumentation in the model, et ...

Atomic Layer Deposition in Transistors and Monolithic 3D Integration

open access: yesAdvanced Functional Materials, Volume 36, Issue 41, 21 May 2026.
Transistors are fundamental building blocks of modern electronics. This review summarizes recent progress in atomic layer deposition (ALD) for the synthesis of two‐dimensional (2D) metal oxides and transition‐metal dichalcogenides (TMDCs), with particular emphasis on their enabling role in monolithic three‐dimensional (M3D) integration for next ...

Control of Reynolds number in a high speed wind tunnel [PDF]

open access: yesJournal of Aerospace Technology and Management, 2009
A conceptual control model for the Reynolds number test based on isentropic relations was established for the supersonic wind tunnel. Comparison of the system response of the model simulation and the actual wind tunnel test data was made to design the ...

Plant Responses to Anomalous Heat and Drought Events in the Sonoran Desert

open access: yesGlobal Change Biology, Volume 31, Issue 5, May 2025.
What are the impacts of region‐wide heat and drought events on desert vegetation? This multi‐scale assessment shows that columnar cacti and succulent trees show acute plant stress across the Sonoran Desert. The expected increased frequency of heat and drought events will likely have landscape‐wide impacts that could fundamentally reshape populations of

Infra‐Through Ultrasonic Piezoelectric Acoustic Vector Sensor Particle Rejection System

open access: yesSmart Materials Research, Volume 2012, Issue 1, 2012., 2012
Sensor elements which employ fine filaments are often vulnerable to particulate fouling when used in certain operational field conditions. Depending on the size, attraction level, thermal and electrical conduction, and charge accumulation properties of the particles, erroneous readings can be easily generated in such “dirty” environments.

Tree demographics and soil charcoal evidence of fire disturbances in an inaccessible forest atop the Mount Lico inselberg, Mozambique

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 1, Page 229-244, January 2025.
Highland forests of Mozambique have been strongly modified by human activities for millennia. Some highlands have sheer rock cliffs and are highly inaccessible to people and appear relatively undisturbed. Evidence from the forest and soils of inaccessible Mount Lico show that the fire regime has changed over the recent millennia.
