Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres

open access: yesAdvanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.

Comparative Experimental Efficiency of Solar Water Heating Systems With Enhanced Thermal Performance: A Review

open access: yesEnergy Science &Engineering, Volume 14, Issue 6, Page 3056-3072, June 2026.
This review presents a comparative analysis of experimental studies aimed at improving the thermal efficiency of solar water heating (SWH) systems. Various enhancement techniques, including nanofluids, phase change materials, optimized collector designs, and hybrid photovoltaic–thermal systems, are evaluated based on their impact on system performance ...

An Impact-Echo Experimental Approach for Detecting Concrete Structural Faults

open access: yesAdvances in Civil Engineering, 2021
For the current problem of detection of grouting defects in posttensioned prestressed concrete members, the paper takes a single-layer arrangement of prestressed pipes as the object of study.

CFD‐Based and Control‐Oriented Modeling of a Counterflow Heat Exchanger With Utilization of Parameter Identification

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Counterflow heat exchangers (CHXs) thermally couple consumers and producers to a district heating network (DHN). Fluctuating loads and control actions naturally lead to unsteady operation conditions of the network and its components, posing a challenge for DHN models and CHX parameterizations based on Nusselt correlations that assume steady ...

Urban Waters, Unseen: The Hydrology of Informal Settlements Must Not Be Ignored

open access: yesWater Resources Research, Volume 62, Issue 6, June 2026.
Abstract Informal settlements—home to more than 1 billion people worldwide—remain largely invisible in urban hydrological science. Despite their density, structural complexity, and distinctive water pathways, these neighborhoods are routinely omitted from flood models, drainage assessments, and water‐resource analyses due to data gaps and limitations ...

Controlling the Acoustic Resonance in a Corrugated Flow Pipe [PDF]

open access: yes, 2013
A new experimental study, aimed at investigating the coupling between the flow in a corrugated pipe, the acoustically generated flow oscillations, and the emitted resulting noise is carried out. Hot-wire anemometry, Particle Image Velocimetry, and microphone measurements are associated to characterize the flow.

Conspecific density and reproductive trade‐offs govern population response to climate in a clonal wildflower

open access: yesJournal of Ecology, Volume 114, Issue 6, June 2026.
Our results demonstrate that interactive effects of clonal reproduction and intraspecific density are important contributors to plant demography and that high local density increases the negative impact of drought on population growth rates. Abstract Making predictions about the persistence of plant populations under climate change requires explicitly ...
