Hydraulic Characteristics of Free Overfall in a Steep and Rough Rectangular Channel

open access: yes工程科学与技术, 2019
In the rectangular open channel, the free overfall can be used as the discharge measure device. In the channel project, the channel usually has the features as a rough and steep one.

Fault‐Controlled Permeability: A Key Parameter in Geothermal Electricity Production Assessment

open access: yesTerra Nova, EarlyView.
ABSTRACT Geothermal energy is central to the global green energy transition, but its development has long focused on regions with positive thermal anomalies. Through a semi‐quantitative global‐scale review and spatial analysis of 361 geothermal sites, we show that 56.2% of global geothermal electricity production occurs in regions with thermal ...

Prediction of transonic flutter for a supercritical wing by modified strip analysis and comparison with experiment

open access: yes, 1981
Use of a supercritical airfoil can adversely affect wing flutter speeds in the transonic range. As adequate theories for three dimensional unsteady transonic flow are not yet available, the modified strip analysis was used to predict the transonic ...

Seasonal Restructuring of Microbial Communities and Resistomes in the Shitalakshya River, Bangladesh Revealed by Shotgun Metagenomics

open access: yesMicrobiologyOpen, Volume 15, Issue 4, August 2026.
Dry‐season pollutant concentration drives microbial restructuring in Bangladesh's Shitalakshya River, shifting communities from Myroides to stress‐tolerant genera while enriching metal resistance genes and efflux pumps, revealing non‐antibiotic co‐selection as a key driver of antimicrobial resistance in urban waters.

Tunable Natural Deep Eutectic Solvents‐Driven Fractionation of Olive Pomace in an Integrated Biorefinery: Linking Lignin Structural Tailoring to Carbohydrate Valorization and Biopolymer Production

open access: yesChemSusChem, Volume 19, Issue 13, 14 July 2026.
Microwave‐conditioned olive pomace was fractionated with deep eutectic solvents (DESs) spanning acidic, neutral, alkaline, and chemo‐enzymatic regimes. The alkaline DES provided the best balance between delignification and carbohydrate preservation, yielding a fermentable glucose/xylose stream suitable for Haloferax mediterranei fermentation and poly(3‐

Comparison of numerical schemes for modelling supercritical and transcritical flows along urban floodplains

open access: yes, 2011
Many urban floodplains have irregular geometry due to different obstacles and slope conditions. This may change the flow regime from subcritical to supercritical flow conditions, and vice versa. The 1D and 2D shallow water equations

Batteries From Reused, Recycled, and Surplus Materials

open access: yesAdvanced Sustainable Systems, Volume 10, Issue 7, July 2026.
Batteries can become more circular by combining reuse, direct recycling, metallurgical recovery, and material sourcing from industrial surplus streams. This Review highlights how recycled and waste‐derived metals, carbons, polymers, electrolytes, and active materials can be reintegrated into current and emerging batteries, while emphasizing design ...

Internal Tide Reflection and Turbulent Mixing on the Continental Slope

open access: yes
Observations of turbulence, internal waves, and subinertial flow were made over a steep, corrugated continental slope off Virginia during May–June 1998. At semidiurnal frequencies, a convergence of low-mode, onshore energy flux is approximately balanced ...

Optimal model‐based design of experiments for parameter precision: Supercritical extraction case

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 7, Page 3775-3795, July 2026.
Abstract This study investigates the process of chamomile oil extraction from flowers. A parameter‐distributed model consisting of a set of partial differential equations is used to describe the governing mass transfer phenomena in a cylindrical packed bed with solid chamomile particles under supercritical conditions using carbon dioxide as a solvent ...
