From Fiber Bundles to Architected Membranes: Triply Periodic Minimal Surface Architectures for Biohybrid Artificial Lungs

Advanced Materials, EarlyView.
Additively manufactured triply periodic minimal surface (TPMS) membranes offer an architecture‐driven alternative to hollow fiber bundles in artificial lungs. Multiphysics simulations and endothelialized prototypes show that the 3D‐printable membrane architecture improves gas exchange, blood flow distribution, and hemocompatibility, enabling ...

Hydraulic model for flood inundation in Diyala River Basin using HEC-RAS, PMP, and neural network

Open Engineering
The Diyala River Basin in Iraq is vital for water supply to residential, agricultural, and the Tigris River (with approximately 4.5 billion cubic meters annually), but it faces frequent floods and droughts due to reliance on rainfall.

Soft Skins With Reversible Thickness Morphing: Materials, Mechanisms, and Applications

Advanced Materials, EarlyView.
Evolution of electronic skin (e‐skin) technologies toward adaptive, multifunctional soft skins. Phase I highlights early rigid and discrete sensory interfaces. Phase II shows the transition toward flexible, stretchable, and large‐area e‐skin. Phase III captures the emergence of computational e‐skin.

Channel‐Spanning Logjams and Reach‐Scale Hydraulic Resistance in Mountain Streams

Geophysical Research Letters
Logjams create an upstream backwater of deepened, slower water, locally reducing bed shear stress. We compared hydraulic impact of logjam series across 37 geomorphically diverse reaches of mountain streams observed over 11 years in the US Southern ...

Joint calibration of Manning’s roughness and seepage in canals using NSGA-II for precision hydrodynamic modeling

Frontiers in Water
Based on field investigations in multiple irrigation districts, it was found that farmers frequently employ sandbag barriers or direct pumping to meet irrigation demands, disrupting irrigation schedules and destabilizing downstream water supply. The core

Understanding Operando Water Management in Hydroxide‐Exchange‐Membrane Fuel Cells

Advanced Materials Interfaces, EarlyView.
Effective water management is vital for high‐performance hydroxide‐exchange‐membrane fuel cells. Using a custom water‐flux station, this study quantifies how membrane thickness, microporous layers, and operating conditions dictate internal water transport.

Quantifying Chinook salmon habitat across flow regimes: high resolution modeling in Oregon’s Willamette river basin

Frontiers in Ecology and Evolution
The Santiam and McKenzie River basins of western Oregon provide critical habitat for federally listed Upper Willamette River Spring Chinook salmon (Oncorhynchus tshawytscha). Streamflows in each basin are regulated in part by high-head multi-purpose dams;

Eutectic Gallium‐Indium as a Potential Non‐Toxic Replacement in Mercury Intrusion Porosimetry

Advanced Materials Technologies, EarlyView.
A practical alternative to mercury intrusion porosimetry is presented using non‐oxidized eutectic gallium‐indium. An eGaIn Filling Station enables oxygen‐free preparation of standard penetrometers, and the resulting measurements faithfully reproduce pore‐size distributions and intrusion volumes measured with mercury across several standard reference ...

Shape Optimization and Hydraulic Characteristics Analysis of Unilateral Divergent Stilling Basin

Renmin Zhujiang
The spillway of Dongchong Reservoir adopts an engineering scheme of spillway step energy dissipation and downstream stilling basin underflow. However, due to the limitations of terrain and geological conditions, the width of the stilling basin is small ...
