Multimodal Soft Surgical Robots Enabled by Eco‐Degradable, Sterilizable Polymers and Transient Electronics

Advanced Functional Materials, EarlyView.
A compostable PGS soft surgical robot with interchangeable modules integrates transient Mo tactile and Si thermal sensors for dual feedback. The device preserves its function after clinical‐grade sterilization, demonstrates stable actuation and cardiac tissue grasping with real‐time in vivo pulsatile monitoring, and biodegrades post‐use with soil‐safe,

Numerical and analysis effects of rectangular prism rough beds on hydraulic jumps in open channels

AIP Advances
Hydraulic jumps are characterized by intense turbulence and substantial energy dissipation in open channel flows or stilling basins. This study utilizes the Flow-3D hydraulic computational model, integrating the renormalization group k-ε turbulence model

Analytical solution to problems of hydraulic jump in horizontal triangular channels

Ain Shams Engineering Journal, 2013
A hydraulic jump is formed in a channel whenever supercritical flow changes to subcritical flow in a short distance. It can be used in triangular ditch irrigation to raise the downstream water surface.

Transfer Printing and Reconfiguration of Soft Electronics Using Digital Microfluidics and Laser Machining

Advanced Functional Materials, EarlyView.
This paper presents a digital microfluidics‐based technique for transferring and reconfiguring soft nanomembranes. Laser‐machined nanothin membranes are picked up, transported, and aligned via tailored surface tension and the actuation of water droplets, enabling the development of flexible electronics, the integration of functional materials on 3D ...

Dissipation of mechanical energy over spillway through counter flow

Građevinar, 2018
A reversed flow in form of cross-jet serves for dissipation of the energy of flow after spillway. Parameters influencing characteristics of hydraulic jump are systematically investigated via a physical model. The obtained results reveal that the reversed

Weakly undular hydraulic jump: Effects of friction

, 2014
The undular hydraulic jump is a transitional flow phenomenon where both streamline curvature and frictional effects are important. In the past, streamline curvature effects were treated with the Boussinesq equations for the potential flow approach ...

Pickering‐Engineered Microparticles for Magnetically Guided Motion and Light‐Triggered Catalysis

Advanced Functional Materials, EarlyView.
Magnetically responsive wax microparticles stabilized by hematite cubes through the Pickering emulsification strategy are developed, showing controlled size, motion, and light‐activated catalytic activity. Annealing under a magnetic field enhances their mobility and steering.

A laboratory Study on the Effect of Perforated Sills in Stilling Basin on the Secondary Depth and Length of the Roller of the Hydraulic Jump

علوم آب و خاک, 2018
The purpose of this study was to evaluate two perforated sills in the stilling basin and their impact on characteristics of the hydraulic jump, such as the length of the roller of hydraulic jump, decrease in the secondary depth of the hydraulic jump, and

Estimating the effect of sand-roughened bed on hydraulic jump characteristics using heuristic models

Results in Engineering
The hydraulic jump occurs in open channels and downstream of hydraulic structures because these features change the flow regime from super-critical to sub-critical. To prevent downstream channel erosion and guarantee the construction of a hydraulic jump,
