Process System Hydraulics [PDF]

, 2002
An analysis of hydraulic characteristics of the reactor plenum and the geometry of the permanent tube slots indicates the effect of the plenum pressure gradient on flow is substantially less than has been used previously to determine process water flows from cumulative fuel assembly resistances. This report details results of that study.

Enhanced Endoscopic Internal Drainage of Gastric Abscess Through Additively Manufactured Stents

Advanced Healthcare Materials, EarlyView.
Postoperative gastric leaks are often treated with off‐label biliary double‐pigtail stents, yet conventional extruded designs are not optimized for leak anatomy, can migrate, and may limit abscess evacuation. PETALS is introduced to optimize transmural drainage geometry and enable patient‐specific 3D‐printable stents.

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Simulation Analysis of an Electric Locomotive with a Hydraulic Wheelset Guidance System for Improved Performance in Curved Tracks

Machines
A reduction of forces acting between the railway track and the vehicle is one of the key issues in the design of modern rolling stock. Because the capabilities of reducing wheel–rail contact forces in track curves by conventional methods are encountered ...

A Biochar‐Based Composite Hydrogel Microenvironment for Enhanced Biocatalysis

Advanced Materials, EarlyView.
This work presents the synthesis of a polyacrylamide hydrogel wherein biomass‐derived biochar is co‐encapsulated with the enzyme horseradish peroxidase (HRP). The resulting composite hydrogel possesses balanced electron‐rich and electron‐deficient domains, creating an optimal microenvironment that concentrates both hydrogen peroxide and phenol ...

Elastomeric Micro‐Balloons for Remote Control of Cerebral Blood Flow and Real‐Time In vivo Imaging of Rodent Brain Response to Hypoperfusion

Advanced Materials, EarlyView.
This study reports the fabrication of MRI‐compatible elastomeric micro‐balloons via a multi‐step bubble casting process, where the monolithic elastomeric wall is selectively stiffened for reversible and controlled inflation and elasticity, depending on the target vessels for graded occlusion of cerebral arteries.
