Miniature Soft Robot With Magnetically Reprogrammable Surgical Functions

open access: yesAdvanced Materials, EarlyView.
Miniature soft robots have great prospects to revolutionize minimally invasive treatments. Here we present a miniature soft robot, which can be reprogrammed to perform five surgical functionalities with six‐degrees‐of‐freedom motions. This soft robot can prospectively make minimally invasive surgery considerably safer and painless, and enable ...

Optimization and Experimental Study on Autonomous Inflow Control Device in Heavy Oil Reservoirs

open access: yesShiyou jixie, 2022
Bottom water tends to taper into the root of horizontal wells and the parts with good physical properties in the development of oil and gas reservoirs,which greatly affects the production effect of horizontal wells.Therefore,the autonomous inflow control

Dexime: A Selectively Enzyme‐Degradable Hydrogel for Protein Therapeutic Release

open access: yesAdvanced Materials, EarlyView.
A dextrin‐oxime hydrogel (dexime) is produced using ketone or aldehyde modified dextrin and tetra‐oxyamine modified poly(ethylene glycol). The rheological and mechanical properties of dexime are tunable. Dexime is injectable, cytocompatible, hydrolytically stable, and selectively degradable by α‐amylase.

Two-phase flow meter for determining water and solids volumetric flow rate in vertical and inclined solids-in-water flows

open access: yes
Multiphase flow can be defined as the simultaneous flow of a stream of two or more phases. Solids-in-water flow is a multiphase flows where solids and liquid are both present. Due to the density differences of the two phases, the results for such flow is

Oil-gas-water three-phase upward flow through a vertical pipe: Influence of gas injection on the pressure gradient

open access: yes, 2012
LtdAn experimental study of three-phase flow in a vertical pipe with 50 mm diameter has been carried out. The experiments were conducted under the input superficial phase velocity: water from 0 to 0.885 m/s, oil from 0 to 0.90 m/s and gas from 0 to 0.85 ...

Droplet Electricity Generators With Maximized Energy Collection Zone Enabled by Aloe‐Inspired Midrib and Cuticle

open access: yesAdvanced Materials, EarlyView.
An Aloe‐pinspired droplet electricity generator (A‐DEG) overcomes the limited energy collection zone of conventional DEGs by guiding impact droplets through a channeling midrib and artificial cuticle. The channeling midrib induces uni‐directional droplet spreading, while the artificial cuticle on the midrib further reinforces this behavior through its ...

Active control of hydrodynamic slug flow [PDF]

open access: yes, 2013
Multiphase flow is associated with concurrent flow of more than one phase (gas-liquid, liquid-solid, or gas-liquid-solid) in a conduit. The simultaneous flow of these phases in a flow line, may initiate a slug flow in the pipeline. Hydrodynamic slug flow
