3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

open access: yesAdvanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

A comparative study for the impact performance of shaped charge JET on UHPC targets

open access: yesDefence Technology, 2019
With the development of two-stage munitions (a precursor shaped charge (SC) and a following kinetic energy projectile) to attack the hard concrete targets, as well as the increasing applications of ultra-high performance concrete (UHPC) in both civil and

Design Optimization and Mechanism Analysis of Water Jet-Type Inter-Plant Weeding Device for Water Fields

open access: yesAgronomy, 2023
Existing rice inter-plant weed control devices have difficulty achieving inter-plant weed control in one pass. Due to the complex environment of paddy fields, these devices have a low weed removal rate and high seedling damage rate, making it difficult ...

Modelling rain drop impact on offshore wind turbine blades [PDF]

open access: yes, 2012
The effects of rain and hail erosion and impact damage on the leading edge of offshore wind turbine blades have been investigated. A literature review was conducted to establish the effects of exposure to these conditions and also to investigate the ...

Numerical investigations on bubble-induced jetting and shock wave focusing: application on a needle-free injection [PDF]

open access: yes, 2019
The formation of a liquid jet into air induced by the growth of a laser-generated bubble inside a needle-free device is numerically investigated by employing the compressible Navier–Stokes equations.

Two Erosion Tests to Quantify Resistance to Erosion During Overflow: The Jet Erosion Test and the Overflow Test ()

open access: yes
This report presents three experimental devices for quantifying the resistance to external erosion of a dam or dike embankment during overflow. The first is the Jet Erosion Test initially developed at the Agricultural Research Service (ARS, USA), and currently used by GeophyConsult (France) and INRAE (France). The second experimental apparatus concerns

Meniscus Pixel Printing for Contact‐Lens Vision Sensing and Robotic Control

open access: yesAdvanced Functional Materials, EarlyView.
A visual‐sensing contact lens is enabled by meniscus pixel printing (MPP), which rapidly patterns a 200 µm perovskite photodetector pixel in 1 s without masks, vacuum processing, or bulky equipment. A deep‐learning‐based super‐resolution reconstructs sparse on‐lens signals into 80 × 80 high‐resolution visual information, while AI‐driven eye‐tracking ...

A prediction model for the slot depth of high pressure water jet

open access: yesResults in Physics, 2018
Coal mines in China are characterized by low permeability, and hydraulic slotting is an effective technique to increase the gas permeability of coal. However, the slot depth cannot be accurately determined, which results in the layout parameters of the ...

Speckle‐Engineered Upconversion Amplification in Nanoemulsion‐Templated Hydrogel Microdomes

open access: yesAdvanced Functional Materials, EarlyView.
Nanoemulsion‐confined PEGDA microdomes generate speckle‐like excitation fields that strongly amplify upconversion luminescence upon dehydration, enabling filter‐free visible readout with reversible on–off switching. DMD‐based lithography yields scalable, shape‐programmable arrays for moisture‐responsive displays and optical encryption.
