Electropolymerized Aptasensor for Femtogram‐Level Cytokine Detection

Advanced Materials, EarlyView.
Electropolymerization of 3‐amino‐ʟ‐tyrosine creates ultrathin, smooth, and chemically robust pALT nanofilms with accessible carboxyl functionalities for direct aptamer immobilization. Integrated with fiber‐optic SPR and OECT platforms, these interfaces enable IL‐6 detection down to 100 fg mL−1 and provide a versatile route to bioelectronic sensing ...

Dependence of Shock-Tube Boundary Layers on Shock Strength [PDF]

The Physics of Fluids, 1969
Using familiar considerations of vorticity transport, the essential behavior of shock-tube boundary layers is explicitly exhibited; the nearly constant functions that cannot be calculated analytically are evaluated numerically and compared with Mirels' correlations.

Dynamic Mechanical Loading Modulates Extracellular Vesicle Production and Cargo in Meniscus Fibrochondrocytes

Advanced Materials Interfaces, EarlyView.
Dynamic mechanical loading of outer meniscus fibrochondrocytes increases extracellular vesicle (EV) yield and alters EV composition. When applied to progenitor cells, these mechanically primed EVs modulate the expression of matrix‐related genes.

Study on propagation characteristics of shock waves during the leakage of a high-pressure hydrogen/methane mixture

工程科学学报
The transition from traditional fossil fuels to the widespread use of hydrogen energy marks a critical phase in energy evolution. Hydrogen/methane mixtures, serving as crucial carriers of hydrogen energy, play a key role in this process.

Numerical Simulation to Study the Effects of Riemann Problems on the Physical Properties of the Astrophysics Gas Dynamics

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017
In this work we run simulation of gas dynamic problems to study the effects of Riemann problems on the physical properties for this gas. We studied a normal shock wave travels at a high speed through a medium (shock tube).

A Cryopreservation‐Based Supply Chain Strategy for Extrusion Bioprinting in Space

Advanced Materials Technologies, EarlyView.
Extrusion bioprinting on crewed space platforms requires a bioink that stays functional along the logistic chain. Here, cells and biomaterial ink travel separately, the cells cryopreserved and the ink cold stored, and are combined only minutes before printing.

Soft Robotic Excretory Care Simulator for Nursing Education: Functional and Perceptual Biomimetics Approach

Advanced Robotics Research, EarlyView.
A soft robotic simulator is developed to replicate the digital removal of feces (DRF), a sensitive yet essential nursing procedure. Integrating soft actuators, sensors, and a realistic rectal model, the simulator balances functional fidelity with perceptual realism. Engineering evaluations and nurse feedback confirm its potential to enhance training in

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Wyznaczanie Energii Dostarczonej do Elektrycznej Rurki Uderzeniowej

Engineering Transactions, 1966
The present paper describes a method for determining the energy input in an electric shock tube based on the relations, obtained experimentally, between the intensity of current and the time in the discharge circuit including a shock tube or if the ...
