Restoring joint homeostasis: A dynamically adaptive meniscal scaffold prevents osteoarthritis by replicating native biomechanics

open access: yesBMEMat, EarlyView.
This work establishes a paradigm shift from static structural mimicry to dynamic functional replication. By restoring the native “compression‐to‐tension” mechanism, the scaffold ensures robust mechanical stability and superior chondroprotection.

Monoclonal Antibodies; Detection Tools for Wheat Alpha‐Amylase Proteins

open access: yesCereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Expression of alpha‐amylase proteins during germination or other physiological events may lower grain soundness and have a negative impact on end‐use quality. The objective of the current study was to validate two new monoclonal peptide antibodies for wheat alpha‐amylases and describe alpha‐amylase expression in ...

The Effect of Water Management and Cell Compression in Bipolar Membrane CO2 Electrolysis to CO

open access: yesCarbon Energy, EarlyView.
In‐operando neutron imaging uncovers water management challenges in bipolar membrane CO2 electrolysis: Internal water generation floods the cathode, while compression dictates membrane and gas diffusion electrode integrity. Strategic adjustments are applied in this work: dry gas feed and mechanical support of the gas diffusion electrode enable stable ...

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology

open access: yesDeep Underground Science and Engineering, EarlyView.
This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

A Simple Approach to Select the Optimum Design Frequency for Pyramidal Horn Antenna Design

open access: yesThe Journal of Engineering
In this paper, a simple procedure is proposed to select the optimum design frequency for the horn antenna design by combining theory and simulation. The gain of horn antennas often increases and the aperture efficiency decreases while the frequency of ...

Gain improvement of a conventional conical using the perforated circular aluminum structure with a mounting PCB barrier for radar system

open access: yesResults in Engineering
This research presents a technique to enhance the gain of a conical horn antenna by introducing a squared mounting barrier made of a printed circuit board combined with a perforated aluminum dielectric, placed between the conical horn antenna and the PCB.
