Synergistic Effect of Two Type Cellulase Immobilized on Chitosan Microparticle as Biocatalyst for Coconut Husk Hydrolysis

Indonesian Journal of Chemistry, 2019
The effectivity of employing two types of cellulases from Aspergillus niger and Trichoderma resei covalently immobilized on chitosan microparticle was investigated. Reducing sugar from CMC yielded by immobilized cellulase from T. resei alone and A. niger

Microwall‐Integrated Terahertz Metasurfaces for Spatially Guided Label‐Free Sensing of Micrometer‐Scale Plastic Particles

Advanced Materials Technologies, EarlyView.
A THz metasurface device integrating a metal–dielectric–metal resonator with microwall‐defined recessed regions enables spatially guided, label‐free sensing of micrometer‐scale plastic particles. The as‐fabricated devices exhibit distinct THz reflection resonances for 3.1‐µm polystyrene particles and a concentration‐dependent resonance‐frequency‐shift ...

A Human Bone Defect‐on‐a‐Chip Model for Studying Bone Regeneration

Advanced Materials Technologies, EarlyView.
This study presents a novel human bone defect‐on‐a‐chip (BDOC) model, aiming to recapitulate key processes during early bone healing, incorporating bone graft substitutes. Over 21 days, human mesenchymal stem/stromal cells (HMSCs) and human primary macrophages are co‐cultured in the BDOC together with calcium phosphate microparticles.

Degradable Magnetic Composites from Recycled NdFeB Magnets for Soft Actuation and Sensing

Advanced Robotics Research, EarlyView.
This work presents a degradable soft magnetic composite made from recycled NdFeB particles embedded in a gelatin‐based organogel. The material is processed into magnetic sensors and soft robotic components, which can later be dissolved in a green solvent to recover NdFeB magnetic particles.

A Self‐Healing Permanent Magnet Putty for Soft Robot Skins With Force Sensing and Functional Recovery

Advanced Robotics Research, EarlyView.
Permanent magnet putty (PMP) integrates high‐coercivity NdFeB particles with a dynamic polyborosiloxane–Ecoflex matrix, achieving rapid self‐healing (90% mechanical recovery in 10 s) and magnetic recovery within 20 min. With twice the sensitivity of commercial putties, PMP enables precise 5–30 N force detection and discrimination between pressing and ...

Miniaturized Magnetic Tip Design for Endoluminal Vine Robot Navigation

Advanced Robotics Research, EarlyView.
A magnetic tip mount is designed for a miniaturized 7 mm soft‐growing vine robot to enable wireless magnetic steering and onboard imaging, while preserving a 3 mm working channel. The internal–external ring magnets design balances magnetic attachment with low eversion pressure. Experiments demonstrate ±90° steering, 34 mm bending radius, and successful
