Tendon‐Driven Compliant Wheel‐Less Snake Robot for Undulatory Locomotion Using Conformable Ground Contacts

Advanced Intelligent Systems, EarlyView.
This study presents a tendon‐driven compliant snake robot that uses globally applied vertical bending and axial twisting along its body to enable various gaits. Body deflection from compliance and weight passively generates the ground contact patterns required for locomotion.

Maneuverable Multilegged Locomotion through Anisotropically Arranged Soft Backbones in a Single‐Actuator Modular Miniature Robot

Advanced Intelligent Systems, EarlyView.
A modular eight‐legged robot exploits anisotropically oriented soft I‐beam backbones to transmit vibration from a single unbalanced‐mass actuator, producing frequency‐dependent multimodal gaits. A pseudo‐rigid‐body model enables high‐fidelity MuJoCo simulation, while Bayesian parameter identification and reinforcement learning yield robust control ...

Research on the Detoxification of Municipal Solid Waste Incineration Fly Ash: Organic Acid Washing Pretreatment Coupled With Cement/DDTC Stabilization

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Heavy metals in municipal waste incineration fly ash are potentially harmful to the ecological environment and human health. To mitigate the hazards of fly ash, this study attempts to detoxify fly ash through organic acid washing pretreatment coupled with cement/sodium diethyldithiocarbamate (DDTC) solidification.

Experimental Investigation of Microbubble Evolution in the Liquivac Multiphase Flow Pump

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This paper aims to experimentally investigate the mechanisms of microbubble characteristics evolution within an axial pump. The findings will aid in assessing the pump performance by identifying the range of bubble sizes and comparing them with the threshold size (< 300 μm). This study also provides evidence supporting the use of such pumps as

Polymer‐Crosslinking System‐Filler Interactions in Polychloroprene Adhesives: Experimental and Molecular Modeling Insights

Journal of Applied Polymer Science, EarlyView.
The use of polychloroprene is common in elastomeric adhesives. This study highlights the possible substitution of zinc oxide curing systems to a less hazardous metal complex, also evaluating the changes that higher surface area fillers can bring to the adhesive.

Improving Oxygen Barrier Performance of Polylactide Film by Using Bleached and Unbleached Nanocellulose From Grape Pomace

Journal of Applied Polymer Science, EarlyView.
Bleached and unbleached nanocelluloses were produced from the exhausted grape pomace and applied as coatings on PLA substrates for sustainable food packaging. Unbleached nanocelluloses were more hydrophobic and amorphous than bleached ones. The resulting bio‐based bleached nanocellulose‐coated PLA films showed a 68% reduction in O2 permeability ...

Analysis of Single Particles of Amyloid Beta and α‐Synuclein With Seeded Amplification for the Diagnosis of Alzheimer's and Parkinson's Disease

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Neurodegenerative diseases, including Alzheimer's disease (AD) and Parkinson's disease (PD), are characterized by the pathological aggregation of specific proteins such as amyloid beta (Aβ) and α‐synuclein, respectively. Early detection of these protein aggregates in biological fluids could facilitate timely diagnosis and therapeutic ...

Effective pretreatment of wet microalgal biomass to enhance lipid extraction in biodiesel production

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biodiesel is a viable alternative to fossil fuels. Identifying and evaluating nonedible sources is essential to address ecological concerns and meet energy demands. Microalgae are effective for lipid production but their rigid cell walls hinder bioproduct release making the process energy‐intensive and costly.

Hydrogel Embedding of Mesenchymal Stem Cells Supports Extracellular Vesicle Production

Biotechnology and Bioengineering, EarlyView.
This study investigates the effects of 3D culture conditions on extracellular vesicle (EV) production by mesenchymal stem cells (MSCs) in a gelatin‐based hydrogel matrix (GelMA). The EVs from both conditions were found to have similar morphological, molecular, and functional properties, but 3D cultures produced more total EVs per volume.

Preliminary Wind Turbine Rotor Design: Semi-Analytical aero-elastic wind turbine rotor design optimization

, 2020
The main purpose of a wind turbine is to create electrical energy for the electrical grid. When extracting energy from the wind, loads are exerted on the turbine blades, which carry through to the drive-train, nacelle, tower, foundation, and at last to the ground.
