Impact of Chitosan Incorporation on PBAT Composite: Thermal, Viscoelastic, Mechanical, and Morphological Properties

Journal of Applied Polymer Science, EarlyView.
The abstract explains the impact of various concentrations of chitosan on PBAT composite. Indeed, the composite is produced at increasing concentrations of chitosan (10%, 20%, and 30%). The decrease in the tensile strength with increased conc. of chitosan was recorded. Furthermore, the same impact was recorded for TGA analysis.

Design and Control of the MINDWALKER Exoskeleton

IEEE Transactions on Neural Systems and Rehabilitation Engineering, 2015
Powered exoskeletons can empower paraplegics to stand and walk. Actively controlled hip ab/adduction (HAA) is needed for weight shift and for lateral foot placement to support dynamic balance control and to counteract disturbances in the frontal plane. Here, we describe the design, control, and preliminary evaluation of a novel exoskeleton, MINDWALKER.

The cranial, mandibular, and hyoid anatomy of softshell turtles (Trionychidae): A revised character list for phylogenetic analysis

The Anatomical Record, EarlyView.
Abstract Softshell turtles (Pan‐Trionychidae) are an early branching clade of hidden‐necked turtles (Cryptodira) with a rich fossil record extending back to the Early Cretaceous. The evolutionary history of softshell turtles is still unresolved because of their conservative morphology combined with high levels of polymorphism related to morphological ...

Building phenotypic character matrices for phylogenetic inference: exploration of 35 years of practice

Biological Reviews, EarlyView.
ABSTRACT Recent methodological development in phylogenetic inference has focused predominantly on molecular data. However, renewed interest in other data types, particularly morphological data, has followed from the increased recognition of the power of total evidence and tip‐dating approaches, including fossil data, for inference of time‐scaled trees ...

Partners or passengers? Revisiting the association between diatoms and aquatic animals

Biological Reviews, EarlyView.
ABSTRACT Numerous studies have revealed the importance of research on the communities capable of colonizing animal surfaces (epibionts) and the animals on which they live (basibionts). Very few studies have considered epizoic diatoms, and there are gaps and biases in our knowledge, including the choice of basibionts, the methods used, and the habitats ...

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

Biological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Bio‐Inspired Sclerotization of Lignin: A Robust Adhesive for Photothermal Wood‐Based Panels

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A high‐performance lignin adhesive is engineered via an insect‐inspired sclerotization strategy involving oxidation and hyperbranched polymer grafting, overcoming lignin's adhesion failure, and yielding a wet shear strength of 1.02–1.21 MPa. The adhesive endows wood‐based panels with photothermal functionality; building energy simulations indicate HVAC‐

Multi-connection load compensation and load information calculation for an upper-limb exoskeleton based on a six-axis force/torque sensor

International Journal of Advanced Robotic Systems, 2019
In this article, a method of multi-connection load compensation and load information calculation for an upper-limb exoskeleton is proposed based on a six-axis force/torque sensor installed between the exoskeleton and the end effector.

Seismic Response of Existing Masonry‐Infilled RC Frame Structures Retrofitted with Steel Exoskeletons

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Considering the needs for reducing carbon emissions and except for extreme cases of very degraded existing structures, research on technologies allowing continued use or upgrading of older buildings has become a priority topic. Generally, research on upgrading of reinforced concrete frame structures certainly has a prominent role, because of ...
