Soft robotics are attractive to researchers and developers due their potential for biomimicry applications across a myriad of fields, including biomedicine (e.g., surgery), the film industry animatronics), ecology physical ‘animats’), human–robot interactions social robots), others. In contrast rigid counterparts, soft offer obvious actuation benefits, many degrees freedom in motion mimic living organisms. Many material systems have been proposed used robotic applications, involving...

ABSTRACT Collision cross section (CCS) values can enhance the identification and classification of molecular contaminants such as per‐ polyfluororoalkyl substances (PFAS). However, computational burden required for large molecules, combined with increasing number potential PFAS candidates, render existing methods incapable providing sufficiently accurate results in a timely manner. Furthermore, machine learning struggle to generalize when (de)protonated structure undergoes structural changes...

The Environmental Protection Agency (EPA) of the United States recently released first-ever federal regulation on per- and polyfluoroalkyl substances (PFASs) for drinking water. While this represents an important landmark, it also brings about compliance challenges to stakeholders in water industry as well concerns general public. In work, we address some most associated with measuring low concentrations PFASs field real matrices. First, review "continuous monitoring compliance" process laid...

Abstract Dielectric elastomers (DEs) find applications in many areas, particularly the field of soft robotics. When modeling and simulating DE-based actuators sensors, a substantial portion literature assumes selected DE material to behave some perfectly hyperelastic manner, vast majority have assumed invariant permittivity. However, studies on simple planar DEs revealed instabilities hastened breakdowns when variable permittivity is allowed. This partly due intertwined electromechanical...

We celebrate the first quantitative evidence for stress concentration effect of flaws analyzed by Inglis. Stress factor (SCF) studies have evolved ever since Inglis' 1913 result related to problem elliptical hole in a plate, which also approximately applies half-elliptical notch case. summarize hundred years development SCF with exclusive focus on analytical solutions, very specific route: series works reviewed and presented herein include parade solutions beginning (and those that followed)...

Abstract Dielectric elastomers (DEs) exhibit remarkable properties that make them stand out among other electroactive polymers. Various types of actuators based on DEs have been used in applications include artificial muscles, Braille displays, and robotic joints. In particular, conical dielectric elastomer (CDEAs) are very attractive due to their multiple degrees freedom (DOF) easiness construction. this study, an energy method is derive improved mathematical model for a double-cone...

Static mixers (SM) have become standard equipment in the process industries. They are widely used applications that involve chemical reactions, heat transfer, blending of fluids, or a combination these. Compared to mechanically agitated vessels, SMs consume less energy, require maintenance, and can provide mixing with shorter residence time. Assessment performance SM provides means categorize rank available devices new designs, which turn facilitates selection for specific applications....

Abstract As the development of soft actuators progresses, new methods for more agile actuator control are required. While there hardware technologies that can provide such agility (e.g. field-programmable-gate-array electronics), mathematical models tend to slow controlling processes. For case double conical dielectric elastomer (DCDEAs), complex material and physical often utilized; however, require extended computational time which limits real-time prediction, especially in small, portable...

Due to the aging of structures, issues plant life management and license extension are receiving increasing emphasis in many countries. Understanding failure structures due random roughness on surfaces at early stages degradation is therefore crucial. It has been shown that even slightly sinusoidal can increase stress concentration by a factor two or three, which be critical for brittle component significant reduction its load-carrying capacity, with slight roughness. A more in-depth...

Summary Understanding of surface evolution is important in applications that require engineering prescribed structures. Novel crystalized formations have been observed on titanium specimens etched with sulfuric acid as part an ongoing implantology research. Crystal resembling rosettes were discovered via scanning electron microcopy near the edges several commercially pure by immersion 18M (98%) at 60° C for 30 minutes to 1 hour. These crystallized composed numerous thin sheets (in...
