Rapid industrialization is accompanied by the deterioration of the natural environment.The deepening crisis associated with the ecological environment has garnered widespread attention toward strengthening environmental monitoring and protection.environmental sensors are one of the key technologies for environmental monitoring,ultimately enabling environmental protection.In recent decades,micro/nanomaterials have been widely studied and applied in environmental sensing owing to their unique dimensional properties.Electrospinning has been developed and adopted as a facile,quick,and effective technology to produce continuous micro-and nanofiber materials.The technology has advanced rapidly and become one of the hotspots in the field of nanomaterials research.environmental sensors made from electrospun nanofibers possess many advantages,such as having a porous structure and high specific surface area,which effectively improve their performance in environmental sensing.Furthermore,by introducing functional nanomaterials(carbon nanotubes,metal oxides,conjugated polymers,etc.)into electrospun fibers,synergistic effects between different materials can be utilized to improve the catalytic activity and sensitivity of the sensors.In this review,we aimed to outline the progress of research over the past decade on electrospinning nanofibers with different morphologies and functional characteristics in environmental sensors.

(Super)paramagnetic nanoparticles as platform materials for environmental applications: From synthesis to demonstration

引用

Frontiers of environmental Science & Engineering 2020年第5期14卷 15-23页

作者： Wenlu Li John D.Fortner Department of Chemical and environmental Engineering Yale UniversityNew HavenCT 06520USA

Over the past few decades,engineered,(super)paramagnetic nanoparticles have drawn extensive research attention for a broad range of applications based on their tunable size and shape,surface chemistries,and magnetic properties.This review summaries our recent work on the synthesis,surface modification,and environmental application of(super)paramagnetic nanoparticles.By utilizing high-temperature thermo-decomposition methods,first,we have broadly demonstrated the synthesis of highly monodispersed,(super)paramagnetic nanoparticles,via the pyrolysis of metal carboxylate salts in an organic phase.Highly uniform magnetic nanoparticles with various size,composition,and shape can be precisely tuned by controlled reaction parameters,such as the initial precursors,heating rate,final reaction temperature,reaction time,and the additives.These materials can be further rendered water stable via functionalization with surface mono/bi-layer coating structure using a series of tunable ionic/non-ionic surfactants.Finally,we have demonstrated platform potential of these materials for heavy metal ions sensing,sorption,and separation from the aqueous phase.

Antenna design for a massive multiple input environmental sensor network

引用

Digital Communications and Networks 2016年第4期2卷 256-259页

作者： J. Craig Prather Michael Bolt Haley Harrell John Manobianco Mark L. Adams Department of Electrical and Computer Engineering 200 Broun Hall Auburn University AL 36849 United States

This article describes the design and simulation of a pair of antennas on a small PCB with minimal coupling for a massive multiple input sensor network. The two antennas are planar inverted-F antennas (PIFA) that are fed with microstrip feed lines. The critical design factors are minimizing mass while creating ISM band and GPS L1 band antennas and developing data transmission schemes for maximum usage of all communication channels. The designed board is a 60 mm diameter, 0.6 mm thick circular FR4 board that weighs approximately 5 g.

＜正＞This paper deals with a Center Pattern Generator（CPG） centered sensory feedback control method for robotic fish locomotion,which improves the maneuverability and adaptability of robotic fish in water.A two-phase CPG-based control architecture to implement the autonomous locomotion in robotic fish has been proposed.The whole process of the control architecture is divided into two phases:the upper decision-making and the automatic adjustment.According to the upper command from the controller and the sensory input,a proposed finite state machine algorithm determines locomotion gaits such as straight forward/backward,turning left/right,floating up/swimming down,and so on,and modify the coupling forms and controlling parameters.And then,the CPG model with sensory feedback takes charge the autonomous locomotion control.This sensory feedback control method can improve the adaptation of the system to environmental changes,external requirements, or proprioceptive information.Corresponding experimental results validate the CPG-based sensory feedback control method, which can be extended to other robotic applications.
