The urgent stipulation is to manufacture CNTs of desired properties and dimensions. The heart of this yearning lies in understanding the growth and assembly methods of CNTs, which are not yet clear. In this study, hence, we concentrate on the synthesis and assemblage, pointing out the parameters, issues, and limitations of the available techniques. While(More)
The construction of miniaturized rotating electric machines through microfabrication techniques is becoming a reality. Applications of such micromotors include miniaturized pumps, compressors, fans, coolers, and turbogenerators. However, the characteristics of these devices make the design of power electronics for them challenging. These characteristics(More)
This work presents the size-selective sorting of single biological cells using the assembly process known as templated assembly by selective removal (TASR). We have demonstrated experimentally, for the first time, the selective placement and sorting of single SF9 cells (clonal isolate derived from Spodoptera frugiperda (Fall Armyworm) IPLB-Sf21-AE cells)(More)
A modeling study of the potential for storing energy in the elastic deformation of springs comprised of carbon nanotubes (CNTs) is presented. Analytic models were generated to estimate the ideal achievable energy density in CNTs subject to axial tension, compression, bending and torsion, taking into account limiting mechanisms such as the strength of(More)
The design, creation, and demonstration of a singlet oxygen generator (SOG) that operates on the microscale are presented. The micro singlet oxygen generator (μSOG) chip creates singlet delta oxygen (O2(Δ)) in an array of packed bed reaction channels fed by inlets with pressure drop channels to equalize flow. An integrated capillary array separates the(More)
The use of templated assembly by selective removal to simultaneously and selectively assemble silica microspheres of two different diameters into designated sites on a surface was demonstrated. Microspheres with diameters of 636 nm and 2 µm were assembled from fluid onto templates patterned to contain holes that matched the shapes and sizes of the spherical(More)
Precise, size-selective assembly and sorting are demonstrated in a low-cost system using manufacturable, replicated polymer templates to guide the assembly. Surface interactions between microscale objects and an assembly template are combined with fluid forces to drive site-selective organization of objects onto the template. Although controlling the(More)
A site-selective self-assembly technique called templated assembly by selective removal is introduced. Initial experiments demonstrated selective assembly of 1.58 mum microspheres into shape-matched holes in a lithographically defined template. Very high frequency ultrasound selectively removes components from poorly matched holes. The successful(More)
This work presents a study of the tensile mechanical properties of millimeter-long fibers comprising carbon nanotubes (CNTs). These CNT fibers are made of aligned, loosely packed parallel networks of CNTs that are grown in and harvested from CNT forests without drawing or spinning. Unlike typical CNT yarn, the present fibers contain a large fraction of CNTs(More)
