Carbonaceous mesophases are liquid crystalline precursor materials that can be spun into high performance carbon fibers using the conventional melt spinning process. Carbon fiber property optimization requires a better understanding of the principles that control the structure development during the fiber formation processes and the rheological processing properties. This work presents the elas...

We review the geodesic motion of pseudo-classical spinning particles in curved spaces. Investigating the generalized Killing equations for spinning spaces, we express the constants of motion in terms of KillingYano tensors. The general results are applied to the case of the fourdimensional Euclidean Taub-NUT spinning space. A simple exact solution, corresponding to trajectories lying on a cone,...

We discuss holographic principle of double Wilson loop correlator in the case of spinning string in AdS/CFT correspondence. Following the general method proposed by Yoneya, et al. for bulk-boundary correspondence in the large J limit, we study the spinning string solution which comes from the boundary and goes to the boundary. We then show that the spinning string solution directly gives the do...

We present a new class of spinning black hole solutions in (2+1)-dimensional general relativity minimally coupled to a dilaton with potential ebφΛ. When b = 4, the corresponding spinning black hole is a solution of low energy (2 + 1)-dimensional string gravity. Apart from the limiting case of the BTZ black hole, these spinning black holes have no inner horizon and a curvature singularity only a...

Shape-persistent and tough cellulose hydrogels were fabricated by a stepwise solvent exchange from a homogeneous ionic liquid solution of cellulose exposure to methanol vapor. The cellulose hydrogels maintain their shapes under changing temperature, pH, and solvents. The micrometer-scale patterns on the mold were precisely transferred onto the surface of cellulose hydrogels. We also succeeded i...

This article describes the development and testing of the first automatically microfabricated probes to be used in conjunction with the magic angle coil spinning (MACS) NMR technique. NMR spectroscopy is a versatile technique for a large range of applications, but its intrinsically low sensitivity poses significant difficulties in analyzing mass- and volume-limited samples. The combination of m...

Characterized by distinctive evolutionary adaptations, spiders provide a comprehensive system for evolutionary and developmental studies of anatomical organs, including silk and venom production. Here we performed cDNA sequencing using massively parallel sequencers (454 GS-FLX Titanium) to generate ∼80,000 reads from the spinning gland of Actinopus spp. (infraorder: Mygalomorphae) and Gasteraca...

The objective of this work is to investigate, design, and synthesize molecular spinning machines that can be shaped in the form of membranes which can control fiber structures and produce nanofibers. Using this design entire spinning units and associated systems, which currently occupy two or three floors, can be made to fit in a small room. Fibers with custom designed structures and properties...
