Tau fibrils are the main proteinacious components of neurofibrillary lesions in Alzheimer disease. Although RNA molecules are sequestered into these lesions, their relationship to Tau fibrils is only poorly understood. Such understanding, however, is important, as short fibrils can transfer between neurons and nonproteinacious factors including RNA could play a defining role in modulating the l...

The use of biological structures to template inorganic materials has become an increasingly widespread strategy to develop otherwise synthetically inaccessible hierarchical structures under mild chemical conditions, for use as catalytic and device materials. For example, proteins, peptides, DNA, viruses, cells and multicellular structures have been employed as templates to develop inorganic par...

This paper reports template-based growth of nanorod arrays by combination of sol–gel processing and centrifugation. The technical concept is simple and straightforward; centrifugation force drives the sol nanoclusters into the pores of the template, filling the pores completely to form nanorods. However, simulation reveals the formation of nanorods inside pores is more complex; centrifugation f...

The generic programming paradigm has exerted great influence on the recent development of C++, e.g., large parts of its standard library [2] are based on generic containers and algorithms. While templates, the language feature of C++ that supports generic programming, have become widely used and well understood in the last years, one aspect of templates has been mostly ignored: template templat...

Template-based sol electrophoretic deposition has been demonstrated as an attractive method for the synthesis of oxide nanorod arrays, including simple and complex oxides in the forms of amorphous, polycrystalline, and single crystal. This paper systematically studied a number of processing parameters to control nanorod growth by sol electrophoretic deposition. The influences of particle and te...

Single crystalline indium nanowires were prepared on Zn substrate which had been treated in concentrated sulphuric acid by galvanic displacement in the 0.002 mol L-1In2(SO4)3-0.002 mol L-1SeO2-0.02 mol L-1SDS-0.01 mol L-1citric acid aqueous solution. The typical diameter of indium nanowires is 30 nm and most of the nanowires are over 30 μm in length. XRD, HRTEM, SAED and structural simulation c...

The information problem in prebiotic evolution arises from constraints on the amount of information that can be maintained in Darwinian evolution. The error threshold limits the transmissible length of a template under high mutation load. Existing solutions to the error threshold assume that the primitive genome consisted of multiple coexisting unlinked templates. Such coexistence requires a me...

objective: to date, several scaffolds have been fabricated for application in bone tissue repair. however, there remains a need for synthesis of scaffolds with better mechanical properties, which can be applied to defects in weight-bearing bones. we constructed a composite ceramic bioscaffold of hydroxyapatite-alumina and silicon carbide (ha-al2o3- sic) to take advantage of the mechanical prope...

Self-assembling biomolecules provide attractive templates for the preparation of metallic nanostructures. However, the intuitive transfer of the "outer shape" of the assembled macromolecules to the final metallic particle depends on the intermolecular forces among the biomolecules which compete with interactions between template molecules and the metal during metallization. The shape of the bio...

Accurate robot localization relative to orchard row centerlines is essential for autonomous guidance where satellite signals are often obstructed by foliage. Existing sensor-based approaches rely on various features extracted from images and point clouds. However, any selected not available consistently, because the visual geometrical characteristics of rows change drastically when tree types, ...
