Synthesis of highly aligned single-walled carbon nanotubes (SWNTs) with controlled positions is an important step toward manufacturable ultradense carbon nanotube integrated circuits. One of the most promising synthesis methods is chemical vapor deposition (CVD), in which small catalyst particles with diameters of approximately a few nanometers determine the position and diameter of SWNTs.1 Sig...

Purpose: To compare patient outcomes after 180 W XPS Greenlight photoselective vaporization of the prostate (PVP) and Green laser enucleation of the prostate (GreenLEP) used to surgically manage benign prostatic obstruction (BPO). Materials and Methods: Two groups of 60 consecutive patients with enlarged glands (>80 mL) underwent either GreenLEP or PVP (performed by the same surgeon and includi...

The importance of adapting networks of workstations for use as parallel processing platforms is well established. However, current solutions do not always address important issues that exist in real networks. External factors like the sharing of resources, unpredictable behavior of the network, and failures, are present in multiuser networks and must be addressed. Calypso is a prototype softwar...

In this paper, we report the fabrication and photoelectric properties of CdTe/TiO2 nanocrystal multilayer. Negatively charged CdTe nanocrystal hydrosols were synthesized in the aqueous phase with 3-mercaptopropionic acid as a surface modifier. The characterization of transmission electron microscopy (TEM) and UV-visible absorption spectrum indicates the resultant CdTe nanocrystal hydrosols are ...

We here report on the fabrication of electroplated nickel (Ni) masks for dry etching of sub-micron patterns in lithium niobate (LiNbO3). This process allows obtaining a 350-nm thick Ni mask defining high air filling fraction holey arrays (e.g. openings of 1800 nm in diameter with inter-hole spacing of 300nm, or 330-nm diameter holes spaced by 440-nm). The mask profile is perfectly vertical (ang...

-It has been claimed that quantified features are inappropriate for phylogenetic analysis. We consider that claim to be true under most conditions for characters discovered by commonly used morphometric methods, including outline-based and conventional multivariate methods. The most important reason these characters are unsuitable is that one of the tests of homology, the test of similarity, ma...

Aquatic and terrestrial biodiversity are highly intertwined in tropical temperate floodplains (Horn et al., 2011; Junk, 2005; Opperman 2017). In Amazonian floodplain forests, many fish species expand their distribution, from main river channels onto inundated during the annual high-water season (e.g. Carvalho 2009; Goulding, 1980; Goulding 1988). These forests provide crucial feeding nursery gr...

The controlled manipulation of molecules is a crucial prerequisite for the emerging field of molecular nanotechnology. AC electrokinetics provide a powerful mechanism for both positioning and inducing conformational changes in molecules. In this paper, we investigate the elongation of fluorescently-labelled DNA strands, which are covalently tethered by one end to gold microelectrodes arranged i...

Protein chips technology has emerged as a promising tool for screening protein-protein interactions and characterizing the levels of proteins expressed in cells. Novel surface technologies must be improved to satisfy the specific protein orientation on the surface without denaturation, retaining non-fouling character of the surface. In order to construct facile immobilization of protein on the ...

Areas of single-layer MoS2 film can be prepared in a tube furnace without the need for temperature control. The films were characterized by means of Raman spectroscopy, photoluminescence, low-energy electron diffraction and microscopy, and X-ray photoelectron spectroscopy and mapping. Transport measurements show n-doped material with a mobility of 0.26 cm V−1 s−1. Molybdenum disulfide, MoS2, ha...
