We study photocurrent generation in individual suspended carbon nanotube p-n junctions using spectrally resolved scanning photocurrent microscopy. Spatial maps of the photocurrent allow us to determine the length of the p-n junction intrinsic region, as well as the role of the n-type Schottky barrier. We show that reverse-bias operation eliminates complications caused by the n-type Schottky bar...

Randomly amplified polymorphic DNA (RAPD) technique was applied to assess the genetic variations and phylogenetic relationships in genetic differentiation within 4 Chromium-treatment Leersia hexandra. The fresh leaves of Leersia hexandra cultivated on the condition of chrome pollution and exogenous organic acids were used as experimental material. The genomic DNA of Leersia hexandra was extract...

Mucormycosis, an opportunistic fungal illness, has become a global health problem in the aftermath of COVID-19 pandemic. This is mostly owing to dramatic spike infection recent months India, which was exacerbated by this co-infection. Mucormycosis exceptionally high probability death and lasting damage affected area. Although early action can save lives mitigate fungus's impact, it frequently h...

Abstract After the amazing discoveries by GRAVITY collaboration in last few years on star S2 orbiting black hole Sgr A* center of Milky Way, we present a detailed investigation impact gravitational lensing reconstruction stellar orbits around this massive hole. We evaluate astrometric effects stars S2, S38 and S55 how these systematically affect derived orbital parameters. The effect is below c...

grapes are among the world most planted horticultural crops. since the last century, attempts have been made to improve the quality of grapes in the world. meanwhile, the necessity of having knowledge about the history of progenies families led to the link between genealogy and breeding. considering some previous mislabeling, in order to find out the accuracy of the controlled crosses as well a...

El café natural (CN) se destaca por sus descriptores sensoriales diferenciales en los atributos de fragancia/aroma y sabor con respecto a cafés lavados. Dentro procedimientos para su obtención, el secado constituye un factor crítico aseguramiento calidad. Con objetivo evaluar efecto del la calidad CN evaluaron cinco modalidades, consistentes inicial al sol (S), complementado mecánico (M): S45%+...

Seven two-dimensional (2-D) seismic refraction lines were used to determine the thickness and geometry of a valley train outwash deposit of the Quaternary Henry Formation near Heyworth in southern McLean County, Illinois. These refraction data were collected and processed in 2-D, then imported into a Petrel, a three-dimensional (3-D) geological modeling software package. The 3-D geologic model ...
