Surface energy and stress driven growth of extremely long and high-density ZnO nanowires using a thermal step-oxidation process.

Formation of highly crystalline zinc oxide (ZnO) nanowires with an extremely high aspect ratio (length = 60 μm, diameter = 50 nm) is routinely achieved by introducing an intermediate step-oxidation method during the thermal oxidation process of thin zinc (Zn) films. High-purity Zn was deposited onto clean glass substrates at room temperature using a vacuum-assisted thermal evaporation technique. Afterwards, the as-deposited Zn layers were thermally oxidized under a closed air ambient condition at different temperatures and durations.

Resolving the polycistronic aftermath: Essential role of topoisomerase IA in preventing R-loops in Leishmania.

Kinetoplastid parasites are "living bridges" in the evolution from prokaryotes to higher eukaryotes. The near-intronless genome of the kinetoplastid Leishmania exhibits polycistronic transcription which can facilitate R-loop formation. Therefore, to prevent such DNA-RNA hybrids, Leishmania has retained prokaryotic-like DNA Topoisomerase IA (LdTOPIA) in the course of evolution.

Nanostructural evolution of hydrothermally grown SrTiOperovskite and its implementation in gaseous phase detection of ethanol.

A group of SrTiOnanostructures with unique nano-architecture have been synthesized in the current study. Sol-gel derived TiOnanoparticles along with Sr(OH)solution was processed with facial hydrothermal reaction at 180 °C and highly stable and distinct morphologies of SrTiOwere developed after different reaction time. Nanobush, nanograss, nanorod and nanosphere morphologies were created after 10, 14, 18 and 24 h of hydrothermal reaction.

A Bumpy Ride of Mycobacterial Phagosome Maturation: Roleplay of Coronin1 Through Cofilin1 and cAMP.

Phagosome-lysosome fusion in innate immune cells like macrophages and neutrophils marshal an essential role in eliminating intracellular microorganisms. In microbe-challenged macrophages, phagosome-lysosome fusion occurs 4 to 6 h after the phagocytic uptake of the microbe. However, live pathogenic mycobacteria hinder the transfer of phagosomes to lysosomes, up to 20 h post-phagocytic uptake.

C-encapsulated TiOnanoparticles for selective and ultrahigh sensitive detection of formaldehyde.

The current study concerns development of fullerene-C-encapsulated TiOnanoparticles hybrid for an efficient detection of volatile organic compounds (VOCs). The nanocomposite was synthesized via chemical route by using hydrated fullerene-Cand sol-gel derived undoped-type TiOnanoparticles. The nanocomposite was characterized morphologically and structurally comparing with pure Cclusters and pure TiOnanoparticles as the reference materials.

Electroless deposition of Pd/Pt nanoparticles on electrochemically grown TiO nanotubes for ppb level sensing of ethanol at room temperature.

This work presents a comparative sensing study of three sensors based on pristine TiO nanotubes, Pd loaded TiO nanotubes, and Pt loaded TiO nanotubes. Pristine TiO nanotubes were synthesized using an electrochemical anodization method and an electroless plating method was used for the uniform deposition of noble metal nanoparticles of either Pd or Pt over the surface of TiO nanotubes. The samples were thoroughly characterized by XRD, FESEM, EDS, TEM, and XPS techniques.

Multiple nano-filaments based efficient resistive switching in TiO nanotubes array influenced by thermally induced self-doping and anatase to rutile phase transformation.

In this paper, the impact of thermally induced self-doping and phase transformation in TiO based resistive random-access memory (ReRAM) is discussed. Instead of a thin film, a vertically aligned one-dimensional TiO nanotube array (TNTA) was used as a switching element. Anodic oxidation method was employed to synthesize TNTA, which was thermally treated in the air at 350 °C followed by further annealing from 350 °C to 650 °C in argon.

Oxygen vacancy modulation of titania nanotubes by cathodic polarization and chemical reduction routes for efficient detection of volatile organic compounds.

In this work, we have synthesized a highly ordered TiO nanotube array by an electrochemical anodization method. Then the oxygen vacancy level of the TiO nanotubes was tuned by two different methods: i.e.

A Spatio-Temporal Model for Longitudinal Image-on-Image Regression.

Neurologists and radiologists often use magnetic resonance imaging (MRI) in the management of subjects with multiple sclerosis (MS) because it is sensitive to inflammatory and demyelinative changes in the white matter of the brain and spinal cord. Two conventional modalities used for identifying lesions are T1-weighted (T1) and T2-weighted fluid-attenuated inversion recovery (FLAIR) imaging, which are used clinically and in research studies. Magnetization transfer ratio (MTR), which is available only in research settings, is an advanced MRI modality that has been used extensively for measuring disease-related demyelination both in white matter lesions as well across normal-appearing white matter.
