In Situ TEM Observation of MgO Nanorod Growth [PDF]

Crystal Growth & Design, 2009
The controlled growth of MgO nanorods was investigated under electron irradiation in transmission electron microscopes at accelerating voltages from 120 to 300 kV in the temperature range from −175 to 610 °C. The nanorod growth on the surface of MgO crystals was induced by Au, Pt, Ni, or Co particles of 2−4 nm in size.

Attraction of semiconductor nanowires: An in situ observation

Acta Materialia, 2013
In situ deformation transmission electron microscopy was used to study the attraction behavior of GaAs semiconductor nanowires (NWs). The NWs demonstrated an interesting phenomenon of either head-to-head or body-to-body attraction at distances that depend on the NW diameters.

In Situ Observation on the Effects of Prior Martensite Formation on Nanostructured Low–Temperature Bainite Transformation

Metals, 2018
Nanobainite transformation behavior was comparably studied using in situ observations for two heat treatments: With and without partial quenching before isothermal holding at 300 °C.

Electrochemical behavior and in situ observation of galvanic couples of copper and silver or zinc wires in acidic copper sulfate solutions

Journal of MMIJ, 2023
The anodic dissolution reaction of copper in copper electro-refining was studied by considering the reaction of galvanic couples with different metals as impurities.

Injection of High Chlorophyll-a Waters by a Branch of Kuroshio Current into the Nutrient-Poor North Pacific Subtropical Gyre

Remote Sensing, 2022
An unusual eastward flow was observed branching out from the Kuroshio Current near the island of Taiwan in the western North Pacific in during the period June–July 2010. The branch meandered eastward approximately 21°N, carrying high chlorophyll-a (Chla)

Early identification on failure mode of loess landslide: insight from case study and physical model experiment

Frontiers in Earth Science
IntroductionThe Loess Plateau has long been plagued by cascading loess landslides. The rapid identification of these landslides, along with the accurate determination of their failure modes, is essential for conducting precise disaster assessments in the

Detection of a weak meddy-like anomaly from high-resolution satellite SST maps

Scientia Marina, 2012
Despite the considerable impact of meddies on climate through the long-distance transport of properties, a consistent observation of meddy generation and propagation in the ocean is rather elusive.
