More Materials Science on one flexible tool

Designed for multi-user and multi-discipline environments, the Talos F200i S/TEM is also ideal for novice users. It is equipped with the Thermo Scientific Velox™ user interface, which is immediately familiar since it is shared across all Thermo Scientific TEM platforms. All TEM daily tunings have been automated to provide the best and most reproducible setup. This automation eases the learning curve for novice operators, reduces tensions in a multi-user environment, and improves time-to-data for the experienced operator. A side-entry retractable Energy Dispersive X-ray Spectroscopy (EDS) detector can be added to the configuration to enable chemical analysis.

Compact design

The smaller footprint and dimensions of the Talos F200i facilitate accommodation of this tool in more challenging spaces. In addition, this compact design eases access for service needs while also reducing infrastructure and support costs.

Productivity for all users

To further enhance productivity, especially in multi-user, multi-material environments, the constant-power objective lenses, low-hysteresis design, and remote operation with SmartCam allow for straightforward reproducible mode and high-tension switches. The Talos F200i S/TEM also features educational online help. Simply pressing F1 with the mouse hovering over a control panel quickly opens relevant information.

Abstract: Silver compounds share a rich history in technical applications including photography, catalysis, photocatalysis, cloud seeding and as antimicrobial agents. Here we present a class of silver compounds (Ag2B10H10 and Ag2B12H12) that are semiconductors with a bandgap at 2.3 eV in the green visible light spectrum. The silver boranes have extremely high ion conductivity and dynamic-anion facilitated Ag+migration is suggested based on the structural model. The ion conductivity is enhanced more than two orders of magnitude at room temperature (up to 3.2 mS cm−1) by substitution with AgI to form new compounds. Furthermore, the closo-boranes show extremely fast silver nano-filament growth when excited by electrons during transmission electron microscope investigations. Ag nano-filaments can also be reabsorbed back into Ag2B12H12. These interesting properties demonstrate the multifunctionality of silver closo-boranes and open up avenues in a wide range of fields including photocatalysis, solid state ionics and nano-wire production.

Abstract: Wurtzite Zinc-gallium oxynitrides (ZnGaNO) particles were synthesized by nitridation of Zn/Ga/CO3 layered double hydroxides (LDHs) using three different coprecipitation methods, called Decreasing-pH method, Constant-pH method, and Increasing-pH Method, respectively. The obtained particles were found to be a ZnO/ZnGaNO composite, a single-phase ZnGaNO, and a porous ZnGaNO/ZnGa2O4 composite, respectively, as characterized by X-ray diffraction, scanning electron microscope, scanning and transmission electron microscope, Raman Spectroscopy, UV–vis diffuse refection spectra, and room temperature photoluminescence (PL). Photocatalytic activities of the obtained particles were evaluated under visible-light irradiation against the photodegradation of methylene blue (MB) and phenol. The ZnO/ZnGaNO heterostructure, which was formed due to sequential precipitation of Zn and Ga ions in the Decreasing-pH method, exhibited significant advance in the photocatalytic activity compared to other ZnGaNO particles. The enhanced photoactivity of ZnO/ZnGaNO particles was attributed to efficient separation of photogenerated electron-hole pairs driven by the matched band edges. The predominant active species for the phenol photodegradation over the ZnO/ZnGaNO particles were determined to be superoxide radicals and holes. The facile synthesis of the ZnO/ZnGaNO heterostructure makes it as a potential efficient visible-light responsive photocatalyst for water pollutant degradation.
Title: An efficient catalyst of manganese supported on diatomite for toluene oxidation: Manganese species, catalytic performance, and structure-activity relationship

Abstract: The work reports the preparation of diatomite-supported manganese catalysts by deposition-precipitation method, and their application for toluene oxidation. Microstructure and morphology of catalysts were investigated by Powder X-ray diffraction pattern (PXRD), thermogravimetric (TG), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and nitrogen (N2) adsorption-desorption isotherms. Temperature-programmed reduction (TPR) and temperature-programmed surface reaction (TPSR) were used to analyze the reducibility of Mn species and the reactivity of surface oxygen species, respectively. The characterization results reveal that the manganese species were mainly in the phase of amorphous MnO2 and Mn2O3 on the diatomite, and the manganese species were successfully loaded on diatomite surface and filled in pores. With the increase of Mn content, the catalytic activity enhanced, due to the increase of surface oxygen species as adsorption-reaction sites. The Mn⁴⁺ played an important role in the superior catalytic activity towards toluene. The catalyst also displays high stability and superior activity towards toluene oxidation, which presents an applied interest. The effect of Mn content on the catalytic activity of catalysts was discussed in view of reaction mechanism and variations of physicochemistry properties.

Abstract: Thin film resistive switching devices based on perovskite SrTiO3 (STO) are the subject of recent studies focused on defect kinetics [1] and electrochemical switching mechanisms [2]—work which has addressed critical aspects of material performance and device design [3]. However, nano- and atomic-scale understanding of switching mechanisms, and the role of device fabrication parameters on switching behavior and device performance is an ongoing area of research [2]. Further, multi-bit architectures offer higher device density, so guidelines for design, fabrication and characterization of these devices is desired. We investigate nano- and atomic-scale aspects of single- and stacked multi-bit thin film resistive switching devices with varying electrode materials and thin film stacking schemes. From a materials perspective, we focus on oxide microstructure, potential highly defective zones, and their interfaces with the different electrodes employed.
