Article Synopsis
- Measuring 3D chemical distribution in nanoscale materials has been challenging due to the rarity of inelastic scattering events, which require high beam exposure that can damage samples.
- High-resolution 3D chemical imaging was successfully achieved at nearly one-nanometer resolution in various nanomaterials using a method called fused multi-modal electron tomography.
- This technique significantly reduces radiation exposure by up to 99% by combining data from elastic and inelastic signals, allowing for accurate chemical mapping in complex materials.
Carbon-supported mono- and bimetallic catalysts prepared via incipient wetness impregnation were systematically studied in aqueous-phase reforming (APR) of xylitol aiming at hydrogen production from biomass. The catalytic performance of several VIII group metals and their combinations, such as Pt, Ni, Pt-Ni, Re, Pt-Re, Ru, Pt-Ru, and Pt-Co, was compared for xylitol APR in a fixed-bed reactor at 225 °C and 29.7 bar (N).

In particular, iron-based catalysts at elevated temperatures favor the selective production of C-C olefins, which are important building blocks for the chemical industry. Bulk iron catalysts (with promoters) were conventionally used, but these deactivate due to either phase transformation or carbon deposition resulting in disintegration of the catalyst particles.

The mission program was largely a continuation of the earlier flown 11 BION projects, FOTON-M2 and FOTON-M3. The biosatellite was inhabited by a great variety of living organisms used for experiments and studies in gravitational physiology, gravitational biology, biotechnology, astrobiology and radiation biology, dosimetry and spectrometry.
View Article and Find Full Text PDFAqueous phase reforming of sorbitol over Pt supported on an alumina catalyst is investigated, in order to identify the intermediates involved in the transformation of the initial feed. Parameters such as the sorbitol feed rate and temperature are studied. To identify the intermediates, an approach based on analysis of the gas and liquid phases as well as the total carbon content was developed.
