Control of the morphology ceria nanocrystals is achieved through a simple, rapid, and green chemistry approach by tuning reaction organic ligand molecules with specific crystallographic planes fluorite cubic crystal during supercritical hydrothermal synthesis, as shown in figure. It provides novel self-assembly for producing metal oxide uniform size well-defined shape.

Herein we demonstrate the extra-low-temperature oxygen storage capacity (OSC) of cerium oxide nanocrystals with cubic (100) facets. A considerable OSC occurs at 150 °C without active species loading. This temperature is 250 lower than that irregularly shaped oxide. result indicates facets have characteristics to be a superior low-temperature catalyst.
Colloidal cerium oxide (CeO2) nanocrystals prepared by hydrothermal synthesis were characterized high-resolution transmission electron microscopy (HRTEM) and three-dimensional tomography (3D-ET). HRTEM images of individual CeO2 then simulated Blochwave multislice simulations to determine the atomic arrangement terminating atoms. The edge length distributions between 5.0 8.0 nm with an average 6.7 nm. showed that particles slightly truncated revealing {220} facets. 3D-ET revealed exposed...
A peptide with an affinity for ZnO, selected by a phage-display system, preferentially immobilizes ZnO particles on gold-coated polypropylene plate and assists in the homogeneous assembly of 10 nm diameter nanoparticles into unique flower-like morphologies (see Figure). The is selective binding but not ZnS or Eu2O3. This combinatorial library approach may yield new peptides used to create structures via biomineralization.
Biological applications of nanoparticles are rapidly increasing, which introduces new possibilities to improve the efficacy radiotherapy. Here, we synthesized titanium peroxide (TiOxNPs) and investigated their as novel agents that can potently enhance effects radiation in treatment pancreatic cancer. TiOxNPs polyacrylic acid-modified (PAA-TiOxNPs) were from anatase-type dioxide (TiO2NPs). The size morphology PAA-TiOxNPs was evaluated using transmission electron microscopy dynamic light...
Abstract Since the early 1990s, Adschiri and his colleagues have performed research on use of supercritical water in diverse applications, including heavy oil reforming, waste polymer decomposition chemical raw materials recovery, cellulose hydrolysis sugar lignin nanoparticle synthesis. Regarding inorganic synthesis, they invented hydrothermal synthesis for continuous flow metal oxide nanoparticles, which has already found worldwide industrial applications. They proposed a two-fluid mixing...
ABSTRACT Supercritical water liquefaction and gasification is reviewed with the introduction of some recent findings by authors. suitable for recovery energy from wet biomass while supercritical opens door to effective treatment species in terms material recovery. Cellulose, one main components biomass, completely dissolved water. Once dissolved, reaction cellulose can take place swiftly hydrolysis pyrolysis. The reaction, otherwise slower than pyrolysis due mass transfer limitation, faster...
The electrode performance of a single solid‐fuel cell (SOFC) was evaluated using 500 μm thick (LSGM) as the electrolyte membrane. A doped lanthanum cobaltite, selected cathode material, and samaria‐doped ceria‐NiO composite powder used anode material. spray‐pyrolysis method applied for synthesis starting powders anode. In this study, different microstructures were obtained by varying sintering temperature from 950 to 1200°C. High power density (the maximum about , which is 95% theoretical...
The growth of metal oxide nanocrystals with a well-organized crystalline phase is fundamental and technological interest because in this way it possible to tune their size-dependent unique properties. In communication, we demonstrate the selective monoclinic tetragonal ZrO2 <10 nm diameter driven by controlling surface energy, without capping N(CH3)4+. were grown aqueous solution at 150 °C. It was revealed, transmission electron microscopy, X-ray diffraction, Raman spectroscopy, optical...
We report magnetism of spinel ${\text{Co}}_{3}{\text{O}}_{4}$ nanocrystals with average diameters $\ensuremath{\sim}25$ and $\ensuremath{\sim}100\text{ }\text{nm}$ under magnetic fields up to 50 kOe. The nanoparticles were controlled be cubic in shape. In the smaller nanocrystal sample $(d\ensuremath{\sim}25\text{ }\text{nm})$, a spontaneous moment increased steeply below N\'eel point, ${T}_{N}=32\text{ }\text{K}$ bulk sample, whereas similar samples larger crystal...
We compare the Raman scattering properties of hybrid nanostructures consisting Ag nanoparticles (NPs) in disordered and aligned arrangements on single-walled carbon nanotubes (SWCNTs) as a result chemical photoreduction methods. In latter case, unique structure very small NP (from 4 to 7 nm) chains generated an extremely large mode at 969 cm−1 that was assigned sulphate-silver interaction surface. Another strong present 1201 IR-active sodium dodecyl sulphate (SDS); this observed because...
Removing volatile organic compounds (VOCs) from the environment via photocatalytic reactions is highly effective for achieving clean air. While Pt deposition on TiO₂ surfaces recognized as a viable catalytic method, understanding interaction, dispersion, and facet optimization remain incomplete, leading to suboptimal performance cost inefficiencies. This study investigates adsorption rutile TiO2 surfaces, focusing (101) (110) facets. It reveals that attachment strongly influenced by surface...
