Morphology and structure of YSZ powders: Comparison between xerogel and aerogel [PDF]

, 2009
Yttria-stabilized zirconia (YSZ) fine powders were prepared via sol–gel route in order to shape thermal barrier coatings (TBCs) from these powders. The main objective is to develop new undirectional coatings to allow best thermo-mechanical accommodations

Morphology–Coordination Coupling of Fe–TCPP and g-C₃N₄ Nanotubes for Enhanced ROS Generation and Visible-Light Photocatalysis

Nanomaterials
Fe–porphyrin/g-C3N4 composites have emerged as promising visible-light photocatalysts, but their performance remains limited by inefficient charge separation and low reactive oxygen species (ROS) yield.

The Influence of Inulin on the Retention of Polyphenolic Compounds during the Drying of Blackcurrant Juice

Molecules, 2019
In blackcurrant juice powders made using freeze-, vacuum-, and spray-drying methods, 19 polyphenolic compounds were identified: anthocyanins (6), (+)-catechin, flavonols (8), and phenolic acids (4). The highest content of identified polyphenols was noted

Crystallography with powders

Nature Materials, 2014
Over the course of its long history, powder diffraction has provided countless insights into the properties of materials. It will continue to do so in the future, but with an emphasis on elucidating how materials respond to external stimuli.

In vitro and in silico modelling of ROS1‐positive non‐small cell lung cancer reveals fusion‐dependent tyrosine kinase inhibitor responses

Molecular Oncology, EarlyView.
Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.

Determination of the Chemical Composition of Lithium Niobate Powders

Crystals, 2019
Existent methods for determining the composition of lithium niobate single crystals are mainly based on their variations due to changes in their electronic structure, which accounts for the fact that most of these methods rely on experimental techniques ...

Epigenetic silencing of the liver‐specific lncRNA LUNAR promotes liver cancer progression via NOTCH activation

Molecular Oncology, EarlyView.
LUNAR is a liver‐specific long noncoding RNA (lncRNA) that is highly expressed in normal liver but becomes epigenetically silenced in hepatocellular carcinoma through promoter hypermethylation. Loss of LUNAR is associated with NOTCH activation, epithelial–mesenchymal transition, and metastasis, whereas restoring LUNAR restrains metastatic progression ...

Influence of gas type on microstructure and characteristics of super duplex stainless steel alloy powders prepared via gas atomization

Journal of Materials Research and Technology
Conventional powder preparation methods, such as ball milling, often fail to produce fine, uniform, and spherical metal powders, limiting their suitability for advanced powder metallurgy (PM) and additive manufacturing (AM) applications.
