Microstructure of nanocrystalline diamond powders studied by powder diffractometry [PDF]

, 2005
High resolution x-ray diffraction peaks of diamond nanosize powders of nominal sizes ranging from 5 to 250 nm were analyzed and provided information on grain structure, average size of crystallites, and concentration of dislocations.

Avicenna on the PSR and Causal Necessity in the Natural World

Theoria, EarlyView.
ABSTRACT Avicenna's account of causal necessity in the natural world is a key part of his metaphysical system and it is also historically significant. Yet, there is little scholarly discussion of the philosophical basis of his view. This is surprising not only because the topic is important, but also because the view is challenging to interpret ...

Thermal, rheological and morphological properties of poly (Lactic Acid) (PLA) and talc composites

Polímeros, 2014
In this study, composites based on poly(lactic acid) (PLA)/talc were prepared at different compositions by melt mixing in a twin screw extruder. The effect of a nucleating agent, talc, on the crystallization behavior, rheological and morphological ...

Creep of Talc at Subduction Zone Conditions: Implications for Slow Slip and Strength of the Lithosphere

Geophysical Research Letters
Talc can strongly influence the rheological properties of the subduction interface. Despite geologic evidence for talc at the interface, and proposed links between its rheology and slow slip events, few experiments have been conducted on talc at relevant

Material properties of nanoclay PVC composites [PDF]

, 2009
Nanocomposites of poly(vinyl chloride) have been prepared using both hectorite- and bentonite-based organically-modified clays. The organic modification used is tallow-triethanol-ammonium ion.

Valorization of fruit pits from Prunus laurocerasus and Prunus cerasifera as agro‐food byproducts: Bioactive properties and safety assessment for potential food additive applications

Journal of the Science of Food and Agriculture, Volume 106, Issue 10, Page 6002-6014, 15 August 2026.
Abstract BACKGROUND Food additives are widely used to extend the shelf life of foods and maintain their quality. In this study, the potential of Prunus laurocerasus and Prunus cerasifera fruit pits (endocarp and seed) as food additives was investigated in terms of cytotoxicity, antigenotoxicity, antioxidant activity, enzymatic anti‐browning, and urease

Prediction of Properties of Polymer Composite Formulations Using Ensemble Models With Feature Generation

Journal of Applied Polymer Science, Volume 143, Issue 25, July 5, 2026.
This study develops an interpretable machine‐learning framework to predict multiple properties of polymer composites based on composition and processing variables. By combining ensemble models with composition‐based feature generation and SHAP‐based interpretation, the approach reveals composition‐property relationships and supports efficient multi ...
