Preparation and Identification of Heavy Minerals for Archaeometrical Studies: Villa of Fiumana (FC), Italy

open access: yesJournal of Raman Spectroscopy, EarlyView.
This paper presents a new protocol for the laboratory preparation of archaeological samples. Ceramics that have been hand‐crafted using different sediments as raw materials were collected in a Roman Villa sited in Fiumana (FC), Italy. This method aims at concentrating and analysing heavy minerals in the 15–250 μm grain size fraction, studying the ...

Investigation of the Mechanical Behaviors of Waterborne Polyurethane: The Critical Influence of Hard Segment Content Over Various Strain Rates

open access: yesMacromolecular Materials and Engineering, EarlyView.
This study explores how hard segment content (HS) modulates waterborne polyureathane's (WPU's) dynamic mechanical properties under low/high strain rates. Increasing HS enhances hydrogen bonding and microphase separation, with abundant hard domains acting as physical crosslinks.

Experimental Study on Polymer–Polymer Interfacial Thermal Resistance

open access: yesMacromolecular Theory and Simulations, Volume 34, Issue 2, March 2025.
Interfacial thermal resistance (ITR) in polymer–polymer interfaces is experimentally measured in this paper by the multi‐layered bulk sample approach. Based on numerical simulation and experimental verification, new techniques of layer‐overlapping samples are developed.

High throughput characterization method of electrical and phonon properties by dielectric resonant spectroscopy

open access: yesMaterials Genome Engineering Advances, EarlyView.
In conventional theories, electron‐phonon relaxation time τe‐p ${\tau }_{e\mbox{-}p}$—the average interval between two consecutive electron‐phonon collisions—is assumed to be independent of electron density. In this study, we establish a new relationship of τe−p=C∗·T−1·n−1/3 ${\tau }_{e-p}={C}^{\ast }\mathit{\cdot }{T}^{-1}\mathit{\cdot }{n}^{-1/3 ...
