On mesh refinement procedures for polygonal virtual elements [PDF]
arXiv, 2022 This work concerns adaptive refinement procedures for meshes of polygonal virtual elements. Specifically, refinement procedures previously proposed by the authors for structured meshes are generalized for the challenging case of arbitrary element geometries arising in unstructured/Voronoi discretizations.

Ti3C2Tx MXene‐Zirconium Diboride Based Ultra‐High Temperature Ceramics
Advanced Science, EarlyView.This study demonstrates the effectiveness of Ti3C2Tx MXenes as additives in ultra‐high‐temperature ceramics (ZrB₂), enhancing densification, reducing oxygen content, and improving mechanical properties. Through surfactant‐free electrostatic self‐assembly and spark plasma sintering, MXenes enabled the formation of a core–shell microstructure, resulting ...

Developing Guidelines for Two-Dimensional Model Review and Acceptance [PDF]
, 2018 Two independent modelers ran two hydraulic models, SRH-2D and HEC-RAS 2D. The models were applied to the Lakina River (MP 44 McCarthy Road) and to Quartz Creek (MP 0.7 Quartz Creek Road), which approximately represent straight and bend flow conditions ...

Multifunctional Infrared Polarizer Based on Aligned Growth of High‐Density Boron Nitride Nanotubes
Advanced Science, EarlyView.This paper presents a novel method for the high‐density, aligned growth synthesis and purification of boron nitride nanotubes (BNNTs). The polarization sensitivity and linear dichroism characteristics of BNNTs in the near‐infrared and mid‐infrared bands are comprehensively verified.

Accuracy assessment of mine walls’ surface models derived from terrestrial laser scanning
International Journal of Coal Science & Technology, 2018 The monitoring of highwall slopes at open-pit mines is an important task to ensure safe mining. For this reason, several techniques such as total station, radar, terrestrial Light Detection and Ranging (LIDAR) can be employed for surface measurement. The
