PASTA‐ELN: Simplifying Research Data Management for Experimental Materials Science

Advanced Engineering Materials, EarlyView.
Research data management faces ongoing hurdles as many ELNs remain complex and restrictive. PASTA‐ELN offers an open‐source, cross‐platform solution that prioritizes simplicity, offline access, and user control. Its in tuitive folder structure, modular Python add‐ons, and open formats enable seamless documentation, FAIR data practices, and easy ...

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Detemination of The Best Method (HF, MP2 and B3LYP) in Calculation of Chemical Hardness

, 2018
Chemical hardness of 62 molecules are calculated at different 18 levels. No imaginargy frequency is observed in optimization results for each level. Correlation between experimental and calculated hardness values are investigated.

High‐Temperature Nanoindentation of Metals: Assessing Thermal Drift, Frame Compliance, and Chemical Composition Effects on the Reported Mechanical Properties

Advanced Engineering Materials, EarlyView.
Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

Effect of Nd: YAG Laser on Hardness and Color Change of High Impact Acrylic Denture Base Material

Ibn Al-Haitham Journal for Pure and Applied Sciences
Polymethyl methacrylate (PMMA) is widely used for denture bases but suffers from limited fracture resistance; high impact acrylic, enhanced with butadiene styrene rubber, improves strength. Lasers, particularly the Nd: YAG type, have been used to modify

Chemical bond and hardness of M-,W-type hexagonal barium ferrites

, 2011
Using the chemical bond theory of dielectric description, the chemical bond parameters of the M-, W-type hexagonal barium ferrites were calculated. The hardness of BaFe12O19 and BaFe18O27 were calculated. The calculated hardness of BaFe12O19 is 5.9 GPa,

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Ultra-high surface hardness in nitrogen ion implanted low alloy steel

, 2002
The surface composition of low alloy steel after N2 + implantation was studied with X-ray photoelectron spectroscopy (XPS). The effect of the implantation on the mechanical hardness was evaluated by ultra-micro-hardness indentation.

Soft Mechanical‐Electrical Logic Using Liquid Metal‐Filled 3D‐Printed Architectures

Advanced Engineering Materials, EarlyView.
We present 3D‐printed soft mechanical–electrical logic elements that use liquid metal–filled silicone tubes actuated by thermoplastic polyurethane/polylactic acid (TPU/PLA) architectures to produce Boolean operations. Complementary normally open and normally closed unit cells perform repeatable binary transitions and can be combined into more complex ...

Mechanical and chemical characterization of biochar-reinforced polystyrene composites

BMC Chemistry
This study investigates the chemical interactions and mechanical characteristics of composites made of polystyrene reinforced with biochar. Polystyrene-based resin (PBR) was combined with plantain peel-derived biochar in different weight ratios (10%, 20%,
