Characterization of Aluminized Layers on Inconel‐738 Alloy: Microstructure, Modeling of Aluminizing Kinetics, and Thermal Behavior

Advanced Engineering Materials, EarlyView.
This study explored how effective nickel aluminide coatings are obtained in providing oxidation resistance applied to the Inconel 738 alloy, modeling with diffusion models. In the present study, kinetics and thermal behavior of the Inconel 738 alloy were studied by the low‐temperature thermoreactive aluminizing process, which was carried out at 625°C ...

A Compact Spin‐Coated Graphene UWB Antenna for Breast Tumor Detection

Advanced Engineering Materials, EarlyView.
A compact, spin‐coated graphene ultra‐wideband patch antenna designed for breast tumor detection, capable of distinguishing between malignant and benign tumors. This innovative antenna can serve as an effective initial screening tool, particularly in resource‐limited settings such as rural areas, where access to advanced medical equipment like MRI and ...

A use-wear analysis of wood technology of patagonian hunter–gatherers. The case of Cerro Casa de Piedra 7, Argentina

, 2015
In the Patagonian archaeological record, the preservation of wooden artefacts is very restricted. Functional analysis of lithic artefacts is a way to get a better understanding about the use and consumption of the wood.

The wear behaviour of ion implanted biomaterials [PDF]

, 2003
The tribological performance of biomaterials used for artificial joints is of much importance, and require low coefficients of friction, resistance to wear and the ability to withstand many millions of cycles under a multitude of loading regimes ...

Prediction of Surface Topography Parameters in Direct Laser Interference Patterning of Stainless Steel Using Infrared Monitoring and Convolutional Neural Networks

Advanced Engineering Materials, EarlyView.
This study presents an infrared monitoring approach for direct laser interference patterning (DLIP) combined with a convolutional neural network (CNN). Thermal emission data captured during structuring are used to predict surface topography parameters.

Variable Stiffness Flexure Structures Enabled by Phase‐Change Gallium and Adhesive Interfacial Locking for Soft Robotic Applications

Advanced Engineering Materials, EarlyView.
A flexure‐based variable stiffness structure is developed by integrating phase‐change modulation and adhesive interfacial locking of gallium. The design enables a wide stiffness variability, transitioning from soft, flexible behavior to rigid, load‐supporting performance.

Scales of Analysis: the Usage of Appropriate Magnification in Use-Wear Studies

Arheologia, 2022
The interpretative potential of microscopic use-wear polishes is a factor of the scale of analysis. Observational surface area decreases in inverse proportion to magnification. In this paper I present the results of polishes on bone tools that have developed from fricative contact with nine different materials.
