Ceramic/polymer functionally graded material (FGM) lightweight armor system [PDF]

, 1998
This is the final report of a two-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). Functionally graded material is an enabling technology for lightweight body armor improvements. The objective was to demonstrate the ability to produce functionally graded ceramic-polymer and ceramic-metal ...

Extending Field Limits in Nanoscale Magnetic Imaging With Metamaterial‐Inspired Magnetic Flux Concentrators

Small, Volume 22, Issue 43, 3 August 2026.
Micrometer‐sized flower‐shaped metamaterial magnetic flux concentrators are fabricated directly around nano and micromagnetic samples, enabling local field enhancement. Integrated into magnetic sensitive photoemission electron microscopy, they extend the available magnetic field range by up to a factor of five.

A discrete model for free vibration of 3D-FGM Timoshenko beams under various boundary conditions

Discover Mechanical Engineering
Spatial variations in stiffness and mass density make the free-vibration behavior of tridirectionally functionally graded material (3D-FGM) beams highly sensitive to material gradation, while computationally efficient and accurate models for broad ...

Effect of Foam Faces and Butterfly Auxetic Core on Sandwich Nanoplate Vibration and Buckling

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 8, August 2026.
ABSTRACT This research examines the thermomechanical vibration and buckling properties of a three‐layer sandwich nanoplate, which consists of foam face layers and a butterfly‐shaped auxetic core. The formulation is developed based on Hamilton's principle and higher‐order shear deformation theory (HSDT), utilizing an analytical Navier‐type solution to ...

Integrated Molecular and Phenotypic Profiling of Circulating Tumor Cells in Gastric Cancer: A Translational Perspective

FASEB BioAdvances, Volume 8, Issue 8, August 2026.
Peripheral blood samples from gastric cancer patients were analyzed before and after curative‐intent treatment using CD45‐negative MACS enrichment. Mesenchymal CD90+ circulating tumor cells predominated over epithelial EpCAM+ cells and declined significantly following treatment.

Tailoring Surface Properties of ArF Resists with Functionally Graded Materials (FGM)

Journal of Photopolymer Science and Technology, 2007
Our recent research effort has been focused on new top coating-free 193nm immersion resists with regard to leaching of the resist components and lithographic performance. We have examined methacrylate-based resins that control the surface properties of ArF resists thin films by surface segregation behavior.
