Analyses of the Deformability and Chemistry of Non‐Metallic Inclusions in QT Steels With Increased Recycling‐Induced Tramp Element Content

open access: yessteel research international, EarlyView.
This work uses high‐temperature dilatometry to examine how the tramp elements Cu, Ni, and Sn affect the deformability of non‐metallic inclusions and matrix in quench‐and‐temper steel. Mg‐bearing inclusions deform less than Mg‐free ones. Copper lowers formability. Nickel increases deformability.

A low‐cost, portable polarizing digital light microscope for monitoring crystal growth and for crystal harvesting

open access: yesJournal of Applied Crystallography, EarlyView.
A low‐cost, portable, medium‐resolution polarizing digital light microscope device for monitoring crystal growth and for crystal harvesting is described. The device can be used with a cell phone or a personal computer for real‐time imaging by professional and amateur scientists alike.Motivated by the need for a convenient way to demonstrate the growth ...

Design of an 8‐Channel Transmit 32‐Channel Receive 11.7T Head Coil and Evaluation of SNR Gains

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 4, Page 2004-2018, October 2026.
ABSTRACT Purpose To design and develop an 8‐channel transmit 32‐channel receive 11.7T head coil for the strongest human MRI scanner to date, demonstrate safety, and evaluate signal‐to‐noise ratio (SNR) gains compared to 7T, the most used ultra‐high‐field (UHF) platform.

Decoupling Electron and Phonon Transport in 3D‐Printed Bismuth Telluride via Synergistic Compositional Co‐Enrichment

open access: yesAdvanced Functional Materials, Volume 36, Issue 74, 14 September 2026.
In this work, we use direct ink writing (DIW) to 3D print Bi2Te3‐based materials and naturally induce hierarchical functional nanostructures, which reduced the lattice thermal conductivity by half, resulting in high zT of 0.87and 0.89 in p‐type and n‐type compounds, respectively, competitive with commercial materials.

Low‐Temperature Gold Deposition Improves CdTe Back Contacts

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 17, 8 September 2026.
Cd(Se,Te) samples are cooled during the evaporation of Au back contacts to thermally quench CdTe degradation. Reduced temperature during Au evaporation boosts PV efficiency, open‐circuit voltage, and fill factor. XPS associates these improvements with less chemical perturbation of the CdTe surface during metallization.

Micro-scale modeling of water diffusion in adhesive composite joints

open access: yes
Water diffusion into composite adhesive joints was experimentally studied by means of gravimetric measurements in bond specimens. The main parameters controlling the diffusion in the bond components were obtained from water uptake experiments carried out

Cube-based diffusion algorithm [PDF]

open access: yes, 2007
We study molecular diffusion in (linear) nanopores with different types of roughness in the so-called Knudsen regime. Knudsen diffusion represents the limiting case of molecular diffusion in pores, where mutual encounters of the molecules within the free

Chemically Welded, Capillary‐Printed Ion‐Selective Membranes for Durable Solid‐State Chloride Sensors in Dynamic Marine Environments

open access: yesAdvanced Sensor Research, Volume 5, Issue 9, September 2026.
Chemically welded capillary printing creates durable chloride‐selective membranes that resist drift and delamination. The integrated solid‐state sensor reliably tracks tidal salinity variations, enabling scalable, low‐cost marine monitoring across distributed networks. ABSTRACT Salinity is a critical environmental parameter governing ocean circulation,
