Influence of Particle Shape and Size in Copper‐Based Low‐Temperature Metallization Paste for Solar Cells

open access: yesAdvanced Engineering Materials, EarlyView.
Particle morphology controls the balance between printability and electrical connectivity in low‐temperature AgCu/Ag metallization pastes. Flake‐shaped AgCu particles form extended low‐resistance contacts, whereas spherical particles favor processability at high metal loading. Fine Ag particles further tune void filling and conductive‐network formation

Microstructural, Mechanical, and Textural Evolution of Dissimilar Combination of Laser‐Welded Maraging Steel and 4340 Steel

open access: yesAdvanced Engineering Materials, EarlyView.
The present work reports the microstructural, mechanical, and texture evolution of a dissimilar combination laser‐welded maraging steel with 4340 steel. This is important for aerospace applications. The demand for dissimilar welding is growing rapidly with the requirement of efficient and durable joints.

Direct determination of angular velocity using GPS

open access: yes, 2000
Controlling a ship in a berthing operation is carried out mainly by the change of state, such as velocity and yaw rate (turn rate), although the value of the change of state is very small at berthing.

Influence of Fe Particle Size Distribution on Chemical Homogeneity, Microstructure, and Crack Formation in Fe–SiC Powder Blends Processed by PBF‐LB/M

open access: yesAdvanced Engineering Materials, EarlyView.
The influence of Fe particle size on in situ alloying of Fe–SiC powder blends in PBF‐LB/M is revealed. Contrary to expectations, the coarser Fe fraction provides a broader crack‐free processing window and slightly improved elemental homogeneity while producing higher but more variable hardness. The results highlight a complex trade‐off between particle

Analysis of the crank angular velocity with use of cinemetry methods and reed-switch sensors

open access: yesRevista Brasileira de Cineantropometria e Desempenho Humano, 2006
This study analyzed the crank angular velocity across the pedaling cycle. The purpose was to compare values obtained from kinematic analysis to data gained through reed- switch sensors, which consider the cycle to have a constant angular velocity.

Effect of Calendering and Surface Treatment on the Thermochromic Response of Cholesteric Liquid Crystals on PET Nonwovens

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the influences of calendering and surface treatment during direct ink writing (DIW) of thermochromic cholesteric liquid crystal (CLC) on PET nonwovens. For the PVA‐coated nonwovens, calendering reduces pore size leading to reduced ink absorption and enhanced spreading. The NeverWet‐coated nonwovens improve thermochromic responses by

Multi-Dimensional Motion Parameter Estimation of a Rotating Object Based on Orbital Angular Momentum

open access: yesIEEE Access
This paper considers the multi-dimensional motion patterns of a rotating object and presents methods to estimate its motion parameters, including the rotational direction, angular velocity, motion trajectory, and inclination angle, using orbital angular ...
