Magnetoelectric (ME) composites that simultaneously exhibit ferroelectricity and ferromagnetism have recently gained significant attention as evident by the increasing number of publications. These research activities are direct results of the fact that multiferroic magnetoelectrics offer significant technological promise for multiple devices. Appropriate choice of phases with co-firing capabil...
1. The fate of an immature herbivorous insect depends on its mother’s ability to locate a host that fosters optimal growth. However, immature performance and survival is often decoupled from female host preference. 2. We used defence manipulation and exclusion experiments to investigate how oviposition choices impact survival in the diet-specialised leaf beetle, Acromis sparsa , whose larvae ar...
An evaluation of the performance a recently developed formulation (lead-free) Sodium-Bismuth titanate – Barium Titanate (NBT-BT) piezoceramic is presented through construction and testing several immersion transducers based around new material “Pz12” from CTS Ferroperm (Kvistgaard, Denmark). Results are intended to yield insight into applicability this lead-free for use within industrial, NDT, ...
PURPOSE Although the use of thyroid shields for patients for head CT examinations is reasonable and even required by German regulations, so far available shields are often not used due to difficult applicability. New shields that are easier to use and therefore may gain wider acceptance and more frequent use are now available. In this work two new patient shields are investigated regarding thei...
With the upcoming European ROHS legislation and other global movements to lead-free assembly, the NEMI lead-free rework group investigated and developed lead-free rework processes for medium to high-end computer products. The work concentrated on development of lead-free hot air convection rework for PBGA, CBGA, and uBGA, and lead-free hand soldering rework for TSOP and 2512 chip components on ...
