The development of magnetic tunnel junction fabrication techniques [PDF]

open access: yes, 2005
The discovery of large, room temperature magnetoresistance (MR) in magnetic tunnel junctions in 1995 sparked great interest in these devices. Their potential applications include hard disk read head sensors and magnetic random access memory (MRAM ...

Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

open access: yesAdvanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

Settlement prediction of undercrossing semicircular tunnel-pile set up in soft clay soil

open access: yesScientific Reports
Soil–structure interactions commonly induce displacements, with settlements in weak soils becoming increasingly significant under growing urbanization, making it important to minimize them to prevent structural defects.

Complex Modeling of the Effects of Blasting on the Stability of Surrounding Rocks and Embankment in Water-Conveyance Tunnels

open access: yesComplexity, 2018
Blasting in water-conveyance tunnels that cross rivers is vital for the safety and stability of embankments. In this work, a tunnel project that crosses the Yellow River in the north district of the first-phase Eastern Line of the South-to-North Water ...

Investigation of the unusual magnetic properties of Fe and Co on MgO with high spatial, energy and temporal resolution [PDF]

open access: yes, 2015
Nanometer-sized magnets are used as magnetic bits in data storage devices to hold information. As such devices are further miniaturized, the control of magnetism at the atomic scale becomes essential.
