Electronic devices such as mobile phones and tablets spur on a scientific race to find smaller and smaller information processing and storage elements. One of the challenges in this race is to reproduce certain magnetic effects at nanometre scale.
New work by researchers at UC Berkeley could soon transform the building blocks of modern electronics by making nanomagnetic switches a viable replacement for the conventional transistors found in all computers.
According to a new theory by Rice University scientists, imperfections in certain two-dimensional materials create the conditions by which nanoscale magnetic fields arise.
By the time people began to look for viable routes on the ocean with the help of a compass needle in the 12th century, magnetic navigational aids had already long been in use by other living creatures. Migratory birds orient themselves with respect to the Earth’s magnetic field, but some unicellular organisms, called magnetotactic bacteria, do as well. They carry within them a chain of nanoparticles of magnetite, a magnetic mineral that functions as an internal compass.
While searching for ever smaller devices that can be used as data storage systems and novel sensors, physicists at Johannes Gutenberg University Mainz (JGU) have directly observed magnetization dynamics processes in magnetic nanowires and thus paved the way for further research in the field of nanomagnetism.
Separating target molecules in biological samples is a critical part of diagnosing and detecting diseases. Usually the target and probe molecules are mixed and then separated in batch processes that require multiple pipetting, tube washing and extraction steps that can affect accuracy.
Carbon nanotubes are hollow, cylindrical molecules that can be manipulated to give them useful properties. The nanoparticles were discovered accidentally on the rough surfaces of a reactor designed to grow carbon nanotubes.
A team of scientists, led by University of Illinois physicist Peter Schiffer, has reported direct visualization of magnetic charge crystallization in an artificial spin ice material, a first in the study of a relatively new class of frustrated artificial magnetic materials-by-design known as “Artificial Spin Ice.” These charges are analogs to electrical charges with possible applications in magnetic memories and devices. The research team's findings appear in the August 29 issue of the journal Nature.
Researchers at Umeå University, together with researchers at Uppsala University and Stockholm University, show in a new study how nitrogen doped graphene can be rolled into perfect Archimedean nano scrolls by adhering magnetic iron oxide nanoparticles on the surface of the graphene sheets. The new material may have very good properties for application as electrodes in for example Li-ion batteries.
Micromem Technologies Inc. (the "Company") through its wholly owned subsidiary Micromem Applied Sensor Technologies Inc. (MAST), is pleased to announce that a second, American based, oil company has awarded MAST a USD $4,000,000 contract to evaluate our nanoparticles as a potential tracer element in their secondary oil recovery operations. Under the agreement, MAST will develop and deliver a client specific, proof of concept.
