Sentences with phrase «by external magnetic fields»

For targeted non-invasive medicine delivery, these nano - swimmers could be coated with medicine, injected into the bloodstream and roughly steered by external magnetic fields.

Made by Shuhei Miyashita and colleagues at Massachusetts Institute of Technology, a 1.7 - centimetre - long origami robot made of plastic and containing a magnet can be «programmed» by an external magnetic field.

A tiny robot made of plastic can be «controlled» by an external magnetic field

Instead of permanently depositing particles through immunoaffinity, anti-EpCAM coated magnetic microparticles were trapped over the untreated PDMS surface by an external magnetic field and were then released by readily removing the magnet for CTC collection.

«The influence of laser light on the state of the atoms can be compared to the magnetization of solid crystals by an external magnetic field in classical physics,» Dr. Christian Groß, leader of the project, explains.

That non-Markov machines exist is shown by a simple example: the magnetization of a piece of iron immersed in an oscillating magnetic field depends on the values of the external field in the past, as well as in the present.

We present a third, distinct bonding mechanism: perpendicular paramagnetic bonding, generated by the stabilization of antibonding orbitals in their perpendicular orientation relative to an external magnetic field.

But a strong external magnetic field can reduce that resistance by bringing the magnetic moments into alignment.

In this material, magnetic moments and electric charges simultaneously play a part in the excitation, and therefore both can be influenced by one single external field.

External magnetic fields exert forces on them, levitate them against gravity and keep them together; the atoms are trapped in a magnetic cage with invisible walls formed by magnetic fields.

The capsule is used with a fixed external magnet and its position is tracked precisely by measuring the strength and direction of the magnetic field it experiences.

They plan to make a «smart material» by adding chemical groups that respond to incident light, magnetic field, or applied potential, leading to external control of the transformation that creates pores in the otherwise dense material.

There are two main theoretical models, one based on small magnetite particles that may reorient in an external magnetic field and the other based on the idea that upon photo excitation a certain type of molecules in the eye of a bird support a radical pair formed by two electrons which evolve under the joint action of the Zeeman interaction with the external magnetic field and the hyperfine interaction with the supporting molecule.

Another apparatus associated with this invention includes a receiver resonator including at least two loop resonators capable of resonating in the presence of an external non-radiative magnetic field, the at least two loop resonators being disposed in such that the magnetic field received by each is substantially orthogonal to that received by the other.
