Some molecules change shape upon receiving photons of certain frequencies, but here we study light-induced deformation in ordinary dielectrics with no special optical effects. All dielectrics deform in response to light of all frequencies. We derive a dimensionless number to estimate when light can induce large deformation. For a structure made of soft dielectrics, with feature size comparable ...

A free-electron laser consists of an electron beam propagating through a periodic magnetic field. Today such lasers are used for research in materials science, chemical technology, biophysical science, medical applications, surface studies, and solid-state physics. Free-electron lasers with higher average power and shorter wavelengths are under development. Future applications range from indust...

Research on soft materials, including colloidal suspensions, glasses, pastes, emulsions, foams, polymer networks, liquid crystals, granular materials, and cells, has captured the interest of scientists and engineers in fields ranging from physics and chemical engineering to materials science and cell biology. Recent advances in rheological methods to probe mechanical responses of these complex ...

Focused-ion-beam ~FIB! milling has been used to structure magnetic nanoelements from 5 nm thick films of permalloy. We have used focused 30-keV Ga ions to define small arrays (6 mm 36 mm) of wires, circles, and elongated hexagons in the size range 100–500 nm. High-sensitivity magneto-optical measurements combined with atomic force microscopy show that very high quality magnetic nanostructures c...

Self-assembly is one of the crucial mechanisms allowing to design multifunctional materials. Soft hybrid materials contain components different nature and exhibit competitive interactions which drive self-organisation into structures a particular function. Here we demonstrate novel type magnetic material where molecular tilt can be manipulated through delicate balance between topologically-assi...

In this paper, the focus is on a new kind of biodegradable semi-interpenetrating polymer networks, which derived from ɛ-caprolactone, lactide, 1,4-butane diisocyanate and ethylenediamine and also its potential has been investigated in soft tissue engineering applications. The polymers were characterized by nuclear magnetic resonance (NMR) spectrometry, fourier transform infrared spectroscopy (F...

Soft magnetic films with a wide-range tunable ferromagnetic resonance frequency are suitable for miniaturization and multifunctionalization of microwave integrated circuits. Fabrication of these films for high-frequency applications is usually complicated and difficult. We demonstrate a simple method to fabricate patterned FeNi soft magnetic strip films by magnetron sputtering and photolithogra...
