We report on a new method to characterize nanohydrodynamic properties at the liquid-solid interface relying solely on the measurement of the thermal motion of confined colloids. This equilibrium measurement of surface properties--equivalent in spirit to the passive microrheology technique used for bulk properties--is able to achieve nanometric resolution on the slip length measurement. Explorin...

Holography has extremely extensive applications in conventional optical instruments spanning optical microscopy and imaging, three-dimensional displays and metrology. To integrate holography with modern low-dimensional electronic devices, holograms need to be thinned to a nanometric scale. However, to keep a pronounced phase shift modulation, the thickness of holograms has been generally limite...

Electromagnetically induced transparency (EIT) on atomic D1 line of rubidium is studied using a nanometricthin cell with atomic vapor column length in the range of L = 400 800 nm. It is shown that the reduction of the cell thickness by 4 orders as compared with an ordinary cm-size cell still allows to form an EIT resonance for L = λ (λ = 794 nm) with the contrast of up to 40 %. Remarkable disti...

Nanometric flat lenses with three-dimensional subwavelength focusing are indispensable in miniaturized optical systems. However, they are fundamentally challenging to achieve because of the difficulties in accurately controlling the optical wavefront by a film with nanometric thickness. Based on the unique and giant refractive index and absorption modulations of the sprayable graphene oxide thi...

This study was focused on the experimental investigations about mechanical characteristics and tribological mechanisms of nanometric zirconia dental ceramics. A universal mechanical testing machine was used to test the threepoint flexural strength and the fracture toughness. A microhardness tester was used to test the Vickers hardness of the test specimens. An MRH-3 digital-display high-speed r...

We developed a high-resolution microscope based on three-dimensional structured illumination generated with two spatial light modulators. This setup enables both lateral resolution improvement by a factor two and axial localization of point like objects with nanometric precision.

Nanoscience emerged in the last decades of the 20th century with the general aim to determine those properties that appear when small particles of nanometric dimensions are prepared and stabilized.[...].

We have implemented the so-called λ-Zeeman technique (LZT) to investigate individual hyperfine transitions between Zeeman sublevels of the Rb atoms in a strong external magnetic field B in the range of 2500 − 5000 G (recently it was established that LZT is very convenient for the range of 10 − 2500 G). Atoms are confined in a nanometric thin cell (NTC) with the thickness L = λ, where λ is the r...
