The precise rotational manipulation of single cells or organisms is invaluable to many
applications in biology, chemistry, physics and medicine. In this article, we describe an …

Laser‐powder bed fusion (L‐PBF) is extensively adopted in the aerospace and automobile
industries for producing metallic components. The L‐PBF process involves rapid melting …

We observe distinct regimes of orbital angular momentum (OAM) transfer from two-
dimensional Bessel-shaped acoustic vortices to matter. In a homogeneous diphasic mixture …

Beams with fast and continuously-tunable orbital angular momentum (OAM) have potential
applications in classical and quantum optical communications, sensing, and in the study of …

In this work, we use multimode rate equations to investigate the asymmetric nonlinear gain
of a tunable three-section distributed Bragg reflector (DBR) laser. Our goal was to maintain …

Interdigitated transducers (IDTs) were originally designed as delay lines for radars. Half a
century later, they have found new life as actuators for microfluidic systems. By generating …

This paper describes the use of impulse control of an acoustic field to create complex and
precise particle patterns and then dynamically manipulate them. We first demonstrate that …

Over the past 36 years much research has been carried out on Bessel beams (BBs) owing to
their peculiar properties, viz non-diffraction behavior, self-healing nature, possession of well …

It has been found that the dielectric constants of transparent conductive oxides (TCOs) can
be adjusted in an extremely large range by tuning the carrier density. Due to the remarkable …

Acoustical tweezers can manipulate inanimate particles as well as living cells in liquid in 2D
using surface acoustic waves and in 3D using bulk acoustic waves. Here, we demonstrate a …
