Gyroscopes based on nitrogen-vacancy centers in diamond
, 2012 We propose solid-state gyroscopes based on ensembles of negatively charged nitrogen-vacancy (${\rm NV^-}$) centers in diamond. In one scheme, rotation of the nitrogen-vacancy symmetry axis will induce Berry phase shifts in the ${\rm NV^{-}}$ electronic ...

Peptomer Linkers Enable Kinetic Control over Co‐Delivery of Multiple Chemotherapeutics
Advanced Healthcare Materials, EarlyView.A key challenge in combinatorial chemotherapeutic drug delivery is independent control over release kinetics, especially with drugs of similar size and structure. Here, peptoid substitutions to proteolytically degradable peptides enabled the design of fast and slow‐releasing drug linkers.

Miniaturizing optical gyroscopes [PDF]
Science, 2017 Applied Optics Gyroscopes are used in many applications and can be found in devices such as position sensors, inertial navigation systems, and motion stabilizers. Science museum toys consisting of spinning wheels and gimbals illustrate the general principle of operation, but decades of research have focused on their miniaturization and developing ...

Vulnerability of MEMS Gyroscopes to Targeted Acoustic Attacks
IEEE Access, 2019 The goal of this paper is to assess the vulnerability of MEMS-based gyroscopes to targeted ultrasonic attacks. Towards this objective, a surface micromachined planar MEMS gyroscope is fixed in space and subjected to ultrasonic waves with frequencies near

Advanced Materials, EarlyView.This study demonstrates a self‐assembly process to generate free‐standing piezoelectric nanomembranes, forming ultracompact microtubular acoustic wave sensors and actuators. The miniaturized 3D piezoelectric platform reported in this work can be applied in telecommunication, energy harvesting, and acoustofluidics. Moreover, the 3D self‐assembly can add

Advances toward fieldable atom interferometers
Advances in Physics: X, 2022 We review the field of atom interferometer inertial sensors. We begin by reviewing the path integral formulation of atom interferometers and then specialize the treatment to light-pulse atom interferometers and, in particular, gravimeters and gyroscopes.

New Upper Limit of Terrestrial Equivalence Principle Test for Rotating Extended Bodies
, 2003 Improved terrestrial experiment to test the equivalence principle for rotating extended bodies is presented, and a new upper limit for the violation of the equivalence principle is obtained at the level of 1.6$% \times 10^{\text{-7}}$, which is limited ...

Transactions of the American Mathematical Society, 1922 The problem which led to the results of this paper was the following.* Consider a gyroscopet which is rotating with high velocity about its axis, the center of gravity, 0, being fixed in space. Let a couple, 9), be applied. The axis of the gyroscope will in general describe a cone, S, whose vertex is at 0.
