The Coefficient of the Voltage Induced Frequency Shift Measurement on a Quartz Tuning Fork
Sensors, 2014 We have measured the coefficient of the voltage induced frequency shift (VIFS) of a 32.768 KHz quartz tuning fork. Three vibration modes were studied: one prong oscillating, two prongs oscillating in the same direction, and two prongs oscillating in ...

Driveless Gyroscope Response of a Quartz Piezoelectric Vibratory Tuning Fork
, 2015 In this paper, we report on the observation of a gyroscope response in the absence of drive oscillator circuitry in a single ended quartz piezoelectric tuning fork. The tuning fork gyroscope was fabricated by conventional photolithography and wet etching

Advanced Materials, EarlyView.Highly water‐soluble dicationic bis(indolium) dyes have been prepared, showing excellent two‐photon absorption and light emission. Their fluorescence behavior discloses an unusual increasing blue shift with increasing solvent polarity, which, in parallel, is beneficial for enhanced detection in biological media.

Advanced Materials, EarlyView.Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the

An Adjustable Tuning Fork [PDF]
The Journal of the Acoustical Society of America, 1938 A portable tertiary frequency standard, adjustable over a small range, is described. The frequency determining element is a valve-maintained tuning fork, adjustment of whose frequency over a relatively small range is accomplished by changing the position of movable weights on the prongs.

Resolving the Structural Duality of Graphene Grain Boundaries
Advanced Materials, EarlyView.Cantilever ncAFM resolves the atomic structure of grain boundaries in graphene, revealing coexisting stable and metastable types. Both contain pentagon/heptagon defects, but metastable GBs show irregular geometries. Modeling shows metastable GBs form under compression, exhibiting vertical corrugation, while stable GBs are flat.
