摘要:
Certain aspects of a method and system for mitigating effects of pulling in multiple phase locked loops in multi-standard systems may include selecting an input frequency range of operation at a voltage controlled oscillator based on a particular wireless band of operation in a system that handles a first wireless communication protocol and a second wireless communication protocol. An image rejection mixer may be enabled to generate an output signal for the particular wireless band of operation based on mixing a plurality of received signals within a selected frequency range. An in-phase (I) component and a quadrature (Q) component of the generated output signal may be generated by utilizing a RC-CR quadrature network.

Catalytically active (001) ceria substrates or buffers are used to modify the structure of the epitaxial high temperature superconductor YBa2Cu3O7. The catalytically active substrate has a small lateral grain size, typically less than 50 nm, to provide a high density of nucleation sites, at some of which nucleate a previously unknown metastable phase. The modification is achieved by catalytically assisted synthesis of the metastable phase. The new phase, a long-period (3.5-nm) perovskite, intercalates into the YBa2Cu3O7 matrix without negatively affecting the critical temperature of the film. Analysis of electron microscopy and synchrotron X-ray diffraction data allow identification of the phase as a long-period YBa2Cu3O7 derivative formed through short-range cation displacement. The films, from about 100-nm to about 1000-nm thick, exhibit strong enhancement of the critical current density, reaching a maximum of approximately 4.2 MA/cm2 at 77 K.

Droplets or plugs within multiphase microfluidic systems have rapidly gained interest as a way to manipulate samples and chemical reactions on the femtoliter to microliter scale. Chemical analysis of the plugs remains a challenge. It has been discovered that nanoliter plugs of sample separated by air or oil can be analyzed by electrospray ionization mass spectrometry when pumped directly into a fused silica nanospray emitter nozzle. Using leu-enkephalin in methanol and 1% acetic acid in water (50:50 v:v) as a model sample, we found carry-over between plugs was
