A rapidly converging moment solution for electromagnetic seattenng by a single inductive post in a rectangular waveguide is obtained. The numerical results show good agreement with Marcuvitz’s data as ~ar as this data goes. Furthermore, Marcuvitz’s curves are extended to cover data for large posts. This new data should aflow one to design a simply constructed new type of narrow bandpass filter,...

Xylella fastidiosa is a fastidious Gram-negative bacterium that associated with several important plant diseases, and regulated as quarantine pest in many countries where strategies are implemented to prevent its introduction spread. To enact efficient measures, effective early detection of the pathogen essential, especially because global trade goods increases risks alien pathogens. this study...

We developed positron emission tomography (PET) detectors based on monolithic scintillation crystals and position-sensitive light sensors. Intrinsic depth-of-interaction (DOI) correction is achieved by deriving the entry points of annihilation photons on the front surface of the crystal from the light sensor signals. Here we characterize the next generation of these detectors, consisting of a 2...

Exact solutions for free vibration of thick rectangular orthotropic plates when their all edges are clamped sought through asymptotic analysis infinite systems without resorting to the usual truncation series solution. The use modified trigonometric functions made it possible obtain a general solution problem which has same form four cases symmetry quarter plate. Thus, an system linear algebrai...

The paper describes new approach of potentiostat for very low sensor current measurements. Recent potentiostats were used as measurement devices which were standalone and sensors were connected by a screened wire. These concepts are inconvenient for the presented very low current measurements. The new approach is based on the potentiostat circuitry integrated on a chip that should be directly c...

A rectangular thin elastic sheet is deformed by forcing a contact between two points at the middle of its length. transition to buckling with stress focusing reported for sheets sufficiently narrow critical width proportional length an exponent 2/3 in small thickness limit. Additionally, spring network model solved explore thick limit and validate scaling behavior The numerical results reveal t...

In this work we designed a MoS2 nanoplate-based nanoprobe for fluorescence imaging of intracellular ATP and photodynamic therapy (PDT) via ATP-mediated controllable release of (1)O2. The nanoprobe was prepared by simply assembling a chlorine e6 (Ce6) labelled ATP aptamer on MoS2 nanoplates, which have favorable biocompatibility, unusual surface-area-to-mass ratio, strong affinity to single-stra...

A tungsten trioxide (WO₃) nanoplate array is fabricated directly on the FTO/glass substrate and used as a platinum (Pt) nanoscale supporter for a highly efficient and low Pt-consumption counter electrode (CE) in dye-sensitized solar cells (DSCs). A Pt/WO₃ composite structure, with Pt nanoparticles having a diameter of 2-3 nm, increases the electrochemical catalytic activity in catalyzing the re...
