The cavitation bubble distribution (cavitation structure) is spatially inhomogeneous in ultrasonic field. A quasi-emulsion phenomenon of cavitation structure is reported in this paper. The inception process of cavitation bubble cloud in a thin liquid layer (the thin liquid layer is trapped between a radiating surface…
Since the discovery of Sc3N@C80 in 1999, much literature has focused on isolating metallic nitride clusters (M3N) entrapped within the smaller C80 cage. Over time, scientists (e.g., Echegoyen) have explored the same M3N clusters, but with bigger cage sizes, to expand the family of M3N@C2n. While HPLC has been the domi…
In this work we present our results of an approach to assess material property changes with time due to high temperature ageing in an isotropic conductive adhesive. A molecular model of an epoxy with similar primary chemistry is investigated by molecular dynamics simulations. By variation of crosslink density, one sup…
Time-varying loads negatively affect the properties and structure of materials. Structural failures typically occur at loads below the yield point. In this work, fatigue tests of welded joints of low-alloy steels were carried out in an asymmetric cycle at loads of 60 and 80% of the yield strength. The stress ratio was…
Recent clinical successes of transcranial focused ultrasound have occurred in the treatments of essential tremor, neuropathic pain, and Parkinson's disease, among others. We will present results of an investigation into the synthesis of multiple foci using iterative steering through multiple points and phased array co…
Flexible zinc-air batteries were fabricated using an inexpensive screen-printing technique. The anode and cathode current collectors were printed using commercial nanosilver conductive ink on a polyethylene terephthalate (PET) substrate and a polypropylene (PP) membrane, respectively. Air cathodes made of blended acti…
We evaluated the feasibility of thermal ablation in using a 230 kHz transcranial MRI-guided Focused Ultrasound (TcMRgFUS) system in three rhesus macaques. Thalamic targets were sonicated at 40–50s at 90–560 acoustic Watts. Focal heating sufficient to create an MRI-evident lesion was achieved in 4/6 targets where therm…
Proton Exchange Membrane Fuel Cells (PEMFC) are high-efficiency energy converters that can be deployed for mobile, transport and stationary applications in an eco-friendly manner. Nevertheless, their large-scale development requires further improvements, specifically regarding their lifetime in operation1. In abnormal…
Focused ultrasound (FUS) holds great promise for the development of effective and safe anticancer treatment protocols. FUS does not only allow to modulate the permeability of tumor vessels and enhance the extravasation of large molecules but to also locally trigger the release of their highly penetrating cargo. To uti…
Understanding dynamics of proteins has many practical implications in terms of finding a cure for many protein related diseases. Normal mode analysis and molecular dynamics methods are widely used physics-based computational methods for investigating dynamics of proteins. In this work, we studied dynamics of Hepatitis…
We employ an ultrasound wave field generated by one or more ultrasound transducers to organize large quantities of nanoparticles dispersed in a fluid medium into two-dimensional user-specified patterns. To accomplish this, we theoretically derive a direct method of calculating the ultrasound transducer parameters requ…
We fabricated planar perovskite solar cells used CH 3 NH 3 PbI 3-x Cl x for light harvesting to investigate effect of annealing on photovoltaic performance of fabricated device. The devices have an architecture of Glass/ITO/Pedot:PSS/Perovskite/PC 61 BM/Al. Layers of hole transport (Pedot:PSS), active and electron tra…
We name the Printable Electrochemistry for the development field of printable electrochemical devices [1,2]. Recently, we focus on several paper-based fully-printable electrochemical devices such as biofuel cell [3], biosensor [4] and reference electrode [5]. Paper-based biofuel cell have been attracted as a potential…
The article presents theoretical foundations for prediction of service life of mechanical products, based on the fatigue theory and fatigue limit. Ultimate amplitude and ultimate stress diagrams are presented. Wohler curve, characterizing material durability, is constructed on the results of the tests.
Controlled low-level covalent functionalization of single-wall carbon nanotubes (SWCNTs) has refocused the attention of the nanophotonics community on the use of SWCNTs as promising building blocks in photonic circuits due to their recently discovered property of room temperature single photon emission.1 Further, thes…
Vertically aligned carbon nanotube arrays (CNTs) are a nanoscale material that can be grown from the bottom up in a fast and controlled manner to form large microstructures. Combined with thin conformal coatings, we gain accurate control over the material properties of nano-porous CNT arrays. This paper deals with thr…
Volcano plots are frequently used in electrocatalysis to categorize and compare different catalysts and ultimately allow to predict the activity of novel materials on the basis of their binding energy for adsorbed intermediates.1 An accurate computation of the binding energy requires a good knowledge of the catalyst b…
In addition to the energy storage facilities based on high power technologies, Electric double layer capacitors(EDLC) are today"s candidate for power quality stabilization. However, its low energy density is often inhibiting factor for application of electric power industry. Hybrid supercapacitor is an promising energ…
We used the scanning electron microscopy and the electron backscattered diffraction to investigate a deformation relief and a crystallographic disorientation of a nickel [001] single crystal with {100} faces with a lateral incision. We identified that the lateral incision can change the shear domains distribution patt…
In this study, we focus on the sidewall of a single-walled carbon nanotube (SWNT) as a unique platform to probe ‘the smallest molecular assembly’ (dimers), which can be fully characterized microscopically, spectroscopically, and theoretically [1]. Theoretical calculations predicted that reactions of SWNT with aryl rad…
