MnO2 has been widely studied as the pseudo-capactive electrode material of high-performance supercapacitors for its large operating voltage, low cost, and environmental friendliness. However, it suffers from low conductivity and being hardly handle as the electrodes of supercapacitors especially with flexibility, whic…
We investigated electron-beam lithography with an aberration-corrected scanning transmission electron microscope. We achieved 2 nm isolated feature size and 5 nm half-pitch in hydrogen silsesquioxane resist. We also analyzed the resolution limits of this technique by measuring the point-spread function at 200 keV. Fur…
The controlled synthesis of highly crystalline MoS2 atomic layers remains a challenge for the practical applications of this emerging material. Here, we developed an approach for synthesizing MoS2 flakes in rhomboid shape with controlled number of layers by the layer-by-layer sulfurization of MoO2 microcrystals. The o…
Zinc is proposed as an exciting new biomaterial for use in bioabsorbable cardiac stents. Not only is zinc a physiologically relevant metal with behavior that promotes healthy vessels, but it combines the best behaviors of both current bioabsorbable stent materials: iron and magnesium. Shown here is a composite image o…
Background Metamaterials (MMs) are smartly engineered structures with rationally designed, nanostructured building blocks that allow us to build devices with distinct responses to light, acoustic waves, and heat flows that are not attainable with naturally available materials. Advances The latest developments have sho…
This report describes the development of an updated Online Guide to Luminaire Supports. The Guide is a web-based content management system for luminaire support systems that allows full viewing, submission, management, and reporting services to its users (e.g., State department of transportation (DOT) personnel, const…
Pollen samples from Páramo plants collected by A.M. Cleef and from various herbaria. The collection is used as a reference collection for palynological research.
The elliptical magnetic mirror scheme for guiding fast electrons for Fast Ignition proposed by Schmitz (H.Schmitz et al., {\it Plasma Phys.Control.Fusion},{\bf 54} 085016 (2012)) is studied for conditions on the multi-kJ scale which are much closer to full-scale Fast Ignition. When scaled up, the elliptical mirror sch…
A nonstandard system of differential equations describing two-species phase\nsegregation is considered. This system naturally arises in the asymptotic\nanalysis recently done by Colli, Gilardi, Krejci and Sprekels as the diffusion\ncoefficient in the equation governing the evolution of the order parameter\ntends to ze…
The apertureless SNOM mapping of the slightly-doped 4H-SiC epitaxial layer\ngrown on a heavily-doped 4H-SiC substrate was performed with a cleaved edge\ngeometry. ASNOM images taken at the light frequencies of a $C^{13}O_{2}^{16}$\nlaser show a clear contrast between the substrate and the epitaxial layer. The\ncontras…

This dissertation proposed the development of a quantification method, by microscopy, of the microconstituent Martensite-Austenite (MA) in a High Strength Low Alloy (HSLA) steel of the API5LX80 class. Images were obtained by Optical Microscopy (OM) and Scanning Electron Microscopy (SEM), in secondary electron (SE) and…
Computational Fluid Mechanics and Heat Transfer, third edition, by R. H. Pletcher, J. C. Tannehill, and D. A. Anderson, CRC Press, Boca Raton, 2013. Computational tools and techniques have evolved ...

At the time of Becquerel’s discovery the nature of these “radioactive” emissions was completely unknown, as was their connection to the nucleus of the atom, whose existence would not be discovered for another decade. Becquerel’s name is now attached to one important SI unit used in nuclear science, the Becquerel (Bq),…
The treatment of diseased vasculature remains challenging, in part because of the difficulty in implanting drug-eluting devices without subjecting vessels to damaging mechanical forces. Implanting materials using adhesive forces could overcome this challenge, but materials have previously not been shown to durably adh…
Bionanotechnology is multidisciplinary knowledge gained at the intersection of biology and nanotechnology. Certainly, biology operates in the nanoscale regime, using natural processes that occur in the nanoscale, by convention, under 100 nm in dimension. Therefore, bionanotechnology relates to those subtopics in the b…

Виконано аналіз вітчизняних нормативноправових актів, документів Міжнародного агентства з атомної енергії та директив Європейського Союзу, в яких наведено вимоги та рекомендації щодо циклотронного виробництва ізотопів та їх застосування в діагностиці методом позитрон-емісійної томографії. Встановлено потреби в удоскон…
Виконано аналіз впливу початкових та граничних умов на термоудар корпусу реактора на прикладі енергоблока № 1 Южно-Української АЕС з реакторною установкою ВВЕР-1000/В-302. В результаті виконання серії теплогідравлічних розрахунків отримано найбільш консервативний сценарій для групи вихідних подій, пов’язаних з течами…
