Self-assembling molecules are central to a plethora of processes found in nature, biotechnology and even disease. The importance of the non-covalent interaction of monomers to the formation of fibrillar assemblies is evident in the repeated use of this mechanism throughout nature, from essential cellular processes suc…
While several organic compounds were detected in the vapor samples used in the reenactment of the preparation of mounts from the extracts of nuclear grade high-efficiency particulate air filter fiberglass samples, the most significant species present in the samples were methylene chloride, phenol, phenol-d6, and 2-flu…
The Andreev reflection spectra were studied for the first time in the magnetic superconductor Dy0.6Y0.4Rh3.85Ru0.15B4. It is found that an external magnetic field (up to 0.7 Hc2) is a strong stimulator of superconductivity in contrast with traditional superconductors with a singlet pairing. The ratio 2Δ/kBTc \approx 4…
This paper describes an active power filter (APF) control strategy, which eliminates harmonics and compensates reactive power in a three-phase four-wire power system supplying non-linear unbalanced loads in the presence of non-linear non-stationary currents. Empirical Mode Decomposition (EMD) technique developed as pa…
This paper analyzes the electrochemical response of the corrosive phenomenon caused by the entry of the chloride ion and, later, with the application of cathodic protection on steel embedded in mortar activated slag (AAS) and ordinary Type I Portland (OPC). The electrochemical study was performed by using half-cell po…
We investigated ultrafast carrier dynamics in graphene with near-infrared transient absorption measurement after intense half-cycle terahertz pulse excitation. The terahertz electric field efficiently drives the carriers, inducing large transparency in the near-infrared region. Theoretical calculations using the Boltz…
We compare the behavior of the magnetothermoelectric power (MTEP)in metallic ferromagnetic thin films of Ni80Fe20 (Permalloy; Py), Co and CrO2 at temperatures in the range of 100 K to 400 K. In 25 nm thick Py films and 50 nm thick Co films both the anisotropic magnetoresistance (AMR) and MTEP show a relative change in…
Due to their characteristic bright and stable photoluminescence, semiconductor nanocrystal quantum dots (NQDs) have attracted much interest as efficient light emitters for applications from single-particle tracking to solid-state lighting. Despite their numerous enabling traits, however, NQD optical properties are fru…

Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species.
Colloidal particle complexes are often characterized by small angle X-ray scattering (SAXS) techniques. The present work demonstrates SAXS analysis of inhomogeneous core-shell nanoparticles with complex shell morphologies. Different experimental techniques such as variation of particle composition and contrast variati…
The lack of structural symmetry which usually characterizes semiconductor quantum dots lifts the energetic degeneracy of the bright excitonic states and hampers severely their use as high fidelity sources of entangled photons. We demonstrate experimentally and theoretically that it is always possible to restore the ex…
On 28 May, a Japanese governmental advisory body laid out options for the mix of energy sources in 2030, along with projected effects on the economy and carbon dioxide emissions.
This report documents the testing of a urania (UO{sub 2.00}) sample as a baseline and the attempt to determine the melt point associated with 4 compositions of urania-ceria and urania-neodymia pseudo binaries provided by ORNL, with compositions of 95/5, and 80/20 and of (U/Ce)O{sub 2.00} and (U/Nd)O{sub 2.00} in the n…

Partial discharge (PD) measurements have emerged as a powerful diagnostic tool for condition monitoring of insulation in high voltage equipments. Study of PD patterns reveals the nature and severity of the defects present in the insulation. Nowadays online and onsite PD measurements are preferred to keep the equipment…
Metal complexes formed by the reactions keto and enol forms of isobutryl acetic acid hydrazide[IBAH] , 4-amino benzoic acid hydrazide[4-ABAH] and 4-cyano benzoic acid hydrazide[4-CBAH] with nickel(II) and copper(II) sulphate ions were prepared and characterized by elemental analysis, conductance measurements, i.r., an…
Generic glass formers exhibit at least two characteristic changes in their relaxation behavior, first to an Arrhenius-type relaxation at some characteristic temperature and then at a lower characteristic temperature to a super-Arrhenius (fragile) behavior. We address these transitions by studying the statistics of fre…
We report on the single-crystal-to-single-crystal transformation occurring over time in a layered organic molecular conductor based on BEDT-TTF. The process is connected with removal of solvent molecules from the complex anion layer resulting in concomitant partial irreversible conversion of the δ-(BEDT-TTF)4[OsNOCl5]…
A Typic Palexerult from northern Spain was subjected to acidity correction field tests over a period of 2 years. The experimental crop was a local rye variety and the amendments included gypsum, dolomite, limestone, and sugar foam waste, all at a 6000 kg ha–1 rate as calcium carbonate (CaCO3). General analyses were in…
