Modulation of the nanoscale motion rate of Candida albicans by X-rays

Sandor Kasas, María Inés Villalba

IntroductionPatients undergoing cancer treatment by radiation therapy commonly develop Candida albicans infections (candidiasis). Such infections are generally treated by antifungals that unfortunately also induce numerous secondary effects in the patient. ...

Superior visible light-mediated catalytic activity of a novel N-doped, Fe3O4-incorporating MgO nanosheet in presence of PMS: Imidacloprid degradation and implications on simultaneous bacterial inactivation

Stefanos Giannakis

Impressive Imidacloprid (IMD) degradation and bacterial inactivation were attained through the photocatalytic activation of peroxymonosulfate (PMS) via a novel, N-doped MgO@Fe3O4, under visible light. After complete characterization (XPS, XRD, FT-IR, FE-SE ...

Species identity, rather than species mixtures, drives cover crop effects on nutrient partitioning in unfertilized agricultural soil

Alexandre Buttler, Pierre Rémi Mariotte, Mathieu Raymond Santonja, Lucas Georges Jean-Paul Freund

Aims Previous cover crop studies mainly focused on the links between plant uptake and soil fertility, and there is a clear knowledge gap regarding the role of microbes in these processes. Our aim was then to better understand the effects of plant mixtures ...

Analysis of double cross-slip of pyramidal I < c plus a > screw dislocations and implications for ductility in Mg alloys

William Curtin, Rasool Ahmad

Solute accelerated cross-slip of pyramidal < c + a > screw dislocations has recently been recognized as a crucial mechanism in enhancing the ductility of solid-solution Mg alloys. In pure Mg, cross-slip is ineffective owing to the energy difference between ...

Regulation of adenylyl cyclase 5 in striatal neurons confers the ability to detect coincident neuromodulatory signals

Ursula Röthlisberger, Siri Camee van Keulen, Daniele Narzi

Author summary Adenylyl cyclases (ACs) are enzymes that can translate extracellular signals into the intracellular molecule cAMP, which is thus a 2nd messenger of extracellular events. The brain expresses nine membrane-bound AC variants, and AC5 is the dom ...

Impact of cation redox chemistry on continuous hydrothermal synthesis of 2D-Ni(Co/Fe) hydroxides

Andreas Stephan Lesch

Continuous hydrothermal flow synthesis (CHFS) is a facile, upscalable and cost-efficient synthetic method enabling the nanostructuring of advanced functional materials in steady conditions, i.e. not in batch synthesis. In this paper, we use CHFS to crystal ...

Selective, Fast-Response, and Regenerable Metal-Organic Framework for Sampling Excess Fluoride Levels in Drinking Water

Paul Joseph Dyson, Kyriakos Stylianou, Ngoc Tú Nguyên, Andrzej Gladysiak, Fatmah Ebrahim, Serhii Shyshkanov

Prolonged consumption of water contaminated with fluoride ions (F-) at concentrations exceeding 1.5 ppm can lead to considerable health implications, particularly in children and developing embryos. With irreversible and potentially severe forms of fluorid ...

MULTIPLICITY AND CONCENTRATION RESULTS FOR SOME NONLINEAR SCHRODINGER EQUATIONS WITH THE FRACTIONAL p-LAPLACIAN

We consider a class of parametric Schrodinger equations driven by the fractional p-Laplacian operator and involving continuous positive potentials and nonlinearities with subcritical or critical growth. Using variational methods and Ljusternik-Schnirelmann ...

Efficient Electrochemical Production of Peroxodicarbonate Applying DIACHEM (R) Diamond Electrodes

Christos Comninellis

The electrochemical synthesis of peroxodicarbonate was performed on boron-doped DIACHEM((R)) diamond anodes (BDD). The influence of various parameters was studied and promising conditions were determined in an undivided cell design by CONDIAS GmbH. The bes ...

Domain walls and defects in ferroelectric materials

Dragan Damjanovic

The results of recent studies of domain walls and their interaction with defects in BaTiO3, Pb(Zr, Ti)O-3, and BiFeO3 are discussed. The studies reveal why donor- and acceptor-doped Pb(Zr, Ti)O-3 behave differently, what is the role of stationary charged d ...

Brain metabolic alterations in mice subjected to postnatal traumatic stress and in their offspring

João Miguel das Neves Duarte, Alberto Corcoba

Adverse environmental and social conditions early in life have a strong impact on health. They are major risk factors for mental diseases in adulthood and, in some cases, their effects can be transmitted across generations. The consequences of detrimental ...

The Jones-Ray Effect Reinterpreted: Surface Tension Minima of Low Ionic Strength Electrolyte Solutions are caused by Electric Field Induced Water-Water Correlations

Sylvie Roke, Yixing Chen, Halil Ibrahim Okur

The surface tension of electrolyte solutions exhibits a minimum at millimolar electrolyte concentrations and then rises with increasing concentration. This minimum, known as the Jones-Ray effect, has been hotly debated over the past 80 years. If not consid ...

A Facile in Situ and UV Printing Process for Bioinspired Self-Cleaning Surfaces

Yves Leterrier, Sara Dalle Vacche, Marina Aymara González Lazo, Feyza Karasu Kiliç, Ioannis Katrantzis

A facile in situ and UV printing process was demonstrated to create self-cleaning synthetic replica of natural petals and leaves. The process relied on the spontaneous migration of a fluorinated acrylate surfactant (PFUA) within a low-shrinkage acrylated h ...

Surface trap mediated electronic transport in biofunctionalized silicon nanowires

Giovanni De Micheli, Sandro Carrara, Francesca Puppo

Silicon nanowires (SiNWs), fabricated via a top-down approach and then functionalized with biological probes, are used for electrically-based sensing of breast tumor markers. The SiNWs, featuring memristive-like behavior in bare conditions, show, in the pr ...

Mercury tissue residue approach in Chironomus riparius: Involvement of toxicokinetics and comparison of subcellular fractionation methods

Along with the growing body of evidence that total internal concentration is not a good indicator of toxicity, the Critical Body Residue (CBR) approach recently evolved into the Tissue Residue Approach (TRA) which considers the biologically active portion ...

On the use of shape constraints for state estimation in reaction systems

Dominique Bonvin, Julien Léo Billeter, Sriniketh Srinivasan

State estimation techniques are used for improving the quality of measured signals and for reconstructing unmeasured quantities. In chemical reaction systems, nonlinear estimators are often used to improve the quality of estimated concentrations. These non ...

Probability of observable flaw initiation at high cycle fatigue

Eugen Brühwiler, Vasileios Grigoriou

Fatigue evolution during the flaw initiation phase and under high cycle fatigue conditions is described at the level of the representative volume element by the probability that this element fails in a given period of time under given stimulus. This probab ...
