A versatile luminescent probe for sensing and monitoring amyloid proteins
A modified lysine residue containing an environment-sensitive moiety was prepared through a straightforward synthesis, and its fluorescent properties were examined. The new fluorescent sensor, DMN-BocK, can monitor amyloid ...
A genomics approach identifies selective effects of trans-resveratrol in cerebral cortex neuron and glia gene expression
The mode of action of trans-resveratrol, a promising lead compound for the development of neuroprotective drugs, is unknown. Data from a functional genomics study were retrieved with the aim to find differentially expressed ...
Study of the magnetoelastic effect in nickel and cobalt thin films at GHz range using x-ray microscopy
We use surface acoustic waves of 1 and 3 GHz in hybrid piezoelectric-magnetic systems with either nickel or cobalt as a magnetic layer to generate magnetoacoustic waves and directly image them using stroboscopic x-ray ...
Ignition of CO2 methanation using DBD-plasma catalysis in an adiabatic reactor
In this work, a novel strategy of the use of dielectric barrier discharge (DBD) plasma-catalysis for exothermic reactions is presented. DBD-plasma is used as reaction ignitor, rather than the classical approach of continuous ...
Co-Ni-carbon flexible composite fibres for directional magnetic actuation
Flexible microcomponents are being widely employed in the microelectronic industry; however; they suffer from a lack of complex movement. To address this problem, we have developed flexible, electrically conductive, magnetic ...
On-the-Fly Synthesis of Freestanding Spin-Crossover Architectures With Tunable Magnetic Properties
Spin-crossover (SCO) molecular-based switches have shown promise across a range of applications since their discovery, including sensing, information storage, actuators, and displays. Yet limited processability remains a ...
pi-Donor/pi-Acceptor Interactions for the Encapsulation of Neurotransmitters on Functionalized Polysilicon-Based Microparticles
Bipyridinium salts, commonly known as viologens, are π-acceptor molecules that strongly interact with π-donor compounds, such as porphyrins or amino acids, leading their self-assembling. These properties have promoted us ...
Marcatge i identificació directa d'embrions de ratolí mitjançant l'adhesió de codis a la zona pel·lúcida
Due to the increase in the use of assisted reproduction techniques, improvement of sample traceability is essential. As an alternative to current systems of reproductive samples identification, our group work in the ...
Scaling Regimes of Active Turbulence with External Dissipation
Active fluids exhibit complex turbulentlike flows at low Reynolds number. Recent work predicted that 2D active nematic turbulence follows scaling laws with universal exponents. However, experimentally testing these predictions ...
Highly Specific and Wide Range NO2 sensor with color readout
We present a simple and inexpensive method to implement a Griess-Saltzman-type reaction that combines the advantages of the liquid phase method (high specificity and fast response time) with the benefits of a solid ...
Generation and Imaging of Magnetoacoustic Waves over Millimeter Distances
Using hybrid piezoelectric-magnetic systems we have generated large amplitude magnetization waves mediated by magnetoelasticity with up to 25 degrees variation in the magnetization orientation. We present direct imaging ...
Fall-back time for photo-ionized Cs atoms attached to superfluid He-4 nanodroplets
We have studied the dynamic evolution of a Cs atom photo-excited from 6s to 6p and 7s states on a helium droplet using time-dependent 4He-DFT simulations. Depending on the excited electronic state, the Cs impurity remains ...
Reactive Oxygen Species and Oxidative Stress in the Pathogenesis and Progression of Genetic Diseases of the Connective Tissue
Connective tissue is known to provide structural and functional 'glue' properties to other tissues. It contains cellular and molecular components that are arranged in several dynamic organizations. Connective tissue is the ...
Erratum: Rotating He-3 droplets [J. Chem. Phys. 152, 184111 (2020)]
Due to an error in the assigned value to the k = 0 component of the FFT of the screened Lennard-Jones potential, the DFT results shown in this article1 are affected to some extent. Here Fig. 1 presents the correct appearance ...
Elimination of interface energy barriers using dendrimer polyelectrolytes with fractal geometry
In this work we study conjugated polyelectrolyte (CPE) films based on polyamidoamine (PAMAM) dendrimers of generations G1 and G3. These fractal macromolecules are compared to branched polyethylenimine (b-PEI) polymer using ...
Antimalarial Activity of Orally Administered Curcumin Incorporated in Eudragit((R))-Containing Liposomes
Curcumin is an antimalarial compound easy to obtain and inexpensive, having shown little toxicity across a diverse population. However, the clinical use of this interesting ...
Gelatin-based nanoparticles as DNA delivery systems: synthesis, physicochemical and biocompatible characterization
The rapidly rising demand for therapeutic grade DNA molecules requires associated improvements in encapsulation and delivery technologies. One of the challenges for the efficient intracellular delivery of therapeutic ...
Enhanced diffusion barrier layers for avoiding degradation in SOFCs aged for 14000 h during 2 years
Electrolyte-cathode interfaces are critical regions of solid oxide fuel cells where important degradation phenomena are localized due to cation interdiffusion and reactivity. State-of-the-art barrier layers deposited by ...
Spatial Fluctuations of Loose Spin Coupling in CuMn/Co Multilayers
A detailed investigation of magnetic impurity-mediated interlayer exchange coupling observed in Cu 0.94 Mn 0.06 / Co multilayers using polarized neutron reflectometry and magnetic x-ray techniques is reported. Excellent ...
Acousto-optic deflectors in experimental neuroscience: overview of theory and applications
Cutting-edge methodologies and techniques are required to understand complex neuronal dynamics and pathological mechanisms. Among them, optical tools stand out due to their combination of non-invasiveness, speed, and ...
