Poly(carboxybetaine) Functionalization Proper restoration of zwitterionic balance after functionalization poly(carboxybetaine) brushes (pCB) is critical for pCB-biorecognition coatings with excellent antifouling properties. In article number 2201210, Ivana Víšová, Milan Houska, Hana Vaisocherová-Lísalová, and colleagues present a method using tailor-made mixtures agents allowing tuning the surf...

Design of particle accelerators with intense beams requires careful control of space charge problem. To obtain accurate treatment of the problem, solution of the Poisson's equation for electrostatic potential created by an arbitrary space charge distribution of the beam is required. Numerical routines developed for 2D and 3D space charge field calculation of high current beam are examined. Two ...

The M-type barium hexaferrite substituted with titanium, BaFe12−xTixO19, was synthesized from sodium carbonate flux and the obtained single crystals a maximum degree of substitution up to about x = 0.9 were characterized. XPS measurements carried out for identification side products in particular order assign valence states transition-metal constituents. Due aliovalent exchange iron(III) titani...

Intrinsically disordered regions (IDRs) play important roles in proteins that regulate gene expression. A prominent example is the intracellular domain of the Notch receptor (NICD), which regulates the transcription of Notch-responsive genes. The NICD sequence includes an intrinsically disordered RAM region and a conserved ankyrin (ANK) domain. The 111-residue RAM region mediates bivalent inter...

Weakly conducting dielectric liquid drops suspended in another dielectric liquid and subject to an applied uniform electric field exhibit a wide range of dynamical behaviours contingent on field strength and material properties. These phenomena are best described by the Melcher–Taylor leaky dielectric model, which hypothesizes charge accumulation on the drop–fluid interface and prescribes a bal...

The factors affecting the sound application of an anion-cation balance check to water quality analyses are investigated. ft is shown that the carbonate contribution to the total negative charge (in meq/l) is satisfactorily calculated from the formula [HCO3] = (Total Alkalinity )/50 below about pH l0 in samples in which carbonate is the only titratable component. It is also shown that ignoring t...

We present an analytical and experimental investigation into the origin of the open-circuit voltage in the solid-state dye-sensitized solar cell. Through Kelvin probe microscopy, we demonstrate that a macroscopically uniform electric field exists throughout the nanocomposite between the electrodes. Considering a balance between drift and diffusion currents, and between charge generation and rec...

The study of the battery charge process as the only power storage agent in off-grid systems is of significant importance. The battery charge process has different modes, and the battery in these modes is dependent on the amount of charge. In order to charge the battery in off-grid systems, two charge controllers including Pulse Width Modulation (PWM) and Maximum Power Point Tracker (MPPT) are c...

The effect of nonlinear interactions on the linear instability of shape fluctuations of a flat charged membrane immersed in a fluid is analyzed using a weakly nonlinear stability analysis. There is a linear instability when the surface tension reduces below a critical value for a given charge density, because a displacement of the membrane surface causes a fluctuation in the counterion density ...
