Structure and Thermodynamics of Charged Colloids

1992
A multi-component MSA with non-additive radii (NAR-MSA) is applied to the study of monodisperse polyelectrolyte suspensions, described within the primitive model. The NAR-MSA is analytically solvable, and in practice permits an easy implementation of a rescaled MSA (RMSA).

Effect of Temperature on the Structure of Charged Membranes

The Journal of Physical Chemistry B, 2011
Interactions between charged and neutral self-assembled phospholipid membranes are well understood and take into account temperature dependence. Yet, the manner in which the structure of the membrane is affected by temperature was hardly studied. Here we study the effect of temperature on the thickness, area per lipid, and volume per lipid of charged ...

Surface-Charge Transport in a Multielement Charge-Transfer Structure

Journal of Applied Physics, 1972
A two-phase 14-stage transfer shift register has been built and operated which uses the surface-charge transistor structure to effect the transfer of signal charge from one stage to the next. This paper describes the structure and presents preliminary experimental results which characterize its operation as a digital shift register.

Charge Structure of the Nucleon

Physical Review, 1962
It is suggested that F/sub 1n/, the charge form factor of the neutron, is negative at low transferred momentum, and that the charge distribution of the proton is such that the bare proton is surrounded not only by a positively charged layer but also by a negatively charged layer because of the strong vacuum polarization resulting from the three-pion ...

Structure of the charged sheath at the plasma-charged body boundary

Journal of Experimental and Theoretical Physics, 2006
Based on a hydrodynamic plasma model that incorporates the inertia and temperatures of the plasma components, we have analytically and numerically solved the problem on the structure of the charged sheath at the plasma-charged body boundary. We formulate a criterion for the existence of a stationary charged sheath at the plasma-charged body boundary ...

Crystal structure and Charge Distribution of ErFeMnO4

Journal of Alloys and Compounds, 2000
The structure of synthetic YbFeMnO4 has been refined by single-crystal X-ray diffraction. Space group R\bar 3m, a = 3.4580 (1), c = 25.647 (3) Å, V = 265.59 (3) Å3, Z = 3. Yb is in octahedral coordination, whereas Fe and Mn are disordered on a single crystallographic type of trigonal bipyramid, in which the cation is off-centred from the basal plane ...

Surface charging of silicon dioxide/silicon structures

2011 - 14th International Symposium on Electrets, 2011
The surface of silicondioxide/silicon structures is charged with the tip of a cantilever in contact mode by application of a voltage. Then, the surface potential is measured contactless using the Kelvin option of an atomic force microscope. On the position of the charged domain a potential difference in relation to the uncharged region is found.

Structured electrons with chiral mass and charge

Science
Chirality is a phenomenon with widespread relevance in fundamental physics, material science, chemistry, optics, and spectroscopy. In this work, we show that a free electron can be converted by the field cycles of laser light into a right-handed or left-handed coil of mass and charge.

DNA structure: cations in charge?

Current Opinion in Structural Biology, 1999
Recent X-ray diffraction, NMR spectroscopy and molecular mechanics results suggest that monovalent cations selectively partition into the minor groove of AT-tracts in DNA. These observations are consistent with DNA deformation by electrostatic collapse around areas of uneven cation density.

Effect of the neutron charge on the charge structure of light nuclei

Il Nuovo Cimento A, 1980
By considering an effective charge on the neutron inside the nucleus, we study the effect of the neutron charge structure (GEn) on the charge form factors ofs-shell nuclei. With a newly established form (particularly, the modified Clementel-Villi form) forGE/n, the calculated results for4He and3He are found in fairly good agreement with recent ...
