Complex colloidal fluids, such as emulsions stabilized by particles with complex shapes, play an important role in many industrial applications. However, understanding their physics requires a study at sufficiently large length scales while still resolving the microscopic structure of a large number of particles and of the local hydrodynamics. Due to its high degree of locality, the lattice Bol...

This study examined the effects of commonly used oxidants in sedimentary macroscopic charcoal analysis on two sediment cores from Thirlmere Lakes National Park, Southeast Australia. The cores, Lake Werri Berri (WB3) and Couridjah (LC2), span ~900 years 135,000 years, respectively. Charcoal Accumulation Rate (CHAR) for both area count was quantified using four different chemical treatments compa...

Long marine sedimentary cores can be effective in paleo-climate reconstruction. The present research aims at analyzing  the temporal variation of temperature as an important climate parameter and also variations in metal concentrations (As, Ba, Cd, Li, Mo, Mg, Mn, Na, Pb, Sr, Zn, Fe, Ca, Al) of two long sedimentary cores at the Persian Gulf back to the Holocene. The obtained results revealed th...

Nanophase Ti02 particles, with typical particle sizes in the range of 20-50 nm, have been synthesized using a microemulsion-mediated process. In this process, the aqueous cores ofwater/TritonX-100/exanol/ cyclohexane microemulsions have been used as constrained microreactors for the precipitation of precursor titanium hydroxide. The hydroxide particles thus formed were separated, dried, and cal...

We present results of rst epoch high resolution imaging observations of four extremely distant quasars. The sample includes the only two radio-loud quasars at redshift z > 4 known to the date of observa-The milliarcsecond scale structures of these quasars are dominated by compact cores. The two z > 4 quasars are unresolved on the baselines observed. We show that the apparently less prominent mi...

We show theoretically that a binary fluid characterized on a mesoscopic scale by purely repulsive short-range interactions without cores possesses an effective attraction between like particles. This "soft depletion effect" is a generic phenomenon driving a mixing-demixing transition in a binary system with pure repulsions.

A facile synthesis of monodispersed microparticles composed of superparamagnetic Fe(3)O(4) cores, SiO(2) shell, hierarchical γ-AlOOH periphery with Au nanoparticles is reported. These particles are found to be useful for protein immobilization and bear resemblance to daisy flowers, and are hereafter termed "nanoflowers".

The development of noble-metal free electrocatalysts is high importance for clean energy conversion applications. MoS$_2$ has been considered as a promising low cost catalyst the hydrogen evolution reaction (HER), however its activity limited by poor conductivity and abundance active sites. Moreover, suitability an effective other reactions, in particluar oxygen reduction (ORR), was hardly expl...

The ribosomal L12 protein gene of Sulfolobus solfataricus (SsoL12) has been subcloned and overexpressed in Escherichia coli. Five protein L12 mutants were designed: two NH2-terminal and two COOH-terminal truncated mutants and one mutant lacking the highly charged part of the COOH-terminal region. The mutant protein genes were overexpressed in E. coli and the products purified. The amino acid co...

The hepatitis B virus particle consists of an envelope carrying the surface antigen of the virus and an internal capsid consisting of the core antigen (HBcAg). The internal capsid contains the circular, partially dsDNA genome and the viral polymerase. Empty core particles have been produced in Spodoptera frugiperda cells using a recombinant baculovirus vector, YM1KTc, that expresses a 21.4K der...
