The liquid structure of aqueous solutions of five different imidazolium based gemini dicationic ionic liquids 1,n-bis(3-methylimidazolium-1-yl) alkane bromide (n being the length of the spacer alkyl chain), with propyl, pentyl, octyl, decyl and hexadecyl spacer chains has been studied using atomistic molecular dynamics simulations. While solutions with propyl and pentyl spacers are homogeneous,...

Jewawut merupakan serealia pangan lokal non-beras yang telah lama didomestikasi di seluruh dunia termasuk Sulawesi Barat, Indonesia sebagai alternatif pengganti beras. Ekstraksi DNA tahap awal penting dalam analisis berbasis molekuler. Metode ekstraksi berpengaruh terhadap kualitas dan kuantitasnya dihasilkan program pemuliaan tanaman jewawut. Penelitian ini bertujuan untuk mendapatkan metode e...

Through the descriptive and rheological characterization of worm-like micelles formed by N-hexadecyl-N-methylpyrrolidinium bromide and sodium laurate, the formation and properties of the worm-like micelles were affected by the concentrations of sodium laurate and temperature. Additionally, cryogenic transmission electron microscopy images further validated the formation of worm-like micelles.

Gold nanorods (AuNRs) are successfully employed in drug delivery, biosensors, and biotechnologies. Their wide success is due to their unique chemical properties, biocompatibility, easy, cheap versatile synthesis. In this framework, AuNRs were synthetized with the aim obtain strongly hydrophilic nanomaterials, suitable as delivery system. by seed mediated methods two steps. After careful purific...

Physico-chemical studies of some aqueous surfactant solutions were carried out by employing conductance, surface tension and spectrofluorometric techniques. From conductivity and surface tension measurements, critical micelle concentration (CMC), counter-ion association (α), equivalent conductance at infinite dilution (٨0), surface excess concentration (Γ), minimum area per molecule (Amin), sur...

In this study, different positively charged niosomal formulations containing sorbitan esters, cholesterol and cetyl trimethyl ammonium bromide were prepared by film hydration method for the entrapment of autoclaved Leishmania major (ALM). Size distribution pattern and stability of niosomes were investigated by laser light scattering method and ALM encapsulation per cent was measured by the bici...

An efficient and reproducible method for transformation depends on the competency of the organism. We have developed a simple method for the preparation of competent Escherichia coli, Kluyveromyces lactis, and Bifidobacterium sp. by using a buffer containing cetyl trimethyl ammonium bromide (CTAB) and permits efficient uptake of plasmid DNA and ligation-reaction products. Cells are harvested, w...
