The surface of mercapto-functionalized mesoporous silica having a highly ordered open pore network was modified into a super-hydrophilic surface through a stepwise sulfonation process involving oxidation and ionization reactions. The initial mesoporous silica was prepared using an acid-catalyzed sol-gel reaction between tetraethoxysilane (TEOS) and 3-mercaptopropyltrimethoxysilane (MPTMS) in th...

Binding of transcription factors to DNA is a dynamic process allowing for spatialand sequencespecificity. Many methods for determination of DNA-protein structures do not allow for identification of dynamics of the search process, but only a single snap shot of the most stable binding. In order to better understand dynamics of DNA binding, as a protein encounters its cognate site, we have create...

To address the rising need of sustainable solutions in electronic devices, development electronically conductive composites based on lightweight but mechanically strong wood structures is highly desirable. Here, a facile approach for fabrication wood/polypyrrole through top-down modification native lignin followed by polymerization pyrrole cell wall. By sodium sulfite treatment under neutral co...

In this work membrane (proton exchange membrane) by using the blend polymers (polyethersulfone (PES), Expandable polystyrene (EPS), polyvenylidinefluride polymer (PVDF)) were prepared. This was modified adding organic sulfonic acid to solution precasting process, and sulfonated dipping it in diluted sulfuric (H2SO460%) post casting process. The sulfonation confirmed via FTIR spectra. characteri...
