The biopolymers chitin (CTN) and chitosan (CTS) were functionalized with APTES (3-aminopropyltriethoxysilane) in order to enhance its adsorption potential for sunset yellow dye (SYD). The functionalization was proved by several techniques like FTIR (Fourier transform infrared spectroscopy), XRD (X-ray diffraction), N2 adsorption/desorption isotherm...
A comparative approach for the surface silylation of nanofibrillated cellulose (NFC) in water is proposed through an environmentally friendly sol-gel route based on alkoxysilanes. NFC suspensions were freeze-dried under controlled conditions in the presence of methyltrimethoxysilane used as a model alkoxysilane. Two different protocols that involve...

An easily prepared series of phenylindenyldihydridosilyl ruthenium complexes () was obtained by reaction of tertiary silanes with the commercially-available [RuCl(3-phenylindenyl)(PPh3)2] (). The [RuH2(3-phenylindenyl)(SiEt3)] () complex was shown to be highly efficient (1.5 mol%) in the ortho-selective borylation of pyridyl substrates, with yields...

• Leaching of biocide treated wood leads to reduced effectiveness and potential threat to the environment. • Therefore the effectiveness of organosilicons as protective systems of biocides was evaluated. Scots pine sapwood specimens were impregnated with solely organosilicons and biocides as well as with combinations of both.• The biocides 3-iodo-2...
The increasing emission of CO_2, due to the growing power consumption, requires more and more efforts to replace fossile fuels by sophisticated no-emission systems in power generation. Using photovoltaics is one possible option. Producing electricity by solar energy, photovoltaics may contribute to a significant reduction of CO_2 emissions. The bas...
Cross sections are provided for most important collision processes of the Silicon-Hydrides from the ''Silane-family'': SiH_y (y = 1 - 4) molecules and their ions SiH_y"+, with (plasma) electrons and protons. The processes include: electron impact ionization and dissociation of SiH_y, dissociative excitation, ionization and recombination of SiH_y"+ ...
