Controlling the specific enrichment of multi-phosphorylated peptides on oxide materials: aluminium foil as a target plate for laser desorption ionization mass spectrometry

Hubert Girault, Liang Qiao, Manuel Alejandro Méndez Agudelo, Mohamad Hojeij, Hongyan Bi

A specific multi-phosphopeptide enrichment method is presented to complement current phosphopeptide isolation strategies that normally bias mass spectrometry analysis towards the detection of mono-phosphopeptides. An adsorption model is developed that show ...

Ferrate (Fe(VI)) Application for Municipal Wastewater Treatment: A Novel Process for Simultaneous Micropollutant Oxidation and Phosphate Removal

Urs von Gunten, Yun Ho Lee

A novel technology for enhanced municipal wasterwater treatment was assessed based on the dual functions of Fe(VI) to oxidize micropollutants and remove phosphate by formation of ferric phosphates. Second-order rate constants (k) for the reactions of selec ...

Aerobic granular sludge reactor technology - Aerobic granulation with different substrates

Samuel Lochmatter

Aerobic granular sludge is a promising alternative to traditional activated sludge basins in wastewater treatment plants (WWTP). Granular sludge has much better settling characteristics than activated sludge. Furthermore it can remove carbon, nitrogen and ...

Four new noncentrosymmetric salt-inclusion vanadates: (AX)2Mn(VO3)2 (A/X = Rb/Cl, Cs/Cl, Cs/Br) and (CsCl)2Cu(VO3)2

Wendy Lee Queen

Hybrid solids, made of chem. dissimilar components, have drawn much interest in advanced materials synthesis due to their structural versatility and multifunctional properties. For example, metal-org. frameworks (MOFs) have been extensively explored for th ...

Microbial processes in aerobic granules - can we use them to treat wastewater more efficiently?

Christof Holliger, Samuel Lochmatter, Graciela Gonzalez Gil

Aerobic granular sludge-based reactors represent an attractive alternative to conventional activated sludge systems. Compared to activated sludge, the use of aerobic granular sludge reactors is advantageous because (i) considerably less area is required fo ...

Kinetic studies on the first dihydrogen aquacomplex, [Ru(H2)(H2O)5]2+: Formation under H2 pressure and catalytic H/D isotope exchange in water

André Merbach, Lothar Helm, Gabor Laurenczy, Oleg Yazyev, Pascal Grundler

The ruthenium(II) hexaaqua complex [Ru(H2O)6]2+ reacts with dihydrogen under pressure to give the h2-dihydrogen ruthenium(II) pentaaqua complex [Ru(H2)(H2O)5]2+.The complex was characterized by 1H, 2H and 17O NMR: d H = -7.65 ppm, J HD = 31.2 Hz, d O = -80 ...

Towards the stereoselective synthesis of inherently chiral pseudorotaxanes

Natalie Renuka Banerji, Jérôme Lacour

Herein is reported an investigation towards the stereoselective synthesis of inherently chiral pseudorotaxanes. Chiral ammonium threads were readily prepared in five steps from racemic or enantiopure (M or P) salts of di-n-propyl-1,13-dimethoxyquinacridini ...
