Azonia spiro polyaza macrocycles containing biphenyl subunits as anion and cation receptors
Elsevier (2011-06-24)The reaction of N-Boc triprotected cyclam with bis(chloromethyl)biphenyl followed by the corresponding deprotection of the nitrogen atoms allows the preparation of receptor 3 containing an azonia spiro subunit. This receptor ... -
Bacterial base excision repair enzyme Fpg recognizes bulky N7-substituted-FapydG lesion via unproductive binding mode
(2012-07-18)Fpg is a bacterial base excision repair enzyme that removes oxidized purines from DNA. This work shows that Fpg and its eukaryote homolog Ogg1 recognize with high affinity FapydG and bulky N7-benzyl-FapydG (Bz-FapydG). The ... -
In-situ laser synthesis of rare earth aluminate coatings in the system Ln-Al-O (Ln = Y, Gd)
Elsevier (2011)Laser zone melting (LZM) was employed in this work to prepare Ln-Al-O coatings on polycrystalline Al2O3 substrates, using the corresponding mixtures of powdered rare-earth oxides and Al2O3 as starting materials. In-situsynthesis ... -
New vanadium doped calcium titanate ceramic pigment
Elsevier (2011-12)In this paper a new pink vanadium doped calcium titanate Ca(VxTi1−x)O3 ceramic pigment in conventional ceramic glazes is obtained by ceramic route and characterized. The limit of solid solution is near by x = 0.2, higher ... -
Solid solutions of mixed metal Mn3−xMgxFe4(PO4)6orthophosphates: colouring performance within a double-firing ceramic glaze
Elsevier (2011-03)Solid solutions of mixed metal Mn3−xMgxFe4(PO4)6 orthophosphates (x = 0, 0.5, 1, 1.5, 2, 2.5, and 3) were prepared for the first time (from coprecipitate powders calcined up to 1000 °C) and characterized by thermal analysis, ...
