- Description: The synthesis and characterization of an NIR absorbing acenaphthalene fused-ring-expanded aza-BODIPY dye are reported. In contrast with its naphtho-fused analogue, a stable complex is obtained when the corresponding phthalonitrile is used as the precursor. A comparison is made with the photophysical properties of 3,5-diphenyl-aza-dibenzoBODIPY. , Original publication is available at http://dx.doi.org/10.1039/C5RA14916A , Arbortext Advanced Print Publisher 9.1.510/W Unicode , Acrobat Distiller 8.1.0 (Windows); modified using iText� 5.3.3 �2000-2012 1T3XT BVBA (AGPL-version)

- Description: Tris-{1(4),8(11),15(18),22(25)-tetra(4-tertbutylphenoxy) phthalocyaninato} dineodymium (III) was synthesised and its nonlinear optical and fluorescence behavior was studied. Low fluorescence quantum yield (ФF = 0.03) was obtained with a fluorescence lifetime τF = 4.31 ns for this complex. Nonlinear optical parameters for the complex were determined using the Z-scan technique and the values of Im[χ(3)] and γ were of the order of 10−10 and 10−28 esu, respectively. Square wave voltammetry revealed three reduction and two oxidation couples for the complex. , Original publication is available at http://dx.doi.org/10.1016/j.ica.2014.11.029

- Description: All married women earning over R150 per month or over R34 per week have PAYE deducted from their wages. PAYE is income tax which is paid by workers on the "pay as you earn" system. Married men, however, pay tax only when their wages are over R500 per month. Single women pay tax only when their wages are over R350 per month. As you can see from the tables which follow, the tax on married women can be quite high. For example, if a married woman earns R220 per month, she will have R9,45 per month deducted from her wages for PAYE. (See Table No. 4). Married women who have children pay the same tax as if they haul no children, too. And there is no reduction in tax if you are over 60 years old, as there is for men. There is nothing can be done about this discrimination against married women until the government changes the tax rules.
