  PDMPO (2 (4 pyridyl) 5 ((4 (2 dimethylaminoethylaminocarbamoyl)methoxy)phenyl)oxazole), has unique silica specific fluorescence and is used in biology to understand biosilicification. This 'silicaphilic' fluorescence is not well understood nor is the response to local environmental variables like solvent and pH. We investigated PDMPO in a range of environments: using UV vis and fluorescence spectroscopy supported by computational data, (SPARC, molecular dynamics simulations, density functional theory calculations), dynamic light scattering and zeta potential measurements to understand the PDMPO silica interaction. From absorption data, PDMPO exhibited a pKa of 4.20 for PDMPOH22+ to PDMPOH+ . Fluorescence emission measurements revealed large shifts in excited state pKa values with different behaviour when bound to silica (pKa of 10.4). PDMPO bound to silica particles is located in the Stern layer with the dye exhibiting pH dependent depolarising motion. In aqueous solution, PDMPO showed strong chromaticity with correlation between the maximum emission wavelength for PDMPOH+ and dielectric constant (4.8 80). Additional chromatic effects were attributed to changes in solvent accessible surface area. Chromatic effects were also observed for silica bound dye which allow its use as a direct probe of bulk pH over a range far in excess of what is possible for the dye alone (3 5.2). The unique combination of chromaticity and excited state dynamics allows PDMPO to monitor pH from 3 to 13 while also reporting on surface environment opening a new frontier in the quantitative understanding of (bio)silicification.
Price Waterhouse Cooper (PwC) 2018 Global Economic Crime and Fraud Survey in Vietnam finds that 52% of Vietnamese enterprises had experienced economic crime in the past two years. This is the first PwC survey in Vietnam. According to the survey, this crime rate is higher than the average in Asia Pacific's 46% and the global rate of 49%. Even though 40% of the asked people said they hadn't encountered any criminals, it's highly likely that the crimes just haven't been exposed yet. The most common crime in Vietnam is embezzlement with 40% votes and bribes and corruption with 36%. 11% of the asked people don't know or don't want to say. About 53% of the criminals in major cases are insiders with 61% of them are low level or middle level managers. 32% of the surveyed said they suffered more than USD100,000 in damage not to mention damage to reputation and business relations. Marcus Paciocco from PwC Vietnam said some measurable financial losses included legal costs or actual loss [Read more.] about BUSINESS NEWS IN BRIEF 21/11
