Ecological method development for detecting N-nitrosodimethylamine in water using HPLC-PDAD
… liquid chromatographic method with photo-diode array detection (HPLC-PDAD) was investigated to detect sub-parts per billion concentrations of N-nitrosodimethylamine (NDMA) in drinking water and environmental water samples. This presents a practical and “green” option to analytical …

Characterization of a novel cellulose biosynthesis inhibitor, CBI28, in Gluconacetobacter xylinus
… Liquid Chromatograph-Mass Spectrometer/Photo Diode Array. Putative mutants were isolated but did not survive for further study. An ion with the expected mass of a CBI28-Biotin conjugate (552 m/z) was detected but not in sufficiently high concentrations for characterization. Metabolite …

Shinerbots: A robotic swarm navigation platform inspired by the golden shiner fish
… by vibration, senses ambient light using a photo diode, and senses neighbors using infrared. Scalable ways of charging and control of the swarm are achieved by a charging plate, as well as relayed system messages. A total of 85 robots were built. Experiments on the swarm behavior were …

Analysis of two single trait loci affecting flavonol glycoside accumulations in Arabidopsis thaliana natural variations
… First, high performance liquid chromatography photo diode array coupling with electro spray -ionization mass spectrometry (HPLC-PDA-ESI-MS) was employed to identify molecular mass of flavonoid aglycones and conjugate sugars. Second, high performance thin layer chromatography (HPTLC) was used to …

The destruction of the cyanobacterial toxin microcystin-LR by semiconductor photocatalysis.
… the toxin is not destroyed. Recently the use of photocatalysis was shown to rapidly degrade microcystin-LR even at high concentrations. The process involves the illumination of a titanium dioxide catalyst with ultraviolet (UV) light to produce highly oxidising hydroxyl radicals in solution. While …

Uptake and depuration of cyanotoxins in the common blue mussel Mytilus edulis.
… a high-performance liquid chromatography photo diode array (HPLC-PDA) analysis method for the detection of DA was optimised to enable the simultaneous detection of DA and nine cyanotoxins. This method was then utilised to determine cyanotoxin concentration in laboratory cyanobacteria …

Optically Controlled High Power High Speed Wide Band Gap Devices
… results, from which on-state resistance and peak photocurrent under different bias conditions and optical energies were calculated, and the potential of these devices was further explored. </p> <p> Analyses show that slow transient responses under low optical illumination occur due to trapping and …
