White electroluminescence (EL) was observed for the first time from diamond-like carbon (DLC) films at room temperature. ac voltages in excess of 200 V were applied to a metal-insulator-semiconductor (i.e., DLC)-insulator-metal device structure to observe EL. At an applied voltage of 235 V, the brightness and efficiency were 0.5 fl...
Pacific shrimp (Pandalus jordani) was washed repeatedly and the
eluted bacteria were enumerated and identified. Selected isolates
were tested for their adhesive properties.
Washing reduced the microbial load by 3.84 to 42.04%. The bacteria
which most resisted wash-off were Staphylococcus and Pseudomonas
spp. The easiest to wash off was Flavobacterium...
Submarine hydrothermal systems provide all of the
conditions necessary for the abiotic synthesis of organic
compounds, polymers, and simple cell-like organisms. An
analysis of the Archaean rock and fossil record shows that
fossils of simple organisms are found in rocks deposited in hydrothermal environments. Biochemical experiments have
shown that thermal...
