The nucleation of crystalline materials is a hotly debated subject in the physical sciences. Despite the emergence of several theories in recent decades, much confusion still surrounds the dynamic processes of nucleation. This has been due in part to the limitations of existing experimental evidence. Charged colloidal suspensions have been used as(More)
The antifreeze protein (AFP) reduces the growth rates of the ice crystal facets. In that process the ice morphology undergoes a modification. An AFP-induced surface pinning mechanism, through matching of periodic bond chains in two dimensions, enables two-dimensional regular ice-binding surfaces (IBSs) of the insect AFPs to engage a certain class of ice(More)
Lead free thick film NTC (negative temperature coefficient) thermistors based on perovskite-type semiconducting materials of different compositions BaFe<inf>0.9</inf>Sn<inf>0.1</inf>O<inf>3</inf> + BaBiO<inf>3</inf>, and BaFe<inf>0.9</inf>Sn<inf>0.1</inf>O<inf>3</inf> + BaBiO<inf>3</inf> + CuO were fabricated on alumina substrate by screen printing(More)
The fluorescence of lima bean trypsin inhibitor is due to a single tyrosine residue at position 69. The lifetime of this tyrosine fluorescence is 620 +/- 50 ps (mean +/- SD) and is little affected by addition of 0.88 M citrate, an efficient quencher of tyrosine fluorescence. The steady-state emission intensity is also only weakly reduced by the quencher.(More)
