Anomalous changes of physical properties are observed in an abrupt bulk-to-discrete transition in layered silver alkanethiolate (AgSCn, n = 1–16). A critical chain length of ncr = 7 marks the sharp boundary between the bulk (uniform, n ≥ 7) and d

We report a systematic study of melting of layered lamella of silver alkanethiolates (AgSCn). A new synthesis method allows us to independently change the thickness of the crystal in two ways-by modulating chain length (n = 7-18) and by stacking thes

Approaching the ultimate limits of material sizes provides a route for designing new functional materials with extraordinary properties. We report the first systematic synthesis and characterization study of a wide range of highly ordered silver alka

Anomalous melting transitions are observed on dimethyl dioctadecyl ammonium bromide (DODAB) using a fast-scanning liquid calorimeter. A single transition is observed at low scan rates (1 K/min) while up to four peaks are evident at high scan rates (6

We report the synthesis of silver-decanethiolate (AgSC10) lamellar crystals. Nanometer-sized Ag clusters grown on inert substrates react with decanethiol vapor to form multilayer AgSC10 lamellar crystals with both layer-by-layer and in-plane ordering

We characterize and compare the reaction of alkanethiol with Ag continuous planar thin films and Ag islands on inert substrates. Ag islands generate a significantly larger (3-fold) amount of alkanethiolate than continuous Ag films at comparable condi

During package qualification, a 5-die-stacked chip scale package was being marginally triggered on high stand-by current collectively known as Power ICCS failure. Affected lots are subjected to 3x reflow at 240°C. Post reflow failures include blown_

The increasing demand for high end electronic devices incorporating multiple functions in a small form factor leads to the widespread use of Stacked Chip Scale Packaging (SCSP) in the semiconductor industry. Multiple die stacking in various combinati

The total enthalpy of reaction and heat capacity to 850 °C were measured using differential scanning nanocalorimetry (nano-DSC) for the reaction of a nickel and silicon bilayer at heating rates up to 106 K/s. Exothermic dips in heat capacity attribu
