Background: Aflatoxin M1 (AFM1) is a toxic compound that could be found in milk and dairy products. AFM1 is the principle hydroxylated derivative of aflatoxin B1 (AFB1), formed in liver and excreted into the milk in the mammary glands of both human and lactating animals that have been fed with AFB1 contaminated diet. To the best of our knowledge, there is no report on stability of AFM1 during p...
P-channel Sil-@ex MOSFETs with peak Ge content x =0.3, 0.4, and 0.5 have been fabricated via MBE and experimentally characterized from room temperature down to 5K. Mobility enhancements relative to identically processed Si controls were largest at the lowest tempera2 tures. The highest mobility measured, pm = 1622 cm N.sec for the x = 0.3 SiGe device, was approximately a factor of four higher t...
Nano-silicon-based disordered carbon composites prepared by mechanical milling and pyrolysis have been examined as anodes of a lithium ion cell. Electrochemical measurements show that the charge–discharge capacity of disordered carbon composites incorporating both silicon-polyparaphenylene (Si-PPP) and silicon-polyvinyl chloride (Si-PVC) with differing silicon contents, decreases with increasin...
Ballistic-electron-emission microscopy (BEEM) is used to probe local conduction-band structure in strained Sil .xGq layers of pseudomorphic Sil-xGe#Si heterostmctires. The strain variation produced by a roughened Si l.xGex surface is seen as a variation of splitting between thresholds in BEEM spectroscopy. This splitting is directly related to the strain-induced conduction-band splitting in the...
We study the equilibrium shape, shape transitions and optimal size of strained heteroepitaxial nanoislands with a two-dimensional atomistic model using simply adjustable interatomic pair potentials. We map out the global phase diagram as a function of substrate-adsorbate misfit and interaction. This phase diagram reveals all the phases corresponding to different well-known growth modes. In part...
