The purpose of this study was to select an
alloy with a low driving force for nucleation
for a more in-depth study of the nucleation
of γ’-precipitates. To do this, three Ni-Cr-Al
alloys were chosen close to the solvus line
of a Ni-Cr-Al phase diagram, ensuring low
supersaturation and therefore...
This past week saw Germany hold federal elections for the Bundestag, the
national parliament. The center-right Christian Democrat Union (CDU)
gained 33% of the vote, essentially securing Angela Merkel’s fourth term
as chancellor. The Social Democrats (SPD) secured 20.5% votes, retaining

As American tech companies contend with strict scrutiny from Congress
in the wake of the 2016 election, several have already been harassed by
European regulators. During the past year, Amazon and Google were
slapped with massive fines, continuing a trend of EU hostility toward
major American tech companies.
The optical properties of spherical gold
nanoparticles are calculated using classical
electrodynamics. The wavelength corresponding
to maximum extinction shifts to
longer wavelengths as the size of the
nanoparticle is increased. The influence of
higher-order multipoles is evident for large
nanoparticles, making the spectra more
complex. When the shell thickness of...
