Mensah was born in 1950 in Kumasi, Ghana. He could read newspapers and
speak French fluently and was the main contact person between his
father’s business and french clients. He also won different levels of
the National French Contest (Le Grand Concours) between 1968 and 1970.
The condensed-matter physics world was shaken up when high-temperature
superconductivity was reported in a copper oxide material in 1986 by
Alex Müller and Georg Bednorz. Their discovery not only led to an
immediate Nobel Prize in 1987, it also created the „Woodstock of
Physics“ at the following American Physical Society’s March Meeting,
which in turn made it onto the New York Times front page. This was the
start of the “fever of high Tcs”, a world-wide scientific
undertaking towards achieving room temperature superconductivity. Some
thirty years later and counting, the copper oxides keep posing puzzles
to physicists. A universally agreed-upon explanation of their electronic
properties has not yet been reached.
Scientists in Australia have developed a new approach to reducing the
errors that plague experimental quantum computers; a step that could
remove a critical roadblock preventing them scaling up to full working
Materials with a defined nanostructure can have surprising properties.
One example is a lightweight ceramic that springs back to its original
shape, like a sponge, after being compressed. One day, such materials
could be used in ultrasensitive tactile sensors or advanced batteries. A
team of engineers from ETH Zurich and the California Institute of
Technology (Caltech) in Pasadena has now developed a new way of
manufacturing such materials.
Scientists from the RIKEN Cluster for Pioneering Research and RIKEN Center for Emergent Matter Science have succeeded, in collaboration with international partners, in creating an ultrathin organic solar cell that
is both highly efficient and durable. Using a simple post-annealing
process, they created a flexible organic cell that degrades by less than
5 percent over 3,000 hours in atmospheric conditions and that
simultaneously has an energy conversion ratio—a key indicator of solar
cell performance—of 13 percent.
