Three informative items came across my desk that I wish to
share. These are either benchmarks of progress or inflection
points for the next technology generation.
The first is about using statistics to provide an interpretation
of the uncertainty of a measurement. It may have larger
impact on small statistical samples. This article might have been
useful for me in reporting results of one aspect from my
doctoral thesis (structure-activity relationship).
Most of us who have some familiarity with DNA know it as
a double-stranded helical structure revealing the chemical
basis of biological differences. It is interesting to read the
speculation of Claude Gagna in “Reactions” 6-4-18 about
non-canonical nucleic acid structures and their biological
Finally, I was pleased to see discussion on tandem solar
cells with perovskites which may pave the way for
higher efficiencies that will get me interested in placing
solar panels on my northern city home.

Readers of this blog will recognize my fascination with
Deming’s short reports on statistics. Here he helps us see
our way to understand how some data with small sample
size can be interpreted and some questions you can ask

I liked the way this was handled and reemphasized.
An original commentary on a new chemical finding was
remarked in Reactions section not long afterwards.
This line of thinking has broad implications as well.
There should be a practice in journal publication that
does this sort of follow-up to bring strong ideas up
and share them with the chemical community. I emphasize
this for grad students and post-docs to build ideas of this
nature in your research notebooks. It is a solid foundation
for your professional careers.
PEROVSKITE SOLAR CELLS IN FUTURE TANDEM
It has been talked about for decades that tandem cells
absorbing more of the solar spectrum could yield higher
efficiencies. The development of unique structure
solar cells, like perovskites, should push efficiencies
up closer to the 30s and make panels more realistic
if they can have long functional life and limited
efficiency fading over time.
I will be watching this development.
