When learning about microscopes decades ago we were taught about
the resolution limits being the diffraction limit.
Super-resolution microscopy observes a static sample multiple times
and modifies the excitation light or changes in the image based on
fluorophore photophysics. A recent review describes improvements
that are helping researchers, clinicians and developers.
It has been a mystery about what forms when pure silicon surfaces
are oxidized. Being able to make Si2O3 and Si2O4 may lead the way
for further developments in microelectronics.
A Wow development of inserting a telescope into a contact lens was
LASERS FOR SUPERRESOLUTION MICROSCOPY
Arrigoni et al describe new laser technologies that are enabling
researchers and clinicians to extend the use of laser microscopes.
The technical depth of the article is clear and articulate so that
other fields will find value in the new developments.
Highlighted in CEN, the report of sub-2 oxides of silicon
synthesis and isolation in Nature Chemistry fills in gap
in the chemical knowledge of subspecies suspected to
be involved doping, protection, carrier generation and capture
layers of microelectronics layers..
TELESCOPIC CONTACT LENS
Trembley and co-workers have fabricated a contact lens which
allows wearers to expand the size of perceived objects
magnifying the view. Still in the prototype phase with
technical issues to overcome, this was in a Photonics
Spectra report of Sarina Tracy.
