Phys.org / Novel method enhances size-controlled production of luminescent quantum dots

Luminescence refers to the result of a process in which an object absorbs light at one wavelength and then re-emits it at another wavelength. Through light absorption, electrons in the ground state of the material are excited ...

Phys.org / New study shows mysterious solar particle blasts can devastate the ozone layer, bathing Earth in radiation for years

The remarkable aurora in early May this year demonstrated the power that solar storms can emit as radiation, but occasionally the sun does something far more destructive. Known as "solar particle events," these blasts of ...

Phys.org / Treatment with a mixture of antimicrobial peptides found to impede antibiotic resistance

A common infection-causing bacteria was much less likely to evolve antibiotic resistance when treated with a mixture of antimicrobial peptides rather than a single peptide, making these mixtures a viable strategy for developing ...
