Applied Physics Letters is a peer-reviewed scientific journal that is published 52 times per year by the American Institute of Physics. Its focus is rapid publication and dissemination of new experimental and theoretical papers regarding applications of physics in all disciplines of science, engineering, and modern technology. Additionally, there is an emphasis on fundamental and decisive new developments which lay the groundwork for fields that are rapidly evolving. The journal was established in 1962. The editor in chief is Nghi Q. Lam of the Argonne National Laboratory. According to the Journal Citation Reports, the journal has a 2010 impact factor of 3.820, ranking it first out of 105 in the discipline of applied physics. In 2009, it also ranked first out of 105 journals assessed in this discipline.
'Reverse engineering' materials for more efficient heating and cooling
If you've ever gone for a spin in a luxury car and felt your back being warmed or cooled by a seat-based climate control system, then you've likely experienced the benefits of a class of materials called thermoelectrics. ...
Building a more versatile frequency comb
Frequency combs are the rulers of light. By counting a wavelength's many oscillations, they measure distance and time with extraordinary precision and speed.
