Researchers monitor electron behavior during chemical reactions for the first time
In a recent publication in Science, researchers at the University of Paderborn and the Fritz Haber Institute Berlin demonstrated their ability to observe electrons' movements during a chemical reaction. Researchers have long ...
What really happens at femtosecond junctions?
When beams of ultra-short laser pulses running in the same direction intersect with each other at a noticeable angle, various interactions occur between the pulses. These physical phenomena are complicated, and their mathematical ...
A major step toward non-viral ocular gene therapy using laser and nanotechnology
In January 2009, the life of engineer Michel Meunier, a professor at Polytechnique Montréal, changed dramatically. Like others, he had observed that the extremely short pulse of a femtosecond laser could make nanometre-sized ...
Directivity to improve optical devices
A team of researchers from the Dutch institute AMOLF, Western University (Canada), and the University of Texas (United States of America) recently demonstrated the use of algorithmic design to create a new type of nanophotonic ...
World's fastest camera freezes time at 10 trillion frames per second
What happens when a new technology is so precise that it operates on a scale beyond our characterization capabilities? For example, the lasers used at INRS produce ultrashort pulses in the femtosecond range (10-15 s), which ...
Nobel-winning physics key to ultra-fast laser research
The technique for generating high-intensity, ultra-short optical pulses developed by the 2018 Nobel Prize for Physics winners, Professor Gérard Mourou and Dr. Donna Strickland, provides the basis for important scientific ...
Transition metal dichalcogenides could increase computer speed, memory
Transition metal dichalcogenides (TMDCs) possess optical properties that could be used to make computers run a million times faster and store information a million times more energy-efficiently, according to a study led by ...
Reaction of a quantum fluid to photoexcitation of dissolved particles observed for the first time
In his research, Markus Koch, Associate Professor at the Institute of Experimental Physics of Graz University of Technology (TU Graz), concentrates on processes in molecules and clusters which take place on time scales of ...
Study demonstrates new mechanism for developing electronic devices
The prevalence of electronic devices has transformed life in the 21st century. At the heart of these devices is the movement of electrons across materials. Scientists today continue to discover new ways to manipulate and ...
