“Cosmologists believe that only about 20% of the total matter is made of regular or ‘baryonic’ matter, which includes stars, galaxies, atoms, and life,” explains first author Dr. Mohamed Abdullah, a researcher at the National Research Institute of Astronomy and Geophysics-...
found in this "hot Saturn." Because WASP-39b has so much more water than our famously ringed neighbor, it must have formed differently. The amount of water suggests that the planet actually developed far away from the star, where it was bombarded by a lot of icy material. WASP-39b likely...
Moving one step further, attosecond pulses (10-18 seconds) are fast enough to study the movement of electrons around atoms; they are a billion billionths of a second in duration, which is to a second what a second is to the age of the Universe. Ultrafast laser systems available commerciall...
Which element has the same number of valence electrons as nitrogen (N) in the periodic table? a. carbon (C) b. phosphorus (P) c. neon (Ne) d. oxygen (O) What are elements and atoms? Select the correct answer. Which of the fol...
the optical meta-atom can trap a bit of light for a time limited only by imperfections in the materials. To compensate for this inevitable loss, the researchers suggest using anoptical gainelement, like a weaker version of the gain used in lasers. This addition would also enable the meta-at...
The disordered materials of the '597 patent were designed to have unusual electronic configurations, which resulted from the varying 3-dimensional interactions of constituent atoms and their various orbitals. The disorder came from compositional, positional and translational relationships of atoms. Selected...
