Rotational analysis of the 000-000 and 010-000 bands of SiC2

Journal of Molecular Spectroscopy, 1988
Abstract High-resolution absorption spectra of SiC 2 have been observed in a flash discharge through Si(CH 3 ) 2 and helium. The two strongest bands at 4977 and 4867 A have been fully analyzed. The rotational constants derived accurately predict the observed interstellar lines.

An Aqueous Zn‐Ion Hybrid Supercapacitor with High Energy Density and Ultrastability up to 80 000 Cycles

Advanced Energy Materials, 2019
Integrating a battery‐type electrode to build a hybrid supercapacitor is a promising approach to improve the overall energy density of a supercapacitor‐type energy storage device without sacrificing its power output.

Physics: The Next 1 000 000 000 000 000 000 000 000 000 000 Years

Physics Bulletin, 1982
I am sure we all feel that in some sense or other there lies behind our experience of the natural world, as physicists, chemists, geologists and so on, some kind of unity, some kind of unifying principle, to which all natural phenomena lead back or from which, equivalently, all natural phenomena may be derived. I also suspect that some of us would wish

Stable Seawater Electrolysis Over 10 000 H via Chemical Fixation of Sulfate on NiFeBa‐LDH

Advances in Materials
Although hydrogen production through seawater electrolysis combined with offshore renewable energy can significantly reduce the cost, the corrosive anions in seawater strictly limit the commercialization of direct seawater electrolysis technology.

Up to 650 000 people die of respiratory diseases linked to seasonal flu each year

Saudi Medical Journal, 2018
This marks an increase on the previous global estimate of 250 000 – 500 000, which dates from over ten years ago and covered all influenza-related deaths, including cardiovascular disease or diabetes. The new figures of 290 000 – 650 000 deaths are based

On the perturbations in the (000-000) band of the BaOH - transition

Journal of Molecular Spectroscopy, 1991
Abstract A laser-spectroscopic investigation of the (000-000) band of the B 2 Σ + - X 2 Σ + transition of the BaOH molecule has been performed. The analysis shows that the upper level is badly perturbed, presumably by a Σ vibronic level of the A 2 Π 3 2 state.

Planetary elements for 10 000 000 years

Celestial Mechanics, 1973
In 1950 Brouwer and van Woerkom published a secular theory of the variations of the planetary elements in analytical form. In the present paper we provide a graphical representation of this theory in the form of element plots for a time span of ten million years.
