Solar activity and solar flux oscillations
Izvestiya VUZ. Applied Nonlinear Dynamics, 1997 The conditions of full orbit solar flux observation by Solar Constant Monitor (SCM-2) from «Meteor—3» № 7 satellite in February 1995 are described. The power spectra of such daily measurement series of 108 min. duration during two weeks are obtained. The total solar flux oscillations (not registered earlier) with periods range 6-15 min.

Positive‐Tone Nanolithography of Antimony Trisulfide with Femtosecond Laser Wet‐Etching
Advanced Functional Materials, EarlyView.A butyldithiocarbamic acid (BDCA) etchant is used to fabricate various micro‐ and nanoscale structures on amorphous antimony trisulfide (a‐Sb2S3) thin film via femtosecond laser etching. Numerical analysis and experimental results elucidate the patterning mechanism on gold (reflective) and quartz (transmissive) substrates.

Variation of D-region nitric-oxide density with solar activity and season at the dip equator [PDF]
To study the solar control on electron density (N sub e) in the equatorial D region, a program was initiated with Soviet collaboration in 1979. A total of 31 rockets were launched during the high solar activity period, and 47 rockets during the low solar

Advanced Functional Materials, EarlyView.Glyphosate (GLY) and its primary metabolite, aminomethylphosphonic acid (AMPA), are photodegraded using a poly(vinylidene fluoride) membrane with immobilized titanium dioxide (PVDF‐TiO2) in a continuous flow‐through operation under solar light. At optimized conditions, the PVDF‐TiO2 membrane achieved 95% GLY and 80% AMPA removal with •O2− as the ...

Ionospheric effects of the extreme solar activity of February 1986 [PDF]
During February 1986, near the minimum of the 11 year Solar sunspot cycle, after a long period of totally quiet solar activity (R sub z = 0 on most days in January) a period of a suddenly enhanced solar activity occurred in the minimum between solar ...
