Federated remote laboratory management system, REMLABNET III, (version 2016), for the integrating and management of remote experiments for starting university level and secondary schools, is presented. Its building was initiated both from the extensive use and expertise in Internet School Experimental System (ISES) and the lack of a similar system for remote experiments building for starting university level and secondary schools in Europe. The system uses new features, compared to REMLABNET II (version 2015) we intend to present: -federation of two RLMS systems Go-Lab and Remlabnet into one cooperating system sharing remote experiments, new Measureserver with advanced diagnostics of connected experiments, and log files for individual connections of clients and their evaluation.

Low stability and degradability of polymers by ambient air, UV irradiation or charge transport are major problems of molecular electronics devices. Recent research tentatively suggests that the presence of a crystalline phase may increase polymer stability due to an intensive energy trapping in the ordered phase. Using the UV degradability, we demonstrate this effect on an archetypal model σ bonded polymer - poly[methyl(phenyl)silane] (PMPSi) - with partially crystalline and amorphous-like layers. UV degradation with 345 nm, derived from the branching state generation rate, was inversely proportional to the crystalline phase content, changing from 4.8x1011 s-1 (partially crystalline phase) to 1.8x1013 s-1 (amorphous-like phase). A model is proposed where crystallites formed by molecular packing act as effective excitation energy traps with a suppressed nonradiative recombination improving thus PMPSi film stability. The molecular packing and higher crystalline phase proportion may be a general approach for stability and degradability improvement of polymers in molecular electronics.

Abstract-The development of new informationtechnologies is enabling remote experimentation, a common practice in university education. This contribution describes the procedure of developing the remote experiment-the Archimedes´ Principle-using the Internet School Experimental System (ISES) for hands on experimentation and Easy Remote ISES software for transformation of this experiment to a remote one, applied for the first time. The experiment consists of the mobile platform with controlled and measured displacement, on which were placed three vessels with liquids. The bodies were suspended from the ISES dynamometers, measuring the resulting suspension force when they were dipped into liquid. The simultaneous measurement of the suspension force enabled recording of the weight, total force or buoyancy force alone. The experiment is available on http://remotelab9.truni.sk as a part of e-laboratory in Trnava, Slovakia (http://kf.truni.sk/remotelab).
