Bending and first flexural mode vibration behavior of electrostatic actuated nanometer-sized interdigitated cantilever arrays are characterized under vacuum conditions. The "pull-in" effect in dc driving and the "hard spring effect" in ac driving are observed. A mass sensitivity of 20 fg is expected for our devices due to the ultra-small mass of the arm and relative high.. factor. The mass-spring
Radiative lifetime measurements were performed by time-resolved laser-induced fluorescence (LIF) technique for eight even-parity levels of the astrophysically important ion Er+ over the energy range from 33753 to 55317 cm(-1). Free erbium ions were generated by a laser-induced plasma. A narrow bandwidth UV laser pulse (1 ns) was employed to populate selectively the short-lived upper levels, and th
Miniaturization of light-emitting diodes (LEDs) with sizes down to a few micrometers has become a hot topic in both academia and industry due to their attractive applications on self-emissive displays for high-definition televisions, augmented/mixed realities and head-up displays, and also on optogenetics, high-speed light communication, etc. The conventional top-down technology uses dry etching t
Utländska direktinvesteringar i EU skapar arbetstillfällen och för med sig kapital samt expertis från hela världen. Utländska direktinvesteringar är dock inte helt utan risk då de även kan ge upphov till hot mot säkerheten eller allmänna ordningen i unionen. I syfte att hantera dessa risker antogs förordning (EU) 2019/452 av den 19 mars 2019 om upprättande av en ram för granskning av utländska dirForeign direct investments into the EU creates jobs and brings in capital and expertise from all over the world. However, foreign direct investments are not without risks as they can also cause threats to public policy or security in the Union. To mitigate these risks, the EU regulation 2019/452 of 19 March 2019 establishing a framework for the screening of foreign direct investments into the Unio
I och med Hu Jintaos och Wen Jiabaos tillträde till makten har den kinesiska regeringens fokus kommit att flyttas från ren ekonomisk utveckling till att i högre grad än tidigare fokusera på att minska klyftorna mellan stad och landsbygd. Denna uppsats undersöker några av de problem som centralregeringen ser på landsbygden idag, samt några av de lösningar som presenterats. I undersökningen av situa
Along with the interrelation between medical patent right, the generics impacts and the right to access to medicines, which as one of intersection issues between Intellectual Property Rights (IPRs) and Human Rights (HR), has drawn more and more attention under the international society, the Doha Declaration on TRIPS and Public Health has reaffirmed the flexibilities of the Agreement on the Trade R
