Photoalignment at the nematic liquid crystal - polymer interface: experimental evidence of three-dimensional reorientation
We provide experimental evidence that photoalignment at the nematic liquid
crystal (NLC) - polymer interface can not be simply considered as a
two-dimensional process. Moreover, our experiments clearly indicate that the
photoaligning process does not depend on the individual properties of the NLC
material and those of the interfacing polymer exclusively. According to our
measurements, the polymer and the NLC layer "sense-each-other", i.e., the
polymer-liquid crystal interface should be regarded as a coupled system, where
the two components mutually influence each other. Furthermore, we show that the
temperature induced anchoring transition also has to be taken into account for
the complete description of the photoalignment mechanism.Comment: 20 pages, 8 figures, submitte
Az elektromos hajtásé a jövő? : mikor, hol, hogyan és mennyiért?
Az a meglátásom, hogy sajnos elĂ©g sok elfogult, valamely szempontbĂłl prekoncepciĂłs „elemzĂ©s” lĂ©tezik Ă©s szĂĽletik a tĂ©mában, melyek számĂtásában jelentĹ‘s hiányosságokra utalĂł eredmĂ©nyek is szerepelnek.

Abstract: My view is that, unfortunately, there are a lot of biased, somewhat preconceptual “analyzes” exist and are born on the subject electric vehicle.

It is more convenient and unfortunately, in many cases seems to be sufficient, to use a well-known, or often used, trendy reference instead of meaningful critical evaluation and thought.

Szeged közösségi közlekedésének jövője elektromos meghajtású járművek használatával az ELIPTIC projekt tapasztalatai alapján
In our urbanizing world has always been an important task the design and implementation of an efficient, economical, sustainable local transport system. Under the sustainability Today, almost everyone understands the environmentally friendly use of energy-efficient solutions, which are alternatives to private transport electric public transport, cycling, walking, car-sharing and e-car was driving the generally accepted approach. Due to increasing population and changes of lifestyle, expands the number of individual trips and ever more complex to offer a solution that meets the man of our time. In Szeged, the settlement structure, the built transport infrastructure, the track-developed network, all suggest the expansion of the use of electric vehicles. The possibility of penetration of electric vehicles examines in two directions the H2020’s ELIPTIC project funded by the European Union. One of the directions is the expansion, extension of trolleybus lines without the overhead construction reducing the rate by coach and bus services. The other direction to build a multifunctional electric charger network based on the existing infrastructure.VárosiasodĂł világunkban mindig fontos feladat volt a helyi közlekedĂ©s hatĂ©kony, gazdaságos, fenntarthatĂł kialakĂtása, megvalĂłsĂtása. A fenntarthatĂłság alatt napjainkban szinte mindenki a környezetbarát, energiahatĂ©kony megoldások alkalmazását Ă©rti, ami általánosan elfogadott szemlĂ©letben az egyĂ©ni közlekedĂ©st kiváltĂł elektromos hajtásĂş közössĂ©gi közlekedĂ©st, kerĂ©kpározást, gyaloglást, carsharing-et Ă©s e-autĂłzást jelent. A lakosság számával Ă©s Ă©letmĂłdjának változásával bĹ‘vĂĽlĹ‘ egyĂ©ni utazások száma miatt egyre bonyolultabb olyan megoldást ajánlani, ami korunk emberĂ©nek megfelel. Szegeden, a telepĂĽlĂ©sszerkezet, az Ă©pĂtett közlekedĂ©si infrastruktĂşra, a kialakult kötöttpályás hálĂłzat, mind sugallja az elektromos meghajtásĂş járművek használatának bĹ‘vĂtĂ©sĂ©t. Az elektromos jármĂĽvek tĂ©rhĂłdĂtásának lehetĹ‘sĂ©gĂ©t kĂ©t irányban vizsgálja az EurĂłpai UniĂł által támogatott H2020-as ELIPTIC projekt. Az egyik irány a trolibusz vonalak bĹ‘vĂtĂ©se, meghosszabbĂtása felsĹ‘vezetĂ©k Ă©pĂtĂ©se nĂ©lkĂĽl, az autĂłbusszal vĂ©gzett szolgáltatási arány kárára. A másik irány a meglĂ©vĹ‘ infrastruktĂşrára Ă©pĂĽlĹ‘ multifunkcionális elektromos töltĹ‘ hálĂłzat kiĂ©pĂtĂ©se
