New liquid-crystalline pillar[5]arene derivatives have been prepared by grafting first-generation Percec-type poly(benzylether) dendrons onto the macrocyclic scaffold. The molecules adopt a disc-shaped structure perfectly suited for self-organization into a columnar liquid-crystalline phase. In this way, the pillar[5]arene cores are piled up, thus forming a nanotubular wire encased within a she...
A mobile site level data collection system has been implemented for piling works utilising the IEEE 802.11b wireless protocol. The system, used by dedicated ‘pile managers’ and the workforce, allows for realtime data collection and storage into a site-based server, via a mobile wireless local area network (WLAN). The use of a WLAN allows for easy access and manipulation of timely construction d...
