From tectons to luminescent supramolecular ionic liquid crystals.
New phosphorescent and room-temperature liquid-crystalline materials were obtained by combining dicyanometallate anions with dicationic bisamidinium based tectons bearing four peripheral lipophilic pyrogallate moieties.
متن کاملOrganic alloys of room temperature liquids thiophenol and selenophenol.
The first examples of organic alloys of two room temperature liquids, obtained and characterized via in situ cryo-crystallography, are presented. Thiophenol and selenophenol, which exhibit isostructurality and similar modes of S⋯S and Se⋯Se homo-chalcogen interactions along with weak and rare S–H⋯S and Se–H⋯Se hydrogen bonds, are shown to form solid solutions exhibiting Veggard's law-like trends.
متن کاملMolecular tectonics: design of enantiomerically pure helical tubular crystals with controlled channel size and orientation.
The combination of four enantiomerically pure organic tectons composed of a rigid chiral backbone bearing two terminal pyridyl coordinating sites with ZnSiF(6) behaving as an infinite pillar leads to the formation of tubular 2-D enantiomerically pure helical channels with controlled size and orientation.
متن کاملStatic charging of aircraft by collisions with ice crystals
Laboratory experiments measuring the charge transferred when ice crystals collide with various metal targets have shown that the primary influence on the magnitude and sign of the charging is the work function of the metal. The magnitude of the charging of two alloys used for aircraft manufacture varied by a factor of two. Further experiments are needed to characterise the charging of composite...
متن کاملCutting Forces and Tool Wear Investigation for Face Milling of Bimetallic Composite Parts Made of Aluminum and Cast Iron Alloys
Bimetallic parts are used in many industries for weight and cost reduction of workpieces working under high loads and wear. One application for this type of composite material is in automotive industry. In this work the tool wear and cutting forces in the face milling of bimetallic parts made of aluminum and cast iron were investigated. A356 and GG25 alloys that are common materials for bimetal...
