New tail-to-tail twins with alkyl or perfluorinated spacers were synthesized. The mesomorphic properties were studied by polarizing microscopy and X-ray diffraction measurements. It was found that the smectic C phase is a S C2 phase with alternating

We synthesized swallow-tailed compounds, A and B, containing fluorinated alkyl chains in different terminal positions and dipoles in opposite directions. An increase of the clearing points and a stabilization of the smectic phases compared to the non

New benzoyloxybenzoic acids bearing both terminal and lateral groups have been synthesized. Substituted aryl rings are laterally attached to the basic mesogens by means of an odd-numbered spacer. Therefore, liquid crystalline behaviour can be observe

Perfluorinated alkyl chains were introduced into proton donating molecules which are able to form hydrogen bonded associates with suitable proton acceptors. Mesophase induction and stabilization were observed. Liquid crystalline associates were prove

The responses of diesel engine exhaust emissions to transients in speed and torque are examined. Particulate matter, hydrocarbons, carbon monoxide, and oxides of nitrogen were sampled for discrete segments of various transient cycles. Each cycle cons

Diesel exhaust levels have been measured during discrete transients in speed and load, and with changes made to the engine and fuel. Particulate, oxides of nitrogen, unburned hydrocarbon, and carbon monoxide measurements were made for two fuels, DF2
