Structure and function studies of polar mutants of the QA pocket in the bacterial photosynthetic reaction center of Rhodobacter sphaeroides
… contact to the primary quinone (QA), to the polar hydroxyl (O-H) mutants of Ser (M265IS) and Thr (M265IT), previously showed a drop in the in situ Em of QA by 85 and 100 mV, respectively (Takahashi et al 2001). In repeating Takahashi et al’s kinetic work, it was discovered that there are two …

Low Absorption Liquid Crystal Materials for Midwave Infrared
… The fluorine and chlorine not only act as the polar group to provide dipole moment but also helps shift some vibration absorption bands outside the MWIR window. Long phenyl ring compounds, fluorinated tolane materials, and chlorinated terphenyl mixtures are explored; as well as a look as the …

Investigation of structure and permeability of surfaces modified with self-assembled monolayers
… influence the behavior of the interface. Two groups of dialkyl sulfides are prepared and studied: a purely hydrocarbon dialkyl sulfide with the structure CH₃(CH₂)₁₇S(CH₂)<sub>n</sub>CH₃, where n=7, 9, and 17, and a carboxylic acid containing dialkyl sulfide with the structure …

Structure-Activity Studies of Glycosphingolipids as Antigens of Natural Killer T Cells
Glycosphingolipids (GSLs), composed of a polar saccharide head and a lipophilic ceramide tail, are ubiquitous components of the plasma membrane of eukaryotic cells. They serve in many regulatory capacities and have antigenic properties towards natural killer T (NKT) cells of the innate immune …

Electromechanical Characterization of Poly(Dimethyl Siloxane) Based Electroactive Polymers
… are 1) to evaluate the effect of cross-linking polar cyano phenyl (CN) groups on poly (dimethyl siloxane) (PDMS) and 2) to characterize the electromechanical properties of the resulting CN-PDMS blend as an electroactive actuator. Materials responding to an external stimulus are referred to as …
