Most natural odors are mixtures and often elicit percepts distinct from those elicited by their constituents. This emergence of a unique odor quality has long been attributed to central processing. Here we show that sophisticated integration of olfactory information begins in olfactory receptor neurons (ORNs) in Drosophila. Odor mixtures are encoded in the temporal dynamics as well as in the ma...

In the title complex, [Mn(2)(C(10)H(16)O(4))(C(12)H(8)N(2))(4)(H(2)O)(2)](NO(3))(2)·C(10)H(18)O(4)·2H(2)O, the asymmetric unit contains one-half of the centrosymmetric dinuclear complex cation, one uncoordinated water molecule, one-half of a free sebaic acid (decanedioic acid) molecule that is also completed by inversion symmetry, and one disordered nitrate anion [occupancy ratio 0.454 (4):0.54...

Calix[4]-bis-2,3-naphtho-crown-6 can be used to discriminate between methylammonium and other organic ammonium ions. An electrode based on this ionophore, potassium tetrakis(p-chlorophenyl)borate (20 mol% relative to the ionophore) as an ionic additive and bis(2-ethylhexyl) sebacate as a solvent mediator in a poly(vinyl chloride) membrane matrix, displayed higher selectivity for methylammonium ...

The mol-ecule of the title compound, C(40)H(46)S(2), reveals C(i) symmetry. An inversion centre is located at the mid-point of the C-C bond of the biphenyl unit; the asymmetric unit comprises one-half of the mol-ecule. The conjugated backbone is nearly planar, with a mean deviation of 0.041 Å.

We synthesized and evaluated biodegradable and elastomeric polyesters (poly(glycerol sebacate) (PGS)) using polycondensation between glycerol and sebacic acid to form a cross-linked network structure without using exogenous catalysts. Synthesized materials possess good mechanical properties, elasticity, and surface erosion biodegradation behavior. The tensile strength of the PGS was as high as ...

Poly(glycerol sebacate) (PGS) has increasingly become a desirable biomaterial due to its elastic mechanical properties, biodegradability, and biocompatibility. Here, we report microfibrous core−shell mats of polycaprolactone (PCL)−PGS prepared using wet−wet coaxial electrospinning. The anticoagulant heparin was immobilized onto the surface of these electrospun fiber mats, and they were evaluate...

In the structure of the title salt, 2C(7)H(10)N(+)·C(8)H(2)Cl(2)O(4) (2-)·H(2)O, the two benzyl-aminium anions have different conformations, one being essentially planar and the other having the side chain rotated out of the benzene plane [minimum ring to side-chain C-C-C-N torsion angles = -3.6 (6) and 50.1 (5)°, respectively]. In the 4,5-dichloro-phthalate dianion, the carboxyl-ate groups mak...
