A novel series of double hydrogen bonded liquid crystals have been isolated. Hydrogen bond was formed between non mesogen chiral ingredient levo tartaric acid (LTA) and mesogenic undecyloxy benzoic acids (11BA) Thermal and electrical properties exhibited by levo tartaric acid and undecyloxy benzoic acid (LTA+11BA) were discussed. Interesting feature of the present investigation was observation ...

cases frequently occur when one has an opportunity of speedily applying the remedy. A.t first I treated cases by the application of tartaric acid, with a little water, directly to the wound where the poison had been infused. This gave speedy relief in all cases. I next tried the application of alum in the same manner, and found it gave even more speedy relief. A servant of mine was stung in the...

Aromatic oligoamide sequences able to fold into single helical capsules were functionalized with two types of side chains to make them soluble in various solvents such as chloroform, methanol or water and their propensity to recognize tartaric acid was evaluated. The binding affinities to tartaric acid and binding thermodynamics in different media were investigated by variable temperature (1)H ...

This study addressed the possibility of forming of co-amorphous systems between clozapine (CZ) and various carboxylic acid plasticizers (CAPs). The aim was to improve the solubility and oral bioavailability of clozapine. Co-amorphous dispersions were prepared using modified solvent evaporation methodology at drug/plasticizer stoichiometric ratios of 1:1, 1:1.5 and 1:2. Solid state characterizat...
