متن کاملStudies in the Organic Solid State
This paper describes an approach to crystal engineering based on designing and analyzing hierarchical levels of crystal l ine architecture. The system under study consists of 1:1 co-crystals of melamines and barbituric acids that selfassemble into crystallographically infinite hydrogen-bonded tapes. The formation of structural elements can be rat ional ized and control led using famil iar molec...
متن کاملMethanol synthesis catalyst manufacturing using the green solid-state method
In this research study, methanol synthesis catalysts were manufactured with various mole ratios of metal carbonates (zinc, copper and aluminum carbonate) and ammonium hydrogen carbonate via a green solid-state method that employed a ball mill apparatus. Some parameters for the catalyst preparation, such as Al mole percent, Cu/Zn mole ratio, rotations milling speeds and aging time, were optimize...
متن کاملSolid-state dimer method for calculating solid-solid phase transitions.
The dimer method is a minimum mode following algorithm for finding saddle points on a potential energy surface of atomic systems. Here, the dimer method is extended to include the cell degrees of freedom for periodic solid-state systems. Using this method, reaction pathways of solid-solid phase transitions can be determined without having to specify the final state structure or reaction mechani...
متن کاملThe Stability Studies of Penicillin and Ampicillin following ?-Irradiation in the Solid State
The effect of 10 and 25 kGy ?-irradiation on penicillin G plus procaine and sodium ampicillin has been assessed by different chemical and microbiological analytical methods. According to the chemical results obtained, the antibiotics showed a slight reduction in doses applied but the microbiological assays revealed that the activity of irradiated antibiotics did not reduce. Microbiological stud...
