Quantum chemistry software that exploits the capabilities of modern GPUs has only recently started to emerge. Significant parts of these initial efforts have been devoted to minimize errors caused by the lack of DP support on older GPUs. The advent of next-generation GPUs that support DP arithmetics at a peak performance of only a factor of 2 less than that of SP will make these special approaches obsolete. At the same time, future developments will be greatly facilitated. 

Microbial degradation of nitrile compounds was performed by different microorganisms, capable of growing on various aliphatic and aromatic nitriles [107-109], They are degraded through two pathways (Figure 7) one is the direct hydrolysis of nitriles to carboxylic acid and ammonia, catalyzed by nitrilases. Nitrilases, that utilize benzonitrile and related aromatic nitriles as substrates, have been purified from Pseudomonas sp. [110.111], Nocardia sp. strains NCIB 11215 [112] and NCIB 11216... 

Besides the cocatalyst, there are some other additives that are capable of influencing the performance of catalyst systems during styrene polymerization. The addition of a proper amount of triisobutylalu-minum (TIBA) to various titanium complex/MAO systems increases the catalyst activity, whereas the addition of TMA or triethylaluminum (TEA) inhibits polymerization. A relatively high molar ratio of TIBA/MAO will cause a reduction in activity and a sharp decrease in the molecular weights of sPS. When a haloalkylaluminum such as AlEt2Cl is used with the CpTiCb/MAO system, only atactic polystyrene is produced by a noncoordination polymerization process, that is, a cationic... 

The low electric power loss inherent in the SPS structure, combined with the capability to easily fill thin walled, complex tools, has resulted in significant growth of SPS into electronic components such as embedded antennas and various interconnect devices that rely on consistent electrical performance.
