Two different classes of heterogeneous catalysts dominate research and industrial practice of MeOH steam reforming: Pd or Pt on different types of supports and Cu/ZnO systems.[ 1, 5] The commercial Cu/ZnO systems are indeed very active and selective but they require lengthy activation procedures.
Ni et al. [4] research five different classes of solutions: probabilistic schemes, counter-based schemes, distance-based schemes, location-based schemes, and cluster-based schemes for broadcast storm problem.
In order to improve image reconstructions, different classes of nonlinear inversion algorithms are developed and used in different research topics like imaging processes in oil industry or the characterization of complex porous media or multiphase flows.
Ibbotson Associates, a Chicago research firm, has tracked the performance of different classes of stocks over time.
At the same time, toxicological research has led to a growing awareness that different classes of PCB congeners have different profiles of toxicity.
Importantly, this research provided new targets for pain treatment, and different classes of compounds that are effective against pain in animal models and that are now being tested in humans in different phases of clinical trials have emerged.
Under such circumstances, it would seem naive to invest research efforts into in vitro gene expression profiling studies aimed at classifying different classes of hepatotoxic compounds.
A general strategy employed by many research groups in fulfilling these requirements is based on coating the nanoparticles with different classes of biopolymers.
In our latest research, we construct a publicly available database of government debt holdings by six different classes of investors.
Research is needed to characterize the nature and extent of the inhalant abuse for different classes of abused inhalants in relevant population subgroups.
