This work presents a model for the inclusion of chemical water stability in optimizing the operation of water distribution systems. When desalinated water is mixed with surface water and/or groundwater, the blend can become chemically unstable. Such a state can cause the phenomena of “red water,” an increase in corrosion rates, and a reduction in disinfection efficiency. In this study, a method...

This document summarizes the large program of chemical research and development which led to selection of fuel and coolant compositions for the Molten-Salt Reactor Experiment (MSRE) and for subsequent reactors of this type. Chemical behavior of the LiF-BeFrZrFrUF4 fuel mixture and behavior of fission products during power operation of MSRE are presented. A discussion of the chemical reactions w...

Artificial nanowalkers are inspired by biomolecular counterparts from living cells, but remain far from comparable to the latter in design principles. The walkers reported to date mostly rely on chemical mechanisms to gain a direction; they all produce chemical wastes. Here we report a light-powered DNA bipedal walker based on a design principle derived from cellular walkers. The walker has two...

In this paper, we first collect the earlier results about some graph operations and then we present applications of these results in working with chemical graphs.

In this paper, some applications of our earlier results in working with chemical graphs are presented.

Stemming from MEMS (MicroElectroMechanical System) developments, designs and fabrication technology, packaged microfluidic chips – used first for biological and chemical analysis (μTAS, Micro Total Analysis Systems) – were modified to perform chemical syntheses (1). In addition, chip devices for the mixing of miscible or immiscible fluids offered a novel means for the processing of this unit op...

the continuous improvement of eaf performance is crucial for the increase in productivity and cost effectiveness and to render an environmental friendly process. rhi supports these targets by providing a diverse range of refractory and process solutions. chemical energy in practical operation by injection of gaseous media like oxygen and natural gas, and solid materials like carbon have become ...
