The distribution of CO2 and the associated carbonic acid system species in the upper ocean (here loosely defined as waters above the thermocline and generally only a few hundred meters in depth) is primarily controlled by the exchange of CO2 across the air-sea interface, biological activity, and circulation of the ocean, mainly through vertical mixing processes. Other factors, such as the temperature and salinity of the water, can also contribute to variations by influencing the solubility of CO2 in seawater and the equilibrium constants of the carbonic acid system. 

Abstract To appreciate the technological potential of controlled molecular-level motion one only has to consider that it lies at the heart of virtually every biological process. When we learn how to build synthetic molecular motors and machines that can interface their effects directly with other molecular-level sub-structures and the outside world it will add a new dimension to functional molecule and materials design. In this review we discuss both the influence of chirality on the design of molecular level machines and, in turn, how molecular level machines can control the expression of chirality of a physical response to an inherently achiral stimulus. 

As discussed previously, different interactions between molecules, solvent, and substrate play an important role in two-dimensional crystal engineering. Another key factor which can strongly influence the outcome of the self-assembly process is chiralityThis structural aspect also assumes immense importance within a broad range of research domains such as catalysis and materials science. Separation of enantiomers is still a main concern in the pharmaceutical industry and the study of chirality on surfaces could be of great potential in this field. STM has been considered as an ideal technique to investigate the expression of chirality at a variety of interfaces with sub-molecular resolution.We focus on ambient conditions since it resembles the environment in which many important chemical and biological processes take place. 

Specific DNA-protein interactions which either promote or inhibit CT processes through the protein-DNA interface would be the most crucial part of a biological system sensing DNA damage. Recent experiments have shown clearly that DNA-mediated CT processes are modulated both negatively and positively by DNA-binding proteins. Most importantly, each of the observed influences of the proteins can be explained by special structural features of the corresponding DNA-protein complexes. Thus, special DNA-protein interactions result in a characteristic modulation of the DNA-mediated CT. 

Furthermore, abiotic and biotic reactions are not independent but rather, interactive processes in soil environments. Interactions of abiotic and biotic processes are thus very important in governing the dynamics and fate of metals and metalloids in soils, especially at the soil-root interface. Abiotic and biotic interactions in the rhizosphere in influencing the stabilization of contaminants and the efficacy of ameliorants need to be investigated. The impact of physical, chemical, and biological interfacial interactions on risk assessment and management of metal and metalloid contamination and restoration of ecosystem health merits close attention.
