TL;DR: In this paper, two types of the charge injection mechanisms may be distinguished, in the first, charge is transferred from the excited state of the sensitizer molecule to the conduction or valence band while the second mechanism involves a direct molecule-to-band charge transfer (MBCT).

TL;DR: Under these conditions, simultaneous irradiation with UV and visible light results in compensation of anodic and cathodic photocurrents, and zero net photocurrent is observed, which can be used for construction of unique light-driven chemical logic gates.
Abstract: Photoelectrodes made of nanocrystalline titanium dioxide modified with various pentacyanoferrates exhibit unique photoelectrochemical properties; photocurrent direction can be switched from anodic to cathodic and vice versa upon changes in photoelectrode potential and incident light wavelength (PhotoElectrochemical Photocurrent Switching, PEPS effect). At certain potentials, anodic photocurrent generated upon UV irradiation has the same intensity as the cathodic photocurrent generated upon visible irradiation. Under these conditions, simultaneous irradiation with UV and visible light results in compensation of anodic and cathodic photocurrents, and zero net photocurrent is observed. This process can be used for construction of unique light-driven chemical logic gates.

TL;DR: New aspects of reactivity of two pentacyanoferrates are presented, found that the reaction enthalpies and entropies depend strongly on the cation radius and the reaction volume is strongly affected by the structure and properties of the hydration shell.
Abstract: The article presents new as- pects of reactivity of two pentacyano- ferrates: (Fe(CN)5NO) 2� and (Fe(CN)5- N(O)SR) 3� . The dependence of ther- modynamic functions on cations was found for the reaction between nitro- prusside and thiolate. The thermody- namic data are interpreted in terms of ion pairing and changes in the solva- tion shell of the cations. It was found that the reaction enthalpies and entro- pies depend strongly on the cation radius. The reaction volume in turn is strongly affected by the structure and properties of the hydration shell. Care- ful data analysis allowed the contribu- tion of partial cation dehydration to the total reaction volume to be deter- mined. The experimental results were also interpreted in terms of chemical logic gates. Complex logic systems were built from a number of cells con- taining a switching compound arranged in different geometric patterns. Increas- ing the dimensionality of these ar- rangements leads to really complex logic systems containing up to 20 AND and OR logic gates. The system is ca- pable of processing up to 16 bits of input data.

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality. Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …
