“…When exposed to H 2 gas, Pd absorbs H 2 to form PdH x with x = 0.6 for 0.1 atm < H 2 pressure < 1 atm. 11,21,22 As expected, at V D = 0 V, I D for a solution with a low proton concentration (e.g., pH 11) is larger than I D from a solution with a high proton concentration (e.g., pH 2), and no depletion occurs at pH 0 because µ pH=0 = µ PdH . This is because an increase in proton concentration at the protode surface results in a smaller protochemical potential difference between the loaded PdH x contact and the solution.…”

Translating ionic currents into measureable electronic signals is essential for the integration of bioelectronic devices with biological systems. We demonstrate the use of a Pd/PdHx electrode as a bioprotonic transducer that connects H+ currents in solution into an electronic signal. This transducer exploits the reversible formation of PdHx in solution according to PdH↔Pd + H+ + e−, and the dependence of this formation on solution pH and applied potential. We integrate the protonic transducer with glucose dehydrogenase as an enzymatic and gate for glucose and NAD+. PdHx formation and associated electronic current monitors the output drop in pH, thus transducing a biological function into a measurable electronic output.

“…This type of representation [12] is useful in that it emphasises that, in this condensed type of complex, interaction between the chemically reactive components, X and Y, and the processes of ligand conduction across the complex in the osmotic barrier, require specific proximity of the reactive components, and probably also some specifically articulated conformational movements within the complex. Such conformational mobility is obviously less likely to be required for electron conduction [59-661 and proton conduction [67] than for the conduction of other types of ligand, such as hydrogen atoms carried by ubiquinol [68], or, as may be required in the protonmotive ATPase, 0'-groups carried by the circulation of adenine nucleotides and inorganic phosphate [Eqn (9)] [12]. Returning to the chemiosmotically coupled oxidative and photosynthetic phosphorylation systems represented by Fig.…”

Chemical reactions, like osmotic reactions, are transport processes when looked at in detail. Chemical catalysis by enzymes or catalytic carriers, and osmotic catalysis by porters, may be conceived as occurring by specific ligand‐conduction mechanisms. In chemiosmotic reaction systems, the pathways of specific ligand conduction are spatially orientated through anisotropic enzyme and catalytic carrier complexes in which the reactions of chemical group transfer occur as vectorial diffusion processes of group translocation down gradients of group potential that represent real spatially‐directed fields of chemical force. Thus, it is easier to explain biochemistry in terms of transport than it is to explain transport in terms of biochemistry.

Ammonium dihydrogen Phosphate (ADP), crystals are good Second Harmonic Generators (SHG) having appreciable Non Linear Optical properties. Single crystals of ammonium dihydrogen phosphate were grown using slow evaporation technique at 30° C. In order to study of ADP, X-ray diffraction studies were carried out on the crystals using Bruker AXS D8 Advance X-ray diffractometer with Cu K radiation. The grown single crystals have been analyzed with FT-IR, TGA measurements. Some novel results of a combined sequential study of growth spirals on the basal surface of the richly polytypic ADP crystals by scanning electron microscopy (SEM) is presented and discussed.
