Journal Article
Halls, J. E., & Wadhawan, J. D. (2012). Photogalvanic cells based on lyotropic nanosystems: towards the use of liquid nanotechnology for personalised energy sources. Energy & environmental science, 5(4), 6541-6551. doi:10.1039/c2ee03169h

A lightweight, autonomous and practical, proof-of-concept electrical power source is developed within this work. It comprises a photoredox-active material embedded within the non-ionic surfactant subphase, with a second redox reagent present within t... Read More

A photogalvanic cell that employs 2,4-dichlorophenol as a fuel source, an N-substituted phenothiazine as light harvester, and sacrificial zinc anode is presented, and shown to afford a ca. 4% light-to-electrical power conversion efficiency in violet... Read More

Voltammetry within structured liquid nanosystems: towards the design of a flexible, three-dimensional framework for artificial photosystems (2012)
Journal Article
Halls, J. E., Wright, K. J., Pickersgill, J. E., Smith, J. P., Altalhi, A. A., Bourne, R. W., …Wadhawan, J. (2012). Voltammetry within structured liquid nanosystems: towards the design of a flexible, three-dimensional framework for artificial photosystems. Electrochimica acta, 70, 215-227. https://doi.org/10.1016/j.electacta.2012.03.052

Normal lyotropic liquid crystals (in the lamellar or hexagonal phases) are investigated as a route to afford a structured, three-dimensional, quasi-biphasic framework within which electron transfer cascades may be initiated voltammetrically. For mode... Read More

Two aqueous lyotropic chromonic liquid crystals made from nickel(II) or copper(II) phthalocyananine tetrasulfonic acid tetrasodium salt are prepared with characterisation through optical polarising microscopy, X-ray diffraction and conductivity. Thes... Read More

Concentration-dependent diffusion coefficients of tert-butylferrocene within dodecyltrimethylammonium chloride/brine liquid crystals (2012)
Journal Article
Halls, J. E., Altalhi, A. A., De Abreu, F. C., Goulart, M. O., & Wadhawan, J. D. (2012). Concentration-dependent diffusion coefficients of tert-butylferrocene within dodecyltrimethylammonium chloride/brine liquid crystals. Electrochemistry communications, 17, (41-44). doi:10.1016/j.elecom.2012.01.013. ISSN 1388-2481

The title lyotropic liquid crystal is examined as a framework to investigate long-range charge transfer, using tert-butylferrocene (tBuFc) as model hydrophobic system. It is found that the apparent one-dimensional diffusion coefficient depends on the... Read More
