TL;DR: In this paper, a spray printing technique was used to fabricate large-area flexible electrodes using poly (3, 4-ethylene dioxythiophene)-polystyrene sulfonate (PEDOT:PSS) and polyester cloth.
Abstract: We report on a one-step spray printing technique to fabricate large-area flexible electrodes using poly (3, 4-ethylene dioxythiophene)-polystyrene sulfonate (PEDOT:PSS) and polyester cloth. The H3PO4 treated PEDOT:PSS electrodes exhibit an enhanced capacitance, high rate capability and wide voltage window (0–1.6 V). The printed polyester/PEDOT:PSS electrode treated with H3PO4 exhibits a specific capacitance of ∼40 F g−1 at 40 mV s−1. A large area device exhibits a high iR drop of 0.23 V, which can be minimized using conducting materials such as carbon cloth or steel mesh in place of polyester cloth.

TL;DR: In this paper, the modified Adler's method and its X-ray crystal structure solved was applied to 5, 10, 15, 20, 20-tetrakis-(4-chlorophenyl) porphyrin, H2TTPCl4.
Abstract: Abstract 5, 10, 15, 20-tetrakis-(4-chlorophenyl) porphyrin, H2TTPCl4, has been isolated as a new polymorph following the modified Adler’s method and its X-ray crystal structure solved. The new polymorph (I) crystallises in the monoclinic space group, P21/n with a = 10.1574(5) Å, b = 8.9827(4) Å, c = 20.9350(8) Å, β = 102.532(4)°, V = 1864.62(15) Å3, Z = 2. The previously found polymorph, prepared using Lindsay method was crystallised in monoclinic space group, P21/a with a = 15.776 (13) Å, b = 8.646 (3) Å, c = 14.087 (5) Å, β = 96.05 (5)°, V = 1910.7 (3) Å3, Z = 2. The main difference between the two polymorphs seems to be the different packing arrangement of molecules in their crystal lattices. The dramatic self aggregation property of new polymorph (I) has also been investigated. The investigation reveals that under certain conditions of solute concentration and pH of the media, the compound exhibits a strong tendency to exist in a prominent self aggregated state in head-to-tail type (j-aggregation) molecular alignment. The self association behaviour of (I) was confirmed by UV-Vis absorption spectra, performed in chloroform by varying concentrations and pH changes and 1H NMR spectra, performed in deuterated chloroform at varying concentrations and their results have been discussed in detail.
