odology based on the premise that the computer user’s time and work product are valuable. Experience in the use of interactive systems in a research environment from 1965 to the present time is presented. Current user experience and management of VMI CMS are emphasized. The use of computers as tools for extending users’ powers of memory and logic and the(More)
The performance of Release 4 of TSS/360 at the T. J. Watson Research Center was dramatically improved in the three-month period from November, 1969, through January, 1970. The improvements consist of an increase in system responsiveness by a substantial factor together with an increase in throughput. This was achieved by methodically adjusting the(More)
Immobilized metalloproteins have potential applications in several emerging areas such as bioelectronics and biomimetic energy conversion.1-3 It is well recognized that immobilization of a metalloprotein may affect its electron transfer activity, because of an “incorrect” molecular orientation and/or altered conformation relative to the native state.4-8(More)
We report on the spectroelectrochemical characterization of conducting polymer (CP) films, composed of alternating layers of poly(aniline) (PANI) and poly(acrylic acid) (PAA), deposited on ITO-coated, planar glass substrates using layer-by-layer self-assembly. Absorbance changes associated with voltammetrically induced redox changes in ultrathin films(More)
We report here an investigation of absorbance anisotropy in highly ordered, single bilayer (ca. 5.6 nm) Langmuir-Blodgett (LB) thin films of discotic liquid-crystalline phthalocyanines, using a recently introduced broad-band attenuated total reflectance (ATR) spectroscopic technique, capable of measuring dichroism in such films in the UV--visible optical(More)
We report the first application of a potential-modulated spectroelectrochemical ATR (PM-ATR) instrument utilizing multiple internal reflections at an optically transparent electrode to study the charge-transfer kinetics and electrochromic response of adsorbed films. A sinusoidally modulated potential waveform was applied to an indium-tin oxide (ITO)(More)
Surface-relative orientational parameters were determined for monolayer films of N, N'-ditridecylperylenetetracarboxylic dianhydridediimide (C13-PTCDI) in terms of the relative electronic transition dipole strengths, providing a three-dimensional view of the absorption dipole distribution. In order to obtain a macroscopically ordered film, C13-PTCDI was(More)
