does a cyclopropane ring enhance the Electronic Communication in dumbbell type c60 dimers
Journal of Organic Chemistry, 2014Co-Authors: Andrea La Rosa, Katalin Gillemot, Edmund Leary, Charalambos Evangeli, Maria Teresa Gonzalez, Salvatore Filippone, Gabino Rubiobollinger, Nicolas Agrait, Colin J Lambert, Nazario MartinAbstract:Two C60 dumbbell molecules have been synthesized containing either cyclopropane or pyrrolidine rings connecting two fullerenes to a central fluorene core. A combination of spectroscopic techniques reveals that the cyclopropane dumbbell possesses better Electronic Communication between the fullerenes and the fluorene. This observation is underpinned by DFT transport calculations, which show that the cyclopropane dumbbell gives a higher calculated single-molecule conductance, a result of an energetically lower-lying LUMO level that extends deeper into the backbone. This strengthens the idea that cyclopropane behaves as a quasi-double bond.

tetrathiafulvalene based nanotweezers noncovalent binding of carbon nanotubes in aqueous media with charge transfer implications
Journal of the American Chemical Society, 2012Co-Authors: Carlos Romeronieto, Raul Garcia, Angeles M Herranz, Christian Ehli, Michaela Ruppert, Andreas Hirsch, Dirk M Guldi, Nazario MartinAbstract:Electron donor–acceptor hybrids based on single wall carbon nanotubes (SWCNT) are one of the most promising functional structures that are currently developed in the emerging areas of energy conversion schemes and molecular Electronics. As a suitable electron donor, π-extended tetrathiafulvalene (exTTF) stands out owing to its recognition of SWCNT through π–π stacking and electron donor–acceptor interactions. Herein, we explore the shape and Electronic complementarity between different types of carbon nanotubes (CNT) and a tweezers-shaped molecule endowed with two exTTFs in water. The efficient Electronic Communication between semiconducting SWCNT/multiwall carbon nanotubes (MWCNT), on one hand, and the water-soluble exTTF nanotweezers 8, on the other hand, has been demonstrated in the ground and excited state by using steady-state as well as time-resolved spectroscopies, which were further complemented by microscopy. Importantly, appreciable Electronic Communication results in the Electronic ground state...

Electronic Communication in tetrathiafulvalene ttf c60 systems toward molecular solar energy conversion materials
Accounts of Chemical Research, 2007Co-Authors: Nazario Martin, Luis Sanchez, Maria Herranz, Beatriz M Illescas, Dirk M GuldiAbstract:The covalent connection of the electron acceptor C60 to p-quinonoid π-extended tetrathiafulvalenes (exTTFs) has allowed for the preparation of new photo- and electroactive conjugates able to act as artificial photosynthetic systems and active molecular materials in organic photovoltaics. The gain of aromaticity undergone by the π-extended TTF unit in the oxidation process results in highly stabilized radical ion pairs, namely, C60•–/exTTF•+. Lifetimes for such charge-separated states, ranging from a few nanoseconds to hundreds of microseconds, have been achieved by rationally modifying the nature of the chemical spacers. These long-lived radical pairs are called to play an important role for the conversion of sunlight into chemical or electrical power.

Pagers, Smartphones, and HIPAA: Finding the Best Solution for Electronic Communication of Protected Health Information
Journal of Medical Systems, 2017Co-Authors: Robert E. Freundlich, Katherine L. Freundlich, Brian C DroletAbstract:Electronic Communication is a topic that applies broadly to the professional activities of every physician and the pager has been the gold standard of Communication for decades. We believe that this is a dated technology that is holding clinicians back from better, more efficient alternatives, particularly smartphones. In this manuscript, we examine the paradoxical reliance on pagers in academic medicine, at a time when the use of smartphones and text messaging is the subject of intense scrutiny with respect to its standing under the Health Insurance Portability and Accountability Act (HIPAA). We provide previously unreported data regarding the Electronic Communication practices of academic medical centers in the United States, which we obtained through a survey of Designated Institutional Officials. These data highlight both the controversy around text messaging and HIPAA and a puzzling widespread reliance on pagers as an alternative.

Electronic Communication of protected health information privacy security and hipaa compliance
Journal of Hand Surgery (European Volume), 2017Co-Authors: Brian C Drolet, Jayson S Marwaha, Brad T Hyatt, Phillip E Blazar, Scott D LifchezAbstract:Purpose Technology has enhanced modern health care delivery, particularly through accessibility to health information and ease of Communication with tools like mobile device messaging (texting). However, text messaging has created new risks for breach of protected health information (PHI). In the current study, we sought to evaluate hand surgeons' knowledge and compliance with privacy and security standards for Electronic Communication by text message. Methods A cross-sectional survey of the American Society for Surgery of the Hand membership was conducted in March and April 2016. Descriptive and inferential statistical analyses were performed of composite results as well as relevant subgroup analyses. Results A total of 409 responses were obtained (11% response rate). Although 63% of surgeons reported that they believe that text messaging does not meet Health Insurance Portability and Accountability Act of 1996 security standards, only 37% reported they do not use text messages to communicate PHI. Younger surgeons and respondents who believed that their texting was compliant were statistically significantly more like to report messaging of PHI (odds ratio, 1.59 and 1.22, respectively). Discussion A majority of hand surgeons in this study reported the use of text messaging to communicate PHI. Of note, neither the Health Insurance Portability and Accountability Act of 1996 statute nor US Department of Health and Human Services specifically prohibits this form of Electronic Communication. To be compliant, surgeons, practices, and institutions need to take reasonable security precautions to prevent breach of privacy with Electronic Communication. Clinical relevance Communication of clinical information by text message is not prohibited under Health Insurance Portability and Accountability Act of 1996, but surgeons should use appropriate safeguards to prevent breach when using this form of Communication.

managing distance by interdependence goal setting task interdependence and team based rewards in virtual teams
European Journal of Work and Organizational Psychology, 2004Co-Authors: Guido Hertel, Udo Konradt, Borris OrlikowskiAbstract:Virtual teams, i.e., work groups in which members collaborate from distant locations predominantly based on Electronic Communication media, are increasingly introduced in organizations due to new opportunities of Electronic Communication media and recent trends of globalization and teamwork. Among the main challenges of virtual teams is the maintenance of high work motivation due to reduced face-to-face interaction. The current study examined whether these motivational challenges can be compensated by the experienced interdependence within virtual teams. Consistent with our expectations, the result of a field study with 31 virtual teams showed that management practices related to goal, task, and outcome interdependence correlated with the effectiveness of the teams. In more effective teams, quality of goal setting processes and task interdependence were higher compared to less effective teams. Positive effects of task interdependence were particularly present during the first year of virtual teamwork. Mor...

porphyrin triarylamine conjugates strong Electronic Communication between triarylamine redox centers via the porphyrin dication
Dalton Transactions, 2005Co-Authors: Jungche Chang, Shieming PengAbstract:A set of porphyrin–triarylamine hybrids have been synthesized in good yield by Sonogashira palladium-catalyzed cross-coupling reactions between the zinc complex of 5,15-diethynyl-10,20-dimesitylporphyrin and the appropriate iodophenyldiarylamines. The crystal structure of porphyrin 1 shows that the dihedral angle between the acetylene-bonded benzene rings and the porphyrin macrocycle is 20.0°. Such a structural characteristic enables effective Electronic perturbations within the molecule. The Electronic spectra are red-shifted and display a broad Soret band and an intense Q band relative to those of meso-substituted tetraarylporphyrins. These conjugates display four oxidations and one reduction. All the electrochemical reactions involve one-electron transfer. The first and second oxidations are reversible and can be assigned to the porphyrin-centered reactions. The third and fourth ones, separated by about 270 mV, correspond to the triarylamine units. The comproportionation constant (Kc) is calculated to be 3.67 × 104. The electron coupling between the triarylamine moieties, at a separation of >23 A, is remarkably strong. The electrochemical results and the absorption spectra show that the Electronic characteristics of these porphyrins can be significantly modulated by the triarylamine substituents via the conjugated carbon–carbon triple bond. Variations of the substituents on the triarylamines can fine-tune the Electronic properties of these molecules.

patient use of email facebook and physician websites to communicate with physicians a national online survey of retail pharmacy users
Journal of General Internal Medicine, 2016Co-Authors: Joy L Lee, Niteesh K Choudhry, Albert W Wu, Olga S Matlin, Troyen A Brennan, William H ShrankAbstract:Background Patient–physician Communication often occurs outside the clinic setting; many institutions discourage Electronic Communication outside of established Electronic health record systems. Little empirical data are available on patient interest in Electronic Communication and Web-based health tools that are technically feasible but not widely available.
