“…159e163 The most representative element of this family of OEMs is undoubtedly PTMA ( Table 6.2, entry II), which has a theoretical capacity of 111 mAh/g. 170 As previously explained in paragraph 2 of this chapter, the sulfur element is intrinsically interesting due to its multielectron redox chemistry but the production of soluble Ps as the discharge/charge proceed constitutes a brake in developing efficient Li-S batteries. However, the low electronic conductivity of such redox-active polymers implies the use of high loadings of conductive additive limiting the specific capacity of a practical composite PTMA-based electrode to w55 mAh/g.…”

“…The C theo (374 mAh g − 1 ) and discharge potential ( ∼ 2.2 V vs Li/Li + ) of thioether 48 was just comparable to that of disulfi des, but the cycling stability is remarkably improved. [ 86 ] Considering that the thiophene core in 51 also undergoes reversible p-doping, Zhan et al supposed that oxidation and reduction occur at the thiophene and S + sites, S S n REVIEW respectively, followed by intramolecular electron transfer to each other. To eliminate the nonplanarity between the thiolane ring and the polyphenyl main chain for better electron transfer, thioether 49 was synthesized.…”

Organic compounds offer new possibilities for high energy/power density, cost-effective, environmentally friendly, and functional rechargeable lithium batteries. For a long time, they have not constituted an important class of electrode materials, partly because of the large success and rapid development of inorganic intercalation compounds. In recent years, however, exciting progress has been made, bringing organic electrodes to the attention of the energy storage community. Herein thirty years' research efforts in the fi eld of organic compounds for rechargeable lithium batteries are summarized. The working principles, development history, and design strategies of these materials, including organosulfur compounds, organic free radical compounds, organic carbonyl compounds, conducting polymers, non-conjugated redox polymers, and layered organic compounds are presented. The cell performances of these materials are compared, providing a comprehensive overview of the area, and straightforwardly revealing the advantages/disadvantages of each class of materials.

“…For example, EDTT has a lower oxidation potential compared to EDOT, and there is a better electronic interaction between polymer chains through intermolecular S … S attractions in PEDTT than PEDOT 15, 35, 39, 40. Nowadays, PEDTT and its derivatives have found possible applications as the electron donor materials in photovoltaic devices,35, 37, 38, 41–44 and as the cathode active materials for rechargeable lithium batteries with better cathode capacity than PEDOT 45. More recently, electrosynthesized PEDTT materials were introduced into organic electronic display field and sensors owing to their electrochromic and electrochemical catalytic properties 21, 46–48.…”

BACKGROUND: Magnetic resonance imaging (MRI) has been used to supplement screening mammography and clinical breast examination (CBE) in women who are at high risk of developing breast cancer. In this study, the authors investigated the efficacy of alternating screening mammography and breast MRI every 6 months in women who had a genetically high risk of developing breast cancer. METHODS: A retrospective chart review was performed on all women who were seen in a high-risk breast cancer clinic from 1997 to 2009. Patients with breast cancer gene (BRCA) mutations who underwent alternating screening mammography and breast MRI every 6 months were included in the study. Mammography, ultrasonography, MRI, and biopsy results were reviewed. RESULTS: Of 73 patients who met the study criteria, 37 had BRCA1 mutations, and 36 had BRCA2 mutations. Twenty-one patients (29%) completed 1 cycle of mammography and MRI surveillance, 23 patients (31%) completed 2 cycles, 18 patients (25%) completed 3 cycles, and patients 11 (15%) completed !4 cycles. The median follow-up was 2 years (range, 1-6 years). Thirteen cancers were detected among 11 women (15%). The mean tumor size was 14 mm (range, 1-30 mm), and 2 patients had bilateral cancers. Twelve of 13 cancers were detected on an MRI but not on the screening mammography study that was obtained 6 months earlier. One cancer (a 1-mm focus of ductal carcinoma in situ) was an incidental finding in a prophylactic mastectomy specimen. One patient had ipsilateral axillary lymphadenopathy identified on ultrasonography but had no evidence of lymph node involvement after neoadjuvant chemotherapy and surgery. CONCLUSIONS: In women who were at genetically high risk of developing breast cancer, MRI detected cancers that were not identified on mammography 6 months earlier. Future prospective studies are needed to evaluate the benefits of this screening regimen.
