Title: T-shaped unsymmetrical azoester based mesogenic dimers Authors: Varia, M C; Kumar, Sandeep; Prajapati, A K Abstract: There could be several potential applications of LC dimers due to their distinct nature and unusual properties. Both symmettic and non-symmetric dimers exhibit a rich smectic polymorphism. Blatch et al reported the non-symmetric dimers from cyanobiphenyl mesogen connected to a cinnamoate moiety through a flexible spacer which exhibited as intercalated smectic A phase. Jin et al have studied in detail the smectic phase behaviour of non-symmetric dimers containing a cholesteryl unit linker to a conventional calamitic mesogenic unit via a flexible alkyl spacer. Several examples of non-symmetrical charge-transfer dimers in which a triphenylene- based unit is connected to an electron-deficient non-liquid crystalline THF of anthraquinone moiety. The synthesis of dimer, in which there is an amide group in the linking chain, was reported by Boden dt al. An interesting example of non-symmetric discotic donot-σ-acceptor dimer reported by Kumar et al. The strong nematic tendencies of the T-shaped dimers implies that the spacer adopts conformations for which the two mesogenic units are held more or less coparallal. This view is supported by the weaker dependence of the spacers seen for the T-shaped dimers that observed for conventional linear dimers. Nori et al have reported the purely nematogenic T-shaped compounds which having the polymethylene spacers with six benzene bridging through the four ester group. Yoshizawa et al have designed novel T-shaped and bent chiral compounds possessing molecular biaxiality, and invertigated the chirality-dependent properties. Weissflog et al have reported the T-shaped compounds with having the nematic mesophases and smectic A mesophases. Description: Open Access

Title: RRI Digital repository as a tool to support scholarly research Authors: Benegal, Vrinda J.; Sheshadri, Geetha Abstract: Digital Institutional Repository is a vehicle to showcase the research output of an institution. It becomes important as it is a natural extension of the Academic/Research Libraries responsibility as a promoter of primary research, seeking to preserve and patronage and build up its intellectual assets. This poster illustrates the role of RRI Digital Repository in supporting and enhancing research work in RRI. The Digital Repository of RRI is a place where the library, collects, curates, preserves and provides access to scholarly literature of RRI Academia. Description: Open Access

Title: Current status of the X-ray polarimeter Authors: Rishin, P.V.; Gopalakrishna, M.R.; Paul, Biswajit; Duraichelvan, R.; Ateequlla, C.M.; Maitra, Chandreyee; Rajagopala, G.; Nagaraja, H N; Ezhilarasi, M.S.; Sandhya, P.; Mamatha, T.S. Abstract: We describe the current status of a Thomson X-ray polarimeter developed for a small satellite mission. Currently, a laboratory model has been made and tested successfully and the design and fabrication of an engineering model is in progress. This involves, re-design of the currently developed lab model, taking into consideration the different standards required for space qualification. We describe the design aspects of the detector, front-end electronics and the processing electronics. Description: Open Access
