Sustainable geopolymers from polyethylene terephthalate waste and industrial by-products: a comprehensive characterisation and performance predictions

Full text linkThe lipase, Novozyme®-435, exclusively deacetylates the 5-O-acetyl over 4-C-acetyloxymethyl group of almost identical reactivity in 5-O-acetyl-4-C-acetyloxymethyl-3-azido-3-deoxy-1,2-O-isopropylidene-?-D-ribofuranose that led to the development of first and efficient synthesis of 3?-azido-/3?-amino-C-4?-spiro-oxetanoribonucleosides T, U, C and A in 20–24% overall yields. The X-ray study on the compound obtained by tosylation of lipase-mediated monodeacetylated product unambiguously confirmed the point of diastereoselective monodeacetylation on diacetoxy-azido-ribofuranose derivative. The capability of Novozyme®-435 for selective deacylation of 5-O-acetyl group in 5-O-acetyl-4-C-acetyloxymethyl-3-O-benzyl-1,2-O-isopropylidene-?-D-ribofuranose recently discovered by us has been successfully used for the synthesis of C-4?-spiro-oxetanoribonucleosides A and C in good yields. These results clearly indicate that the broader substrate specificity and highly selective capability of Novozyme®-435 for carrying out acetylation/deacetylation reactions can be utilized for the development of environment friendly selective methodologies in organic synthesis
Forest observational studies in India: Past developments and considerations for the future
No full textLong term forest research sites in India, going by different names including Linear Tree Increment Plots, Linear Increment Plots, Linear Sample Plots and Permanent Preservation Plots, cover diverse plant communities and environmental conditions. Presently, some of these long-term observational studies are functional, some are disturbed and others have almost been lost. The accumulated data will become increasingly important in the context of environmental modelling and climate change, especially if the plots and data can be maintained and/or revived. This contribution presents the history and current state of forest research plots in India, including details of locations and re-measurements. We provide a brief introduction of the National Forest Inventory (NFI), Preservation Plots in natural forests, the 50-ha Mudumalai Forest Dynamics Plot as part of the Centre for Tropical Forest Science and Smithsonian Institution Global Earth Observatories network (CTFS-SIGEO), and research plots established in plantations for tree growth studies and modelling. We also present some methodological details including assessment and analysis for two types of observational studies, the Tree Count Plots (TCP) and Tree Re-measurement Plots (TRP). Arguments are presented in favour of enumeration and analysis methods which are consistent with current approaches in forest ecological research. (c) 2013 Elsevier B.V. All rights reserved
Improvement of hydrogen storage characteristics of carbon nanostructural variants admixed nano MgH2
No full textIn the present work, we have synthesized and studied the catalytic effect of different carbon nanostructures (CNSs) on the absorption kinetics, decomposition temperature of MgH2. Ball-milling was used to reduce the particle size of MgH2 and CNS catalysts were used to enhance the hydrogen storage properties at lower temperatures. In particular, 2wt% twisted carbon nanofibres (TCNF) admixed ball-milled MgH2 (MgH2-2TCNF) corresponds to better hydrogenation/ dehydrogenation behaviour. The commencement of H-desorption temperature is ∼420 ?C for pure MgH2, ∼ 330 °C for TCNF admixed MgH2, which is further lowered to 297 °C for TCNF admixed ball-milled MgH2. Thus, desorption temperature gets more than 125 °C lower compared to commercial MgH2. After the desorption, Mg- 2TCNF (ballmilled) shows 5.03 wt% absorption as compared to 3.05 wt% for the ball milled MgH2 in the first 10 minutes even at 180 °C and an applied pressure of 2MPa. Whereas in the case of 2TCNF admixed MgH2 it shows absorption of 4.28 wt% at a higher temperature 300 °C and an applied pressure of 2 MPa. The improved properties originate due to the CNSs catalyst and nanostructure of MgH2 introduced during ball milling in hydrogen pressure
When an intercultural business negotiation fails: comparing the emotions and behavioural tendencies of individualistic and collectivistic negotiators
Full text linkThis study explores the linkages between culture, emotions and behavioural tendencies in unsuccessful intercultural business negotiations. A set of novel research hypotheses are developed. They are tested using a negotiation scenario analysis involving 106 Finnish and 114 Indian study participants. Three key findings emerge from the statistical tests conducted. First, new empirical evidence suggesting that qualitatively different emotions (dejection vs. agitation) are experienced after a failed intercultural business negotiation by individualists and collectivists is provided. Second, the existence of the relationship between perspective-taking ability and emotional volatility in the context of failed intercultural business negotiation involving individualists and collectivists is revealed. Third, partial support is found for the idea that different types of negative emotions can lead to the same behavioural tendency (approach) among individualists and collectivists when intercultural business negotiation fails. The paper concludes by outlining a set of theoretical and managerial implications and suggestions for further research
