Sustainability, Vol. 8, Pages 428: From Life Cycle Costing to Economic Life Cycle Assessment—Introducing an Economic Impact Pathway

29-Apr-2016 | Neugebauer, Sabrina ; Forin, Silvia ; Finkbeiner, Matthias, Sustainability, 2016

Economic activities play a key role in human societies by providing goods and services through production, distribution, and exchange. At the same time, economic activities through common focus on short-term profitability may cause global crisis at all levels. The inclusion of three ...

Reaction of aerogel containing ceramic fibre insulation to fire exposure

25-Apr-2016 | K. Ghazi Wakili, A. Remhof, Fire and Materials, 2016

SUMMARY Aerogel containing ceramic fibre insulations represent a newly developed high performance insulation material applied in industrial installations and recently expanding rapidly into the construction industry to reduce the heat transfer through walls and ceilings. As a rather expensive ...

Hydrothermal synthesis, structures and properties of two uranyl oxide hydroxyl hydrate phases with Co(II) or Ni(II) ions

20-Apr-2016 | Yingjie Zhang; Jiri Cejka; Gregory R Lumpkin; Trong Toan Tran; igor aharonovich; Inna Karatchevtseva; Jason R. Price ..., New Journal of Chemistry, 2016

Two new iso-structured uranyl oxide hydroxyl hydrate (UOH) phases with incorporation of cobalt(II) or nickel(II) ions have been synthesised under hydrothermal conditions and structurally characterised. Both K4Co(OH)3(H2O)9[(UO2)12(O)7(OH)13] (1) and K4Ni(OH)3(H2O)9[(UO2)12(O)7(OH)13] (2) have ...

Tuning the adsorption behaviors of water, methanol, and ethanol in a porous material by varying the flexibility of substituted groups

19-Apr-2016 | Yunfei Sha; Shizhe Bai; Jiaying Lou; Da Wu; Baizhan Liu; Yun Ling, Dalton Transactions, 2016

Exploring the adsorption and separation of water, methanol, and ethanol is important concerning the use of a sustainable energy source from biofuel. In this paper, the effects of the flexibility of substituted groups have been studied based on three iso-reticular metal–organic frameworks (MOFs), ...

Entropy, Vol. 18, Pages 137: Operational Complexity of Supplier-Customer Systems Measured by Entropy—Case Studies

14-Apr-2016 | Lukáš, Ladislav ; Hofman, Jiří, Entropy, 2016

This paper discusses a unified entropy-based approach for the quantitative measurement of operational complexity of company supplier-customer relations. Classical Shannon entropy is utilized. Beside this quantification tool, we also explore the relations between Shannon entropy and (c,d)-entropy ...

On the Highest Oxidation States of Metal Elements in MO4 Molecules (M = Fe, Ru, Os, Hs, Sm, and Pu)

13-Apr-2016 | Wei Huang; Wen-Hua Xu; W. H. E. Schwarz; Jun Li, Inorganic Chemistry, 2016

Metal tetraoxygen molecules (MO4, M = Fe, Ru, Os, Hs, Sm, Pu) of all metal atoms M with eight valence electrons are theoretically studied using density functional and correlated wave function approaches. The heavier d-block elements Ru, Os, Hs are confirmed to form stable tetraoxides of Td ...

Facile kinetic induction of a dihydropyridide to pyrrolide ring contraction

06-Apr-2016 | David R. Carbery; Michael S. Hill; Mary F. Mahon; Catherine Weetman, Dalton Transactions, 2016

Reactions between magnesium 1,4-dihydropyridide or 1,2-dihydro-iso-quinolide derivatives and carbodiimides, RN [[double bond, length as m-dash]] C [[double bond, length as m-dash]] NR, generally result in Mg–N insertion and formation of guanidinate complexes. More sterically perturbed systems ...

Factors affecting the measurement of photochromic lens performance

01-Apr-2016 | Liu Ouyang, Hongliang Huang, Yong Tian, Wei Peng, Huanbao Sun, Weizhong Jiang, Coloration Technology, 2016

The principles, characteristics, and measurement methodology of photochromism of plastic ophthalmic lenses are briefly introduced and discussed. The factors influencing measurement variation and accuracy, including the preconditioning process, measurement device, and procedure, were investigated ...

Determination of critical heat transfer for the prediction of materials damages during a flame engulfment test

30-Mar-2016 | Michel Schmid, Simon Annaheim, Martin Camenzind, René M. Rossi, Fire and Materials, 2016

Summary The personal protective equipment of workers exposed to heat can consist of materials with a relatively low melting point of approximately 250°C (membranes, zippers, and underwear). In particular, users of heat protective clothing (such as volunteer firefighters or industrial workers) ...

Molecular Engineering as an Approach To Design a New Beryllium-Free Fluoride Carbonate as a Deep-Ultraviolet Nonlinear Optical Material

30-Mar-2016 | Min Luo; Yunxia Song; Chensheng Lin; Ning Ye; Wendan Cheng; XiFa Long, Chemistry of Materials, 2016

It is a great challenge to explore deep-ultraviolet (deep-UV) nonlinear optical (NLO) materials that can achieve a subtle balance among large nonlinear coefficients, moderate birefringence, and deep-ultraviolet (UV) transparency. A new beryllium-free fluoride carbonate Ca2Na3(CO3)3F was ...
