Investigation of cellulose supramolecular structure changes during conversion of waste paper in near-critical water on producing 5-hydroxymethyl furfural

Wan, Jinquan; Lian, Jie; Wang, Yan; Ma, Yongwen - In: Renewable Energy 80 (2015) C, pp. 132-139

Waste paper as a kind of biomass contains a great quantity of cellulose which is a renewable energy resource. However, complex cellulose supramolecular structure restricts the conversion of waste paper in near-critical water. This study aimed to investigate the change characteristics of...

STRUCTURAL AND OPTICAL PROPERTIES OF n-TYPE POROUS SILICON — EFFECT OF HF CONCENTRATION

JEYAKUMARAN, N.; NATARAJAN, B.; RAMAMURTHY, S.; VASU, V. - In: Surface Review and Letters (SRL) 14 (2007) 02, pp. 293-300

Porous silicon layers have been prepared from n-type silicon wafers of (100) orientation. SEM, XRD, FTIR, and PL have been used to characterize the morphological and optical properties of porous silicon. The influence of varying HF concentration in the anodizing solution, on structural and...

STRUCTURAL AND OPTICAL PROPERTIES OF n-TYPE POROUS SILICON: EFFECT OF LIGHT ILLUMINATION

JEYAKUMARAN, N.; NATARAJAN, B.; PRITHIVIKUMARAN, N.; … - In: Surface Review and Letters (SRL) 15 (2008) 06, pp. 897-901

Porous silicon (PS) layers have been prepared from n-type silicon wafers of (100) orientation. SEM, FTIR, and PL have been used to characterize the morphological and optical properties of PS. The influence of varying light illumination in the anodizing solution, on structural and optical...

Minireview: The compact phase in polymers and proteins

Seno, F.; Trovato, A. - In: Physica A: Statistical Mechanics and its Applications 384 (2007) 1, pp. 122-127

Proteins are linear molecules. However, the simple model of a polymer viewed as spheres tethered together does not account for many of the observed characteristics of protein structures. Here we review some recent works tackling this problem. In particular, we will show that there is a growing...

Water behavior in the neighborhood of hydrophilic and hydrophobic membranes: Lessons from molecular dynamics simulations

Chara, Osvaldo; McCarthy, Andrés N.; Ferrara, C. Gastón; … - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 21, pp. 4551-4559

The study of properties of water in the vicinity of surfaces poses a fascinating challenge. In this article we studied the behavior of water molecules in the neighborhood of membranes. We addressed the question of how these water molecules are influenced by the membranes’ hydrophilicity. Three...

Finite sample correction factors for panel cointegration tests

Hlouskova, Jaroslava; Wagner, Martin - 2009

In this paper we present finite T mean and variance correction factors and corresponding response surface regressions for the panel cointegration tests presented in Pedroni (1999, 2004), Westerlund (2005), Larsson et al. (2001), and Breitung (2005). For the single equation tests we consider up...

Reproducible Econometric Simulations

Kleiber, Christian; Zeileis, Achim - 2011

Reproducibility of economic research has attracted considerable attention in recent years. So far, the discussion has focused on reproducibility of empirical analyses. This paper addresses a further aspect of reproducibility, the reproducibility of computational experiments. We examine the...

Standard and Shuffled Halton Sequences in a Mixed Logit Model

Staus, Alexander - 2008

. Simulation methods have been developed to approximate a solution for these integrals. This paper describes the Standard Halton … sequence and a modification of it, the Shuffled Halton sequence. Both are simulation methods which can reduce computational … effort compared to a random sequence. We compare the simulation methods in their coverage of the multi-dimensional area and …
