Following the path of hydrophobic and hydrophilic particles in a Denver Cell using positron emission particle tracking
Authors: Waters K. E. , Rowson N. A. , Fan X. , Cilliers J. J. 
Published: March 2009

AbstractPositron emission particle tracking (PEPT) has been used to track the movement of single particles of galena and quartz in a Denver Cell batch flotation system. The particles were labeled with a radionuclide, 18F, and using an ADAC Forte positron camera the positions of the particles were determined during mixing, and once air was added to the cell at a constant rate. The hydrophobic galena particle entered the froth readily, attached to air bubbles, and overflowed the weir. Detachment from an air bubble in the froth was also observed, and this is presumed to be due to coalescence events occurring. The hydrophilic quartz particle did not overflow the weir when the air flow was on. When the particle did enter the froth, it was along the sides of the vessel following the flow of the water. This gives a potential indication of one of the methods of the entrainment of gangue minerals in froth flotation. Copyright © 2009 Curtin University of Technology and John Wiley & Sons, Ltd.
Autothermal reforming of methane with integrated CO2 capture in novel fluidized bed membrane reactors
Authors: Gallucci F. , van Sint Annaland M. , Kuipers J. A. M. 
Published: March 2009

AbstractHydrogen production with integrated CO2 capture by autothermal reforming of methane has been investigated in a novel fluidized bed membrane reactor configuration. With a phenomenological reactor model the reactor performance has been investigated over a wide range of operating conditions, viz. temperature, pressure, H2O/CH4 ratio, and membrane area.The results obtained show that pure hydrogen production with integrated CO2 capture is feasible, however, only with a relatively low load/surface ratio (L/S) (<1 m3/m2 h). On the other hand, if complete CO2 capture is not the major aim, the reactor can be operated in a much wider range of L/S (1–10 m3/m2 h) obtaining much higher conversions than achievable with a reactor without membranes, and H2 recoveries higher than 80%, which open up possibilities for industrial application of membrane reactors.

Effect of oligosaccharide accumulated in the coagulation bath on the lyocell fiber process during industrial production
Authors: Zhang Huiru R. , Liu Xiaoyun , Li Dongshuang , Li Rongxian 
Published: March 2009

AbstractIn this article, we investigate the effects of oligosaccharide accumulated in the coagulation bath on the lyocell fiber process during industrial production. The research method consists of three parts. First, high‐performance liquid chromatography is used to analyze the monosaccharide composition of lyocell fibers and their pulp materials to determine whether the hemicelluloses in pulp material can be precipitated from the coagulation bath and then regenerated into lyocell fibers. Second, we establish a method for measuring the total sugar mixture content in the coagulation bath, which is a necessary technique during the industrial production of lyocell fibers. Third, we study the effect of oligosaccharide accumulated in the coagulation bath on the mechanical properties and supermolecular structure of lyocell fibers through a simulation experiment. © 2009 Wiley Periodicals, Inc.

Studies on the curing kinetics and thermal stability of diglycidyl ether of bisphenol‐A using mixture of novel, environment friendly sulphur containing amino acids and 4,4′‐diaminodiphenylsulfone
Authors: Darshan  , Malhotra Priti , Narula A. K. 
Published: March 2009

AbstractThis article describes the curing behavior of diglycidyl ether of bisphenol‐A using Cysteine (A)/ Methionine (B)/Cystine (C)/ mixture of 4,4′‐diaminodiphenyl sulfone (DDS) and Cysteine/DDS and Methionine/DDS and Cystine in various molar ratios as curing agent. Differential scanning calorimetry was used to study the cure kinetics by recording the DSC scans at heating rates of 5, 10, 15, and 20°C/min. The peak exotherm temperature was found to be dependent on the heating rate, structure of the amino acids and on the DDS/amino acids molar ratio. A broad exotherm was observed in the temperature range of 150–245°C (EA), 155–240°C (EB), and 190–250°C (EC). Curing of DGEBA with mixture of amino acids and 4, 4′‐diaminodiphenyl sulfone (DDS) resulted in a decrease in characteristic curing temperatures. Activation energy of curing reaction is determined in accordance to Ozawa's method and was found to be dependent on the structure of the amino acids and on the ratio of 4,4′‐diaminodiphenyl sulfone (DDS) to amino acid. Thermal stability of the isothermally cured resins was evaluated using dynamic thermogravimetry in nitrogen atmosphere. No significant change has been observed in the char yield of all the samples, but it was highest in the system cured using either Cystine alone (EC‐1) or a mixture of DDS/Cystine (EC‐2, EC‐3, and EC‐4). © 2009 Wiley Periodicals, Inc.

Effects of some electrospinning parameters on morphology of natural silk‐based nanofibers
Authors: Amiraliyan Nasim , Nouri Mahdi , Kish Mohammad Haghighat 
Published: March 2009

AbstractNatural silk, from Bombyx mori solutions were electrospun into nanofibers, with diameters ranged from 60 to 7000 nm. The effects of electrospinning temperature, solution concentration and electric field on the formation nanofibers were studied. Optical and scanning electron microscope were used to study the morphology and diameter of electrospun nanofibers. It was observed that the nanofibers became flattened with ribbon‐like shape with increasing the electrospinning temperature. The nanofiber diameter increases with the increase in the concentration of silk solution at all electrospinning temperature. With increasing the voltage of electric field at 50°C, morphology of the nanofibers changes from ribbon‐like structure to circular cross section. Referring to the literature the probable mechanism responsible for the change of morphology is pointed out. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2009
Similar processes despite divergent behavior in two commonly used measures of risky decision making

Published: March 2009

AbstractPerformance on complex decision‐making tasks may depend on a multitude of processes. Two such tasks, the Iowa Gambling Task (IGT) and Balloon Analog Risk Task (BART), are of particular interest because they are associated with real world risky behavior, including illegal drug use. We used cognitive models to disentangle underlying processes in both tasks. Whereas behavioral measures from the IGT and BART were uncorrelated, cognitive models revealed two reliable cross‐task associations. Results suggest that the tasks similarly measure loss aversion and decision‐consistency processes, but not necessarily the same learning process. Additionally, substance‐using individuals (and especially stimulant users) performed worse on the IGT than healthy controls did, and this pattern could be explained by reduced decision consistency.

Short‐term lime pretreatment of poplar wood
Authors: Sierra Rocio , Granda Cesar , Holtzapple Mark T. 
Published: March 2009

AbstractShort‐term lime pretreatment uses lime and high‐pressure oxygen to significantly increase the digestibility of poplar wood. When the treated poplar wood was enzymatically hydrolyzed, glucan and xylan were converted to glucose and xylose, respectively. To calculate product yields from raw biomass, these sugars were expressed as equivalent glucan and xylan. To recommend pretreatment conditions, the single criterion was the maximum overall glucan and xylan yields using a cellulase loading of 15 FPU/g glucan in raw biomass. On this basis, the recommended conditions for short‐term lime pretreatment of poplar wood follow: (1) 2 h, 140°C, 21.7 bar absolute and (2) 2 h, 160°C, and 14.8 bar absolute. In these two cases, the reactivity was nearly identical, thus the selected condition depends on the economic trade off between pressure and temperature. Considering glucose and xylose and their oligomers produced during 72 h of enzymatic hydrolysis, the overall yields attained under these recommended conditions follow: (1) 95.5 g glucan/100 g of glucan in raw biomass and 73.1 g xylan/100 g xylan in raw biomass and (2) 94.2 g glucan/100 g glucan in raw biomass and 73.2 g xylan/100 g xylan in raw biomass. The yields improved by increasing the enzyme loading. An optimal enzyme cocktail was identified as 67% cellulase, 12% β‐glucosidase, and 24% xylanase (mass of protein basis) with cellulase activity of 15 FPU/g glucan in raw biomass and total enzyme loading of 51 mg protein/g glucan in raw biomass. Ball milling the lime‐treated poplar wood allowed for 100% conversion of glucan in 120 h with a cellulase loading of only 10 FPU/g glucan in raw biomass. © 2009 American Institute of Chemical Engineers Biotechnol.

Published: March 2009

AbstractAll light and no heat?Structure–property relationships for photochromic and thermochromicN‐salicylideneanils have been revised (see picture). One derivative has a packed crystal structure, is photochromic and exhibits an infinitely slow thermal back relaxation of technological interest. Complexation of the anils to transition metals has also been studied.magnified imageThe relationships between the crystal structure and optical properties of switchableN‐salicylideneanils have been revised and discussed on the basis of new experimental results and a computational approach.N‐Salicylidene‐3‐aminopyridine (L3) is a versatile thermo‐ and photochromic molecule. It also exhibits an infinitely slow thermal back relaxation (k=9.9×10−8 s−1) after photoswitching that is suitable for optical memories. Contrary to reports in the literature,N‐salicylidene‐4‐aminopyridine (L4) is exclusively thermochromic. To explain these unexpected optical properties in the solid state, crystallography combined with UV‐visible spectroscopic data was exploited.L3was also used as a ligand in new thermochromic coordination complexes [M(CH3OH)2(L3)2(NCX)2], in which MII=Fe, Co, Ni, Cu or Mn and X=S or Se (1–6), which allowed the fine‐tuning of the electron density in the photochromic moiety. The influence of the coordination through the nitrogen of the pyridine ring is also fully discussed.
