Effects of melt‐extension and annealing on row‐nucleated lamellar crystalline structure of HDPE films
Authors: Lee Sang‐Young , Park Soon‐Yong , Song Heon‐Sik 
Published: December 2006

AbstractThe row‐nucleated lamellar crystalline structure of high‐density polyethylene (HDPE) films was prepared by applying elongation stress to HDPE melt during T‐die cast film extrusion and subsequently annealing the extruded films. This unusual crystalline structure was analyzed in terms of lamellar crystalline orientation, long‐period lamellar spacing, crystallite size, and degree of crystallinity. The contribution of melt‐extension represented by draw‐down‐ratio (DDR) to the overall orientation was found to be most noticeable than other processing variables. Meanwhile, the long‐period lamellar spacing, the crystallite size, and the degree of crystallinity were influenced predominantly by the annealing temperature. Finally, the processing (melt extension and annealing temperature) – structure (lamellar crystalline structure) – property (hard elasticity) relationship of HDPE films was investigated. © 2006 Wiley Periodicals, Inc.

Sustained release of iodine from a polymeric hydrogel device for water disinfection
Authors: Punyani Supriya , Narayanan Priya , Vasudevan Padma , Singh Harpal 
Published: December 2006

Abstract2‐Hydroxyethyl methacrylate (HEMA) based polymeric hydrogels were synthesized by free‐radical redox bulk polymerization technique using 1% ethyleneglycol dimethacrylate (EGDMA) as crosslinking monomer and ammonium persulfate (APS) and N,N,N′,N′‐tetramethyl ethylenediamine (TEMED) as redox initiator. Polymeric hydrogel samples were loaded with solid elemental iodine. Thermal and physical characteristics of polymer before loading and after 3 months release of iodine were evaluated by differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). On immersing in water, different forms of iodine were released from the hydrogel device. The amount and rate of release of I− and I were measured by analytical techniques. Released iodine species showed broad spectrum antimicrobial properties and release was sustained for about 120 days. Polymeric hydrogel iodine‐based system developed can be used as a device for controlled release of iodine species at concentration levels sufficient for disinfection to get potable water. © 2006 Wiley Periodicals, Inc.

Effects of p‐hydroxybenzoic acid monomer units on physical properties of thermal liquid crystalline poly(ester imide ketone)s
Authors: Xu Jun , Zhu Yafei , Zhang Yi , Zheng Yimin , Chi Zhenguo , Xu Jiarui 
Published: December 2006

AbstractA series of poly(ester imide ketone)s (PEIKs) with varied p‐hydroxybenzoic acid (HBA) molar fraction derived from N,N′‐hexane‐1,6‐diylbis(trimellitimide), 4,4′‐dihydroxybenzophenone, and p‐hydroxybenzoic acid were synthesized by a “step‐feeding” polycondensation method in benzene sulfonyl chloride, dimethylformamide, and pyridine. High field 1H, 13C, and 2D NMR spectroscopy measurements were combined to determine the assignments of hydrogen and carbon atoms in the copolymers. 13C inverse gated decoupling NMR spectra were taken and used as a quantitative method to analyze the chain sequence structures of these copolymers. The liquid crystalline behaviors and thermal properties of the PEIKs were characterized by polarized light microscopy (PLM), wide‐angle X‐ray diffraction (WAXD), differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA). The NMR studies show that the monomeric unit ratios of the PEIKs are very close to the ratios of the monomers added into the polycondensation process. The analytical results of sequence distribution indicate that the sequence ratios of I‐H, H‐D, and H‐H dias rise with the increase of HBA molar fraction, while that of I‐D decrease. It is worth noting that the sequence ratios of H‐H are always very small among the four sequence ratios although the HBA molar fraction varied from 0 to 50%. It was shown that the copolymers possess a typical nematic thermotropic liquid crystalline character and high thermal stability, which is strongly related with the changes in sequence structure of the molecular chains. This type of liquid crystalline polymers also exhibits excellent fiber‐forming character in the melting state, which would find its potential usages in high performance fiber and fiber modification materials. © 2006 Wiley Periodicals, Inc.

Sustainability report in small enterprises: case studies in Italian furniture companies
Authors: Borga Francesca , Citterio Annalisa , Noci Giuliano , Pizzurno Emanuele 
Published: December 2006

AbstractThe recent evolution of the economic and social context has led enterprises to consider and assess corporate environmental and social impacts integrated with the traditionally measured economic and operating performances.  From this point of view, the international debate on the advantages given by the firms' adoption of socially responsible behaviour has been developed; the increasing consciousness of the social character in enterprises' activities has enlarged the interest in communication. For this reason, several different standards have been developed in order to transmit, to the stakeholders, data, information and approaches about environmental, social and sustainability topics related to the firm's activities. In this dynamic context, the features of SMEs require specific guidelines, which address the contents of an SME‐oriented sustainability report.  In this perspective the aim is to design guidelines able to meet with these SMEs' requirements; seven case studies, on Italian furniture small enterprises, complete the study.

The impact of environmental information on professional purchasers' choice of products
Authors: Grankvist Gunne , Biel Anders 
Published: December 2006

AbstractProfessional food purchasers are an important group of people since they influence what alternatives of a food product consumers will have the possibility to choose between. The aim of the present study was to investigate the inclination among professional purchasers to choose food products associated with more benign environmental consequences.  Information about product price, total use of energy, emission of greenhouse gases and use of pesticides associated with production and consumption of one kilogram of minced beef and fresh apples was varied systematically in order to study the relative influence on product preference. Product price was found to influence product preference more than any of the three environmentally related factors. Introduction of a labeling system that indicated whether the environmental impacts associated with a food product during its life cycle were ‘better’ or ‘worse’ than an average product partly increased the effect of environmental information.

Reaction Chemistry of Complexes Containing PtH, PtSH, or PtS Fragments: From Their Apparent Simplicity to the Maze of Reactions Underlying Their Interconversion

Published: December 2006

AbstractThe relevance of platinum in the reaction of thiophene and derivatives with homogeneous transition‐metal complexes as models for hydrodesulfurization has led us to the study of the reaction chemistry of complexes containing PtH, PtSH, and PtS fragments. Exploration of the reactions triggered by addition of controlled amounts of Na2S or NaSH to [Pt2(H)2(μ‐H)(dppp)2]ClO4 (1) has provided evidence of the formation of complexes [Pt2(μ‐H)(μ‐S)(dppp)2]ClO4 (2), [Pt(H)(SH)(dppp)] (3), [Pt2(μ‐S)2(dppp)2] (4), [Pt2(μ‐S)(dppp)2] (5) and [Pt(SH)2(dppp)], in which dppp denotes 1,3‐bis(diphenylphosphanyl)propane. Consequently, complexes 1, 2, and 5 as well as the already reported 3, 4, and [Pt(SH)2(dppp)] have been obtained and fully characterized spectroscopically. Also the crystal structures of 1 and 2 have been solved. Complexes 1–5 constitute the main framework of the network of reactions that account for the evolution of 1 under various experimental conditions as shown in Scheme 1. Apparently, this network has complexes 2 and 4 as dead‐ends. However, their reciprocal interconversion by means of the replacement of one bridging hydride or sulfide ligand in the respective {Pt(μ‐H)(μ‐S)Pt} and {Pt(μ‐S)2Pt} cores enables the closure of the reaction cycle involving complexes 1–5. Theoretical calculations support the existence of the undetected intermediates proposed for conversion from 1 to 2 and from 3 to 2 and also account for the fluxional behavior of 1 in solution. The intermediates proposed are consistent with the experimental results obtained in comparable reactions carried out with labeled reagents, which have provided evidence that complex 1 is the source of the hydride ligands in complexes 2 and 3. Overall, our results show the strong dependence on the experimental conditions for the formation of complexes 1–5 as well as for their further conversion in solution.
The Effect of Water on the Microstructure of 1‐Butyl‐3‐methylimidazolium Tetrafluoroborate/TX‐100/Benzene Ionic Liquid Microemulsions

Published: December 2006

AbstractThe ionic liquid (IL) 1‐butyl‐3‐methylimidazolium tetrafluoroborate ([bmim][BF4]) forms nonaqueous microemulsions with benzene with the aid of nonionic surfactant TX‐100. The phase diagram of the ternary system was prepared, and the microstructures of the microemulsion were recognized. On the basis of the phase diagram, a series of ionic liquid‐in‐oil (IL/O) microemulsions were chosen and characterized by dynamic light scattering (DLS), which shows a similar swelling behavior to typical water‐in‐oil (W/O) microemulsions. The existence of IL pools in the IL/O microemulsion was confirmed by UV/Vis spectroscopic analysis with CoCl2 and methylene blue (MB) as the absorption probes. A constant polarity of the IL pool is observed, even if small amounts of water are added to the microemulsion, thus suggesting that the water molecules are solubilized in the polar outer shell of the microemulsion, as confirmed by FTIR spectra. 1H NMR spectroscopic analysis shows that these water molecules interact with the electronegative oxygen atoms of the oxyethylene (OE) units of TX‐100 through hydrogen‐bonding interactions, and the electronegative oxygen atoms of the water molecules attract the electropositive imidazolium rings of [bmim][BF4]. Hence, the water molecules are like a glue that stick the IL and OE units more tightly together and thus make the microemulsion system more stable. Considering the unique solubilization behavior of added water molecules, the IL/O microemulsion system may be used as a medium to prepare porous or hollow nanomaterials by hydrolysis reactions.
