Structure effect of benzofuranone on the anti‐oxidation kinetics in polypropylene
Authors: Cai Zhi , Meng Xin , Shen Benxian , Xin Zhong 
Published: August 2010

AbstractBenzofuranone compounds are used as chain‐breaking antioxidants in the melt processing of polymers owing to their strong hydrogen donating ability. In this article, the structural effects of benzofuranone compounds on anti‐oxidation in polypropylene (PP) were evaluated using oxidation onset temperature (OOT) of PP stabilised by the compounds in oxygen and the oxidation kinetics of the PP was studied using Ozawa and Kissinger methods, respectively. The results show that benzofuranone compounds inhibit the oxidative degradation of PP by increasing the oxidation activation energy, and the higher the oxidation activation energy of PP, the better the anti‐oxidation activity of benzofuranone in PP. Furthermore, the anti‐oxidation activity of benzofuranone compounds in PP is weakened by the methyl group in the 2′‐position. Compared to benzofuranone compounds OXBF1 and TBF1 without 2′‐position methyl group, PP stabilised by benzofuranone compound MXBF1 with 2′‐position methyl group has lower OOT values and smaller oxidation activation energy.

Relationship between nitrogenous species in coals and volatile nitrogen‐containing yields during pyrolysis
Authors: Wang Zonghua , Zhang Junying , Zhao Yongchun , Zheng Chuguang 
Published: August 2010

AbstractNitrogen in coal is a major pollutant that inhibits the effective and extensive utilization of coal, and hence, nitrogen removal during and after coal combustion is of great importance. Future utilization of coal requires accurate knowledge of its structure and properties. Datong coal (DT, bituminous coal), Huolinhe coal (NM, brown coal) and Fushun coal (FS, brown coal) were pyrolyzed in a fixed‐bed reactor under argon atmosphere with a heating rate of 15 °C/min. X‐ray photoelectron spectroscopy (XPS) was used to investigate the presence of nitrogen in the coals and their chars obtained from pyrolysis. The nitrogenous components in the product gases were analyzed by Fourier transform infrared (FT‐IR) spectrometer. The results indicate that N‐5 is the main nitrogen‐bearing compound in DT coal and NM coal, whereas in FS coal N‐6 is the main nitrogen‐bearing compound. After pyrolysis at 600 °C, the quantity of N‐6 in the char rises for DT coal, and drops for NM coal and FS coal. After pyrolysis at 1000 °C, the quantity of N‐6 decreases significantly for FS coal, and considerable quantity of N‐Q is detected. NH3, HCN, and NO were identified among the gases resulting from pyrolysis, with the HCN and NO yields being lower than the NH3 yields. In coal pyrolysis, the initial formation temperature of NH3 is approximately the same as that of HCN. The temperatures are almost identical when the concentrations of NH3 and HCN reach their maxima for DT coal and FS coal. The formation of HCN starts at a temperature of about 400 °C, and below 700 °C, considerable amounts of HCN and NH3 are produced. The amount of nitrogen released increases with the temperature at which pyrolysis takes place, the maximum release rate being 81.28% at 1000 °C.

Reinforcement learning framework for adaptive control of nonlinear chemical processes
Authors: Shah Hitesh , Gopal Madan 
Published: August 2010

AbstractThis article addresses the problem of adaptive control of nonlinear chemical processes with time‐varying dynamics. TheQ‐learning and policy‐iteration algorithms have been considered in the reinforcement learning (RL) framework. The performance of the two algorithms has been tested on highly nonlinear simulated continuous stirred tank reactor (CSTR). Comparison with conventional methods shows that the RL techniques are able to achieve better performance, and robustness against uncertainties. The policy‐iteration algorithm is relatively faster in convergence, and better in robustness. Copyright © 2010 Curtin University of Technology and John Wiley & Sons, Ltd.
Novel polymer blends from polyester and bio‐based cellulose ester
Authors: Wang Dong , Sun Gang 
Published: August 2010

AbstractA strategy to reduce the dependence on petroleum‐based building blocks and the disposal concerns of solid wastes was proposed by developing a novel polymer blend from bio‐based cellulose acetate butyrate (CAB) and poly(trimethylene terephthalate) (PTT). The thermodynamic immiscibility and the thermal behaviors of the polymer melt blends were investigated. The interfacial properties were analyzed to provide the theoretical guidance to improve the compatibility of blends. A reactive compatibilizer, poly(trimethylene terephthalate)‐graft‐(maleic anhydride) (PTT‐g‐MA) was prepared from melt reaction and characterized with FTIR. The compatibilizer was melt blended into the CAB and PTT blends. The effects of different compatibilizers on the phase morphologies and mechanical properties of blends were characterized and the interfacial interactions were studied. © 2010 Wiley Periodicals, Inc.

Rice straw fiber reinforced high density polyethylene composite: Effect of coupled compatibilizating and toughening treatment
Authors: Yao Fei , Wu Qinglin , Liu Hongzhi , Lei Yong , Zhou Dingguo 
Published: August 2010

AbstractIn this study, rice‐straw (RS) filled high density polyethylene (HDPE) composites were manufactured by extrusion and injection molding. Three compatibilizers, which are unfunctionalized ethylene/propylene copolymer (uEPR), maleic anhydride grafted EPR (EPR‐g‐MA) and PE‐g‐MA, and their combinations were introduced to strengthen fiber‐matrix interphase. The mechanical and morphological properties of composites were investigated. For single‐compatibilizer system, PE‐g‐MA or EPR‐g‐MA alone enhanced tensile, flexural, and impact strengths of resultant composites compared with HDPE/RS system without compatibilizers. Different toughening origins of individual compatibilizer were discussed based on composites' interphase morphologies and mechanical properties. For combined‐compatibilizers system, the PE‐g‐MA/EPR weight ratio is important for several properties of composites. The optimum ratio was considered as 2 : 1 and 1 : 1 for PE‐g‐MA/uEPR and PE‐g‐MA/EPR‐g‐MA modified composites, respectively. Also, composites modified by combined PE‐g‐MA/EPR‐g‐MA showed better impact strength than that modified by PE‐g‐MA alone. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011

Published: August 2010

AbstractA novel material was prepared through the blending of an unsaturated polyester resin/styrene mix with tung oil, which offered improved impact strength, creep resistance, modulus, and hardness. A nanoindentation technique was used to investigate the mechanical properties. With the incorporation of 1 wt % tung oil into the unsaturated polyester matrix, the impact strength, modulus, and hardness increased by 15, 20, and 41%, respectively. The impact‐fractured surfaces were examined with scanning electron microscopy. The dynamic mechanical analysis was performed with a nanoindentation technique. The storage and loss modulus values were determined under cyclic loading as a function of indentation. The flexural properties also significantly increased with the incorporation of tung oil. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
Supercritical fluid‐assisted electroless metal plating onto aramid films: The influence of thermal treatment
Authors: Belmas Magali , Tabata Isao , Hisada Kenji , Hori Teruo 
Published: August 2010

AbstractAlthough the production of electro‐conductive aramid fibers is efficient, the method needs to be modified before it can be applied to aramid films. Whereas impregnation of an aramid film with a metal complex using supercritical CO2 is achievable, the relatively low adhesion strength of the metal layer applied using electroless copper plating is problematic. To solve this problem, thermal treatment was conducted before, after, or both before and after electroless plating. The rationale for using thermal treatment to improve the adhesiveness of the plated layer was based on the findings that (1) an aramid film contains a significant amount of water (about 3.5 % w.o.f.), which might have a negative impact on adhesion; and (2) because an impregnated metal complex liberates metal catalyst by thermal decomposition during impregnation, a supplementary thermal action might liberate more catalyst and thereby improve adhesion. We found that thermal treatment improved adhesion of the metal layer to the aramid film. Moreover, we discovered that with respect to electroless copper plating, a short time‐lag was crucial to obtaining a thin and homogeneous metal layer with strong adhesion. In addition, we demonstrate the affinity of an aramid film for Pd(acac)2. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011

AbstractA series of 2‐phenoxynicotinic acid hydrazides were synthesized and evaluated for their analgesic and anti‐inflammatory activities. Several compounds having an unsubstituted phenyl/4‐pyridyl or C‐4 methoxy substituent on the terminal phenyl ring showed moderate to high analgesic or anti‐inflammatory activity in comparison to mefenamic acid as the reference drug. The compounds with highest anti‐inflammatory activity were subjected to in vitro COX‐1/COX‐2 inhibition assays and showed moderate to good COX‐1 and weak COX‐2 inhibition activities.
Giovanni Filippo Ingrassia: A five‐hundred year‐long lesson
Authors: Cappello Francesco , Gerbino Aldo , Zummo Giovanni 
Published: August 2010

AbstractGiovanni Filippo Ingrassia was born five centuries ago in Regalbuto, a small town in the center of Sicily. After his medical course in Padua, under the guidance of Vesalius and Fallopius, he gained international fame as a physician and was recruited as a Professor of human anatomy in Naples and later in Palermo. He is remembered as “the new Galen” or “the Sicilian Hippocrates.” He contributed to the knowledge of human anatomy through the description of single bones rather than the whole skeleton. In particular, he was the first to describe the “stapes,” the “lesser wings of the sphenoid” and various other structures in the head (probably the pharyngotympanic tube) as well as in the reproductive system (corpora cavernosa and seminal vesicles). He was also a pioneer in the study of forensic medicine, hygiene, surgical pathology, and teratology. As Protomedicus of Sicily, he developed the scientific culture in this country. During those years, he faced the spread of malaria and plague with competence and authoritativeness. Indeed, he was one of the first physicians to suppose that certain diseases could be transmitted between individuals, therefore, introducing revolutionary measures of prevention. He is remembered for his intellectual authority and honesty. Five‐hundred years after his birth, his teaching is still alive. In this article, we survey the life and contribution of this pioneer of early anatomical study. Clin. Anat. 23:743–749, 2010. © 2010 Wiley‐Liss, Inc.
Formal Synthesis of the Anti‐Angiogenic Polyketide (−)‐Borrelidin under Asymmetric Catalytic Control
Authors: Madduri Ashoka V. R. , Minnaard Adriaan J. 
Published: August 2010

AbstractBorrelidin (1) is a polyketide that possesses extremely potent anti‐angiogenesis activity. This paper describes its formal total synthesis by the most efficient route to date. This modular approach takes optimal benefit of asymmetric catalysis and permits the synthesis of analogues; in addition, the high yields and selectivities obtained eliminate the need for separation of stereoisomers. The upper half of borrelidin has been accessed by iterative copper‐catalysed asymmetric conjugate addition of methylmagnesium bromide, whereas synthesis of the lower half of the molecule was achieved by relying on asymmetric hydrogenation and cross‐methathesis as key steps.
Modulation of the Aerobic Oxidative Polymerization in Phenylazomethine Dendrimers Assembling Copper Complexes
Authors: Imaoka Takane , Kawana Yuki , Tsuji Masahiro , Yamamoto Kimihisa 
Published: August 2010

AbstractThe aerobic oxidative polymerization of phenol derivatives can provide poly(phenylene oxide)s, which are known as engineering plastics. This oxidation can be carried out with atmospheric oxygen molecules as the oxidizing reagent in the presence of copper complexes as the catalyst; however, stoichiometric or excess amounts of bases are also generally required. By using a phenylazomethine dendrimer complexed with several equivalent amounts of copper chloride, the additive (base)‐free polymerization of 2,6‐difluorophenol was successful with a very small amount of the catalyst (0.7 mol % of copper for the monomer) because the dendrimer was composed of many Schiff base units, affording a base and catalyst (copper complex) condensed reaction field. The resulting polymer was nearly linear and the molecular weight was very high. When the equimolar amount of the copper complex in one dendrimer molecule was increased, the polymer obtained under this reaction condition was rather branched, resulting in a higher glass transition temperature.
