FTIR Studies on NO Adsorption on [Co+Mg(Sr)] /ZSM-5

引用

Chemical Research in Chinese Universities 2002年第4期18卷 389-392页

作者： lee C. W. CHONG P. j. KRICT Taejon 305-606 KoreaKRICT Taejon 305-606 Korea

The adsorption of NO on /ZSM-5 zeolites with different contents was studied by means of FTIR spectroscopy. The dominant NO species adsorbed on /ZSM-5 was found to be in a dinitrosyl form, as demonstrated by the IR bands at 1 813 and 1 896 cm -1. NO was adsorbed in a mononitrosyl form as shown in the region of 1 937-1 939 cm -1 as a minor species. Samples /ZSM-5 showed a new band near 1 858 cm -1(w) attributable to the species of Co_3O_4-NO. It was found that zeolite /ZSM-5 exhibits superior performance characteristics for SCR of NO molecules, and is promising as a useful catalyst. The typical catalyst /ZSM-5 for SCR resulted from the collaboration of the metal alkalinity and the ionic radius of the metal(such as Mg or Sr).

Measuring the spatial and social characteristics of the architectural plans of aged care facilities

Frontiers of Architectural Research 2017年第4期6卷 431-441页

作者： j. Hyun lee Michael j. Ostwaid Hyunsoo lee School of Architecture and Built Environment The University of Newcastle Callaghan NSW 2308 Australia Department of Interior Architecture and Built Environment Yonsei University Seoul 03722 Republic of Korea

This paper presents a method that combines visibility graph and isovist analyses to investigate the spatia[ and social properties of architectural plans for aged care facilities. The potential of the combined method is examined by measuring the properties of three sets of plans for residential aged care facilities. The first set is a pair of hypothetical, idealized plans, which allegedly reflect the ＂best practice＂ in the industry. The second set comprises a pair of plans for recent Australian designs, and the third set is a pair of plans for South Korean facilities. Results of the computational anatysis of these six plans suggest that social and cultural factors may shape the design of aged care settings and partially explain their international differences. The application of this methodological approach contributes to the understanding of the relation- ship between spaces and their cultural and social properties in the design of aged care facitities.

Leader-following consensus control for networked multi-teleoperator systems with interval time-varying communication delays

We study the leader-following consensus stability and stabilization of networked multi-teleoperator systems with interval time-varying communication delays. With the construction of a suitable Lyapunov–Krasovskii functional and the utilization of the reciprocally convex approach, novel delay-dependent consensus stability and stabilization conditions for the systems are established in terms of linear matrix inequalities, which can easily be solved by various effective optimization algorithms. One illustrative example is given to illustrate the effectiveness of the proposed methods.

Addition of tert-butylhydroquinone(TBHQ)to maize oil reduces lipid oxidation but does not prevent reductions in serum vitamin E in nursery pigs

Background: Maize oil is abundantly used in foods and feeds and is highly susceptible to oxidation. Consequently,commercially available antioxidants should be evaluated for effectiveness against lipid oxidation in swine diets. Our study was conducted to evaluate growth performance of nursery pigs fed oxidized maize oil and to determine effects of using antioxidants on oxidative status in a 2 × 2 factorial design. Two hundred eight weaned pigs were blocked by initial BW into 13 blocks, resulting in 4 pigs per pen and 13 pens per treatment. Dietary treatments included 6% unoxidized or oxidized maize oil, and 0 or 60 mg/kg of tert-butylhydroquinone(TBHQ), which was added after lipid oxidation. Data for growth performance were collected from 5 time periods of a two-phase feeding program(Phase 1 = d 0 to 12 and Phase 2 = d 13 to 34). Serum and liver samples were collected from one pig per pen, which had initial BW closest to average BW to determine oxidative status on d ***: Oxidized maize oil was heated for 12 h at 185 °C with 12 L/min of air, yielding a peroxide value(PV) of 5.98 m Eq O2/kg and TBARS of 0.11 mg MDA eq/g. Addition of TBHQ to diets containing oxidized maize oil decreased PV by 37% and increased the oil stability index by 69%. Final BW, ADG, ADFI, and G:F of pigs were not different among the four dietary treatments. However, pigs fed oxidized maize oil tended(P < 0.08) to increase hepatosomatic index by 5% compared with those fed unoxidized oil, and this was not affected by adding *** serum vitamin E concentration of pigs fed oxidized maize oil was less(P < 0.03) than pigs fed unoxidized oil,but this reduction was not reversed by adding TBHQ. Finally, the serum and liver selenium concentration were not different among the ***: The addition of TBHQ did not affect growth performance and vitamin E status in pigs fed moderately oxidized maize oil, but TBHQ reduced lipid oxidation, enhanced the oil stability, and appeared to redu
