Abstract:
Hydrothiolation of bromoalkynes has been reported for the first time under metal catalysed conditions. Indium(iii) trifluoromethanesulfonate was demonstrated as the first catalyst which can catalyse the hydrothiolation of bromoalkynes with absolute regio- and stereoselectivity to generate synthetically valuable (Z)-β-bromo vinyl sulfides in good yields.

Abstract:
Horseradish peroxidase catalyses the oxidation of NAD dimers, (NAD)2, to NAD+ in accordance with a reaction that is pH-dependent and requires 1 mol of O2 per 2 mol of (NAD)2. Horseradish peroxidase also catalyses the peroxidation of (NAD)2 to NAD+. In contrast, bacterial NADH peroxidase does not catalyse the peroxidation or the oxidation of (NAD)2. A free-radical mechanism is proposed for both horseradish-peroxidase-catalysed oxidation and peroxidation of (NAD)2.

N-alkylated C2-symmetric amino acid amide derivatives were shown to catalyse the Michael addition of 2-hydroxy-1,4-napthoquinone to β-nitrostyrene, achieving a maximum ee of 44%. The corresponding trifluoroacetic acid salts also catalysed the aldol reaction between 4-nitrobenzaldehyde and hydroxyacetone, leading to the formation of predominantly syn-aldol products in up to 55% ee. Aspects of the solvent dependence of the aldol reaction and the H-bonding of the catalyst were investigated.

Abstract:
HACN (homoaconitase) is a member of a family of [4Fe-4S] cluster-dependent enzymes that catalyse hydration/dehydration reactions. The best characterized example of this family is the ubiquitous ACN (aconitase), which catalyses the dehydration of citrate to cis-aconitate, and the subsequent hydration of cis-aconitate to isocitrate. HACN is an enzyme from the α-aminoadipate pathway of lysine biosynthesis, and has been identified in higher fungi and several archaea and one thermophilic species of bacteria, Thermus thermophilus. HACN catalyses the hydration of cis-homoaconitate to (2R,3S)-homoisoc

The 5,10-methenyltetrahydrofolate (5,10-CH=H4folate) synthetase catalyses the physiologically irreversible formation of 5,10-CH=H4folate from 5-formyltetrahydrofolate (5-HCO-H4folate) and ATP. It is not clear how (or if) 5-HCO-H4folate is formed in vivo. Using a spectrophotometric assay for 5-HCO-H4folate, human recombinant 5,10-CH=H4folate cyclohydrolase, which catalyses the hydrolysis of 5,10-CH=H4folate to 10-HCO-H4folate, was previously shown to catalyse inefficiently the formation of 5-HCO-H4folate at pH 7.3 [Pelletier and MacKenzie (1996) Bioorg.

Abstract:
‘Making things happen—catalysis’ examines chemical catalysis, considering what makes a reaction go or not go and how enzymes catalyse particular chemical reactions. This process is not unique to living systems, although enzymes are both more potent and more selective than catalysts encountered elsewhere in chemistry. A catalyst is an agent that speeds up a chemical reaction but remains unchanged itself at the end of the process. Since a catalyst is not altered or used up, it can be used over and over again.

This chapter focuses on the catalysis of organic reactions in solution by small molecules and ions. Catalysis is the enhancement of the rate of a reaction by a compound (the catalyst) not generally present in the chemical equation which describes the reaction. Normally, a catalyst remains unchanged by the chemical reaction it catalyzes. It brings about the rate enhancement by providing a reaction pathway additional to the one which occurs in its absence. This additional pathway will have its own rate law, and the total rate of reaction in the presence of the catalyst is the sum of the catalyse

Due to their acid characteristics and pore structure, which can induce high product selectivity; zeolite catalysts are used extensively in industry to catalyse reactions involving hydrocarbons. However, these catalysts can suffer from deactivation due to cracking reactions that result in the deposition of carbon leading to poisoning of the acid sites and blocking of the pores [1]. Depending upon the reaction and the particular catalyst involved this deactivation may take place over several months or even years but in some cases occurs in minutes.

Abstract:
Studies have shown that dermatan sulfate (DS), heparan sulfate (HS) and chondroitin-4-sulfate (C4S), have antithrombotic properties. The sulfate to carboxylate ratios of these three glycosaminoglycans (GAGs) are approximately half that of heparin (HEP) and the gravimetric dose of each of the three GAGs required to achieve antithrombotic effects in vivo comparable to HEP can be 10 times or more than that of HEPT Since antithrombotic effects depend on the ability of a GAG to catalyse thrombin inhibition and/or to inhibit prothrombin activation, we determined the relationship between the extent o

Abstract:
The authors adopt a geopolitical lens to better understand policy responses to food insecurities under reversal of global integration and weakening multilateralism. They specifically focus on transboundary climate risks to food production and trade: how climate impacts on agriculture can generate cascading effects through international trade and global supply chains to catalyse risks to countries worldwide.

Full text
Abstract:
Oxidation catalysts are often utilized to reduce carbon monoxide, formaldehyde, and volatile organic compounds in order to meet emissions regulations for large bore natural gas engines. These catalysts degrade over time and need to be replaced or regenerated to maintain emissions compliance. This work evaluates the effectiveness of catalyst regeneration, or catalyst washing. The evaluation is performed by utilizing field and laboratory slip streams combined with catalyst module performance (reduction efficiency) measurements and catalyst material surface analysis to quantify catalyst poisons.

Full text
Abstract:
Oxidation catalysts and three-way catalysts can be used to reduce the amount of CO present in engine exhaust. For 2-stroke lean-burn engines, the oxidation catalyst degrades over time be-cause of the buildup of poisons such as sulfur, zinc, phosphorous, and calcium. Three-way cata-lysts used with stoichiometric engines also degrade over time. Emissions analyzers are often used to evaluate the degradation of oxidation catalysts and three-way catalysts, but it can be very time consuming and expensive. Ideally, a simple sensor system would be beneficial for operating companies to determine if the

Abstract:
Two-way catalysts or oxidation catalysts are the common after-treatment systems used on lean burn natural gas engines to reduce CO, VOCs and formaldehyde emissions. The study evaluates the performance of oxidation catalysts from commercial vendors for varying catalyst temperature and space velocity. For this study, a part of the exhaust from a Waukesha VGF-18 GL lean burn natural gas engine was flowed through a catalyst slipstream system to assess the performance of the oxidation catalysts. The slipstream is used to reduce the size of the catalysts and to allow precise control of temperature a

Abstract:
This brief discusses the opportunities linked to using a life-course approach to devise policies to foster sustainable consumption. It considers the potential of life-course transitions to catalyse shifts towards more sustainable consumption. It draws on a study conducted among older adults in Bangkok about their transportation choices and experiences. The work that underpins the brief is part of a wider effort to explore related issues of consumption, lifestyles, and ageing in a low-middle-income setting, and to understand the role that transportation systems can play.

Abstract:
Oxidation catalysts are effective at reducing CO, formaldehyde, and VOCs as long as the catalyst temperature is above the light-off temperature for each species. It is important to understand the effects of temperature and space velocity on regulated species in order to effectively apply oxidation catalyst technology to lean burn engines, in particular 2-stroke engines that typically have lower exhaust temperatures. Various catalysts were tested on an exhaust slipstream coupled to a 4-stroke lean-burn engine which allows tests to be conducted at different temperatures and flow rates. The effec

Abstract:
This research was to study the photocatalytic activity of three different metal oxide catalysts, namely MCM-41, TS-1, and bismuth titanate (Bi[subscript 12]TiO[subscript 20]) in the reactive black 5 dye solution and the waste water obtained from a dye industry. These catalysts were synthesized using silatrane, titanium glycolate and bismuth nitrate precursors. The degradation process was first studied in the reactive black 5 dye model. The parameters in this study were pH, amounts of H[subscript 2]O[subscript 2] and Ti-loading in zeolite structure while fixing the organic dye at 40 ppm. At pH3
