Methanol

hydrogen from fossil fuels is said to be a mature technology. Of the two main fossils fuels used, natural gas offers the best economics and efficiencies and is the main pathway used to generate hydrogen nowadays, mainly for the production of ammonia and methanol. The other, being coal, can also be used to produce hydrogen but the initial investment is much greater and the efficiency is lower compared to when natural gas is used. Coal can be economically favourable when compared with natural gas…

The biodiesel that never boomed The greenhouse gas emission and reduction of fossil fuel reserves has created energy insecurity and ecological imbalance in the foreseeable future. The organic extracts of fossil fuels that are used right now emit high volume of greenhouse gases which contribute to climate change. The drastic increase in consumption patterns has the capability to create a substantial energy crisis for the generations to come. In addition to this, the pollution patterns may even…

Biodiesel, an environment friendly, alternative, nontoxic, biodegradable and renewable fuel, has a great potential as a renewable fuel for CI engines. It is commonly produced by esterifying or transesterifying the vegetable oils or animal fats with methanol [9]. It can be used directly or mixed with petroleum–diesel in any proportion and directly used in engines with no need of modifications [10]. Its usage reduces greenhouse gas emissions compared to mineral diesel. Biodiesel has a relatively…

2.3. Pharmacokinetics of (S)-ketoprofen 2.3.1. Blood sampling On the day of the study, rats were cannulated approximately 30 min before uric acid injection and 3 h before the drugs were administered. The animals were anesthetized and the caudal artery was cannulated with a PE-10 cannula (Clay Adams, Parsippany, NJ, USA) connected to a PE-50 cannula. The cannula was kept patent with heparinized saline solution and stopped with a needle. Rats were allowed to recover from anesthesia and…

Hosseini 2010) (Table 1). Total fat was extracted, according to Bligh and Dyer on days 0, 4, 8, 12 and 16 of refrigerated storage (Bligh and Dyer 1959). Antioxidant evaluation of lycopene solutions by DPPH method DPPH solution in methanol (24 mg mL-1) was prepared and 2 mL of this solution were added to 50 μL of different concentrations of lycopene. After one-hour incubation at room temperature in the dark, absorbance at 517 nm was measured, using a spectrophotometer…

Introduction Tobacco use is one of the major threats to human health which kills nearly 6 million people each year with an estimated 8 million deaths in the year 2030. More than 2,500 chemicals are found in tobacco and its smoke, among which terpenoids and alkaloids are the major groups [1]. Though there is clinical uncertainty about the carcinogenic property of nicotine, evidences have proved nicotine as the main psychoactive agent responsible for the development of tobacco dependence [2, 3].…

Abstract:In today’s automobile world it is a great desirable challenge to build an engine having more power generation & less fuel consumption,which are desired parameters for the increased efficiency of the engine. For getting more power engine needs more fuel and if less fuel consumption is needed the power transmitted will be less. In conventional engines the heat energy using is 30% of produced energy and the remaining energy nearly 70% is going as waste. That means, to get more power from…

Depends on composition calorific value can vary between 25-49 KJ/Kg. Raw biogas has got comparatively less calorific value and might not seems to be a good option in automobile IC engines, though it can be used for stationary application IC engines installed near the Biogas production plant. It is the large percentage of CO2 in the raw or unpurified biogas that reduces the heating value of the gas, increases the compression and transportation costs. And as the compression and transportation are…

Under oxidative conditions, certain nucleobases (for example, adenine and cytosine) can form N-oxides. Also, the C8 position of guanosine is vulnerable to hydrolytic attack under either strongly acidic or strongly alkaline conditions. The 5,6 double bond of pyrimidine nucleosides also reacts with halogens and halohydrins to give the corresponding addition products (Shabarova and Bogdanov, 1994). Selected examples of the side reactions that occur during oligonucleotide synthesis are given below.…
