Ebook "Biocompatible graphene for bioanalytical applications" highlights the latest advances in the use of graphene and bio-compatible-material-decorated graphene to detect various targets (e.g. DNA, RNA, amino acids, peptides, proteins, enzymes, antigens, glucose, DA, AA, UA, ATP, NADH, gas, ions, etc.). It focuses on the specific interaction of these substances with graphene (or modified graphene) and the efficient transduction of the target recognition event into detectable signals via various techniques.

The thesis " A Study of Vibration Control of Truck Seat Suspension System" has designed a novel active truck seat suspension system for a further study of active vibration control. A 5-degree-of-freedom driver and seating suspension system model for active vibration control has been developed. A novel fast system parameter identification method from vibration measurement data has been proposed for the seat-occupant system based on the multi-objective Genetic Algorithm optimization (GA).

Low-cost activated carbon (AC) samples obtained from waste coffee grounds were used for CO2 and CH4 adsorption. ACs were prepared by chemical activation and carbonized at three different temperatures. AC carbonized at 800◦C showed a relatively high surface area (582.92 m2 g−1) and high adsorption capacities of 2.6 mmol g−1 and 1.1 mmol g−1 at 25◦C for CO2 and CH4, respectively. Adsorbent samples were prepared by loading of Fe3+ metal ions onto ACs and their adsorption capacities were compared with those of nonloaded ACs.

The study revealed that the pH of cow-dung slurry at the beginning was 7.8; neem-cake, 5.0 and pongamia-cake, 5.8 suggesting significant differences in pH among the bio-gas substrates used. Two months after anaerobicdigestion, there was increase in pH with increase in the proportion of cow-dung and also increase in total-N and P in biogas spent slurry after anaerobic-digestion. There was no definite trend with reference to total-K.

The bio-gas produced from food waste, decomposable organic material and kitchen waste, consisting of methane and a little amount of carbon di oxide is an alternative fuel for cooking gas (LPG). Also, the waste materials can be disposed off efficiently without any odor or flies and the digested slurry from the bio-gas unit can be used as organic manure in the garden.

The bio-recovery of three different oil-polluted tropical soils – RS (oil-polluted soil sample from River state), LS (soil sample from NNPC depot, Lagos) and POS (oil-polluted soil sample from Oriade L.G.A., Lagos) by manure amendment was studied for eight weeks. The rates of crude oil biodegradation after manure application as quantified by Gas chromatographic analysis of residual total petroleum hydrocarbon (TPH) showed the same trend of decrease in the total petroleum hydrocarbons in both the LS and RS series.

10 isolates of Trichoderma asperellum was used for characterization of secondary metabolites through gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) analysis to establish valid correlation between the production of antifungal metabolites and their bio-efficacy as BCAs. The investigation revealed that the culture filtrate of T. asperellum isolates were showed the presence of 673 secondary metabolites at different retention time with a range of 39 (Ta20) to 101 (Ta-12) with GC-MS.

Straw burning after harvesting is a current environmental issue causing loss of nutrient to soil and many hazardous effects to the environment. To overcome the problem of straw burning is Bio-CNG generation from agrowaste. Converting stubble into energy is an innovative way to address the matter as it helps to reduce the greenhouse effect and fight against the threats of global warming.

An experiment was conducted to evaluate the direct effect of different level of sulphur (S) alone or in combination with organic manures on mustard in calcareous soil of north India. Sulphur application significantly increased the S concentration and its uptake by mustard (seed+stover). The optimum level of S was found to be 60 kg S ha-1 in conjoint with 5 t Bio Gas Slurry (BGS) ha-1 for mustard crop with respect to concentration and nutrient uptake.

In an endeavour of exploring alternative energy sources to petroleum based fuels, bioethanol (ethanol derived from biomass) is considered as the most promising renewable fuel because of its potential to cut greenhouse gas emissions by 86% and higher octane (ability to resist compression) rating than gasoline. Present investigation was aimed at bioconversion of paddy straw to ethanol using partially purified fungal cellulases. A variety of soil samples were tested for the presence of cellulolytic fungal strains using enrichment culture technique.

Production of biofuels, especially bio-ethanol from lignocellulosic biomass, holds remarkable potential to meet the current energy demand as well as to mitigate greenhouse gas emissions for a sustainable clean environment. Rice is one of the most important agricultural crops in India. Rice straw is an important residue which is generated in large amount in India. Every kilogram of grain harvesting is accompanied by the production of rice straw to a tune of 1.0–1.5 kg. Major proportion of the rice straw is burnt in the field itself.

The production of biogas from the food wastes is important to recycle it an effective way to avoid mixing of odorous gas in to the atmosphere. The biogas production potential of food waste is higher due to high organic nutrients and starch contents. This researchpaper indicate that the potential of food waste for biogas production. The combinations of kitchen food waste with different ratios of cow dung were involved for the production of biogas production. The result indicated that the treatment containing 100% kitchen food waste alone produced maximum quantity of biogas2877.
