The cakes were characterized for proximate, ultimate and ligno-cellulosic compositions using ASTM and TAPPI standard methods. All studies were conducted at high temperature and pressure in a semi-batch autoclave. Highest conversion with maximum biocrude yield (∼35.3%) was obtained with P. pinnata cake. Silica adsorption chromatography result showed higher oxygenated aromatics subfraction in both Tung biocrude and Jatropha biocrude. GC/MS qualitative analysis confirmed the presence of heavy, oxygenated/ nitrogenous and poly aromatic hydrocarbons with carbon number ranging from C 5 -C 47 in the biocrude. The viscosity, pH, density, total acidic number (TAN) and water content of biocrudes were evaluated using various standard methods. 34.2 to 45.8% increases in the calorific value is observed for biomass to biocrude. Biochar obtained were characterized using proximate and ultimate analysis and SEM, TGA techniques. Higher calorific values (24.7–26.3 MJ/kg) of all the biochar make them suitable for their potential application as briquettes in the furnace for power generation.

Five major tasks were involved: definition of the system boundary; estimation of energy benefits; estimation of carbon sequestration; estimation of energy costs; estimation of carbon emissions. Calculation of overall energy and carbon budgets required a set of ‘standard’ assumptions about practices and resultant energy inputs to be made. These standard assumptions accounted for all activities involved in production and delivery of biofuel within the immediate vicinity of the farm ( 3.2 km ). The energy ratio, that is the ratio of energy produced to energy consumed by the biofuel producing system, was estimated to be much greater than 1, typically around 30. This energy ratio proved to be very sensitive to assumptions about crop management and wood processing, as well as associated energy inputs, varying from 20 to 64 when model input assumptions were varied between extremes. The carbon emissions coefficient exhibited similar sensitivity to input assumptions. The gross non-renewable energy requirement, that is the total consumption of non-renewable energy associated with the direct consumption of 1 MJ of energy in the form of wood fuel, was estimated to be 0.035 MJ MJ −1 . The carbon emissions coefficient, that is the carbon emitted in producing 1 MJ of energy in the form of wood from short rotation coppice, was estimated to be 0.0013 kgC MJ −1 . Further research is needed to validate input assumptions and to estimate budgets for complete, practical, energy generation systems.

Lalit Kumar in OpenAIREThis paper presents Gravitational search algorithm (GSA) optimization techniques for the optimal location of Flexible AC Transmission System (FACTS) devices in the power system network to attain minimum transmission active power loss, the optimal value of control variables, and optimal bus voltage. These proposed methods are legitimate in the IEEE-30 test bus system. Here, the proposed GSA algorithm is adapted for minimization of active power losses and it is also improving bus voltage. After using facts devices, from the obtained results power system loadability improved within range and at different loading condition in the power system networks all generators capable to dispatch a significant amount of active power. By incorporating facts devices, we proposed active power loss reduced and also maintained the bus voltage of the power system network at different loading condition. Hence, for Loadability enhancement in the power system, this gives a better optimal solution.

ElHag;Abstract The paper presents a comparative study of the effect of porous layer parameters on the thermal performance of capillary-assisted evaporators. The results show that there are optimum particle sizes that are associated with maximum boiling heat rates and heat transfer coefficients. The results also show that the layer thickness has monotonic effect on the evaporators’ performance but its impact is less pronounced compared to that of the particle size. The trends are explained in terms of the contradicting effects that exist within the layer. Agreement in trend, and to a lesser degree in value, is obtained between the analytical and experimental results with the discrepancy explained in terms of the inaccuracies of the empirical formulae used and the effect of condensation on the tube wall thermal resistance. Boiling heat transfer coefficients of up to 5 kW/m2 °C were achieved.

Abstract A photoelectrochemical solar cell from camphoric p-carbon semiconducting pellet has been developed for the first time from the soot of a natural source, camphor. This semiconducting camphoric carbon is unusually stable both in acidic and alkaline media. Preliminary findings show that the semiconductor has band gaps ( E g 2.28 eV direct and 1.28 eV indirect ) suitable for solar energy conversion. PEC properties are also being discussed.

Catalão, João P. S. in OpenAIRENowadays, the operation of the smart distribution system (SDS) is more complicated with the penetration of electric vehicles (EVs), due to EVs’ uncertainties as well as the capability of vehicle-to-grid (V2G). On the other hand, distribution transformers (DTs) which have to meet the demand of EVs are one of the essential components of SDS; indeed, their failure can lead to irreparable damage. The cause of most of these failures is overloading and high ambient temperature. The overloading increases the temperature of the various parts of the DTs, especially hot spot temperature (HST). Increasing this temperature reduces the nominal life of the DTs. With a high number of EVs in the future, and as a consequence high energy demand which has not been taken into account in proper operating program, it could lead to the overloading of DTs. So, in this paper, the loss of life (LOL) of a DT that feeds the residential loads and an EV parking lot (EV PL) is investigated. The maximization of the profit of the distribution system operator (DSO) is considered in two different parts i.e. with/without the appropriate operation coefficient (OC) of DT. Also, two different scenarios are applied i.e. charging mode (CM) of EVs and charging/discharging mode (CDM) of EVs. The results show that if the OC is not properly considered, the LOL of the transformers will be significantly high, implying a higher total ownership cost.

In this study, anthraquinone-2-sulfonic acid (AQS), an electron transfer mediator, was immobilized onto graphite felt surface via spontaneous reduction of the in situ generated AQS diazonium cations. Cyclic voltammetry (CV) and energy dispersive spectrometry (EDS) characterizations of AQS modified graphite demonstrated that AQS was covalently grafted onto the graphite surface. The modified graphite, with a surface AQS concentration of 5.37 ± 1.15 × 10(-9)mol/cm(2), exhibited good electrochemical activity and high stability. The midpoint potential of the modified graphite was about -0.248 V (vs. normal hydrogen electrode, NHE), indicating that electrons could be easily transferred from NADH in bacteria to the electrode. AQS modified anode in MFCs increased the maximum power density from 967 ± 33 mW/m(2) to 1872 ± 42 mW/m(2). These results demonstrated that covalently modified AQS functioned as an electron transfer mediator to facilitate extracellular electron transfer from bacteria to electrode and significantly enhanced the power production in MFCs.

Md Tabish Noori in OpenAIREAbstract Efficient energy utilization of traction device includes maximization of energy efficiency indices (i.e. pulling ability and tractive power efficiency) with optimum slip range. The present study compares the performance of 13.6 × 28 bias and radial-ply tyres (T1 and T2) used in agricultural tractors under controlled soil bin conditions. With a view to reduce the wheel slippage, the test was conducted under varying mode of ballast loads using either iron or water including the base weight (1050 kg). The combination of load and inflation pressure was selected to achieve 20% deflection and performance test was conducted in soft (450 ± 50 kPa), medium (1150 ± 50 kPa) and hard soil (1750 ± 50 kPa) conditions. The average pulling ability and tractive power efficiency of the test tyres in case of iron ballast was found to be 2–7.5% and 0.5–8.89%, respectively, which was better than the corresponding liquid ballast. It was also observed that the maximum power output can be increased by the help of ballasting, the output power was found to be more in case of corresponding weight of 50 and 75% equivalent weight of iron ballast compared to liquid ballast.

Here, we investigate the incident photon density dependent bandedge bleaching and HCs dynamics in thin film methyl-ammonium lead iodide-chloride (mixed halide) perovskite using transient absorption spectroscopy. The bandedge bleaching dynamics shows the radiative recombination rate constant of the order of ∼10−11 cm−3 s−1 results in the maximum carrier diffusion length of the order of ∼10 μm. The HCs dynamics indicates cooling occurs by longitudinal-optical (LO) phonon emission in early ∼800 fs via Frohlich electron–phonon interaction at low-carrier concentration (∼1.7 × 1018 cm−3) and an efficient phonon bottleneck due to the delayed LO-phonon decay by two order of magnitude about ∼11 ± 1.3 ps at high carrier density (∼1019 cm−3). Our finding shows the potential of thin film mixed halide perovskite in HCs photovoltaic and light emission application.
