Multi-metallic Pd@FePt core–shell nanoparticles were synthesized using a direct seed-mediated growth method, consisting of facile and mild procedures, to increase yield. The Fe/Pt ratio in the shell was easily controlled by adjusting amount Fe Pt precursors. Furthermore, compared with commercial Pt/C catalysts, exhibited excellent activity stability toward methanol oxidation reaction (MOR), mak...

The complementary blending of cold-pressed meadowfoam seed oil methyl esters (MFME) with soybean and waste cooking oil methyl esters (SME and WCME) was investigated. MFME prepared from cold-pressed meadowfoam oil exhibited an exceptionally high induction period (IP) of 66.2 h whereas SME and WCME yielded considerably lower values of 5.9 and 4.5 h, respectively. The kinematic viscosities (KVs) o...

This study reports the conversion of Jatropha curcas oil to biodiesel catalyzed by sulphated zirconia loaded on an alumina catalyst using response surface methodology (RSM). Specifically, it studies the effect of interaction between process variables on the yield of biodiesel. Jatropha is found to be survived in different locations in South-East Asia. Jatropha oil is favoured to palm oil for it...

Changes in climate and land use that interact synergistically to increase fire frequencies and intensities in tropical regions are predicted to drive forests to new grass-dominated stable states. To reveal the mechanisms for such a transition, we established 50 ha plots in a transitional forest in the southwestern Brazilian Amazon to different fire treatments (unburned, burned annually (B1yr) o...

<p>This research examines the scope for reducing air pollution caused by transportation sector through infusion of biofuel and antioxidants ensuring partial replacement conventional fuel. A four-stroke, direct-injection, multi-cylinder constant-speed diesel engine was employed experimental analysis. The ternary fuel blend with a composition 70% fuel, 20% rubber seed oil 10% pentanol sea w...

Maintenance of vegetation is a central goal of watershed management. When prescribed burning of chaparral is included in management practice, then it is important for managers to understand and use the natural chaparral fire regime to maximize vegetation response. Variations from the natural fire regime in intensity, frequency, season, and environmental conditions at the time of burning can all...

In this study, tomato seed oil was used to produce Biodiesel fuel. To reduce the percentage of free fatty acids, the oil was reacted at a temperature of 40, 50, and 60°C with a mixture of sulphuric acid and the industrial methanol with different molar ratios of oil. The best conversion efficiency was achieved at 60°C and a molar ratio of 1:9. In the transesterification step, biodiesel was produ...

The transition to alternative fuels and vehicles presents many challenges that require long-range strategic thought and planning. Fuel producers must make expensive infrastructure decisions about which fuels to support years before they are sold. Vehicle producers must commit to new drivetrains on a similar long-range schedule. Whichever technologies prevail, hydrogen fuel cell, PHEV, BEV or bi...

Bark beetles, fuels and future fire hazard in contrasting conifer forests of Greater Yellowstone" (2013). ABSTRACT The extent and severity of bark beetle (Curculionidae: Scolytinae) epidemics and the frequency of large, severe fires have reached unprecedented levels in recent decades, and these trends are expected to continue with ongoing climate change. Insects and fire have tremendous ecologi...

Conversion of nongrain biomass into liquid fuel is a sustainable approach to energy demands as global population increases. Previously, we showed that iron can act as a catalyst to enhance the degradation of lignocellulosic biomass for biofuel production. However, direct addition of iron catalysts to biomass pretreatment is diffusion-limited, would increase the cost and complexity of biorefiner...
