Due to the benefits of hydrogen fuel, such as its high calorific value and flame velocity, it can be used in a dual-fuel mode of operation with diesel. The experiment was carried out for various engine loads with engine speed maintained constant at 1500. By using a digital volume flow metre, hydrogen was injected at three different volume flow rates, namely 3, 6, and 9 lpm. Engine combustion, emission, and performance parameters were evaluated for different hydrogen flow rates and compared to sole diesel. The result revealed that the brake thermal efficiency of the engine increased, whereas the brake-specific fuel consumption decreased due to hydrogen enrichment. The hydrocarbon and carbon monoxide emissions were lower in dual fuel mode when compared to sole diesel operation under all load situations. On the other hand, Oxides of Nitrogen (NOx) emission increased with hydrogen flow rate and resulted in higher NOx than diesel. Furthermore, hydrogen enrichment increased the values of the peak heat release rate and cylinder pressure by a significant margin from the corresponding values given by diesel fuel.

The investigation advocates a change in the electronic bandgap of ZnONT on the respective substitution of Zn with Na, Mg, and Al. The forbidden energy gap vanishes on Na incorporation, while Al substitution brings the gap to 0.08eV. The formation energy calculations suggest the feasibility of these metallic substitutions, of which Na incorporation is most favorable. Partial density of state (PDOS) analysis is well correlated with band structures. A localized state above the Fermi level contributed from Al-3p in Al-ZnONT suggests the electronic affinity of Al-ZnONT for incoming nucleophiles. Our optical investigation shows large ε1(ω) values in far-infrared (IR) and visible (Vis) regions for M-ZnONT. Hence, suggests a high refractive index for the metal-substituted ZnONTs in the prescribed range. The study suggests that photonic energy loss due to attenuation, bending, and absorption are weak in ultra-violet (UV) and far UV regions i.e, (3eV to 8eV).

Among various energy storage devices such as fuel cells, batteries, capacitors, supercapacitors, flywheels, etc., it is the supercapacitor device that has elicited extensive research interest recently because of prominent features like high power density, fast recharge capability, and long cycle life. The main objective of this article is to review the enhancement of the electrochemical performance of supercapacitor devices. The electrochemical properties of the supercapacitor device majorly depend on the electrode materials used, which include carbonaceous materials, metal oxides, and conducting polymers. In order to reduce energy shortages and environmental pressure, carbon materials derived from biomass/waste materials have been considered remarkable candidates for electrode materials with the advantages of high abundance, low cost, and environmental friendliness. This review shows the complied study of various methodologies for the preparation of activated carbons derived from different biomass residues such as plants, animals, and microorganisms, which have been investigated in the past few years as electrochemical electrode materials for supercapacitors.
