The scramjet engine is an air-breathing engine that can be used to travel at supersonic speeds. Research is being done into how these engines can be used as reusable launch vehicles for space travel, missile propulsion, and many hope one day scramjets can be used for commercial flight. Scramjets are highly beneficial in the sense that hydrogen is the primary fuel and that manufacturing is simple c
As Sweden advances toward large-scale hydrogen production for industrial applications, low-grade waste heat (≈80 °C) from electrolyzers becomes available. A proposed solution is to integrate this heat between the two condensers in a combined heat and power plant. This can be done with different configurations, which were setup and studied. At full load, introducing 15 MW of heat increased electric
Inner-sphere reorganization energies have been calculated for a number of models of six-coordinate iron porphyrins (with varying axial ligands), using the density functional B3LYP method. If the axial ligands are uncharged, the reorganization energy is very low, 5-9 kJ/mol. If one of the axial ligands is charged, the reorganization energy is higher, 20-47 kJ/mol, but such sites are normally not us
Hydropower energy is one of most promising clean energy technologies, however this energy technologies has many challenges if compere other renewable energy for example Biomass, solar, wind energy, has high capital investment cost. In Mozambique, access to conversional energy in form of electricity has been limited to most of the rural population. The objective of this investigation research is to
Energy metabolism, including alterations in energy intake and expenditure, is closely related to aging and longevity. Metabolomics studies have recently unraveled changes in metabolite composition in plasma and tissues during aging and have provided critical information to elucidate the molecular basis of the aging process. However, the metabolic changes in tissues responsible for food intake and
The emergence of sixth-generation (6G) networks has spurred the development of novel testbeds, including sub-THz networks, cell-free systems, and 6G simulators. To maximize the benefits of these systems, it is crucial to make the generated data publicly available and easily reusable by others. Although data sharing has become a common practice, a lack of standardization hinders data accessibility
The focus of the research in the Membrane Group at Lund University is on the integration and optimization of membrane processes for the food, biotech, pulp and paper industry as well as water and wastewater treatment plus fouling and cleaning of membranes. The Membrane Group's primary emphasis lies in the water-energy-food nexus, establishing a strong connection to the UN's global sustainability g

The electric and magnetic polarizabilities of the proton are now well known, owing to Compton scattering measurements on hydrogen targets; however, the neutron polarizabilities are still relatively uncertain, compared to the proton values. To address this problem, a multiinstitutional collaboration has conducted a program of elastic Compton scattering experiments on deuterium at the MAX IV Laborat
Because biomass is a widely available, renewable resource, its utilisation for the production of energy has great potential for reducing CO2 emissions and thereby preventing global warming. In this mini-review the `state of the art' of several fermentation processes is discussed, starting with the most advanced process of ethanol production. This is followed by methane production, an established p
The impact of different spark designs on the ignition and combustion stability is studied using a 13-liter CNG fueled heavy duty spark ignited engine to search for the “optimal” spark design. Experimental results show that robust ignition can be achieved using a significantly shorter spark duration and lower energy than expected. A capacitive discharge ignition (CDI) system enabled to separately

The residential sector presents one of the most pressing decarbonisation challenges, especially within historically gas-dependent nations such as the UK. Compounding this challenge, issues of social acceptance have slowed efforts to advance the residential decarbonisation agenda in the UK context. To date, existing technologies such as heat pumps and smart meters, as well as emerging technologies
The double sided silicon strip detector (DSSSD) is a segmented silicon detector commonly used in the fields of high energy physics and nuclear physics. This type of detector is used for analysis of reactions produced by charged particles. This makes it well suited for a number of analytical methods commonly used in ion beam analysis (IBA), such as Rutherford Backscattering (RBS) and elastic recoil
Emissions and fuel economy are evaluated for two types of biofuels, namely 2-phenyl ethanol and cyclohexaneethanol. Both are derived from lignin, a form of lignocellulosic biomass. The former and latter oxygenates have an aromatic and aliphatic (i.e. saturated) ring structure, respectively. Two parametric engine sweeps were performed. First, non-EGR operation by means of varying the load via injec
Combination of right EGR rates with turbocharging has been identified as a promising way to increase the maximum load and efficiency of heavy duty spark-ignited natural gas engines. With stoichiometric conditions a three way catalyst can be used which means that regulated emissions can be kept at very low levels. However dilution limit is limited in these types of engines because of the lower burnCombination of right EGR rates with turbocharging has been identified as a promising way to increase the maximum load and efficiency of heavy duty spark-ignited natural gas engines.

This paper examines the potential of using ammonia (NH 3) as a primary fuel in heavy-duty engines for decarbonization, with some challenges yet to be addressed. It presents a numerical study of a Reactivity Controlled Compression Ignition engine, where pilot diesel is used to ignite the premixed ammonia/air mixture. The numerical model and combustion mechanism are validated against engine experime
