Renewable methanol is one of the most promising alternative fuels for internal combustion engines. However, its much higher latent heat of vaporization compared to traditional fossil-based hydrocarbon fuels poses new challenges. On both spark-ignition (SI) engines and dual-fuel (DF) engines, methanol can be introduced through injectors installed in the intake path, with its evaporation then causin
The urgent need for improving the energy density of aqueous lithium ion batteries (ALIBs) can be addressed by the implementation of advanced electrode materials and electrolytes. The utilization of layered oxide cathodes, particularly Li[NixCoyMnz]O2 (NCM) materials, is an effective strategy, as they can offer high specific capacities in an appropriate voltage range. However, due to the strong eff
The second Weiglhofer Symposium on Electromagnetic Theory concluded with a round table discussion on “Future Developments.” The panel featured Ibrahim Abdulhalim from the ECE School at Ben Gurion University, Gérard Gouesbet from the Institut National des Sciences Appliquées de Rouen, Gerhard Kristensson from Lund University, Guy Vandenbosch from Katholieke Universiteit Leuven, and Theo Rasing from

Lignocellulose from terrestrial plant biomass is abundant and contains polymeric carbohydrates and lignin; both recognized as attractive renewable feedstocks for energy, chemicals and materials as alternatives to fossils to meet the targets for future sustainable development. Liquid biofuels are particularly important renewable commodities because of the vast infrastructure already in place to use
As a classical polymer acceptor material, N2200 has received extensive attention and research in the field of polymer solar cells (PSCs). However, the intrinsic properties of ground- and excited-states in N2200, which are critical for the application of N2200 in PSCs, remain poorly understood. In this work, the ground- and excited-state properties of N2200 solution and film were studied by steady-
The energy system is undergoing significant changes and is expected to continue to evolve. Energy demand is anticipated to increase, as is renewable energy capacity, and technical solutions are advancing. For electrical power, traditionally centralized production is increasingly complemented by distributed production, transforming fundamental system functionality. These developing factors will aff
Moraxella catarrhalis ubiquitous surface proteins A1 and A2 (UspA1/A2) interfere with the classical pathway of the complement system by binding C4b-binding protein. In this study we demonstrate that M. catarrhalis UspA1 and A2 noncovalently and in a dose-dependent manner bind both the third component of complement (C3) from EDTA-treated serum and methylamine-treated C3. In contrast, related Moraxe
In this paper the heat losses from a novel type of district heating culvert, termed Elgotherm, is investigated and compared to conventional culvert. The insulation material is made of expanded polystyrene and the culvert consists Of four cross-linked polyethylene pipes. The heat losses are calculated using both a time dependent and a stationary finite element model. Measured data from an existing
BACKGROUND: Systemic sclerosis (SSc) has been suggested to cause exocrine pancreatic dysfunction. However, a case-control-based autopsy study failed to associate systemic sclerosis with any pancreatic histopathology. The primary objective of this study was to examine the exocrine pancreatic function in consecutive SSc patients in relation to an age- and sex-matched control group. A secondary objec
Bananas are widely consumed fruits with over 140 metric tons produced annually. As much as 336 metric tons of banana pseudo-stems, sheaths, piths, peels and leaves are produced annually. These wastes are usually discarded via composting, aerobic decomposition, incinerated or simply allowed to rot in the fields. However, these treatments may cause serious environmental and ecological problems.
This article reports model experiments where vocal tract profiles of high and mid unrounded front and high rounded back vowels were systematically modified to simulate small constriction shifts along the hard or soft palate, in order to test A. M. Bell's century-old proposal that small shifts of tongue arch fronting or retraction would yield audible shifts of vowel timbre. Such differences were cl
Surfactants are ubiquitous in formulated products and technologies. As one of the most important commodity chemicals, their remarkable consumption leads to the necessity of finding sustainable alternatives. Although the use of renewable sources limits the available chemical space for a “Green” production, the great variety of naturally occurring precursors, i.e., fatty acids and sugars, opens a my
The reduction of greenhouse gas emission and the effort of carbon neutrality require the improvement of spark-ignition (SI) engines in terms of efficiency and capability to operate on renewable fuels. The electrode wear of spark plugs, used for ignition of novel fuels and lean mixtures, emerges as a significant challenge in this transition. Understanding the physical mechanism and influence from s
Detailed longitudinal dynamics simulations may be used to predict the energy performance of road vehicles. However, including uncertainty in the operating conditions often implies high computational costs. Model-based formulations, in conjunction with statistical methods, may obviate this limitation by directly accounting for stochasticity, thus eliminating the need for simulating large population
