Proton exchange membranes (PEMs) are critical to the performance of vanadium redox flow batteries (VRFBs). Still, conventional perfluorosulfonic acid membranes such as Nafion® suffer from poor ion selectivity and limited long-term stability. In this study, we introduce PEMs prepared from four types of poly(arylene perfluorobenzenesulfonic acid)s, synthesized via polyhydroxyalkylations of biphenyl

A diagonalisation procedure of the Foldy-Wouthuysen type is considered for the single-electron Dirac Hamiltonian as a basis for many-body applications. A modified procedure is suggested. In the diagonalisation procedure the Dirac equation is completely decoupled into two equations of the Pauli type. The expressions for positive- and negative-energy projection operators in the transformed basis are

Efforts to reduce greenhouse gas emissions, globalized markets with intense competition, and generally rising transportation costs emphasize the importance of achieving economically and environmentally sustainable distribution systems. Many international organizations predict that if no new measures are implemented, global carbon dioxide emissions from freight transport will increase to even highe

BACKGROUND: Patients benefit from antiplatelet therapy after coronary-artery bypass grafting (CABG) for an acute coronary syndrome. Whether the addition of ticagrelor to aspirin, as compared with aspirin alone, further reduces the risk of adverse cardiovascular outcomes is unclear.METHODS: In this open-label, registry-based, clinical trial conducted at 22 Nordic cardiothoracic surgery centers, we

In recent years, WUI fire evacuation models have started to be developed. Several now exist, although they are primarily research tools unable to be applied in practice. For this step – moving from research to practice – such models need to build their credibility through testing and application. The WUI-NITY tool has been developed over several previously NIST-funded projects. Once this model is

Implant-associated infections (IAIs) are one of the leading concerns in orthopedics and dentistry as they commonly lead to implant failure. The presence of biofilms and, increasingly frequently, drug-resistant bacteria further impairs the efficacy of conventional antibiotics. Immobilization of antimicrobial peptides (AMPs) on implant surfaces is a promising alternative to antibiotics for preventio

Large skeletal muscle injuries, such as a volumetric muscle loss (VML), often result in an incomplete regeneration due to the formation of a non-contractile fibrotic scar tissue. This is, in part, due to the outbreak of an inflammatory response, which is not resolved over time, meaning that type-1 macrophages (M1, pro-inflammatory) involved in the initial stages of the process are not replaced by

Ti-6Al-4V alloy obtained by powder metallurgy (PM) is a good candidate biomaterial in the manufacture of dental implants but its inherent porosity makes it have worse corrosion behavior than conventionally obtained alloys. In order to improve the corrosion and biological properties, surface modification technologies could be used. The plasma electrolytic oxidation (PEO) process is a novelty proces

A dislocation-based flow stress model is proposed to describe the behavior of Alloy 718 fabricated using laser-based and electron-beam powder bed fusion methods. This physics-based model is adaptive to microstructural variations including the size and volume fraction of γ″ precipitates, crystallographic texture, grain size and the density of immobile dislocations. Coupled with data from thermodyna

This invention is directed to a method for efficiently separating and purifying 13-dehydroxybaccatin III and 10-deacetylpaclitaxel with a high purity of 90% or higher purity, preferably 99.5% or higher purity, from taxane-containing materials such as Taxus species, and the thusly obtained highly pure 13-dehydroxybaccatin III and 10-deacetylpaclitaxel can be used as semi-synthetic precursors of pac

Electric scooters (e-scooters) have emerged as a fundamental component of urban micro-mobility, particularly in European cities during the Covid-19 pandemic. This study employs the Full Consistency Method (FUCOM) and Kendall rank correlation method to assess the preferences and priorities of university students in Catania, Italy, regarding e-scooter adoption. By analyzing influencing factors, this

Teams are dynamic systems that develop, adapt, and change as members interact and respond to their environments. Theory in organizational research emphasizes that team phenomena are multilevel, temporal, and often nonlinear. Yet, the statistical methods commonly used to study teams have lagged behind these theoretical advances, limiting empirical progress. This dissertation addresses this methodol

Despite several randomized controlled trials demonstrating the benefits of combination therapies for metastatic hormone-sensitive prostate cancer (mHSPC), a significant treatment gap persists. This initiative by the Prostate Cancer Foundation (PCF) convened stakeholders from academia, community practices, industry, and patient advocacy groups to address critical challenges in mHSPC care. Expert di

Information- and data literacy, the ability to critically examine and evaluate information and arguments in relation to empirical evidence, is increasingly crucial in a world overflowing with data and information from a multitude of sources. Information- and data literacy in younger students being understudied, we investigate these skills in Swedish 6th graders to learn more about the educational

Timber’s sustainability benefits make it an attractive construction material, but public concerns about fire safety remain a challenge. Many associate timber buildings with higher fire risks, particularly in taller structures, despite trusting regulations and professionals to ensure safety. This highlights a gap between public perception and technical knowledge. Designers have a professional respo
