This study succeeded to prepare three pure phases of Mn2O3, Mn3O4 beside one of the best cathode materials, spinel LiMn2O4. LiMn2O4 with high phase purity and crystallinity was synthesized by a facile, cost effective and one step synthesis method. The structure and morphology of the powders were studied in detail by means of X-ray diffraction (XRD), thermogravimetric analysis (TGA), field emission
(Graph Presented) In the search for new cathode materials for rechargeable lithium batteries, conversion-type materials have great potential because of their ability to achieve high specific capacities via the full utilization of transition metal oxidation states. Here, we report for the first time that copper phosphate can be used as a novel high-capacity cathode for rechargeable Li batteries, ca
A Na2MnPO4F/C nanocomposite material is successfully synthesized via spray drying, followed by a high-temperature sintering method. It is shown that the highly phase-pure Na2MnPO4F with symmetry of the P21/n space group is uniformly embedded in the carbon networks, which play a key role in building up a highly efficient, electron-flow channel and elevating the electronic conductivity of the nanoco
Facilitated CO stripping: Partial metallization of TiO2 nanoparticles (NPs) by electroreduction in the molten, eutectic mixture of CaCl2 and NaCl at 600 °C produces nano- and submicro-sized Ti2O and CaδTiOx (perovskites, x/× δ 2) that can significantly promote the catalytic activity of Pt NPs towards the oxidation of CO and CH3OH in acidic solutions
Na2FePO4F is a promising cathode material for Na-ion batteries owing to its relatively high discharge voltage and excellent cycling performance. Now, the long- and short-range structural evolution of Na2FePO4F during cycling is studied by in situ high-energy X-ray diffraction (XRD), ex situ solid-state nuclear magnetic resonance (NMR), and first-principles DFT calculations. DFT calculations sugges
Multiple myeloma (MM) is the second most common hematological malignancy, characterized by clonal proliferation of neoplastic plasma cells in the bone marrow, causing hematopoietic suppression and impaired antibody production. Bacterial infections remains a major cause of mortality in MM. As in in most malignancies, myeloma cells modify their microenvironment to promote tumor growth, including sup
En kortlek med 67 situationskort för universell utformning för lärande (UDL) utvecklades vid fyra internationella lärarworkshops för att hjälpa lärare att förstå och förbättra inkluderande undervisning, dvs. att vara proaktiva och förberedda på en mångfald av studenter. De utskrivna korten har hämtats eller beställts av cirka 150 personer. Denna artikel presenterar resultaten av en enkät som skickA deck of 67 context cards for Universal Design for Learning (UDL) was developed at four international teacher workshops, to help teachers understand and improve inclusive teaching, i.e. to be proactive and prepared for student diversity. The printed cards have been picked up or ordered by approximately 150 people. This paper presents the results of a questionnaire sent to 44 people.The results fr
UNLABELLED: The primary objective of this study was to investigate whether ligand-receptor interactions (LRIs) between IGHG and FCGR gene products are associated with progression to type 1 diabetes (T1D). Using two completed clinical trials (DPT-1 and TN07), we applied next-generation targeted sequencing to genotype IGHG and FCGR genes in a cohort of 1,214 individuals and assessed LRI associations
Mystical-type experiences can be induced through techniques like hypnosis and meditation. These experiences are common in near-death experiences (NDEs) and have been linked to paranormal beliefs. This study explored auto-induced cognitive trance (AICT) as a method to induce mystical-type experiences and NDE outside of life threatening situations (NDE-like), as well as examining the influence of fa

Glioblastoma (GBM) is characterized by fast progression, infiltrative growth pattern, and a high relapse rate. A defining feature of GBM is the existence of spatially and functionally distinct cellular niches, where malignant cells engage in paracrine crosstalk with cell types comprising the tumor microenvironment. Here, we identify pericytes as the most active paracrine signaling hub within the t
Among the many approaches to improve the performance of lithium-metal batteries, ternary polyethylene oxide/ionic liquid/lithium salt electrolytes offer several advantages such as low flammability, high conductivity (vs. polyethylene oxide/lithium salt electrolytes) and, to a large extent, limiting the growth of dendrites at moderate currents. However, they suffer from relatively low mechani
Det svenska elsystemet genomgår stora förändringar. Elbehovet väntasöka markant då industrin elektrifieras och transportsektorn blir fossilfrisamtidigt som en allt högre andel av elen kommer från väderberoendekraftslag. Och mitt i denna elektrifierade energiomställning står elnätensom en bortglömd möjliggörare, eller i värsta fall bromskloss. Behovetav reinvesteringar i åldrade nät är stort samtid
The development and application of Electrochemical Quartz Crystal Microbalance (EQCM) sensing to study metal electroplating, especially for energy storage purposes, are reviewed. The roles of EQCM in describing electrode/electrolyte interface dynamics, such as the electric double-layer build-up, ionic/molecular adsorption, metal nucleation, and growth, are addressed. Modeling of the QCM sensor is
This paper provides a comprehensive overview of how emblems wereused on Swedish royal medals and commemorative coins duringthe seventeenth century, a period marked by the rise of the SwedishEmpire. Focusing on numismatic objects that thematize royalsuccession and coronations, it focuses on how emblems were utilizedacross multiple monarchs, touching on the origin of the emblems andhow the use of em
Adolescent girls are particularly susceptible to iron deficiency due to increased iron requirements during the pubertal growth spurt, combined with iron loss following menarche. This study aimed to investigate the prevalence of heavy menstrual bleeding in an adolescent population using the SAMANTA questionnaire and to explore its relationship with dietary habits and iron deficiency. This cross-sec
Characteristic Mode analysis is a widely used technique in antenna design, providing insight into the fundamental electromagnetic behavior of radiating structures. In this paper, we establish fundamental bounds on the slope of characteristic mode eigenvalues and angles, demonstrating that their rate of change is subject to fundamental constraints for all possible realizations within a given design
