KI im Unternehmen einführen
Künstliche Intelligenz ist längst mehr als ein Zukunftsthema. Sie verändert bereits heute den Arbeitsalltag vieler Unternehmen. Sie kann Prozesse vereinfachen, Routineaufgaben beschleunigen und neue Möglichkeiten für Analyse, Kommunikation, Organisation, Grafik und Kundenservice eröffnen. Doch bevor KI sinnvoll eingesetzt werden kann, braucht es vor allem eines: Wissen. Der erste Schritt sollte daher nicht der Kauf eines Tools sein, sondern der gezielte Aufbau von KI-Kompetenz.
Recent Advancements in Bulk Processing of Rare‐Earth‐Free Hard Magnetic Materials and Related Multiscale Simulations
1 Introduction Permanent magnets have a wide range of applications in our everyday lives. The market is currently dominated by rare-earth element (REE)-based permanent magnets with excellent hard magnetic properties. They are based on certain REE, especially Sm or Nd (both light REEs) and Dy or Tb (both heavy REEs).
Influence of Competitive C-P Segregation on Austenite Grain Growth in Iron Alloys
1 Introduction In steelmaking down-stream processes controlling the high-temperature austenitic microstructure is essential for high-quality standards in steel production. In general, it is advisable to maintain a refined and homogeneous microstructure throughout all stages of steel processing, as large grains or wide and bimodal grain size distributions can lead to material failures or introduce defects that may persist or re-emerge during later processing steps.
METAB‐HTX: prospective, longitudinal cohort study evaluating cardiac and systemic metabolism after heart transplantation
Introduction Advanced heart failure occurs in up to 10% of heart failure patients with increasing prevalence.1 In these patients, heart transplantation (HTX) improves life expectancy from a median of 12.2 months to 12.2 years.2, 3 However, there is still a substantial need to improve long-term survival post-HTX. To address this need, an in-depth understanding of factors that lead to worsening of cardiac function and mortality is needed.
Impaired mitochondrial ketone body oxidation in insulin resistant states
Abstract Background and aims: Reduced mitochondrial function has been implicated in metabolic disorders like type 2 diabetes (T2D), obesity, and metabolic dysfunction-associated steatotic liver disease (MASLD), which are tightly linked to insulin resistance and impaired metabolic flexibility.
Amorphous shear band formation in crystalline Si-anodes governs lithiation and capacity fading in Li-ion batteries - Communications Materials
Abstract The cycling stability of Li-ion batteries is commonly attributed to the formation of the solid electrolyte interphase (SEI) layer, which is generated on the active material surface during electrochemical reactions in battery operation. Silicon experiences large volume changes upon the Li-insertion and extraction, leading to the amorphization of the silicon-interface due to the permeation of the Li-ions into the silicon.
Unveiling the mechanism of deformation-induced supersaturation - Scientific Reports
Abstract A Cu-6at%Ag cast alloy was deformed by means of high-pressure torsion to different applied strain levels until a steady-state regime is reached. The continuous structural refinement is attended by the successive dissolution of the Ag precipitates in the Cu matrix. The results show that the Ag regions need to fall below a phase size of ~ 5 nm to fully dissolve.
High-resolution respirometry reveals altered mammalian tissue ketone body oxidation in different cardiometabolic diseases
Abstract Abnormal mitochondrial oxidative phosphorylation (OXPHOS) is key to the pathogenesis of several cardiometabolic diseases. The ketone bodies (KBs), beta-hydroxybutyrate (HBA) and acetoacetate (ACA), are critical for tissue-specific energy metabolism under various pathophysiological conditions. However, robust methods quantifying their contribution as substrates for OXPHOS are lacking.
High‐throughput first‐principles calculations and machine learning of grain boundary segregation in metals
The segregation of solute elements to defects in metals plays a fundamental role for microstructure evolution and the materials performance. However, the available computational data is scattered and inconsistent due to the use of different simulation parameters and methods. We present a high throughput study on grain boundary and surface segregation together with their effect on grain boundary embrittlement using a consistent first-principles methodology.

Probing the composition dependence of residual stress distribution in tungsten-titanium nanocrystalline thin films - Communications Materials
Abstract Nanocrystalline alloy thin films offer a variety of attractive properties, such as high hardness, strength and wear resistance. A disadvantage is the large residual stresses that result from their fabrication by deposition, and subsequent susceptibility to defects. Here, we use experimental and modelling methods to understand the impact of minority element concentration on residual stresses that emerge after deposition in a tungsten-titanium film with different titanium concentrations.
