Sustainable Germanium Recovery From Germanium Dioxide via Halogen‐Free Chemical Vapor Transport

open access: yesChemistry – A European Journal, EarlyView.
Recovery of the critical element Ge from GeO2 and SiO2/GeO2 mixtures was investigated based on an endothermic chemical vapor transport via GeO, formed with natural gas or a hydrogen(10%)‑argon(90%) mixture and water vapor. (This picture was partly created with AI, engine: Adobe Firefly).

Mechanistic Insights Into Sustainable Catalytic Pyrolysis of Biomass‐Derived Ferulic Acid: The Role of Alumina Regeneration

open access: yesChemistry – A European Journal, EarlyView.
Surface‐bound ferulate phenolate complexes undergo styrene‐like polymerization on alumina, yielding a polymeric carbonaceous layer that progressively transforms into polyaromatic carbon domains with concomitant release of aromatic products, while parallel surface‐assisted decarboxylation produces 4‐vinylguaiacol. ABSTRACT A fundamental understanding of

Sweetspot Mapping in Deep Brain Stimulation: Strengths and Limitations of Current Approaches

open access: yesNeuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives Open questions remain regarding the optimal target, or sweetspot, for deep brain stimulation (DBS) in, for example, Parkinson's disease. Previous studies introduced different methods of mapping DBS effects to determine sweetspots. While having a direct impact on surgical targeting and postoperative programming in DBS, these methods ...

Three‐dimensional observation of the muscle–tendon integration process in mouse embryos

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Muscle–tendon integration is a crucial step in the morphogenesis of the vertebrate locomotion system. As the limb muscle and tendon progenitor cells derive from distinct embryonic origin, their integration requires precise mutual positioning.

Deep Brain Stimulation Reduces Conflict‐Related Theta and Error‐Related Negativity in Patients With Obsessive–Compulsive Disorder

open access: yesNeuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives Obsessive–compulsive disorder (OCD) is a psychiatric disorder with alterations of cortico‐striato‐thalamo‐cortical loops and impaired performance monitoring. Electrophysiological markers such as conflict‐related medial frontal theta (MFT) and error‐related negativity (ERN) may be altered by clinically effective deep brain ...

Exercise limitations in amyloid cardiomyopathy assessed by cardiopulmonary exercise testing—A multicentre study

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1326-1335, April 2025.
Abstract Aims Amyloid cardiomyopathy is caused by the deposition of light chain (AL) or transthyretin amyloid (ATTR) fibrils, that leads to a restrictive cardiomyopathy, often resulting in heart failure (HF) with preserved or reduced ejection fraction.

Inter‐Reader Agreement for CT and MRI LI‐RADS Version 2018: An Individual Participant Data Meta‐Analysis

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The Liver Imaging Reporting and Data System (LI‐RADS) is a classification system to diagnose hepatocellular carcinoma (HCC) noninvasively. The reported LI‐RADS inter‐reader variability in single‐center studies highlights the need to better understand the variability on a broader scale.
