AI Article Synopsis
- The study explores the promising potential of a two-dimensional monolayer semiconductor material, highlighting its thin profile and excellent optoelectronic properties.
- Researchers used first-principles density functional theory to analyze a van der Waals heterostructure made from two-dimensional monolayers, noting its ability to form a low-resistance contact.
- By applying an electric field and vertical stress, the team found a way to modify the contact type from ohmic to p-type Schottky, suggesting opportunities for developing advanced, reconfigurable nano-devices.
Article Abstract
The two-dimensional monolayer is an emerging semiconductor material that offers considerable promise due to its ultra-thin profile, tuneable mechanical properties, excellent optoelectronic properties and exceptional environmental stability. The van der Waals (vdW) heterostructure formed by stacking such two-dimensional monolayers has demonstrated superior performance across various domains. In this study, a vdW heterostructure combining the two-dimensional and monolayers is examined using first-principles density functional theory. In its ground state, this van der Waals heterostructure establishes an ohmic contact with an exceptionally low potential barrier height. By modulating the vdW heterostructure with an applied electric field of -0.1 V/Å and under vertical stress, we discovered that and can transition from an ohmic contact to a p-type Schottky with an ultra-low Schottky barrier height (SBH). Our observations may give valuable insights for designing reconfigurable, tuneable Schottky nano-devices with enhanced electronic and optical properties based on .

Intravascular lithotripsy in heavily calcified chronic total occlusion: procedural and one-year clinical outcomes.
Catheter Cardiovasc Interv
October 2024
Department of Cardiology, Leiden University Medical Center, Leiden, The Netherlands.
Article Synopsis
- The study investigates the use of intravascular lithotripsy (IVL) in treating heavily calcified chronic total occlusions (CTOs), noting that calcification leads to worse patient outcomes.
- It analyzes data from 404 patients, finding that procedural success rates and safety outcomes were similar for both CTO and non-CTO patients.
- The conclusion emphasizes that IVL is effective and safe for managing heavily calcified lesions, supporting its use in clinical practice.
An optimized b-value sampling for the quantification of interstitial fluid using diffusion-weighted MRI, a genetic algorithm approach.

Department of Radiology and Nuclear Medicine, Maastricht University Medical Center, Maastricht, The Netherlands.
Article Synopsis
- Multi-b-value diffusion-weighted MRI techniques can measure brain tissue properties but face challenges due to SNR and the selection of b-values for accurate data gathering.
- This study uses a genetic algorithm to determine the most effective b-values for estimating interstitial fluid in the brain, comparing its performance to other sampling methods.
- Results showed that the optimized b-value scheme significantly reduced the root mean square error (RMSE), improving the accuracy of the diffusion component estimation related to interstitial fluid.
Minimally invasive lobectomy versus stereotactic ablative radiotherapy for stage I non-small cell lung cancer.
Eur J Cardiothorac Surg

Department of Surgery, Netherlands Cancer Institute-Antoni van Leeuwenhoek Hospital, Amsterdam, Netherlands.
Objectives: A minimally invasive lobectomy (MIL) is the standard treatment for stage I non-small cell lung cancer (NSCLC) in medically operable patients. Stereotactic ablative radiotherapy (SABR) is recommended for inoperable patients and has been proposed as a potential alternative for operable patients as well. Here, we present the results of a feasibility study in preparation for a nationwide retrospective cohort study, comparing outcomes between both treatment modalities.

August 2021
Department of Dermatology/Allergology, University Medical Center Utrecht, University of Utrecht, Utrecht, The Netherlands.
Article Synopsis
- The study evaluated the effectiveness of a specific IgE test for diagnosing peanut allergies in children, aiming to reduce reliance on more invasive food challenge tests.
- It involved 150 children aged 3.5 to 18 in the Netherlands, comparing results from the IgE test with actual peanut ingestion to determine allergy status.
- The findings showed high diagnostic accuracy for the IgE test, identifying patients as peanut-tolerant or allergic, and potentially saving healthcare costs by using this method instead of national guidelines.
Morbidity and mortality after anaesthesia in early life: results of the European prospective multicentre observational study, neonate and children audit of anaesthesia practice in Europe (NECTARINE).

Background: Neonates and infants requiring anaesthesia are at risk of physiological instability and complications, but triggers for peri-anaesthetic interventions and associations with subsequent outcome are unknown.
Methods: This prospective, observational study recruited patients up to 60 weeks' postmenstrual age undergoing anaesthesia for surgical or diagnostic procedures from 165 centres in 31 European countries between March 2016 and January 2017. The primary aim was to identify thresholds of pre-determined physiological variables that triggered a medical intervention.
