Strong Enhancement of Light Emission in Core-Shell InGaN/GaN Multi-Quantum-Well Nanowire Light-Emitting Diodes by Incorporating Graphene Quantum Dots.

One-dimensional (1D) vertical nitrides are highly attractive for light-emitting diode (LED) applications because they are useful for overcoming the drawbacks of conventional GaN planar structures. However, the internal quantum efficiency (IQE) of GaN multi-quantum-well (MQW) nanowire (NW) LEDs, typical 1D GaN structures, is still too low to replace standard planar LEDs. Here, we report a phenomenon of light amplification from core-shell InGaN/GaN NW LEDs by incorporating graphene quantum dots (GQDs).

Atomic-Level Stoichiometry Control of Ferroelectric HfZrO Thin Films by Understanding Molecular-Level Chemical Physical Reactions.

HfO-based thin films have garnered significant interest for integrating robust ferroelectricity into next-generation memory and logic chips, owing to their applicability with modern Si device technology. While numerous studies have focused on enhancing ferroelectric properties and understanding their fundamentals, the fabrication of ultrathin HfO-based ferroelectric films has seldom been reported. This study presents the concept of atomic-level stoichiometry control of ferroelectric HfZrO films by examining the molecular-level interactions of precursor molecules in the atomic layer deposition (ALD) process through theoretical calculations.

Post-transplant cyclophosphamide plus anti-thymocyte globulin decreased serum IL-6 levels when compared with post-transplant cyclophosphamide alone after haploidentical hematopoietic stem cell transplantation.

Background: Post-transplantation cyclophosphamide (PTCy) and anti-thymocyte globulin (ATG) are common prophylactic strategies for graft-versus-host disease (GVHD) after haploidentical hematopoietic stem cell transplantation (haplo-HSCT). Interleukin (IL)-6 is a surrogate marker for cytokine release syndrome (CRS) and acute GVHD.

Method: The clinical outcomes and complications of haplo-HSCT with PTCy plus ATG versus PTCy monotherapy were compared according to serum IL-6 levels at Chungnam National University Hospital (Daejeon, South Korea) from January 2019 to February 2023.

The role of mTOR activation in steroid-resistant asthma: insights from particulate matter-induced mouse model and patient studies.

Particulate matter (PM) exposure has been proposed as one of the causes of steroid resistance. However, studies investigating this using patient samples or animals are still lacking. Therefore, in this study, we aimed to investigate the changes in cytokines and mTOR (mammalian target of rapamycin) activation in patients with steroid resistant asthma and the role of mTOR in a mouse model of steroid resistant asthma induced by PM.
