Summary: Gestational diabetes mellitus is a common endocrine disease during pregnancy that can lead to adverse pregnancy outcomes. Continuous glucose monitoring (CGM) can effectively monitor blood glucose changes and improve gestational outcomes by reducing fluctuations and serious hypoglycemia or hyperglycemia events. Time in range (TIR) is an important indicator of blood glucose level, and patients with higher TIR during pregnancy have better outcomes.

Summary: The outpatient use of continuous glucose monitoring (CGM) has been supported by consistent data to improve glycemic control and reduce hypoglycemia burden. However, limited data exist regarding its use in the hospital setting, especially in non-intensive care units (non-ICU). This Expert Opinion paper evaluates the state of the art and provides a practical model for implementing CGM in hospitals. The practical approach outlined here can guide hospitals in their diabetes management initiatives using CGM to identify the most suitable patients and maximize clinical benefits.

Summary: The National Institute for Clinical Excellence (NICE) recommends continuous glucose monitoring (CGM) for adults and children with diabetes at risk of hypoglycemia. CGM can detect silent hypoglycemia in neonates, which is associated with poor neurodevelopmental outcome. Despite advancements in technology, adoption in clinical practice is limited due to device limitations for newborns. However, CGM offers the opportunity to improve understanding of hypoglycemia risks and the impact of interventions.

Summary: Randomised controlled trials and other prospective clinical studies have traditionally used HbA1c as a measure of average blood glucose levels, but with the increasing use of continuous glucose monitoring (CGM), CGM-derived metrics are being considered for use in these studies. This consensus statement recommends the use of CGM data in clinical studies to provide additional clinical information beyond HbA1c. Standardizing the collection and reporting of CGM data in clinical trials can enhance the interpretability of the data and inform therapeutic decisions related to hypoglycaemia, postprandial hyperglycaemia, and glucose variability.

Summary: A sensitive and scalable phosphorescent oxygen sensor formulation using ethyl cellulose (EC) and polystyrene (PS) nanoparticles stabilized with various surfactants was evaluated. The EC nanoparticles showed higher sensitivity and narrow size distribution compared to PS nanoparticles. The preferred formulation of EC nanoparticles protected with PF68 exhibited high oxygen sensitivity, wide phosphorescence lifetime response, and low cytotoxicity. These EC-PF68 nanoparticles were then encapsulated in alginate microspheres to create phosphorescent nanoparticles-in-microparticle (NIMs) for glucose and lactate sensing.

Summary: This study optimizes a sol-gel synthesis method for the fabrication of MoS2 films, enabling the deposition of large area MoS2 films on different substrates. The films exhibit desired chemical and physical properties expected for 2D-MoS2 and show uniformity across the entire film area. Photodetector devices made using this fabrication method demonstrate responsivity values of few mA/W in the NUV-VIS-NIR spectrum, expanding the spectral response range of MoS2-based photodetectors previously reported. Despite the influence of residual electronic defects on the device response time and light-to-dark current ratio, this work presents a scalable and versatile process for fabricating 2D-MoS2 and photodetectors based on it.

Summary: Monolayer transition-metal dichalcogenides (TMDCs) combined with organic semiconductors form heterostructures with tunable optoelectronic properties. The efficiency and lifetime of photoinduced charge transfer can be controlled by tuning the energy level offset. Direct electron-hole recombination across the hybrid interface is not the main decay pathway for photogenerated carriers, instead, holes are suggested to transfer back to the TMDC layer. Adding a 1 nm LiF interlayer can slow down interfacial carrier recombination without suppressing free carrier formation.

Summary: Quantum dot (QD) materials are being increasingly used in display applications due to their high color purity and fluorescence quantum yield, resulting in devices with higher brightness and efficiency. In this study, a zinc selenide-based blue QD material was synthesized and air-fabricated into light-emitting diodes (LEDs) and single-carrier devices. The QD-LED devices showed pure deep blue/purple fluorescence emission with a high photoluminescence quantum yield of 78%. By utilizing different electron transport layers, the devices achieved maximum luminance values of 6200 cd m(-2) and 3000 cd m(-2) with turn-on voltages of 3.5 V and 3 V, respectively. This study demonstrates, for the first time, the air-fabrication of ZnSe-based QD-LEDs, opening up possibilities for large-scale display applications and high-performance printed electronics.

Summary: 4D scanning transmission electron microscopy (4D-STEM) is a powerful technique that can characterize electron-transparent samples with high spatial resolution. By rastering an electron beam over a sample area and acquiring transmission diffraction patterns, 4D-STEM can provide detailed information about the atomic structure, crystallinity, orientation, and other properties of the sample. It can be used in scanning electron microscopes (SEMs) to study 2D materials and vdWH, with their inherently thin thickness. A unique 4D-STEM-in-SEM system is applied to reveal the single crystallinity of MoS2 exfoliated with gold-mediation and determine the crystal orientation and coverage of both components in a C60/MoS2 vdWH.

Summary: 2D transition metal dichalcogenides (TMDCs) are semiconductors with potential for optoelectronic applications, and their properties can be altered by chemically engineering the substrate surface. This study demonstrates local doping and adjustment of the electronic and optical properties of TMDCs (WSe2 and MoS2) by decorating the substrate with self-assembled monolayers (SAMs) with different molecular dipoles and dielectric constants. The interaction between SAMs and TMDCs leads to changes in the electronic band gap width, which can be predicted using the Schottky-Mott rule and knowledge of the dielectric screening effects. Understanding these effects allows for accurate prediction of TMDCs behavior for device design.

Summary: Two-dimensional transition metal dichalcogenides (TMDCs) show great potential as semiconductors for optoelectronic applications in the ultraviolet-visible spectral range, but their characteristics under x-rays have not been characterized yet. This paper demonstrates the use of TMDCs as direct x-ray detectors, and improves the x-ray photoresponse by coupling with a polymer film integrated with a scintillator. This may pave the way for the production of ultrathin real-time dosimeters for in vivo applications.

Summary: Graphitic carbon nitrides are promising materials for overcoming the limitations of 0D molecular and 1D polymer semiconductors due to their covalently-bonded, layered, and crystalline structure. This study investigates the structural, vibrational, electronic, and transport properties of poly(triazine-imide) (PTI) derivatives with and without intercalated ions. It is found that PTI nano-crystals exhibit high charge carrier density and THz conductivity, but the electroluminescence from the pi-pi* transition is quenched, limiting their use in electroluminescent devices. Macroscopic charge transport in PTI films is also hindered by disorder at crystal-crystal interfaces.
