A Comparative Study of Dietary Intake, Nutritional Status, and Frailty in Outpatients and Inpatients with Liver Cirrhosis.

Liver cirrhosis is associated with significant nutritional challenges, including malnutrition, sarcopenia, and frailty, which impact clinical outcomes. The severity of these issues may vary between inpatient and outpatient settings, but there is a limited understanding of how these conditions manifest in these populations. This study aims to compare the nutritional status, dietary intake, and frailty in outpatients and inpatients with liver cirrhosis and to explore potential sex-specific differences.

Simple and sustainable synthesis of perovskite-based optoelectronic material: CsPbBr nanocrystals laser ablation in alcohol.

All-inorganic lead halide perovskite nanocrystals (NCs) have shown great potential as emerging semiconducting materials due to their excellent optoelectronic properties. However, syntheses in solution commonly use high temperatures and toxic solvents, which are obstacles for safety and sustainability of the process. In this work, laser ablation in alcohol is proposed as a simple and sustainable, ligand-free, top-down approach to synthesize CsPbBr nanocrystals in ambient conditions.

Scaled Deposition of TiC MXene on Complex Surfaces: Application Assessment as Rear Electrodes for Silicon Heterojunction Solar Cells.

Two-dimensional transition metal carbides (MXenes) are of great interest as electrode materials for a variety of applications, including solar cells, due to their tunable optoelectronic properties, high metallic conductivity, and attractive solution processability. However, thus far, MXene electrodes have only been exploited for lab-scale device applications. Here, to demonstrate the potential of MXene electrodes at an industry-relevant level, we implemented a scalable spray coating technique to deposit highly conductive (.

Aragonite crystals grown on bones by reaction of CO2 with nanostructured Ca(OH)2 in the presence of collagen. Implications in archaeology and paleontology.

The loss of mechanical properties affecting archeological or paleontological bones is often caused by demineralization processes that are similar to those driving the mechanisms leading to osteoporosis. One simple way to harden and to strengthen demineralized bone remains could be the in situ growth of CaCO3 crystals in the aragonite polymorph - metastable at atmospheric pressure -which is known to have very strong mechanical strength in comparison with the stable calcite. In the present study the controlled growth of aragonite crystals was achieved by reaction between atmospheric CO2 and calcium hydroxide nanoparticles in the presence of collagen within the deteriorated bones.
