The current guidelines for diagnosis, prognosis, and treatment of endometrial cancer (EC), based on clinicopathological factors, are insufficient for numerous reasons; therefore, we investigated the relevance of miRNA expression profiles for the discrimination of different EC subtypes. Among the miRNAs previously predicted to allow distinguishing o...

Hydrophilic matrix systems can be found in a wide range of extended release pharmaceutical formulations. The main principle of these systems is that upon contact with water, the hydrophilic component swells to form a hydrated gel layer which controls drug release. The following work demonstrates an explorative study into the use of dissolution imag...

Rechargeable Li-ion technology is considered as the battery of choice for electric vehicles and large-scale smart grids thanks to its unrivaled electrochemical properties (1). However, important amelioration in battery performance are still required, particularly in terms of energy density, power delivery capabilities and cycle life. The search for...

To meet the increasing energy demand for electric vehicles, renewable and grid storage systems, the design and the manufactory of new electrode materials is crucial. Recently, huge efforts have been oriented to the development of high capacity anode material as one of the important components for next-generation lithium-ion batteries. Compared to g...

Abstract Polydopamine (PDA) is a bioderived organic electrode material which exhibits a low capacity of ∼100 mAh.g−1 due to the large PDA aggregates formed at the electrode during self-polymerization of DA. In this work, it found that a simple grafting of sulfonate groups via Michael addition can endow sulfonated PDA with superior electrochemical p...

As the demand for batteries increases with the development of electric vehicles, the energy density of lithium-ion batteries (LIBs) should be continuously enhanced. Due to the excellent theoretical specific capacity, silicon (Si) is the most promising anode material for LIBs. Nevertheless, the application of Si-based anodes is constrained by critic...

Alloy systems like Si/FeSi2 nano composites have great potential as stable anode materials in Li-ion batteries, but their characterization at different scales and throughout their ageing remains challenging. Here the authors use scattering and 2D/3D imaging techniques combined with modeling to elucidate morphology changes upon cycling of the anode....

AbstractSilicon-based electrodes are attractive candidates as anodes for Li-ion batteries due to their high theoretical specific capacity. However, repeated lithiation/delithiation causes significant morphological changes in the silicon particles, which results in formation of highly porous silicon structures and severe side reactions at the silico...

In this work, the properties of silver-modified LiMn 2 O 4 cathode materials are revisited. We study the influence of calcination atmosphere on the properties of the Ag-coated LiMn 2 O 4 (Ag/LMO) and highlight the silver oxidation. The effect of the heat treatment in vacuum is compared with that in air by the characterization of the structure, spec...
