Thin yet robust solid-state electrolytes (SSEs) with efficient Li transport are highly desirable for realizing high-energy-density all-solid-state lithium-metal batteries (ASSLMBs). Herein, an ultrathin (10 μm) SSE with ordered ion pathways is reported for scalable ASSLMBs production. The SSE is supported by the poly (ether sulfone) scaffold, which not only improves mechanical strength and safety capability but also enables low-tortuous Li transport along the inner walls of its vertically aligned microchannels. The fast and direct Li conduction facilitates uniform Li deposition and the scaffold-reinforced structure provides superior dendrite suppression capability, together enhancing interfacial stability with the Li metal anode. As a result, the composite electrolyte exhibits room temperature ionic conductivity up to 0.10 mS cm and Li transference number up to 0.51. Moreover, the LiFePO/Li ASSLMBs achieve capacity retention of 81 % after 300 cycles at 1 C/60 °C and 84 % after 100 cycles at 0.1 C/room temperature. Notably, the cell is able to operate safely and exhibit excellent electrochemical performance under high temperature of 100 °C. The versatility of the strategy is illustrated by a demonstration of the LiNiCoMnO system.

Barium fluoride borosilicate glass samples reinforced with varying amounts of GdO (BSBLG0-BSBLG4) have been manufactured using the conventional melt quenching procedure in order to provide additional research on the type of borosilicate glass. Structural, physical, and linear optical characteristics as well as γ-ray attenuation capacity of barium fluoride borosilicate doped with GdO was investigated. X-ray diffraction pattern proving the amorphous nature of the glass samples due to the absence of a distinctive crystalline characteristic peak.

The rapid development in agriculture and industrial sectors has raised some serious global issues like heavy metals pollution of water resources. Cadmium (Cd) is amongst the major water pollutants worldwide. In this study, two novel sorbents were prepared by using post-consumer textile waste (PCTW).

Both experimental and theoretical studies have shown that magnetic fields may affect, among others, the macroscopic spin-orbital ordering, charge transport, bubble release, and electron transfer kinetics. This paper highlights Electrochemical Impedance Spectroscopy (EIS) as a tool to analyze and separate the effects of magnetic field on both the oxygen reduction and evolution reactions at cobalt iron oxide electrodes.

Background: Carbon-ion radiotherapy provides steep dose gradients that allow the simultaneous application of high tumor doses as well as the sparing of healthy tissue and radio-sensitive organs. However, even small anatomical changes may have a severe impact on the dose distribution because of the finite range of ion beams.
Purpose: An in-vivo monitoring method based on secondary-ion emission could potentially provide feedback about the patient anatomy and thus the treatment quality.

Background: This study evaluates the fracture resistance of apical plugs created from Biodentine and mineral trioxide aggregate (MTA) in thicknesses of 3 and 5 mm within simulated open apex tooth models.
Methods: Fifty human maxillary central incisors were obtained from a pool of freshly extracted teeth. In order to replicate open apices without cavity preparation, ten teeth in the control group received apical-to-coronal preparation with Peeso reamers.
