Raman microscopy of the Cu/LiAlGe(PO) solid electrolyte interphase.

LiAlGe(PO) (LAGP) is a promising solid-state electrolyte (SSE) for solid-state batteries but suffers from side reactions with Li metal resulting in cracking and interfacial resistance rise which hinders its practical application. Herein, in operando Raman spectroscopy was performed to gain insights into local chemical and structural transformations of the Cu/LAGP interface during cathodic polarization.

Detection of an internal density change in an anthropomorphic head phantom via tracking of charged nuclear fragments in carbon-ion radiotherapy.

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.

CFTR represses a PDX1 axis to govern pancreatic ductal cell fate.

Inflammation, acinar atrophy, and ductal hyperplasia drive pancreatic remodeling in newborn cystic fibrosis (CF) ferrets lacking a functional cystic fibrosis conductance regulator (CFTR) channel. These changes are associated with a transient phase of glucose intolerance that involves islet destruction and subsequent regeneration near hyperplastic ducts. The phenotypic changes in CF ductal epithelium and their impact on islet function are unknown.

Evaluation of Alternative Lithium Salts for High-Voltage Lithium Ion Batteries: Higher Relevance of Plated Li Morphology Than the Amount of Electrode Crosstalk.

Increasing the upper cut-off voltage (UCV) enhances the specific energy of Li-ion batteries (LIBs), but is accompanied by higher capacity fade as a result of electrode cross-talk, i.e., transition metals (TM) dissolution from cathode and deposition on anode, finally triggering high surface area lithium (HSAL) formation due to locally enhanced resistance.

Vaginal metastasis in gestational trophoblastic neoplasia: Experience from Sheffield trophoblastic disease Centre and recommendations for management.

Introduction: Gestational trophoblastic neoplasia (GTN) is rare in the UK, with an estimated incidence of one in 50,000 live births. Cases of vaginal metastasis are even rarer, with only eight case series reporting 187 cases over the past 40 years. Management recommendations in the literature are scarce despite the potential risk of massive, potentially life-threatening vaginal haemorrhage.
