Hydrogen Embrittlement in Pipeline Steels and Welds

, 2022
In the energy transition towards a low carbon economy, the EU strives to provide a hydrogen grid of almost 23000 km by 2040. 75% is expected to be obtained by retrofitting existing pipelines for the transport and storage of hydrogen gas. However steels are prone to hydrogen embrittlement, i.e., hydrogen reduces their ductility and fracture toughness ...

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

Molecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.
