Unlocking migration politics: researching beyond biases and gaps in migration studies and comparative politics

open access: yes, 2019
International audienceThe focus of research in contemporary international migration and integration politics has long been immigration to Western democracies and their related migration corridors, often defined by colonial history. Just like in any field

Identification and evaluation of shale oil micro-migration and its petroleum geological significance

open access: yesPetroleum Exploration and Development
Taking the Lower Permian Fengcheng Formation shale in Mahu Sag of Junggar Basin, NW China, as an example, core observation, test analysis, geological analysis and numerical simulation were applied to identify the shale oil micro-migration phenomenon. The

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Mechanism of “high-speed braking” effect on heavy oil formation during hydrocarbon migration: a case study of the eastern part of southern slope of Dongying Sag, Bohai Bay Basin

open access: yesShiyou shiyan dizhi, 2020
The phenomenon of "high-speed braking" occurs due to the accumulation of oil and gas during hydrocarbon migration. Then the macromolecular substances are blocked and cannot pass through, while the small molecules can continue to migrate.
