Hydrophobic MFI‐Type Zeolites via Alkali‐Cation‐Induced Defect Healing: Implications for Adsorbent and Catalyst Design

Advanced Materials, EarlyView.
Sub‐stoichiometric amounts of Na+ or K+ enhance defect healing during Silicalite‐1 (MFI) and TS‐1 calcination by promoting Si–O–Si annealing and healing framework vacancies. The resulting defect‐free zeolites are more hydrophobic and show improved butanol/water separation and improved activity and selectivity in the epoxidation of 1‐hexene, offering a ...

Frequent flyers: recurrent large vessel occlusion requiring thrombectomy

Stroke and Vascular Neurology
Background Repeat thrombectomy for recurrent large vessel occlusion (LVO) is uncommon but clinically consequential. Although previous studies have described general causes of recurrent LVO, the association between recurrence timing and underlying ...

Acute ischaemic stroke interventions: large vessel occlusion and beyond

Stroke and Vascular Neurology, 2020
Care for acute ischaemic stroke is one of the most rapidly evolving fields due to the robust outcomes achieved by mechanical thrombectomy. Large vessel occlusion (LVO) accounts for up to 38% of acute ischaemic stroke and comes with devastating outcomes ...

Platelet-rich emboli in cerebral large vessel occlusion are associated with a large artery atherosclerosis source

, 2021
Background and Purpose— Nearly 30% of large vessel occlusion acute ischemic stroke clots are from an unknown source. We assessed histological clot composition in a series of patients with large vessel occlusion and investigated correlations between clot ...

Asymmetrical Bioimpedance in the Anterior Circulation for Urgent Stratification of suspected Stroke (ABACUS Stroke): study protocol for a diagnostic accuracy study

Diagnostic and Prognostic Research, 2020
Background Early identification and treatment of stroke improve outcome. Ischaemic stroke due to large vessel occlusion (LVO) benefits from time-critical thrombectomy but this is only available in highly specialised healthcare services.
