Medications for chronic obstructive pulmonary disease: a historical non-interventional cohort study with validation against RCT results

open access: yesHealth Technology Assessment, 2021
Background: Chronic obstructive pulmonary disease treatment is informed by randomised controlled trial results, but it is unclear if these findings apply to people excluded from these trials.

Seasonal influence on TORCH infection and analysis of multi‐positive samples with indirect immunofluorescence assay

open access: yesJournal of clinical laboratory analysis (Print), 2019
TORCH including the pathogens of Toxoplasma gondii (TOX), rubella virus (RV), cytomegalovirus (CMV), and herpes simplex virus (HSV) causes intrauterine infections and poses a worldwide threat to women especially in pregnancy.

A novel cassette method for probe evaluation in the designed biochips [PDF]

open access: yes, 2014
A critical step in biochip design is the selection of probes with identical hybridisation characteristics. In this article we describe a novel method for evaluating DNA hybridisation probes, allowing the fine-tuning of biochips, that uses cassettes with ...

Optical Charge Trap Memory Based on Graphene/ZnO Heterostructures for Long‐Term Retention and Adaptive Learning

open access: yesAdvanced Electronic Materials, EarlyView.
A biocompatible graphene/ZnO optical charge trap memory (CTM) is reported with over 54 h retention, enabled by interfacial photodoping. Using transient absorption spectroscopy and electrical analysis, charge transfer quenching is elucidated and reveal that a large energy barrier at the interface is responsible for long‐term memory retention.

Inhaled corticosteroids versus long-acting beta -agonists for chronic obstructive pulmonary disease (Review). [PDF]

open access: yes, 2011
Long-acting beta(2)-agonists and inhaled corticosteroids can be used as maintenance therapy by patients with moderate to severe chronic obstructive pulmonary disease. These interventions are often taken together in a combination inhaler.

Mitigating Thermal Runaway in Lithium Metal Batteries With Flame‐Retardant Magnesium Hydroxide Nanocomposite Gel Electrolytes

open access: yesAdvanced Energy Materials, EarlyView.
Lithium‐ion batteries are ubiquitous but pose significant safety risks especially with high‐energy‐density electrode materials. This study reports a nanocomposite gel electrolyte (NGE) with a flame‐retardant magnesium hydroxide (MH) matrix, which offers robust mechanical properties, high ionic conductivity, and enhanced thermal safety.

Grave to Cradle: A Direct Recycling Approach for Over‐Discharged LiFePO4 Electric Vehicle Cells

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The change in the LiFePO4 (LFP) material from grave to cradle. The material is delaminated with water, before undergoing ball milling and a relithiation‐carbothermal treatment. The final step shows the fully healed LFP remanufactured as a new cathode. The purple represents LiFePO4, the light purple FePO4, black, and dark grey—the graphite and carbons ...

Combinatorial Nb‐Doped TiO2 Wafers: Phase‐Defect Coengineering for Efficient and Reusable Photocatalysis

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Combinatorial Nb‐doped TiO2 wafers with a lateral dopant gradient enable rapid mapping of how phase composition and defects influence photocatalytic activity. Optimized Nb content generates mixed anatase–rutile phases together with beneficial Ti3+ and oxygen vacancy defects, boosting dye‐degradation efficiency fivefold.
