High‐Performance, Air‐Stable and Eco‐Friendly Terpene‐Processed Organic Solar Cells via Solvent‐Composition‐Controlled Film Formation Kinetics

open access: yesAdvanced Functional Materials, EarlyView.
Solvent‐composition‐controlled film formation enables high‐performance (efficiency = 18.66%) and air‐stable terpene‐processed organic solar cells. An optimized eucalyptol/tetralin ratio of 50:50 (v/v) balances molecular solvation and aggregation kinetics, producing favorable nanoscale phase separation and vertical composition gradients.

Mechanistic Origins of Chemo‐Mechanical Instability and Failure in Solid‐State Lithium‐Sulfur Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Conversion‐induced sulfur expansion generates strong mechanical constraints and localized stresses within solid‐state Li‐S cathodes. Heterogeneous solid‐electrolyte confinement creates tensile strain‐energy hotspots that govern particle cracking. Larger sulfur particles accelerate fracture, while higher porosity relaxes constraint and delays damage ...

Lost to Follow-Up.

Lancet, The, 1967
Abstract " Lost to follow-up" means more than loss, it means failure to find. Some patients will be lost, the risk being higher in the long-term follow-up of young adults with curable disease. If these lost patients are not found, it is largely because adequate tracing data were not recorded during the hospital admission.

Lost to Follow-up-Reply

Archives of Ophthalmology, 1977
In Reply .–Ms Lang has made some important points. Tracing patients is in fact a difficult and time-consuming task. We are fortunate at the University of Iowa to have a very active Tumor Registry. The patients are contacted every six months the first two years and then once a year until death occurs; a death certificate is then obtained. The number of

Outcome in patients lost to follow-up

The Journal of Arthroplasty, 2003
Long-term outcome studies are valuable for providing information on the results of joint arthroplasty. However, a progressively increasing rate of attrition correlates with the length of study. The attrition rate of patients "lost to follow-up" ("non-attenders") may have a significant effect on the reported outcome.
