High-efficiency small-molecule ternary solar cells with a hierarchical morphology enabled by synergizing fullerene and non-fullerene acceptors

Abstract: Using combinatory photoactive blends is a promising approach to achieve high power conversion efficiency in ternary organic photovoltaics However, the fundamental challenge of how to manipulate th

Principles of biosensing with an extended coupling matrix and surface plasmon resonance

Abstract: Surface plasmon resonance is one of the surface-oriented biosensing techniques that can be used to monitor biomolecular interactions. It is utilized in instrumentation for real-time biospecific interaction analysis capable of determining not only the concentrations of biomolecules but also kinetic constants, binding specificity, etc. In this contribution biosensing with surface plasmon resonance is reviewed. Special attention is given to an extended interaction matrix on the sensing surface, which enables the covalent binding of, e.g., antigens or antibodies. The surface plasmon resonance angle shifts are calculated as a function of the amount of organic material in the matrix. The influence of physical parameters, such as matrix thickness and wavelength of the light, on the expected performance is considered. Finally, a few illustrative experimental results obtained with a recently introduced commercial instrument are given.

Methods for epidemiological study of injuries to professional football players: developing the UEFA model

Abstract: A problem with epidemiological studies of football injuries is the inconsistent manner in which injury is defined and data are collected. Projects have been initiated to study the incidence and causes of injury in football, but there is no uniformly accepted reporting system. In this report, some common pitfalls encountered in the recording of injury are addressed, and practical guidelines for epidemiological studies are provided. An injury reporting system developed for the UEFA Football Safety Project for studies on professional footballers is used as a starting point for a general discussion on injury registration and compared with other existing reporting systems. The recording definition of injury may vary between studies depending on its purpose. A time loss injury definition is practical for all playing levels, and, as a minimum, results on time loss injuries should therefore always be reported separately to allow direct comparisons between studies. There is a need to agree on a uniform sports injury classification system with corresponding diagnostic criteria, as well as standardised return to play criteria after injury.
