An interdisciplinary research team from Dresden University of Technology (TUD), Rostock University Medical Centre (UMR) and Dresden University Hospital has developed an innovative, implantable and fully absorbable sensor film. For the first time, it enables reliable early detection of circulatory disorders in intestinal anastomoses – one of the riskiest surgical procedures in the abdominal cavity. The results have now been presented in the renowned journal ‘Advanced Science’.

Red-backed shrikes fly thousands of kilometres to reach Africa – and they do so with astonishing precision. Aided by new technology, researchers at Lund University in Sweden have been able to track the birds’ journeys in detail. It turns out that they may have a more complex genetic migration programme than researchers have previously been able to show.

Researchers report a molecular design strategy for high-voltage organic cathodes in aluminum batteries. By constructing a sulfur-heterocyclic polymer with weak electron-donating effect and super-crosslinked sites, the cathode achieves a high voltage of ~1.7 V and a high capacity of 150 mAh g⁻¹. The designed organic cathode achieves a record 255 Wh kg⁻¹ energy density, breaking the upper limit of conventional graphite cathodes (~200 Wh kg⁻¹).

A nonfused ring electron acceptor (NFREA), designated as TT-Ph-C6, has been synthesized with the aim of enhancing the power conversion efficiency (PCE) of organic solar cells (OSCs). By integrating asymmetric phenylalkylamino side groups, TT-Ph-C6 demonstrates excellent solubility and its crystal structure exhibits compact packing structures with a three-dimensional molecular stacking network. These structural attributes markedly promote exciton diffusion and charge carrier mobility, particularly advantageous for the fabrication of thick-film devices. TT-Ph-C6-based devices have attained a PCE of 18.01% at a film thickness of 100 nm, and even at a film thickness of 300 nm, the PCE remains at 14.64%, surpassing that of devices based on 2BTh-2F. These remarkable properties position TT-Ph-C6 as a highly promising NFREA material for boosting the efficiency of OSCs.
