Poly(curcumin-co-poly(ethylene glycol)) films provide neuroprotection following reactive oxygen species insult in vitro.

Curcumin is an antioxidant and anti-inflammatory molecule that may provide neuroprotection following central nervous system (CNS) injury. However, curcumin is hydrophobic, limiting its ability to be loaded and then released from biomaterials for neural applications. We previously developed polymers containing curcumin, and these polymers may be applied to neuronal devices or to neural injury to promote neuroprotection.

A circumpolar review of the breeding distribution and habitat use of the snow petrel (), the world's most southerly breeding vertebrate.

Knowledge of the spatial distribution of many polar seabird species is incomplete due to the remoteness of their breeding locations. Here, we compiled a new database of published and unpublished records of all known snow petrel breeding sites. We quantified local environmental conditions at sites by appending indices of climate and substrate, and regional-scale conditions by appending 30 year mean (1992-2021) sea-ice conditions within accessible foraging areas.

pBn type short-wavelength infrared photodetector with an ultralow dark current and extended wavelength based on a strained InGaAs/GaAsSb superlattice.

An InGaAs/GaAsSb type II superlattice (T2SL) absorber is a promising alternative material for a short-wavelength infrared (SWIR) photodetector due to the largely tunable bandgap by adjusting the thickness and material composition of InGaAs and GaAsSb in each T2SL period. We demonstrate a pBn type SWIR photodetector consisting of a strained InGaAs/GaAsSb T2SL absorber and AlGaAsSb barrier. The device presents an ultralow dark current density of 1.
