Improving energy production by boosting singlet fission process

Singlet fission (SF) is an exciton amplification phenomenon in which two triplet excitons are generated from a singlet exciton produced by the absorption of a single photon in chromophores. A team of researchers has demonstrated that SF can be promoted by introducing chirality and controlling chromophore orientation and arrangement. Their innovative study is expected to promote diverse applications in energy science, quantum, and information materials science, photocatalysis, solar cells, and life science.

New Huntington's treatment prevents protein aggregation

Patients with Huntington's disease have a genetic mutation that triggers proteins to misfold and clump together in the brain. These clumps interfere with cell function and eventually lead to cell death. The new treatment leverages peptide-brush polymers, which act as a shield to prevent proteins from binding to one another. In studies in mice, the treatment successfully rescued neurons to reverse symptoms.

Microplastics increasing in freshwater, directly related to plastic production

Microplastics have been steadily increasing in freshwater environments for decades and are directly tied to rising global plastic production since the 1950s, according to a new study by an interdisciplinary team. The findings provide insight into how microplastics move and spread in freshwater environments, which could be important for creating long-term solutions to reduce pollution, the researchers said.
