The review summarizes our recent reports on brightly-emitting materials with varied dimensionality (3D, 2D, 0D) synthesized using "green" chemistry and exhibiting highly efficient photoluminescence (PL) originating from self-trapped exciton (STE) states. The discussion starts with 0D emitters, in particular, ternary indium-based colloidal quantum dots, continues with 2D materials, focusing on single-layer polyheptazine carbon nitride, and further evolves to 3D luminophores, the latter exemplified by lead-free double halide perovskites. The review shows the broadband STE PL to be an inherent feature of many materials produced in mild conditions by "green" chemistry, outlining PL features general for these STE emitters and differences in their photophysical properties. The review is concluded with an outlook on the challenges in the field of STE PL emission and the most promising venues for future research.

The challenge of "false positive" signals significantly complicates tumor localization and surgical resection, which are pivotal for successful tumor surgeries. Therefore, the development of a method for preoperative tumor localization and intraoperative margin determination holds considerable promise for improving surgical outcomes. In this study, a zero-crosstalk ratiometric tumor-targeting near-infrared (NIR) fluorescent probe was developed for precise cancer diagnosis and intraoperative navigation via NIR fluorescence imaging.

Mechanistic understanding of the inhibitory immunoreceptor PD-1 is largely based on mouse models, but human and mouse PD-1 share only 59.6% amino acid identity. Here, we found that human PD-1 is more inhibitory than mouse PD-1, owing to stronger interactions with the ligands PD-L1 and PD-L2 and more efficient recruitment of the effector phosphatase Shp2.

Pd-based nanocatalysts hold significant promise for application in alkaline direct ethanol fuel cells (DEFCs). To address the challenges of low Pd atom utilization and poor reaction kinetics in conventional Pd-based catalysts, a self-etching strategy has been developed to synthesize PdPb nanoparticles (NPs) with tunable size and abundant tensile strain. The nanoparticles demonstrated a markedly enhanced electrocatalytic performance.

Background: Asymptomatic Alzheimer's disease (AsymAD) refers to individuals with preserved cognition but identifiable Alzheimer's disease (AD) brain pathology, including beta-amyloid (Aβ) deposits, neuritic plaques and neurofibrillary tangles upon autopsy. Unlike AD cases, AsymAD exhibits low neuroinflammation and fewer soluble pathological tau species at synaptic levels. However, the link between these observations and the ability to counteract AD pathology is not fully understood.

Background: Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by the deposition of amyloid-beta and hyperphosphorylated tau (P-tau) proteins in the brain. P-tau accumulates in neurons and is strongly associated with AD severity and affected brain regions. However, only a subset of neurons in AD exhibit tau pathology.
