A Bias-Tunable Multispectral Photodetector Based on a GaN/TeSe Homo-Type Heterojunction with a Unidirectional Barrier.

Multispectral detection technology captures characteristic spectral information across various wavebands, exhibiting substantial application potential.

In this study, a bias-tunable multispectral photodetector featuring a straightforward single-junction design is introduced.

Impact of combined ultrasonic and microwave vacuum drying on physicochemical properties and structural characteristics of polysaccharides from shiitake mushrooms (Lentinus edodes).

In this study, ultrasonic technology was combined with microwave vacuum drying technology to explore the impacts of different coupling methods (ultrasonic pretreatment and ultrasonic coupled drying) on the structural characterisation and physicochemical properties of shiitake mushroom (Lentinus edodes) polysaccharides at different ultrasonic powers (0, 120 and 280 W), and compared with hot air drying (HAD).

Combined addition of L-carnitine and L-proline improves cryopreservation of dairy goat semen.

Cryopreservation of semen renders artificial insemination easier and cheaper compared to use of fresh semen. However, the cellular oxidative stress, toxicity of cryoprotectants, and osmotic imbalance may lead to a decline in semen quality and fertilization ability during the process of cryopreservation. L-carnitine and L-proline have been demonstrated to possess effective antioxidant properties in cryopreservation, with the latter also exhibiting excellent permeability and thus being utilized as a permeable cryoprotectant in the field.
