The characteristic absorption bands disappear and the shortest band at approximately 244 nm in cyclohexane or 282 nm in toluene remained only with long smoothing tail as C60 reacts adequately with aliphatic amines under sunlight radiation at approximately 40 degrees C. Simultaneously, fluorescence emission shifts from a weak band initially at longer wavelength to another strong one finally at shorter wavelength. The results might imply that the pi-conjugation system of C60 parent molecule is isolated into smaller separated parts. Therefore, some possible isolation models associated with observed experimental results are designed under some reasonable assumptive conditions.

The mechanical responses of sandy soil under dynamic loading is closely related to protective engineering and geotechnical engineering, is still not fully understood. To investigate the energy attenuation law and propagation velocity of compressed waves in dry sandy soil, this paper focuses on the dynamic response of compression waves in the specimen under single impact and repetitive impact conditions using an improved split Hopkinson pressure bar (SHPB). The results reveal that the length of the specimen follows an exponential relationship with the attenuation of the peak stress.

Hepatitis C virus (HCV) presents a significant global health issue due to its widespread prevalence and the absence of a reliable vaccine for prevention. While significant progress has been achieved in therapeutic interventions since the disease was first identified, its resurgence underscores the need for innovative strategies to combat it. The nonstructural protein NS5A is crucial in the life cycle of the HCV, serving as a significant factor in both viral replication and assembly processes.

Due to the high cost of each experimental run in additive manufacturing (AM), there has been a drive to develop simulations that can find the optimal processing parameters. The accuracy of these simulations is dependent on the accuracy of the material parameters recorded in literature. These reported parameters can vary widely resulting in differing simulation results.

The approval of Epidiolex, an anti-epileptic drug containing cannabidiol (CBD) as its active component, has brought hope to patients with refractory epilepsy. However, the anti-seizure effect of full-spectrum hemp extract (HE), a CBD-enriched hemp oil, remains unclear. In this study, we investigated the anti-seizure effect of HE using drug-induced seizure models.

Static magnetic field (SMF), an innovative and eco-friendly technology, has attracted widespread attention in the field of modified starch physicochemical properties. This study aimed to investigate the effects of SMF treatment on the structural and digestive properties of germinated corn (GC) starch. In vitro digestibility examination of GC starch revealed that SMF treatment (30 mT, 2 h) led to a 12.
