Quantitative study on objective indicators for assessing motion sickness susceptibility based on Vestibulo-Ocular Reflex experiments.

Motion sickness (MS) is a common physiological response that often occurs when individuals are exposed to environments with repeated acceleration stimuli. MS results from a mismatch between the vestibular system and visual and proprioceptive inputs. As a crucial organ for sensing acceleration stimuli, the vestibular system is closely related to the onset of MS.

Enhanced device performance and stability of perovskite solar cells with low-temperature ZnO/TiO bilayered electron transport layers.

The instability of perovskite films is a major issue for perovskite solar cells based on ZnO electron transport layers (ETLs). Here, ZnO nanoparticle (NP)- and ZnO sol-gel layers capped with low-temperature processed TiO, namely ZnO/TiO bilayered films, have been successfully employed as ETLs in highly efficient MAPbI-based perovskite solar cells. It is demonstrated that these ZnO/TiO bilayered ETLs are not only capable of enhancing photovoltaic performance, but also capable of improving device stability.

Towards understanding the initial performance improvement of PbS quantum dot solar cells upon short-term air exposure.

An initial improvement in performance of PbS quantum dot solar cells composed of one thick layer of PbS quantum dots (QDs) treated with tetrabutylammonium iodide (PbS-TBAI) and one thin layer of PbS QDs capped with 1,2-ethanedithiol (PbS-EDT) over short-term air exposure is widely observed. However, the underlying mechanisms still remain elusive. In the work, we sought to understand the mechanisms as well as their physicochemical origins using a combination of X-ray photoelectron spectroscopy (XPS) and various electronic measurements.
