Dynamics and coherence resonance in a thermosensitive neuron driven by photocurrent* Tập 29 Số 9 - Trang 098704 - 2020
Ying Xu, Minghua Liu, Zhigang Zhu, Jun Ma
A feasible neuron model can be effective to estimate the mode transition in
neural activities in a complex electromagnetic environment. When neurons are
exposed to electromagnetic field, the continuous magnetization and polarization
can generate nonlinear effect on the exchange and propagation of ions in the
cell, and then the firing patterns can be regulated completely. The conductivity
of ion ch... hiện toàn bộ
A novel plasmonic refractive index sensor based on gold/silicon complementary grating structure* Tập 30 Số 2 - Trang 024207 - 2021
Xiangxian Wang, Jiankai Zhu, Yueqi Xu, Yunping Qi, Liping Zhang, Hua Yang, Zao Yi
A novel complementary grating structure is proposed for plasmonic refractive
index sensing due to its strong resonance at near-infrared wavelength. The
reflection spectra and the electric field distributions are obtained via the
finite-difference time-domain method. Numerical simulation results show that
multiple surface plasmon resonance modes can be excited in this novel structure.

Surface-enhanced fluorescence and application study based on Ag-wheat leaves Tập 31 Số 3 - Trang 037803 - 2022
Hongwen Cao, Liting Guo, Zhen Sun, Tifeng Jiao, Mingli Wang
Wheat leaves with natural microstructures as substrates were covered by the
silver nanoislands by magnetron to prepare a low-cost, environment-friendly and
mass production surface-enhanced fluorescence (SEF) substrate (Ag-WL substrate).
The best SEF substrate was selected by repeatly certifying the fluorescence
intensity of 10−5 M Rhodamine B (RB) and 10−5 M Rhodamine 6G (R6G) aqueous
solutions. T... hiện toàn bộ
