Long-term recording of single-neuron membrane voltage dynamics during behavior is highly desirable. Using ElectraOFF, a fully genetically encoded, photostable, high-performance fluorescence voltage indicator, we achieve routine cellular-resolution imaging over tens of minutes, occasionally up to eighty minutes, in behaving mice with minimal signal loss across neuron types and brain regions. This extended recording capability reveals plasticity changes throughout intracranial electrical neuromodulation, highlighting the novel insights enabled by prolonged voltage imaging.

Superlinear photodetectors hold significant potential in intelligent optical detection systems, such as near-field imaging. However, their current realization imposes stringent requirements on photosensitive materials, thereby limiting the flexibility of the device integration for practical applications. Herein, a tunable superlinear GaO deep-ultraviolet gate-all-around (GAA) phototransistor based on a p-n heterojunction has been proposed.

For optoelectronic devices based on lead-halide perovskites and other semiconductors, a comprehensive understanding of the electric field influences on the carrier transport characteristics is critical to the optimization of their practical performances. To fulfill this challenging goal, here we have employed photoluminescence spatial image and transient absorption microscopy measurements on an individual CsPbBr microplate biased at external voltages in an Au/CsPbBr/Au device. At the subpicosecond time scale, some photogenerated excitons are dissociated into free electrons and holes that drift toward the electrodes to leave behind unfilled defect sites, which are capable of scattering the residual excitons to yield a reduced diffusion coefficient.

A nanosecond pulse transient plasma is employed to initiate and control the exothermic decomposition of ionic liquids, namely, a mixture of hydroxylammonium nitrate (HAN) and 1-ethyl-3-methylimidazolium ethyl sulfate [EMIM]/[EtSO], as well as some noncombustible ionic liquids. Here, the plasma is discharged in a cylindrical geometry with a coaxial center wire electrode. High voltage (20 kV) nanosecond pulses (20 ns) at various frequencies up to 10 kHz produce a plasma discharge in the ionic liquid that initiates its nonthermal decomposition.

Molybdenum disulfide (MoS) has recently emerged as a promising material for the development of triboelectric nanogenerators (TENGs) owing to its inherently negative triboelectric properties when paired with polymeric layers, along with its notable transparency and mechanical flexibility. However, MoS-based TENGs operating in the contact-separation mode encounter critical limitations, including mechanical wear and limited triboelectric performance, particularly within the constraints of conventional 2D geometries. This paper reports the novel one-step laser-assisted synthesis of hemispherical MoS through the controlled nucleation and growth of MoS precursor seeds.

ObjectivesThe objective of this study was to evaluate the occurrence of voltage-gated potassium channel (VGKC) antibodies and the pattern of MRI changes in cats with complex partial seizures with orofacial involvement (CPSOFI), as well as to investigate whether there are factors influencing survival that could be used as prognostic markers in those cats.MethodsCats with CPSOFI were identified retrospectively. The following data were retrieved from the hospital database: signalment, age at first seizure and presentation, the presence of antibodies against VGKC (leucine-rich glioma inactivating factor 1 (LGI1), contactin-associated protein 2 (CASPR2)) and cerebrospinal fluid (CSF) analysis findings.
