High-entropy materials (HEMs) have recently emerged as a prominent research focus in materials science, gaining considerable attention because of their complex composition and exceptional properties. These materials typically comprise five or more elements mixed approximately in equal atomic ratios. The resultant high-entropy effects, lattice distortions, slow diffusion, and cocktail effects contribute to their unique physical, chemical, and optical properties.

Today's computing systems, to meet the enormous demands of information processing, have driven the development of brain-inspired neuromorphic systems. However, there are relatively few optoelectronic devices in most brain-inspired neuromorphic systems that can simultaneously regulate the conductivity through both optical and electrical signals. In this work, the Au/MXene/Y:HfO/FTO ferroelectric memristor as an optoelectronic artificial synaptic device exhibited both digital and analog resistance switching (RS) behaviors under different voltages with a good switching ratio (>10).

Article Synopsis
  • G. lucidum (Lingzhi) is a traditional Chinese medicinal mushroom known for treating diseases like Alzheimer's and mood disorders; recent studies show its sporoderm-removed spore extract (RGLS) may help alleviate learning deficits and depression in rat models.
  • In experiments with rats exposed to ICV-STZ to induce depression, RGLS significantly improved depression- and anxiety-like behaviors, indicating its protective effects.
  • The study revealed that RGLS works by reducing neuroinflammation in the brain, specifically by modulating the NF-κB/NLRP3 inflammatory pathway, and promoting synaptic health through increased brain-derived neurotrophic factor levels.

  • A study investigated the effects of RGLS spore extract on sleep disturbances and cognitive impairments in a rat model of sporadic Alzheimer's disease (sAD).
  • Treatment with 720 mg/kg of RGLS for 14 days significantly increased total sleep time and improved both REM and non-REM sleep in sAD rats while also preventing memory deficits.
  • The research suggests that RGLS may work by inhibiting neuroinflammatory pathways and enhancing GABAergic neuron activity, offering insights into its potential benefits for cognitive function and sleep quality in Alzheimer's disease.

The conventional von Neumann architecture has proven to be inadequate in keeping up with the rapid progress in artificial intelligence. Memristors have become the favored devices for simulating synaptic behavior and enabling neuromorphic computations to address challenges. An artificial synapse utilizing the perovskite structure PbHfO (PHO) has been created to tackle these concerns.

Compared with purely electrical neuromorphic devices, those stimulated by optical signals have gained increasing attention due to their realistic sensory simulation. In this work, an optoelectronic neuromorphic device based on a photoelectric memristor with a BiFeCrO/Al-doped ZnO (BFCO/AZO) heterostructure is fabricated that can respond to both electrical and optical signals and successfully simulate a variety of synaptic behaviors, such as STP, LTP, and PPF. In addition, the photomemory mechanism was identified by analyzing the energy band structures of AZO and BFCO.

Resistive random-access memory (RRAM) is a promising candidate for next-generation non-volatile memory. However, due to the random formation and rupture of conductive filaments, RRMS still has disadvantages, such as small storage windows and poor stability. Therefore, the performance of RRAM can be improved by optimizing the formation and rupture of conductive filaments.

Adhesion between flexible devices and skin surface facilitates portability of devices and reliable signal acquisition from human body, which is essential for medical therapy devices or monitoring systems. Here, we utilize a simple, cost-effective, and scalable layer-by-layer dip-coating method to fabricate a skin-adhesive multifunctional textile-based device, consisting of three parts: low-cost and easily available airlaid paper (AP) substrate, conductive MXene sensitive layer, and adhesive polydimethylsiloxane (PDMS). The adhesive layer of lightly cross-linked PDMS enables the device to form conformal contact with skin even during human joint bending.

Innate and adaptive immune factors play significant roles in the pathophysiology of endometriosis. T helper 17 (Th17) cells, a pro-inflammatory T cell subset, were considered to contribute to the progression of endometriosis lesions. However, the regulatory mechanisms of Th17 cells in endometriosis remain unidentified, partially due to the difficulty in recovering live Th17 cells from endometriosis patients.
