Challenges and Strategies of Aluminum Anodes for High-Performance Aluminum-Air Batteries.

Aluminum-air battery (AAB) is a promising candidate for next-generation energy storage/conversion systems due to its cost-effectiveness and impressive theoretical energy density of 8100 Wh kg, surpassing that of lithium-ion batteries. Nonetheless, the practical applicability of AABs is hampered by the occurrence of serious self-corrosion side reactions and substantial capacity loss, resulting in suboptimal anode utilization. Consequently, improving the anode utilization to facilitate the construction of high-performance AABs have attracted widespread attention.

A case report of a brain abscess due to prevotella oris and a review of the literature.

Background: Brain abscesses caused by Prevotella oris are rarely reported. Here, we described a case of a brain infection caused by Prevotella oris that was detected by metagenomic next-generation sequencing (mNGS).

Case Presentation: A 63-year-old man with no medical history reported headache in the right frontotemporal region, fever, and intermittent diplopia.

Quasi-Solid-State Aluminum-Air Batteries with Ultra-high Energy Density and Uniform Aluminum Stripping Behavior.

Aqueous aluminum-air batteries are attracting considerable attention with high theoretical capacity, low-cost and high safety. However, lifespan and safety of the battery are still limited by the inevitable hydrogen evolution reaction on the metal aluminum anode and electrolyte leakage. Herein, for the first time, a clay-based quasi-solid-state electrolyte is proposed to address such issues, which has excellent compatibility and a liquid-like ionic conductivity.

Regulating solvation and interface chemistry enables advanced aluminum-air batteries.

The main challenge for developing aqueous aluminum-air batteries with high mass-specific capacity depends on the inhibition of the parasitic hydrogen evolution reaction. Herein, a regulation strategy of solvation and interface chemistry has been proposed by introducing organic methylurea (MU) and inorganic stannous chloride (SnCl) to the alkaline electrolyte, which can modulate the solvent structure and electrode/electrolyte interface and endow the aqueous aluminum-air battery with an outstanding mass-specific capacity of 2625 mA h g at 50 mA cm.

Revealing the Two-Dimensional Surface Diffusion Mechanism for Zinc Dendrite Formation on Zinc Anode.

Aqueous zinc-ion battery is regarded as one of the promising devices for large-scale energy storage systems owing to its high safety, cost-effectiveness, and competitive electrochemical properties. However, the dendrite growth on zinc metal anodes dramatically hinders its further practical applications, and the internal mechanism of dendrite evolution is still unclear. The introduction of a protective layer on the anode interface is an effective method to avoid zinc dendrite growth.

Long-Term DL-3--Butylphthalide Treatment Alleviates Cognitive Impairment Correlate With Improving Synaptic Plasticity in SAMP8 Mice.

Alzheimer's disease (AD) is the most prevalent form of dementia worldwide. AD is characterized by mild cognitive impairment at onset, irreversibly progressing with age to severe neurodegeneration and cognitive deficits in the late stages. Unfortunately, no effective treatments exist to prevent or delay the cognitive symptoms of AD.

Effects of eldepryl on glial cell proliferation and activation in the substantia nigra and striatum in a rat model of Parkinson's disease.

Objectives: Inflammation is involved in the occurrence and progression of Parkinson's disease (PD), but the exact mechanisms remain unclear. This study aimed to observe the expressions of glial fibrillary acidic protein (GFAP) and integrin αM (CD11b) in the substantia nigra and striatum, and to investigate the effect of eldepryl on these expressions in a rat model of PD.

Methods: Seventy-two rats were randomly divided into three groups: control, model, and eldepryl.

The Role of Hippocampal Structural Synaptic Plasticity in Repetitive Transcranial Magnetic Stimulation to Improve Cognitive Function in Male SAMP8 Mice.

Background: Repetitive transcranial magnetic stimulation (rTMS) has been used to improve cognitive function, but the stimulation protocols are variable and the underlying mechanism is unclear. Therefore, we intend to examine whether 5Hz rTMS with 30% maximum output could improve cognitive functions in senescence-accelerated-prone mouse 8 (SAMP8) through changing synaptic plasticity.

Methods: SAMP8 and senescence-accelerated-prone mouse/resistant 1 (SAMR1) (7-month old male) were randomly divided into 3 groups: SMAP8 rTMS group (P8-rTMS), SMAP8 sham-rTMS group (P8-sham), and SAMR1 sham-rTMS group (R1-sham).

Autophagy-related protein expression in the substantia nigra and eldepryl intervention in rat models of Parkinson's disease.

Autophagy has been shown to participate in the pathogenesis of Parkinson's disease (PD), but its precise mechanism remains poorly understood. This study observed autophagy, autophagy-related protein Beclin1 and microtubule-associated protein 1 light chain 3 (LC3) expression in substantia nigra, and eldepryl effects on their expression, as well as explored autophagy effects on the onset of PD and the mechanism of action of eldepryl on PD in rat models. Models of PD were established by subcutaneous injection of rotenone through back of the neck.
