Highly Conductive Polyoxanorbornene-Based Polymer Electrolyte for Lithium-Metal Batteries.

This present study illustrates the synthesis and preparation of polyoxanorbornene-based bottlebrush polymers with poly(ethylene oxide) (PEO) side chains by ring-opening metathesis polymerization for solid polymer electrolytes (SPE). In addition to the conductive PEO side chains, the polyoxanorbornene backbones may act as another ion conductor to further promote Li-ion movement within the SPE matrix. These results suggest that these bottlebrush polymer electrolytes provide impressively high ionic conductivity of 7.

Prediction of hearing outcomes by auditory steady-state response in patients with sudden sensorineural hearing loss.

Background: There has been no report on the predictive value of auditory steady-state response (ASSR) in the hearing prognosis of sudden sensorineural hearing loss (SSNHL).

Aims/objectives: To investigate whether ASSR can be a prognostic indicator of hearing outcome in patients with SSNHL after systemic steroid treatment.

Material And Methods: Fifty-three patients with unilateral mild to severe SSNHL (≤90 dB HL at 0.

Persistent static imbalance among acute unilateral vestibulopathy patients could be related to a damaged velocity storage system.

Acute unilateral vestibulopathy (AUV) is common but, the course of disease recovery is variable. Moreover, the final recovery status might vary between subjects. The remaining symptoms of these patients indicate the poor recovery of static imbalance, which could limit social activities and decrease their quality of life.
