An ionic liquid incorporated in a quasi-solid-state electrolyte for high-temperature supercapacitor applications.

An ionic liquid (IL) incorporated in a quasi-solid-state electrolyte (ILQSE) is prepared using 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIBF) and poly (ethylene glycol dimethacrylayte) (PEGDMA) for high-temperature application of supercapacitors. The prepared ILQSE displays a thermal stability up to 150 °C and the supercapacitors exhibit a specific capacitance of 134 F g.

Multimodal porous carbon derived from ionic liquids: correlation between pore sizes and ionic clusters.

In this proof of concept study on the synthesis of ionic liquid (IL)-derived multimodal porous carbon using ionic clusters of different sizes as porogens, the carbonization behaviors of binary IL mixtures of 1-ethyl-3-methylimidazolium dicyanamide (EMIM-dca) and 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIM-TfN) were systematically investigated to demonstrate the formation of multimodal porous carbons with hierarchical structures originating from the ionic cluster porogens. The multimodal porous structures of the resulting IL-derived porous carbons were characterized based on the quenched solid density functional theory, and the role of the ionic clusters as porogens is discussed. From the viewpoint of green and sustainable chemistry, the IL-based synthesis using ionic clusters as porogens is a simple, effective, and sustainable technique for synthesizing multimodal porous carbons with hierarchical structures.

Graphene-Selenium Hybrid Microballs as Cathode Materials for High-performance Lithium-Selenium Secondary Battery Applications.

In this study, graphene-selenium hybrid microballs (G-SeHMs) are prepared in one step by aerosol microdroplet drying using a commercial spray dryer, which represents a simple, scalable continuous process, and the potential of the G-SeHMs thus prepared is investigated for use as cathode material in applications of lithium-selenium secondary batteries. These morphologically unique graphene microballs filled with Se particles exhibited good electrochemical properties, such as high initial specific capacity (642 mA h g(-1) at 0.1 C, corresponding to Se electrochemical utilisation as high as 95.

Neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio: novel markers for diagnosis and prognosis in patients with idiopathic sudden sensorineural hearing loss.

Background: We aim to provide useful evidence about the association of neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) with idiopathic sudden sensorineural hearing loss (ISSNHL) and its possibility of emerging as a cheap, reliable, and independent prognostic marker of ISSNHL.

Methods: 348 patients diagnosed with ISSNHL were included in our retrospective data analysis. Blood samples and the hearing assessments of the patients were carried out.

What really decides the facial function of vestibular schwannoma surgery?

Objectives: To find the main cause of facial nerve dysfunction in vestibular schwannoma (VS) surgery and review the prognosis of facial function in relation to tumor size, preoperative facial function and surgical approach.

Methods: We reviewed the surgical outcome of 134 patients with VS treated in our department between 1994 and 2008. All patients included in the study had postoperative facial paralysis after surgical management of their VS.

The extended indication of parotidectomy using the modified facelift incision in benign lesions: retrospective analysis of a single institution.

Background: Recently, the modified facelift incision (FLI) has gained increasing popularity for its cosmetic benefits in parotidectomy. However, many surgeons remain concerned with the adequacy of the exposure and are unwilling to use the FLI for anterior or superior tumors of the parotid gland because these tumors are closer to the superficially positioned facial nerve branch. To evaluate the changing trends in parotidectomy incisions for benign lesions at a single institute, and to compare the surgical outcomes between the modified Blair incision (BI) and FLI, and determine the adequacy and possible indications or limitations of the FLI, especially for tumors located in the anterior or superior parotid gland.

Radiotherapy deteriorates postoperative functional outcome after partial glossectomy with free flap reconstruction.

Purpose: Most patients with tongue cancer require surgical resection of the tongue to varying degrees. As a result, quality of life, which is strongly related to speech, chewing, and swallowing, can deteriorate severely from extensive surgical treatment of tongue cancer. In addition to surgery, adjuvant therapy may affect the severity of functional impairment.

Features of facial asymmetry following incomplete recovery from facial paralysis.

Purpose: The purpose of this study is to investigate peculiar patterns of facial asymmetry following incomplete recovery from facial paralysis that require optimal physical therapy for effective facial rehabilitation, and to decrease the incidence of avoidable facial sequelae.

Materials And Methods: This study involved 41 patients who had facial sequelae following the treatment of various facial nerve diseases from March 2000 to March 2007. All patients with a followup of at least 1 year after the onset of facial paralysis or hyperactive function of the facial nerve were evaluated with the global and regional House-Brackmann (HB) grading systems.
