Easy Diameter Tuning of Silicon Nanowires with Low-Cost SnO-Catalyzed Growth for Lithium-Ion Batteries.

Silicon nanowires are appealing structures to enhance the capacity of anodes in lithium-ion batteries. However, to attain industrial relevance, their synthesis requires a reduced cost. An important part of the cost is devoted to the silicon growth catalyst, usually gold.

Effect of Size and Shape on Electrochemical Performance of Nano-Silicon-Based Lithium Battery.

Silicon is a promising material for high-energy anode materials for the next generation of lithium-ion batteries. The gain in specific capacity depends highly on the quality of the Si dispersion and on the size and shape of the nano-silicon. The aim of this study is to investigate the impact of the size/shape of Si on the electrochemical performance of conventional Li-ion batteries.

A Scalable Silicon Nanowires-Grown-On-Graphite Composite for High-Energy Lithium Batteries.

Silicon (Si) is the most promising anode candidate for the next generation of lithium-ion batteries but difficult to cycle due to its poor electronic conductivity and large volume change during cycling. Nanostructured Si-based materials allow high loading and cycling stability but remain a challenge for process and engineering. We prepare a Si nanowires-grown-on-graphite one-pot composite (Gt-SiNW) a simple and scalable route.

Migratory foreign body of neck in a battered baby: a case report.

Only a small number of ingested foreign bodies perforate the esophagus and even smaller fraction migrate extramucosally with no symptoms. Both of these events are even rarer after marble ingestion. We report here a case of battered baby with homicidal marble ingestion which perforated the esophagus and migrated into the soft tissue of neck.

Sudden sensorineural hearing loss: have we got a cure?

Objective: To determine the efficacy of the shotgun regimen and to assess the various prognostic variables affecting recovery in patients with sudden sensorineural hearing loss (SSNHL).

Material And Methods: A prospective study of 42 patients with SSNHL was done. The selected patients received oral prednisolone at a dose of 1 mg/kg body weight tapered over 2 weeks and percutaneous application of 10 mg nitroglycerine for 1 week.

Thyroid gland in carcinoma of the larynx and hypopharynx: analysis of factors indicating thyroidectomy.

Background: This prospective study analyzed the factors that could predict thyroid gland involvement in patients suffering from malignancy of the larynx and laryngopharynx.

Methods: Fifty patients underwent total laryngectomy with either ipsilateral hemithyroidectomy or total thyroidectomy in cases with subglottic extent more than 1.5 cm or in patients undergoing total laryngopharyngectomy for hypopharyngeal malignancy.

Angiolipoma presenting as a nasal mass: how rare a presentation?

Angiolipomas are benign adipose tumors. There are two types: infiltrating and noninfiltrating. An angiolipoma presenting as a nasal mass is rare.

Leiomyosarcoma of the larynx: case report and review of the literature.

Leiomyosarcoma of the larynx is an extremely rare entity. This tumor is aggressive and is associated with dismal treatment results. We present a case of leiomyosarcoma of the larynx treated with surgery and postoperative radiotherapy.

Combination antifungal therapy for invasive aspergillosis: can it replace high-risk surgery at the skull base?

Objective: The increasing volume of literature on Aspergillus sinus infection is confusing because different authors stress different aspects of the disease. It is generally accepted that standard therapy consists of surgical debridement and medication with systemic amphotericin B. Patients who fail the standard therapy or those who cannot tolerate amphotericin B pose a dilemma.

Localized amyloidosis masquerading as nasopharyngeal tumor: a review.

Amyloidosis comprises a diverse collection of disease characterized by the presence of amorphous extracellular eosinophilic deposits of unique protein fibrils that gives apple green birefringence under polarized light after staining with Congo red. Head and neck region is the commonest site for localized form of amyloidosis. We report a case of a 43-year-old man with localized amyloidosis of nasopharynx with oropharyngeal extension and its management, along with a review of relevant literatures.

Epithelioid hemangioendothelioma of middle ear masquerading as glomus tumor.

Hemangioendothelioma is still one of the less-known tumors of vascular origin. The authors report the case of a 38-year-old man who presented with unilateral, nonpulsatile timnitus, aural fullness, and a sense of imbalance. Imaging showed a contrast enhancing soft tissue mass lesion involving the external auditory canal and middle ear, mimicking as glomus tumor.

Allergic fungal rhinosinusitis: an attempt to resolve the diagnostic dilemma.

Objective: To resolve the diagnostic dilemma of allergic fungal rhinosinusitis (AFRS), an increasingly recognized type of chronic rhinosinusitis (CRS). In spite of extensive studies, controversy exists regarding the etiologic characteristics, pathogenesis, and diagnosis of this entity.

Design: Prospective, comparative study.
