Dopant Control of Solution-Processed CuI:S for Highly Conductive p-Type Transparent Electrode.

Copper iodide (CuI) has garnered considerable attention as a promising alternative to p-type transparent conducting oxides owing to its low cation vacancy formation energy, shallow acceptor level, and readily modifiable conductivity via doping. Although sulfur (S) doping through liquid iodination has exhibited high efficacy in enhancing the conductivity with record high figure of merit (FOM) of 630 00 MΩ, solution-processed S-doped CuI (CuI:S) for low-cost large area fabrication has yet to be explored. Here, a highly conducting CuI:S thin-film for p-type transparent conducting electrode (TCE) is reported using low temperature solution-processing with thiourea derivatives.

Experience of hemostasis in tracheal bleeding very close to the carina by the bronchial blocker: a case report.

Massive hemoptysis is respiratory compromise which should be managed as a life-threatening condition. In our case, the bronchial blocker played a role in hemostasis of tracheal bleeding very close to the carina and prevented further spillage into the contralateral lung. Right-sided one-lung isolation in an 87-year-old female, who received cardiopulmonary resuscitation due to myocardial infarction, was requested due to hemoptysis.

Vertebrobasilar occlusion presenting as sudden isolated bilateral sensorineural hearing loss: case report.

Isolated bilateral deafness is a rare but possible symptom of vertebrobasilar ischemia, primarily due to occlusion of the anterior inferior cerebellar arteries or their branch, the internal auditory artery. We reported on uncommon case of sudden bilateral sensorineural hearing loss without typical neurological symptoms resulting from vertebrobasilar ischemia. We performed the available examinations, including otoscopy, laboratory tests, and pure tone audiogram, however we were not able to identify the cause of bilateral sensorineural hearing loss.
