High Mobility Indium Oxide Electron Transport Layer for an Efficient Charge Extraction and Optimized Nanomorphology in Organic Photovoltaics.

The electron transport layer (ETL) plays an important role in determining the device efficiency of organic solar cells (OSCs). A rational design of an ETL for OSCs targets high charge extraction and induction of an optimized active layer morphology. In this Letter, a high mobility InO synthesized via a solution-processed combustion reaction is successfully used as a universal ETL in an organic photovoltaic device.

[Oral health-related quality of life in patients with fixed appliances].

Objective: To assess oral health-related quality of life in patients with fixed appliances.

Methods: Orthodontic patients were asked to complete the scale of general conditions (Chinese version, questionnaire 1) and oral health impact profile (OHIP) -14 (Chinese version, questionnaire 2). Baseline data were collected at first visit and thereafter.

[Treatment of maxillary protrusion in adult with self-tapping micro-screw implants].

Objective: To investigate the position change of upper molars and incisors in order to evaluate the stability of posterior anchorage with the application of micro-screw implant.

Methods: Eight adult patients with severe maxillary protrusion were included. Upper first premolars were extracted and upper posterior anchorage was reinforced with micro-screw implant in all patients.

[First molar extraction in patients with crowding: cases analysis].

Objective: To evaluate the outcome of first molar extraction in patients with crowding.

Methods: Totally 22 patients (8 males and 14 females) from Clinic of Orthodontics, SUN Yat-sen University School of Stomatology with crowding were collected. The patients were aged 11 years 3 months to 26 years 8 months (mean age 16 years 6 months).
