Hive-shaped carbon nanotubes coated with MoSeas an electrochemical sensor for cholesterol.

The study utilized transition metal chalcogenide, molybdenum diselenide (MoSe), for application in the field of bioelectrochemical sensing. The MoSewas combined with carbon nanotubes (CNTs) by chemical vapor deposition to enhance the specific surface area and improve the detection sensitivity. To further increase the contact area between the electrolyte and the electrode, photolithography techniques were employed to fabricate hive-shaped CNTs, thereby enhancing the specific surface area.

Association of Areca Nut Chewing With Risk of Erectile Dysfunction.

Introduction: Areca nut chewing has been shown to increase the risk of cardiovascular disease, but its association with erectile dysfunction (ED) has not been investigated.

Aim: To investigate the association between areca nut chewing and risk of ED.

Methods: Consecutive men at public health centers for oral malignancy screening or health checkup were invited to complete a questionnaire.

The Impact of Illicit Use of Amphetamine on Male Sexual Functions.

Introduction: Data concerning the impact of amphetamine on male sexual functions are limited, although amphetamine has been used as an aphrodisiac.

Aims: This cross-sectional study was to assess the impact of illicit use of amphetamine on male sexual functions.

Methods: Male illicit drug users in a Drug Abstention and Treatment Center were recruited to complete a self-administered questionnaire, and data were compared with age-matched controls.

Patterned growth of carbon nanotubes over vertically aligned silicon nanowire bundles for achieving uniform field emission.

A fabrication strategy is proposed to enable precise coverage of as-grown carbon nanotube (CNT) mats atop vertically aligned silicon nanowire (VA-SiNW) bundles in order to realize a uniform bundle array of CNT-SiNW heterojunctions over a large sample area. No obvious electrical degradation of as-fabricated SiNWs is observed according to the measured current-voltage characteristic of a two-terminal single-nanowire device. Bundle arrangement of CNT-SiNW heterojunctions is optimized to relax the electrostatic screening effect and to maximize the field enhancement factor.
