Atmospheric Pressure Catalytic Vapor Deposition of Graphene on Liquid Sn and Cu-Sn Alloy Substrates.

The chemical vapor deposition (CVD) of graphene on liquid substrates produces high quality graphene films due to the defect-free and atomically flat surfaces of the liquids. Through the detailed study of graphene growth on liquid Sn using atmospheric pressure CVD (APCVD), the quality of graphene has been found to have a close relationship with hydrogen flow rate that reflects on hydrogen partial pressure inside the reactor (P) and hydrogen solubility of the growth substrates. The role of P was found to be crucial, with a low defect density monolayer graphene being obtained in low P (90.

The role of optimum diabetes care in form of Ramadan focused diabetes education, flash glucose monitoring system and pre-Ramadan dose adjustments in the safety of Ramadan fasting in high risk patients with diabetes.

Background: Physiology of intermittent and prolonged fasting is known from healthy subjects. Evidence on high and very high-risk groups is lacking. The anticipated risks include hypoglycemia, hyperglycemia, dehydration and thrombosis.

Safety of Sodium-Glucose Cotransporter 2 Inhibitors (SGLT2-I) During the Month of Ramadan in Muslim Patients with Type 2 Diabetes.

Objectives: Sodium-glucose cotransporter 2 inhibitors (SGLT2-I) are a new class of antidiabetic drugs that might increase the risk of dehydration and hypoglycemia, particularly during the month of Ramadan in which Muslims abstain from eating and drinking for 14-16 hours daily. We aimed to provide real-life evidence about the safety of SGLT2-I during Ramadan.

Methods: All patients over the age of 18 years on SGLT2-I before Ramadan 2016 who would be fasting during Ramadan were included.
