Hydrogen Production Using TiO2-Based Photocatalysts: A Comprehensive Review

Titanium dioxide (TiO2) is one of the most widely used photocatalysts due to its physical and chemical properties. In this study, hydrogen energy production using TiO2- and titanate-based photocatalysts is discussed along with the pros and cons. The mechanism of the photocatalysis has been elaborated to pinpoint the photocatalyst for better performance. The chief characteristics and limitations of the TiO2 photocatalysts have been assessed. Further, TiO2-based photocatalysts modified with a transition metal, transition metal oxide, noble metal, graphitic carbon nitride, graphene, etc. have been reviewed. This study will provide a basic understanding to beginners and detailed knowledge to experts in the field to optimize the TiO2-based photocatalysts for hydrogen production

Combined oral contraceptives and their impact on lipids, blood pressure, and body mass index in pregnant women

Objective: To determine how combination oral contraceptive pills (COCPs) affect women of reproductive age's lipid profiles, blood pressure, and body mass index. Methodology: This cross-sectional study looked at the family planning programmes at the tertiary referral hospitals in Peshawar. We looked at married, childbearing women (aged 14 to 49). Group 1 (those who had used COCPs for at least six months) and Group 2 (controls of a comparable age who had not used COCPs) were created. Fasting blood TC, TG, HDL-C, LDL-C, and VLDL-C levels were assessed using a chemical analyser. Hb and platelet levels were assessed by a haematology analyst. Everyone had their BMI and blood pressure measured. The parameters of the oral and control groups were compared using SPSS. Results: The average BMI of Group 1 (Oral COCP) was 28.12 kg/m2 (+/- 0.50 SEM), while the average BMI of Group 2 (Control) was 26.25 kg/m2 (+/- 0.43 SEM). The mean BMIs of the two groups were very different (p-value: 0.0003). Women in Group 1 who took combined oral contraceptives had a much higher BMI than women in Group 2 who did not. BMI is used to measure health. It is based on height and weight.&nbsp
