Article Synopsis
- The study aimed to evaluate the impact of chemical and structural characteristics of four bis-acryl resins (Luxatemp, Protemp, Structur, and Telio) on their fracture resistance in fixed prosthesis applications.
- Bending tests revealed that Luxatemp and Structur exhibited significantly higher flexural strength compared to Protemp and Telio, which showed lower strength.
- Additional analyses using scanning electron microscopy and infrared spectroscopy indicated that the unique particle size and chemical structure of Luxatemp contributed to its superior strength.

Article Synopsis
- * This study focused on testing Disordered Mesoporous Silica 1 (DMS-1) modified with amino groups for its ability to adsorb lead ions (Pb(II)), using a sol-gel method to prepare the material.
- * The best results for removing Pb(II) were obtained with a 0.3 molar ratio of amino groups, achieving a lead removal efficiency of 99.44%, indicating this method could be a promising solution for purifying contaminated water.

Article Synopsis
- Tridimensional cubic mesoporous silica, known as SBA-16, was modified with aminopropyl groups to enhance its ability to adsorb lead (Pb) ions from water.
- The effectiveness of the adsorbent was examined based on various factors, including pH level, contact time, temperature, and the concentration of the aminopropyl compound used in its functionalization.
- Results indicated that the best Pb ion removal occurred at a pH between 5-6, after 40 minutes of contact time, and with an initial lead concentration of 200 mg/L, making the optimized 2N-SBA-16 significantly more effective than another variant, SBA-15.

Article Synopsis
- SBA-15 is a mesoporous silica material known for its highly ordered nanopores and large surface area, making it useful in various applications like catalysts and drug delivery.
- To enhance its functionality, heteroatoms and organic groups are added through different methods post-synthesis.
- This article aims to review the current research on using SBA-15 as a support for hydrodesulfurization (HDS) catalysts, focusing on its performance and modifications.
