• A comparison of the drying processes used to prepare bacterial cellulose for wound dressing applications
  29/06/2024 by Thi Thanh Tam Phan
  Bacterial cellulose (BC) is a promising polymer due to its ability to manage wound exudation and create a moist environment conducive to healing, alongside its high tensile strength. The natural form of BC hydrogel prevents it from maintaining its shape; therefore, water needs to be removed. The preparation of BC for wound dressing use often […]
• Optimization of ultrasound-assisted extraction of crude polysaccharides and polyphenols from passion fruit peels
  29/06/2024 by Minh K.Q. Le
  Introduction: This study aimed to optimize the conditions of ultrasound-assisted extraction to simultaneously obtain the highest yields of polysaccharides and polyphenols from passion fruit (Passiflora edulis) peels. Methods: Box–Behnken design (BBD) and response surface methodology were employed for the optimization. The factors and their levels studied in BBD included a solvent-to-solid ratio (X1) of 30-70 […]
• Microbiological and Randomly Amplified Polymorphic DNA (RAPD) Marker Protocol for Silicone Condom Lubricant Isolates
  29/06/2024 by Oluwakemi Abike Thonda
  Condoms serve as a method of birth control. During sexual activity, silicon condom lubricant lowers friction and the chances of harm. Additionally, it increases the protection against STIs, including HIV, by decreasing the likelihood that they may break or fall off. The aim of this study was to perform microbiological and molecular assessments of silicon […]
• Design of a Multigate Field Effect Transistor-Based Adder for an Adaptive Filter in an Electroencephalogram Signal Analysis System
  29/06/2024 by Ravindrakumar Selvaraj
  Various noises and artifacts affect EEG (electroencephalogram) signals and should be removed for effective diagnosis and treatment. The adaptive filter is designed using adders, multipliers and delay elements. In this paper, the design of the adder is presented. The adders form the foundational block of all arithmetic and computational processes of biomedical systems. They form […]
• Low-cost synthesis of α-Fe2O3 nanorods for photocatalytic application
  29/06/2024 by Hoai Nhan Luong
  Introduction: α-Fe2O3 nanorods (α-Fe2O3 NRs), also known as hematite, possess a narrow band gap, high chemical stability, extensive surface area, controllable size, and outstanding photoelectric properties. These attributes make hematite a promising material for various applications, including gas sensors, optical sensors, and notably, photocatalysis. In previous studies, α-Fe2O3 nanorods were synthesized using various processes. However, […]
• The effect of temperature and reaction time on the physicochemical properties of oxidized bacterial cellulose membranes for hemostatic dressings
  29/06/2024 by Kieu Thi-Thuy Nguyen
  The development of an oxidized bacterial cellulose membrane (OBC) for hemostasis application is essential for preventing death from excessive bleeding. In previous research, OBC membranes were fabricated by using many different oxidation systems, notably the HNO3/H3PO4-NaNO2 system. In this study, the effects of oxidation conditions, such as temperature and reaction time, on the structure and […]

• Effect of reaction conditions on the etherification between glycerol and tert-butyl alcohol over beta zeolite
  29/06/2024 by Hong-Gam Thi Nguyen
  Introduction: Glycerol tert-butyl ethers (GTBEs) can be used as diesel additives due to their physico-chemical properties, such as flash point, viscosity, and cetane number. GTBEs were produced from the reaction between tert-butyl alcohol and glycerol using a stirred reactor at moderate temperatures. This study aims to discuss the effect of reaction conditions on the etherification […]
