Abstract

Medical facilities are exposed to substantial health and safety hazards as a result of the existence of perilous substances such as germs, viruses, and mold. The integration of drug use courses in medical education is hindered by constraints such as time limitations, a scarcity of well-informed personnel, and insufficient institutional backing. In order to mitigate these dangers, a comprehensive assessment of the risks, effective instruction, and stringent procedures are required. Effective waste management systems and precise detection of influent are crucial. Activated carbon, a highly porous material, is extensively utilized as an adsorbent in several industrial applications. Bamboo charcoal, a desirable lignocellulosic substance, is employed in the manufacturing process of activated carbon. The objective of the study was to generate and examine activated carbons obtained from Gigantochloas Apus (GA) through the utilization of sodium hydroxide (NaOH) and sodium chloride (NaCl) activation methods. The study determined that was the most efficient activating agent for achieving ideal ash content characteristics, resulting in the lowest ash percentage of 6.21%. The acidity of medical liquid waste is increased and its adsorption duration is extended by activating GA with NaCl and NaOH.

Abstract

Coral reefs are vulnerable to several natural phenomena such as ocean warming, acidification, coral diseases, and plastic pollution. In order to tackle these problems, scientists are now working on the development of biocomposites utilizing biodegradable polymers such as polycaprolactone (PCL). Graphite can be used in conjunction with PCL to enhance its characteristics. The work is centered around conducting water absorption experiments on a composite material consisting of PCL and graphite. The investigation employs PCL granular and graphite powdered materials. The materials undergo heating, crushing, and weighing processes to ascertain weight ratios. Next, the mixture is shaped into specimens. The product's shape and distribution of chemical constituents are analyzed using water absorption, hydrophobicity, FTIR, and SEM testing. The findings indicate that the water absorption diminishes as the concentration of graphite powder increases. An alloy containing 10% graphite had the highest water absorption rate. The hydrophobicity test assesses the ability of a specimen's surface to repel water by introducing NaCl droplets and observing droplet production. The contact angle value exhibits a direct correlation with the increase in graphite content. The FTIR study indicates that there are no changes in the functional groups, resulting in a limited connection between the PCL matrix and the graphite filler. The temperature during the injection molding process affects the microstructure of the polymer. Lower temperatures lead to reduced crystallization, whereas higher temperatures result in denser molecular groupings. Graphite is a highly suitable choice for use as a filler in a PCL matrix because of its layered structure, large surface area, and excellent capacity to effectively fill voids within the matrix.

Abstract

The aim of this study is to examine the influence of immersing Petung Bamboo in a NaOH solution on the tensile strength (TS) of composites containing an epoxy matrix. Petung Bamboo Webbing was given 0%, 3%, 6% and 9%, soaking treatment. The Composite utilised in this investigation was fabricated by the Vacuum Assisted Resin Infusion technique. Tensile testing of composites is conducted according to the ASTM D638-1 standard. The findings indicated a positive correlation between the concentration of NaOH immersion and the adhesion between the woven surface of Petung Bamboo and the matrix. Consequently, the TS of the Composite was enhanced. However, increasing the concentrations beyond a certain point leads to more degradation of the lignin and cellulose in the fibers, resulting in a loss in the strength of the composite. The Petung Bamboo woven reinforced Composite achieved the highest TS of 136.06 MPa after being treated with a 6% NaOH immersion. This was followed by a 3% NaOH immersion treatment resulting in a TS of 106.04 MPa. Without any NaOH immersion treatment, the composite had a TS of 97.31 MPa. The lowest TS of the composite was observed after a 9% NaOH immersion treatment, measuring 90.79 MPa. The Petung Bamboo wicker-reinforced composite with NaOH immersion treatment showed higher fiber pullout and fiber-matrix debonding failures, while higher NaOH treatment concentration reduced these failures.

Abstract

Corrosion is a material degradation due to electrochemical reactions involving electrical current. Corrosion cannot be avoided but it can be managed. This work investigated the influence of holding time and temperature variation for the homogenization process of Zinc (Zn) alloy. This zinc alloy is used as a sacrificial anode to decrease the corrosion rate of API 5L X65 steel. The investigation was performed with 3 varied holding times of 2, 4 and 6 hours of homogenization process while the temperature was varied at 150, 250 and 350ºC. After that, a zinc alloy with a size of 40mm x 0.44 mm x 10 mm was connected to a cathode.  Together with steel, both metals formed galvanic cells in this study. The metal with lower electricity potential became the anode and corroded. On the other hand, metal with higher electrical potential became the cathode and did not corrode. The lowest corrosion rate was obtained for homogenization at 150ºC and 2 hours holding time. At this condition, the corrosion rate decreased by 38.36%. This occurred since higher temperatures and longer holding time of Zinc homogenization resulted in bigger and rougher grains.

Abstract

Of many compounds materials, metallic biomaterial is widely used in human medical devices. An implant material's corrosion resistance impacts its flexibility and longevity. This corrosion resistance is also an important consideration for biocompatibility. This biomaterial contains stainless steel whcih may corrode after being installed in the human body since  the passivity of stainless steel disappears when it is exposed to acids in the human body for a long duration. In addition, lacks of oxygen inhibits the formation of a new Cr2O3 layer for corrosion protection. Based on this phenomenon, an advance treatment is required to improve the resistance corrosion of implant. This study investigates the effect of the concentration and duration of chitosan on the thickness and corrosion resistance of biomaterials. The concentration of chitosan used was 0.08%, 0.16%, and 0.24% while the voltage used was constant at 10 V. The test results demonstrated the lowest corrosion rate occrured for 0.24 % chitosan concentration with 30 minutes coating duration. The lowest corrosion rate achieved was 0.014 mmpy and the maximum thickness was 75.4 μm. This study could be then used as a new solution to increase the safety of existing implants using biodegradable and non-toxic compounds. The next experiment should be implantation in real human body.

Abstract

This study aims to examine the phenomena that occur due to projectile penetration on fiber metal laminate. Ballistic testing was carried out experimentally according to National Institute of Justice standards (NIJ Standard 0101.06 level III-A) using a 9 mm full-metal jacket projectile with a normal angle of attack (90° to the target). The results showed that fiber metal laminate could withstand the projectile rate by penetrating the first layer (aluminum plate) and the second layer (aramid/epoxy), while the last layer was deformed to form a bulge. The pierced aluminum plate is characterized by petalling failure. Meanwhile, the aramid/epoxy was penetrated by the projectile with failure of the primary yarn to break the fiber.
