Extraction and characterization of cellulose from Anacardium occidentale shells: A sustainable approach to industrial waste management.

The utilization of industrial waste for eco-friendly product development plays a crucial role nowadays. Research on value-added products, such as cellulose derived from cashew nut shell waste (CNSW), was an inspiring aspect of the study. Numerous chemical procedures, such as the modified following acid hydrolysis approach, can be used to enhance the effectiveness of obtaining cellulose from waste.

Mechanical performance analysis of a 3D printing-based transtibial prosthetic socket against the gait cycle using the finite element method.

In order to restore near-normal gait patterns and increase patients' mobility post-amputation, prosthetic sockets are crucial. Currently, few 3D-printed prosthetic sockets are available, and little research has been conducted on their mechanical performance. Thus, the purpose of this study is to assess and characterize the performance of polyethylene terephthalate (PET), polycarbonate (PC), and polyamide 6/Nylon 6 (PA6) materials in prosthetic sockets fabricated 3D printing.

Impact of surface roughness and preheat temperature on fecrbmnsi coating properties prepared by the twin wire Arc spray method.

The purpose of this study is to evaluate the effects of substrate surface roughness (35 μm and 40 μm) and preheat temperature (50 °C, 100 °C, 150 °C) on the properties of the FeCrBMnSi coating layer applied to 304 stainless steels using the TWAS (Twin Wire Arc Spray) method. Surface preparation involved sandblasting and preheat treatment, followed by coating application with TWAS, and subsequent characterization using pull-off bonding, hardness, corrosion rate, Light Optical Microscope (LOM), and scanning electron microscopy (SEM) test. The current study's findings indicate that increasing preheat temperature and surface roughness consistently reduces the percentage of porosity, unmelted material, and coating layer thickness.

Value-added utilization of agricultural wastes in biocomposite production: Characteristics and applications.

Agro-waste-based biocomposites are reinforced with natural fibers derived from agricultural residues. These biocomposite materials have attracted a great deal of interest in recent years due to their environmentally friendly and sustainable nature as an alternative to conventional synthetic materials. Issues of environmental sustainability and the search for waste management solutions have driven research into the development of materials that minimize reliance on nonrenewable resources and have a low environmental impact.

Effect of alkaline treatment on the thermal and mechanical properties of sugar palm fibre reinforced thermoplastic polyurethane composites.

This study examines the impact of alkaline treatment on the mechanical, thermal, and morphological properties of sugar palm fiber (SPF)-reinforced thermoplastic polyurethane (TPU) composites. SPF fibers (250 μm) were treated with sodium hydroxide (NaOH) solutions of 0%, 2%, 4%, and 6% (w/w) for 90 min at room temperature. These fibers were then mixed with TPU in an extruder at 180-200 °C and molded into composite sheets using compression molding at 190 °C, 10 MPa pressure, and a 10-minute holding time.

Process parameters optimization of EDM for hybrid aluminum MMC using hybrid optimization technique.

This study explores how machining parameters affect Surface Roughness (SR), Tool Wear Rate (TWR), and Material Removal Rate (MRR) during Electrical Discharge Machining (EDM) of a hybrid aluminum metal matrix composite (AMMC). The composite includes 6 % Silicon carbide (SiC) and 6 % Boron carbide (BC) in an Aluminum 7075 (Al7075) matrix. A combined optimization approach was used to balance these factors, evaluating Pulse ON time, Current, Voltage, and Pulse OFF time.

Extraction and characterization of fiber from the flower stalk of Sansevieria cylindrica.

A number of natural fibers are being proposed for use in composite materials, especially those extracted from local plants, especially those able to grow spontaneously as they are cost-efficient and have unexplored potential. Sansevieria cylindrica, within the Asparagaceae (previously Agavacae) family, has recently been considered for application in polymer and rubber matrix composites. However, its characterization and even the sorting out of technical fiber from the stem remains scarce, with little available data, as is often the case when the fabrication of textiles is not involved.

Multiobjective Optimization of Fabrication Parameters of Jute Fiber/Polyester Composites with Egg Shell Powder and Nanoclay Filler.

In the present study, a model is presented to optimize the fabrication parameters of natural fiber reinforced polyester matrix composites with dual fillers. In particular, jute fiber mat was chosen as reinforcement and eggshell powder (ESP) and montmorillonite nanoclay (NC) were selected as fillers. The weight per square meter (GSM) of the fiber, the weight percentage of ESP and NC have been chosen as independent variables and the influence of these variables on tensile, flexural and impact strength of the composite has been inspected.
