پیشرفتهای تکنولوژی عصر حاضر در واقع، بستگی به دستاوردهایی دارد که در زمینه مواد حاصل شده است. در این میان، مواد کامپوزیتی معرف قدمهای بزرگی است که در راه تکامل مواد مهندسی برداشته شده است. با ترکیب کردن فیزیکی دو یا چند ماده، علاوه بر اینکه موادی سبکتر و محکمتر از مصالح سنتی، از قبیل فلزات، سرامیکها، چوبها و پلیمرهای معمولی، میتوان به دست آورد، بلکه میتوان برای هر کاربرد مشخص، خواص مورد نظری را...

To provide an eco-friendly disposal way of increasingly accumulated waste tyres and reduce the environmental impact caused by production industrial fibres, this study explores feasibility using recycled tyre materials as substitutes for natural fine aggregates manufactured fibres in cementitious mortar. The effects crumb rubber (CR) replacement ratio (5%–15% volume aggregates), steel (RTS) fibr...
Microplastics uptake in wild Asian green mussels sampled from Pasir Putih estuary in Johor, Malaysia
Abstract The high concentrations of plastic and debris in the environment continue to rise each year as most plastics undergo minimal biological degradation. As are exposed sunlight, atmosphere, water, these polymers break into smaller pieces become individual polymer molecules. In this study, presence microplastics (MPs) mussels was investigated. Wild Asian green ( Perna viridis ) samples were...
AIM The aim of this in vitro study was to compare the flexural strength, the flexural modulus and compressive strength of the acrylic polymer reinforced with glass, carbon, polyethylene and Kevlar fibres with that of plain unfilled resin. MATERIALS AND METHODS A total of 50 specimens were prepared and divided into 10 specimens each under 5 groups namely group 1- control group without any fibr...
BACKGROUND Many of today's treatments associated with 'thinning hair', such as female pattern hair loss and telogen effluvium, are focused on two of the key aspects of the condition. Over-the-counter or prescription medications are often focused on improving scalp hair density while high-quality cosmetic products work to prevent further hair damage and minimize mid-fibre breakage. Fibre diamete...
In this paper, different polymer optical fibres for applications in force sensing systems in textile fabrics are reported. The proposed method is based on the deflection of the light in fibre waveguides. Applying a force on the fibre changes the geometry and affects the wave guiding properties and hence induces light loss in the optical fibre. Fibres out of three different elastic and transpare...
In today's fast-developing world, the use of composite materials is closely related to environmental pollution, renewable and biodegradable resources. A researcher looking for environmentally friendly materials. Natural synthetic fibres come in a wide range shapes sizes. include jute, straw wheat, rice husk banana fibre, pineapple leaf cotton, Sisal, Coir, Oats, Bagasse. Every year, 13.5 tonnes...
Extracellular vesicles (EVs) are cell-derived bodies proven to have a wide range of therapeutic applications. To date, EVs almost always been administered by direct injection, which is very likely hinder their efficacy because rapid clearance from the injection site. Here we show that can be successfully processed into polymer-based fibres electrospinning, with no loss structure or function.
