Abstract: The aim of this study is the modification of the polycarbonate (PC) as synthetic polymer with the natural polymer - Spartium junceum L (SJL) fibers to obtain a new biodegradable polymer material. Spanish broom (Spartium junceum L) was chosen as reinforcement for PC composites because of her low cost, light weight, renewability, biodegradability and easily availability in nature.

Abstract: Titanium dioxide is a well-known substance for its photocatalytic properties. The aim of this article is to describe the influence of humidity and temperature on the self-cleaning properties of construction surfaces covered with a layer of titanium dioxide (further labeled as TiO2).

Abstract: Pharmaceuticals can be found in soil and aquatic environments as a result of human activity. They are released into the environment where they undergo soil sorption, photodegradation, and chemical transformation. [..] Read more

Abstract: The interaction between light and matter can be significantly enhanced through the excitation of surface plasmons and related nanospace-restricted focusing of light energy. The local enhancement of light energy is especially pronounced in the case of so-called plasmonic hotspots, which have found wide application in surface-enhanced Raman spectroscopy (SERS).

Abstract: The green alga Haematococcus pluvialis is highly regarded as a producer of astaxanthin. Due to its antioxidant properties, astaxanthin has become a popular nutritional ingredient. [..] Read more

Abstract: Arthrospira platensis (spirulina) is known for its high biological activity, including antioxidant, anti-inflammatory, and antiviral properties. In recent years, spirulina polysaccharides have been actively researched in fields such as tissue engineering, targeted drug delivery, and wound healing. [..] Read more

Abstract: Creatine is synthesized primarily in the liver and kidneys from amino acids and is phosphorylated to phosphocreatine, which serves as an energy source in muscle. Creatine is non-enzymatically degraded to creatinine at a constant rate and excreted in the urine. [..] Read more

Abstract: In this study, the reaction mechanisms of gold nanoparticles (AuNPs) synthesis using dialdehyde cellulose (DAC) and dialdehyde hyaluronate (DAH), and their covalent binding to chitosan nanofibers (CHITs), was investigated. The synthesis uses a redox reaction where dialdehyde polysaccharides are oxidized to dicarboxy polysaccharides and the gold salt precursor is reduced to elemental gold. [..] Read more

Abstract: The health of the vaginal microbiota is a crucial component of an intricate system. Vaginal drug delivery systems play an integral role in women's health by offering targeted and efficient treatment options for various gynaecological conditions, while aiming to minimally impact said bacterial population.

Abstract: Microplastics originating from the degradation of plastic waste are considered a global concern for the environment, with microplastic fibres from synthetic textiles being responsible for the majority of microplastic pollution. Over the past few decades, there has also been a notable increase in the production of synthetic polymeric materials in the form of nanofibers for various applications. [..] Read more

Abstract: Several experimental strategies have been formulated to develop theranostic liposomes by incorporating both drugs and various imaging contrast agents.in last decades. Liposome kinetics and cracking could be potentiated by external forces (ultrasound, electro-magnetic, laser induced). [..] Read more

Abstract: Zinc oxide (ZnO) is a low-cost and environmentally friendly material with unique optical properties and a variety of nano and microstructures imposing challenges for energy conversion, scintillators, photocatalytic wastewater treatment, electrochemical energy storage, or sensing applications. In this work, the nominally undoped and Al-doped nanocrystalline ZnO thin layers were pulsed laser deposited (PLD) on fused silica glass. [..] Read more

Abstract: Controlling nanoparticles (NPs) morphology in laser-mediated synthesis remains a significant challenge. This study introduces an innovative approach for synthesizing metal NPs using an Optical Vortex Beam (OVB) instead of the conventional Gaussian Beam (GB) in femtosecond laser ablation in liquids (fs-LAL). [..] Read more

Abstract: Calcination of phyllosilicate/organics nanocomposites in inert atmosphere leads to in situ formation of graphitic carbon layers on silicate phases. Electrically conductive material (ceramics) is thus obtained. [..] Read more

Abstract: The work focuses on the development of a linear electrode for the production of flat nanofibrous material by spinning a polymer solution using the AC electrospinning technique. This method is characterized by high productivity and the absence of an electrically active collector, which predisposes it to the production of advanced nanofibrous structures that will find application in medical and technical applications such as filtration or tissue engineering.Current spinning electrodes for AC electrospinning are characterized by a spinning surface with an overcritical electric field strength, from which polymer jets and subsequent nanofibers are created in all directions.
