Special Issue Information
Dear Colleagues,
With the rapid increase in population and industrialization along with fast economic development and growing demands, the use of sustainable material has reached critical importance with respect to preserving the environment for future generations. In protecting the natural world, the needs regarding the production and application of sustainable materials to tackle environmental pollutants are being elevated. Some materials exhibit toxic properties, like carcinogenicity, with a high degree of potency. To eradicate environmental toxic pollutants, a reliable tool, such as sustainable materials, needs to be considered. The development of sustainable materials can create a significant change in the environment. These materials are safe and effective and could be managed in various ways to reduce wastefulness without changing their quality. Distinct properties, such as adsorption, redox potential, and photocatalytic activity, are available in advanced sustainable materials, which help to create a better environment. Manufacturing less toxic material in environmental application processes would ensure greater safety and the best future. These materials come from a sustainable system of production, use, and disposal and also offer innovation and learning opportunities for the conservation of resources for future generations. Many research works based on various science streams are required to extend the range of novel sustainable materials in the field of science and technology.
Sustainable materials are eco-friendly products originating from safe and natural resources. In pointing out the environmental issues, sustainable materials are considered as the first choice to resolve concerns. The current Special Issue will mainly focus on the application of sustainable materials in the field of sensing, monitoring, and remediation of toxic pollutants, including both organic and inorganic pollutants. In the search for more sustainable materials, this issue will cover the use of industrial materials, including chemicals and metals and, additionally, nonmetallic minerals, wood, fuels, and agricultural materials because these types of materials can create great environmental damage and also contribute wealth to our economy. Undoubtedly, the exploration of sustainable materials in environmental applications would pave the way for a cleaner environment.

Title: EFFECT OF ION Nd3+ ON CHARACTERIZATION, PHOTOCATALYTIC ACTIVITY OF ZnFe2O4 NANOPARTICLESof Sciences of Kazakhstan
Abstract: The present study aimed to optimize the production of Scenedesmus sp. biomass during the phy-coremediation process. The biomass productivity was optimized using face centred central com-posite design (FCCCD) in response surface methodology (RSM) as a function of two independ-ent variables included wet market wastewater concentrations (A) with a range of 10% to 75% and aeration rate (B) with a range of 0.02 to 4.0L/min. The results revealed that the highest biomass productivity (73 mg/L/d) and maximum growth rate (1.19 day-1) was achieved with the 64.26% of (A) and 3.08 L/min of (B). The GC-MS composition analysis of the biomass yield extract revealed that the major compounds are hexadecane (25%), glaucine (16.2%) and phytol (8.33%). The pres-ence of these compounds suggest that WMW has the potential to be used as a production medi-um for Scenedesmus sp. biomass which have several applications in the pharmaceutical and chemical industry.

Abstract: This study investigates the coagulative reduction of turbidity, COD, BOD, and colour from aquaculture wastewater (AW) using Garcinia kola coagulant (GKC). The coagulant was obtained from the seeds by complex salt extraction technique and was analysed for its spectral and morphological characteristics through the FTIR and SEM. The effects of GKC dosage (0.1-0.5g/L), pH (2-10), temperature (303-323K) and settling time (0-60min) on the pollutants reduction were examined. The process's coagulation-flocculation kinetics were also investigated in terms of total dissolved and suspended solids (TDSP). The seeds had 11.27% protein and 68.33% carbohydrate, showing usability in adsorption/charges neutralisation as a coagulant to reduce particles. Maximal turbidity reduction = 81.93%, COD = 75.03%, BOD = 72.84% and color = 56.69% at 0.3 gGKC/L, pH 2, 60 min and 303K is achieved. Von Smoluchowski's second-order perikinetics theory (with) was used to fit the results giving R2>0.9. At coagulation order (α) of 2, the reaction rate (Km) and coagulation-flocculation half-life (τ_(F1/2)) were evaluated as 0.0003 L/g.min and 25.3 min, respectively at the optimal conditions. Furthermore, the net cost of using GKC to handle 1 litre of AW (excluding electricity, material, and labor costs) was calculated to be 3.733€. In summary, these seeds can be used to pretreat AW.

Abstract: In recent years, the development of multi-phase eco-friendly lubricants improved overall tribological performance compared to petroleum-based oils. Vegetable oil, such as canola oil, being one of the commonly used oil, has become popular in the green world due to its non-toxicity and low cost. However, this bio-lubricant lacks tribological performance compared to petroleum-based oils. Solid lubricant additives have been added to the base oils to improve base oil's performance. However, the excessive use of solid lubricant additives can introduce undesirable effects. In this study, the tribological performance of canola oil was investigated by adding 0.5, 1.0, 1.5, and 2.0 wt.% graphene nanoplatelet (GNP) and 0.5, 1.0, and 1.5 wt.% hexagonal boron nitride (hBN) nano solid lubricant additives. The kinematic viscosities of these seven settings showed higher viscosity for GNP-incorporated oils compared to that with hBN. Experiments were conducted using pin-on-disk tests under boundary lubrication regime for the coefficient of friction (COF) and wear analyses. It was observed that for the GNP, 1.5 wt% provided the minimum COF (52 % less than base oil), whereas, for the hBN, 1.0 wt% provided the lowest (40% less than base oil) values. Based on these insights, three nano lubricant mixtures were formulated by incorporating GNP and hBN settings in different ratios. These mixtures provided an optimum positive synergy by reducing 61% friction and 80% wear compared to the base oil. The friction and wear reductions for combined solid lubricant additives in canola oil were significantly more compared to their individual settings. These improvements in the mixture were due to a composite film formed, which protected the interacting surfaces by mending and polishing mechanisms. Therefore, incorporating both these nanoparticles in canola oil could reduce friction and wear and thus help in better energy conservation and move towards a sustainable environment.
