Abstract A longstanding interest in bone tissue engineering is the development of new bio-scaffolds that can be manufactured on a large scale with high throughput at low cost.   Here, we report a low-cost and systematically optimized hydrothermal synthesis for producing Mo-doped potassium titanate nanofibers with high structural purity. This new nanosynthesis is based on bone tissue growth on an undoped titanate nanowires-entangled scaffold, as previously reported by our team. The morphological and structural characterization data suggest that the crystal structure of Mo-doped titanate nanofibers closely resembles that of the undoped ones. This resemblance is potentially valuable for assessing the role of Mo dopants in engineering bone tissue.

Abstract The present study deliberates the recovery of sodium fluoride (NaF)-natrite (Na 2 CO 3 )-sodium chloride (NaCl) ternary fluxing agent from hazardous aluminum dross waste using three types of heating methods, including direct heating on a hotplate, heating by a drying oven, and microwave heating. Deionized water was used as a green solvent for the recovery experiments. Investigating the effects of time and temperature on recovery percentage showed that a recovery percentage of around 96.5% can be achieved under time and temperature of 90 min and 95 ℃, respectively. The recovered fluxing agent salt was characterized by XRD, FTIR spectroscopy, FESEM, and energy dispersive X-ray spectroscopy (EDS) elemental analysis. Rietveld fitting analysis of phases detected in the XRD patterns showed that the recovered fluxing agent contained 74–81 wt.% NaF, 8–11 wt.% NaCl, and 11–14.7 wt.% Na 2 CO 3 . The FESEM micrographs revealed that the retrieved salts were in nano scale. The recovered fluxing agent showed different morphologies including needle-like, round shape, and a mixture of both, corresponding to microwave, drying oven, and hotplate heating methods, respectively. The nano-needles exhibited diameter of the tip and base in the range of 39–60 nm and 50–103 nm, respectively.

Abstract Green manufacturing is increasingly becoming popular especially in lubricant manufacturing as more environmentally friendly substitutes for mineral base oil and synthetic additives are being found amongst plant extracts and progress in methodologies for extraction and synthesis is being made. It has been observed that some of the important performance characteristics need enhancement of which nanoparticle addition has been noted as one of the effective solutions. However, the concentration of the addictive that would optimised the performance characteristics of interest remains a contending area of research. The research was out to find how the concentration of green synthesized aluminum oxide nanoparticles in nano-lubricants formed from selected vegetable oil influence the friction and wear. A bottom-up green synthesis approach was adopted to synthesize aluminum oxide (Al 2 O 3 ) from aluminum nitrate (Al(NO 3 ) 3 ) precursor in the presence of plant-based reducing agent— Ipomoea pes-caprae . The synthesized Al 2 O 3 nanoparticles were characterized using TEM and XRD and found to be mostly of spherical shape of sizes 44.73 nm. Al 2 O 3 nanoparticles at different concentrations—0.1 %wt, 0.3 %wt, 0.5 %wt, 0.7 %wt, and 1.0 %wt—were used as additives to castor, jatropha, and palm kernel oils to formulate nano lubricants and tested alternately on Ball-on-aluminum (SAE 332) and low-carbon steel Disc Tribometer. All the vegetable-based oil nano-lubricant showed a significant decrease in the Coefficient of Friction (CoF) and wear rate with Ball-on-(aluminum SAE 332) Disc Tribometer up to 0.5 %wt of the nanoparticle: the best performances ( e COF = 92.29; e WR = 79.53) coming from Al 2 O 3 -castor oil nano lubricant and Al 2 O 3 -palm kernel oil, afterwards the started to increase. However, the performance indices displayed irregular behaviour for both COF and Wear Rate (WR) when tested on a ball-on-low-carbon steel Disc Tribometer.

Abstract Paraffin wax is the most common phase change material (PCM) that has been broadly studied, leading to a reliable optimal for thermal energy storage in solar energy applications. The main advantages of paraffin are its high latent heat of fusion, low melting point that appropriate solar thermal energy application. In addition to its accessibility, ease of use and ability to be stored at room temperature for extended periods of time. Nevertheless, improving its low thermal conductivity is still a big noticeable challenge in recently published work. In this work, the effect of adding nano-Cu 2 O, nano-Al 2 O 3 and hybrid nano-Cu 2 O-Al 2 O 3 (1:1) at different mass concentrations (1, 3, and 5 wt.%) on the thermal characteristics of paraffin wax is investigated. The measured results showed that the peak values of thermal conductivity and diffusivity are achieved at wight concentration of 3% when nano-Cu 2 O, nano-Al 2 O 3 are added to paraffin wax with significant superiority for nano-Cu 2 O. While both of those thermal properties are negatively affected by increasing the concentration beyond this value. The results also showed the excellence of the proposed hybrid nanoparticles compared to nano-Cu 2 O, and nano-Al 2 O 3 as it achieves the highest values of thermal conductivity and diffusivity at weight concentration 5.0 wt.%.

Abstract The potential of nanotechnology to improve human health, optimize natural resource utilization, and reduce environmental pollution is remarkable. With the ever-growing advancement in dentistry, one of the breakthroughs is using nanotechnology. Nanotechnology in periodontics has touched every aspect of treatment modality, from non-surgical therapy to implant procedures, including regenerative procedures. Understanding of their mechanism plays a pivotal role in more efficient usage of nanotechnology, better treatment procedures, and eventually better outcomes. In this paper we review the application of nanotechnology in periodontal therapy. We performed the search for papers in Scopus using the key words and phrases as follows: “nanodentistry”; “dentistry and nanotechnology”; “dentistry and nanoparticles”; “dentistry and nanomedicine”; “dentistry and nanorobots”. There were found 530 papers in total. Some papers belonged to two and more categories. It is revealed that the number of papers versus year does not follow any specific pattern, but the cumulative amount of papers versus year is fitted with the exponential regression. There were also selected papers using certain inclusion/exclusion criteria. Only the selected papers were analyzed. Nanomedicine is subjected to intensive studies nowadays. There are some promising results that will likely be implemented into praxis soon in the fields of medical diagnostics and clinical therapeutics. The appearance of nanotechnology can have a considerable impact on treatment of periodontal diseases.

Abstract Graphene and derivatives have been frequently used to form advanced nanocomposites. A very significant utilization of polymer/graphene nanocomposite was found in the membrane sector. The up-to-date overview essentially highpoints the design, features, and advanced functions of graphene nanocomposite membranes towards gas separations. In this concern, pristine thin layer graphene as well as graphene nanocomposites with poly(dimethyl siloxane), polysulfone, poly(methyl methacrylate), polyimide, and other matrices have been perceived as gas separation membranes. In these membranes, the graphene dispersion and interaction with polymers through applying the appropriate processing techniques have led to optimum porosity, pore sizes, and pore distribution, i.e., suitable for selective separation of gaseous molecules. Consequently, the graphene derived nanocomposites brought about numerous revolutions in high performance gas separation membranes. The structural diversity of polymer/graphene nanocomposites has facilitated the membrane selective separation, permeation, and barrier processes especially in the separation of desired gaseous molecules, ions, and contaminants. Future research on the innovative nanoporous graphene-based membrane can overcome design/performance related challenging factors for technical utilizations.

Abstract Researchers from all over the world have been working tirelessly to combat the severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) COVID-19 pandemic since the World Health Organization (WHO) proclaimed it to be a pandemic in 2019. Expanding testing capacities, creating efficient medications, and creating safe and efficient COVID-19 (SARS CoV-2) vaccinations that provide the human body with long-lasting protection are a few tactics that need to be investigated. In clinical studies, drug delivery techniques including nanoparticles have been used since the early 1990s. Since then, as technology has advanced and the need for improved medication delivery has increased, wherein the field of nanomedicine has recently seen significant development. PNPs, or polymeric nanoparticles, are solid particles or particulate dispersions that range in size from 10 to 1000 nm and their ability to efficiently deliver therapeutics to specific targets makes them ideal drug carriers. This review article discusses the many polymeric nanoparticle (PNP) platforms developed to counteract the recent COVID-19 pandemic-related severe acute respiratory syndrome coronavirus (SARS-CoV-2). The primary subjects of this article are the size, shape, cytotoxicity, and release mechanism of each nanoparticle. The two kinds of preparation methods in the synthesis of polymeric nanoparticles have been discussed: the first group uses premade polymers, while the other group depends on the direct polymerization of monomers. A few of the PNPs that have been utilized to combat previous viral outbreaks against SARS-CoV-2 are also covered.

Research News: Decontamination of surface water from organic pollutants using graphene membranes

One of the most important problems nowadays is the contamination of the environment and more specifically of surface and underground waters by toxic substances, e.g., heavy metals and organic pollutants. Shortage of supplies of potable water is occurring in many areas worldwide, owing to the steady increase of the population, yielding to the harsh exploitation of water resources by human activities, which introduce many contaminants, including organic dyes, heavy metal ions, salts of light metals. In order to contrast what has by now already turned into one of the most severe concerns in the world’s community, it is necessary to carry out the decontamination of wastewater. Graphene oxide (GO) is a valid candidate for the absorption and removal of pollutants in water.

Graphene material is gradually being used in the fields of electronic technology and biomedicine due to its properties such as ductility, expandability and flexibility. The author gets efforts to explore some commercial graphene products such as graphene materials, aims to demonstrate a method to monitor the status of such a filter in real time during its operating phases: pollutant adsorption, saturation, and regeneration.

This study first showed that all types of graphene have excellent adsorption properties. This appears to be due to its large available surface area. This experiment provides a reference for exploring low-cost graphene materials and products preparation. With the continuous discovery of the properties of graphene and its composites and the continuous innovation of the preparation process, graphene will be applied to various devices in daily life and become an indispensable part of our lives.
