There is great interest for NPs manufacturing by environmentally friendly and economic manner. The aqueous leaves extract of Thuja orientalis was used to synthesized silica nanoparticles (SiO2NPs) by using two green methods, the first one is the magnetic stirrer method and the second method by using the cold plasma. The XRD pattern for both samples annealed at Ta=600˚C for 1h, while they showed the characteristic of Bragg peaks for poly phases at (001), (010), (10-1), (1-10), (0-12) and (002) for SiO2 triclinic (anorthic). The average crystalline size was calculated by using Scherer’s formula, which was 11.1868 nm in magnetic stirrer method, while the cold plasma method showed amorphous structure. The morphology analysis using atomic force microscopy showed that the grain size was 33.94 and 18.37 nm for magnetic stirrer and cold plasma methods respectively. Fourier Transform Infrared Spectroscopy (FTIR) analysis indicates hydrophilic functional groups in the capping matrix, which can improve the stability of silica NPs. The biofilm inhibition of silica NPs were investigated for two genus of bacteria Staphylococcus aureus and Escherichia coli, the green silica NPs that synthesized by using cold plasma method showed the highest inhibition effect on S. aureus and E. coli respectively.

The research revolves around activating the role of modern technologies as a solution for developing products to achieve sustainability. Nanotechnology is considered one of the most important technologies that work on developing material properties and creating new materials. The problem addressed by the research is the failure to achieve sustainability in the design of some products due to the prevalence of many commonly used traditional products made from environmentally harmful materials and production methods that do not meet sustainability standards and represent a burden on the environment that is difficult to address. The research discussed the concept and importance of sustainability in product design, the historical development of material use in product design, and the development of new material properties in product design. It also discussed nanotechnology, nanomaterials, and their impact on developing product properties. Can new materials be used through nanotechnology to develop products and support them with properties that achieve sustainability? The research also aims to demonstrate how sustainability can be achieved in product design by transforming environmentally harmful traditional products into sustainable products by replacing harmful materials with new nanomaterials. It sheds light on the role of nanotechnology and the resulting nanomaterials in achieving sustainability in product design by developing their properties.

Two decades ago, nanotechnologies demonstrated various applications in different fields. As a result, an exposure to such particles has been risen dramatically within the last century due to anthropogenic sources of nanoparticles. The wide application of nanomaterials in industry, and products for consumers have raised concerns regarding the potential toxicity of nanoparticles to humans. For this Engineered Nano technology, materials have been proved to be with a great risk on human health and environment. For that reason, we now try to find solutions to manage this risks, for many scientific studies have proved it to be with a great dangerous impact. As an alternative solution, scientists work hard to extract natural nanomaterials from different sources of nature even from (agricultural crops - soil- sand ...etc.). The aim of the research is to focus on the potential uses of these extracted natural nanomaterials and study their physical and mechanical properties and applications in interior design and furniture fields, in a way to find Sustainable interior design using design principles such as functionality, and aesthetics and expand the focus to include environmental considerations by choosing materials with low environmental impacts. The research manipulated three components (Nano cellulose fibers sheets, Nano clays and shellac) together, and studied their structural properties, and the advantages of those green Nano materials for future trends and applications in the field of interior design. Two properties were examined on the prepared samples on this paper; contact angle and water absorption. For the purpose of mating between green Nano-materials and interior design for use in creating a comfortable environment for humans that can be environmentally friendly.

من الصعب تخيل مدي صغر تقنية النانو حيث أن النانومتر الواحد هو جزء من المليار من المتر، وعلم النانو يتضمن تكنولوجيا لها القدرة على رؤية الذرات والجزيئات الفردية والتحكم فيها، فكل شيء على وجه الأرض يتكون من الذرات، الطعام الذي نأكله والملابس التي نرتديها والمباني والمنازل التي نعيش فيها وأجسادنا، لكن شيئاً صغيراً مثل الذرة يستحيل رؤيته بالعين المجردة في الواقع، حتى أنه يستحيل رؤيته بواسطة المجاهر التي تستخدم عادةً في الفصول المدرسية، لذا فكان لزاماً اختراع مجاهر مخصصة لرؤية الأشياء بالمقياس النانوي، وقد حدث ذلك بالفعل في أوائل الثمانينات، وبمجرد حصول العلماء على الأدوات المناسبة كمجهر المسح النفقي(STM) ومجهر القوة الذرية(AFM) ولد عصر النانو تكنولوجي، وعلى الرغم من حداثة هذا العلم وتلك التكنولوجيا إلا أن المواد النانوية استخدمت لعدة قرون، ولكن الفنانون في تلك الأوقات لم يكونوا على دراية بماهية العملية التي قاموا بها لإنشاء هذه الأعمال الفنية الجميلة والتي أدت في الواقع إلى تغيرات في تكوين الخامات التي كانوا يستخدمونها، واليوم وجد العلماء والفنانون طرائق متنوعة لصنع الخامات بالمقياس النانوي للاستفادة من خصائصها المعززة كالصلابة الأكثر والوزن الأخف والتحكم في تأثير الضوء على الخامة وفي التفاعلات الكيميائية التي يمكن أن تحدث لتلك الخامات بسبب عوامل البيئة، وقد أحدث ذلك تطوراً كبيراً في فن النحت المعاصر. وفي الآونة الأخيرة تم تشكيل بعض المنحوتات على نطاق ضخم أثار إجاب المتلقي بأحجامها الهائلة، ويُنسب هذا الإعجاب الآثر للمهارات التقنية وتكنولوجيا النانو التي تمكنت أيضاً من إبداع أشكال لا يمكن تصديق صغر حجمها، حيث لا يزيد حجمها عن عين الإبرة وفي بعض المنحوتات قد تكون أصغر بكثير.

Constructed using the sol gel technique, the CdS nanoparticles contain cobalt. Scientists used X-ray diffraction (XRD) analysis to determine the properties of the particles they collected. The structural characterization results demonstrate the synthesis of impurity-free, Co-doped CdS nanoparticles in a single phase. We have shown and discussed the UV-VIS spectrophotometer-recorded optical absorption spectra of the doped sample in the 350-800 nm wavelength range. According to the Tauc relationship, the energy band gap is 2.46 eV. Potentially useful uses for co-doped CdS include photocatalysis, sensors, and solar cells.

The two types of nano carbons (NCs); carbon nanofibers (CNFs) and carbon nanotubes (CNTs) have been studied in numerous research works, which can extraordinarily enhance the mechanical properties of structural composites (concrete or soil-cement). Their amazing mechanical properties and tremendously high aspect ratios make NCs as the most valuable nanomaterials for nano-reinforcement. Yet, the dispersion of NCs is the major factor that strongly affects the properties of nan composites. A good deal of research has been carried out on chemical methods (chemical agent) to attain homogeneous dispersion of nano carbon in water. While if not precisely done, it can damage or shorten NCs and at the worst can dissolve them. This results in a negative effect on composites. Considering this, NCs can be physically dispersed in water and then mixed with composites. This paper presents a discussion on types of NCs and different dispersion techniques (chemical and physical), and research works in improve of soil properties use NCs.
