Qualitative research was undertaken with a literature study as the primary source of data collection by using accredited articles, journals and case studies to answer the research and sub-research questions.
The secondary method of data collection consisted of interviewing an expert in this field, as well as an accredited green star building professional in South Africa, knowledgeable in construction (names withheld).
The pie chart in figure 1 below indicates the prominence of each theme throughout the data.
Scope of Nanotechnology: The pie chart in figure 1 above indicates that the scope of the various uses of nanoparticles accounts for the most significant theme which emerged from the data.
Had Covid-19 not impacted the world the way it did, the data collection would have consisted of more in depth interviews with experts in the field.

The physical process included size reduction and calcination process which aimed to evaporate the water trapped in the zeolite pores.
The Fe-zeolite diffraction pattern was compared to the data from this software.
Diffraction pattern of Fe-Zeolite In addition to data interpretation using software, the diffraction pattern of Fe-zeolite was also compared with JCPDS data (Joint Committee on Powder Diffraction Standard).
In Table 3, Fe-zeolite was compared with existing JCPDS data from some references.
In the isomerization temperature of 40℃ and 60℃, the increase of acidity environment caused the reduction of fructose yield level.

The paper presents data about distribution of contact stresses on a rake surface and flank-land of a cutter in free orthogonal turning of a disk made from a titanium alloy (Ti-6Al-2Mo-2Cr).
Our experimental data allows calculating the components of cutting force and contact stresses on the rake and flank surfaces of cutting tools during titanium alloy (Ti-6Al-2Mo-2Cr) machining.
In our opinion it is connected with increase of temperature in the process of plastic deformation on an initial section of a flank surface chamfer and reduction of strength of workpiece material in the contact with a chamfer.
Our experimental data can be used to calculate the components of cutting force and contact stresses on a rake and a flank surfaces of cutting tools during machining of titanium alloy (Ti-6Al-2Mo-2Cr). 2.

This narrow groove preparation is also expected to have a contribution to the reduction of the necessary filler material.
Advantages of this variant of the GMAW process consist in productivity increase, by reduction of the bevel angle of the joint and also gains related to the mechanical/metallurgical properties, allied with lower susceptibility to defects, such as lack of fusion.
The chemical composition and the mechanical properties of plates of the steel S355J2+N are presented in the mentioned articles [1-7], as reference data for the development of the gas-metal-arc technology, with soun-arc and weaving facilities. 2.2.
This reduces labor costs - Three layers have been executed by the presented welding test piece, which also leads to reduction of material and labor costs, compared with similar welding operation, where five layers were used - High welding speed values in the range of 20 – 35 cm / min allow high productivity - The main original element of the presented technology consists in the combination of the spin-arc action on the wire-electrode, with the linear oscillation movement of the welding head, which both allow higher deposition rate.

The data were collected in a 10mHz100kHz
frequency range at temperatures from 450 to 750°C.
The oxygen reduction reaction occurring at the first PtAu electrode can be written, in analogy with a Pt/YSZ interface, as: ½ O2(gas) + 2e -(electrode) → O 2(electrolyte) where gas is the oxygen source, platinum electrode acts as electron reservoir, and YSZ is an ionic conductor.

The colloid and chemical bases on creation of highly effective multifunctional modifiers were developed on the basis of the experimental data in the field of chemical modifying of concrete compounds and concrete.
In general the stabilising effect of the surfactants is estimated by the degree of stability of the disperse system, modified by the data of surfactants, by the maximum surface, stabilized by surfactants in case of the given concentration and also by the limit concentration Ce.
Considering the available data on the structure, properties of plasticisers, their influence on colloid and chemical properties of mineral suspensions, the following requirements were offered to the oligomeric molecules in the study [24].
During the experiment the minimum quantity of the sulfuric acid, which was used at the stage of sulfonation, was determined by completeness of sulfonation and by absence of water insoluble impurities; the maximum quantity was determined by the beginning of reduction in MM intensity.
