Russia has a developed industry of building materials, which today implements an energy- and resource-saving model of its development. The implementation of the state policy of resource conservation is carried out in two main directions: the first direction is to save resources in the production of materials, the second is to increase the production of energy–efficient materials that allow saving energy carriers during their operation. Modern construc-tion in Russia is guided by European construction standards, which, in turn, provides for the construction of ener-gy-saving buildings with minimal energy consumption from external sources. This is ensured by the use of struc-tural and thermal insulation materials in the construction of external walls. In modern structural and thermal insu-lation materials for energy-saving construction, high requirements are imposed on their thermal properties, me-chanical strength and comfort level. From the point of view of simultaneous satisfaction of these requirements, ceramic materials have obvious advantages over other materials, in particular cellular concretes, which, with al-most the same level of thermal conductivity, are characterized by the least hygroscopicity and significantly greater strength. An objective prospect for the development of structural and thermal insulation ceramics is the production of hollow ceramic stones with increased thermal efficiency for their use in economical single-layer external wall structures without additional insulation. The products of individual Ukrainian manufacturers and even imported analogues of the most famous European manufacturer (Wiernerberger Company, Austria), when used in single-layer walls, do not provide regulatory requirements for the heat transfer resistance of masonry for the first temper-ature zone of Russia, which occupies the majority of the territory (60%). This requires the improvement of domes-tic products in the direction of improving their thermal characteristics (reducing thermal conductivity and increas-ing thermal resistance).

Quantum-dot cellular automata (QCA) is a technique that can substitute silicon transistors. Besides, the computational architecture and systems are focused on nanoscale QCA in response to industry demands for energy-efficient and high-performance computing systems. Because of the importance of adder/subtractor designs in logical circuits, a novel QCA-based adder/subtractor design is suggested in this study. A full adder is developed first, followed by a full subtractor. These QCA-based adder/subtractor designs are simple, ultra-efficient, constructive, and have easy input and output access.To create the required output, these circuits make use of quantum technology's intrinsic features. The QCADesigner program is used to assess the simulation findings of the recommended designs. Additionally, these designs are investigated in terms of complexity, clocking, cells, and latency. It shows that the recommended design is more efficient than standard designs regarding the area, cell count, and cost. These circuits are among the circuits in which easy access to inputs and outputs is provided, and their connection to other circuits makes them more practical. In addition to the above, the low number of cells, high speed, and easy implementation are among the innovations of the presented circuits. K E Y W O R D Sfull-adder, QCA, QCADesigner, quantum-dot cellular automata, subtractor INTRODUCTIONCMOS circuits may be made in a small amount of time, leading designers to look into it as a business strategy. 1 Documentation of leakage current and high-power usage in CMOS devices has surfaced in past years. As a result, the CMOS technological revolution must occur. Moore's law is followed by CMOS technology, which is based on today's conventional transistors. 2 Enhancing the transistors in a chip in CMOS technology is undesirable. However, since micro and nano-structures have gotten much attention recently, 3 a strategy at the nanoscale can demonstrate the ability to change Moore's law. That strategy is quantum-dot cellular automata (QCA) technology, which broke Moore's law by rapidly substituting innovative technology with CMOS. [4][5][6] In the QCA technology, several studies are conducted on the layout of different digital circuits like basic logic gates, 7 adders, 8,9 encoders, 10 subtractors, 11-13 multiplexers, 14-17 dividers, 18,19 and memory circuits. 20,21 Meanwhile, adders and subtractors hold a unique place in digital systems because they significantly influence their performance. 22,23 It is worth noting that developers strive to research a wide range of challenges, including complexity and limited occupancy space. However, owing to the novelty of this technology, there are still several significant hurdles that have yet to be overcome. 24

Recently, quantum dot-cellular automata (QCA) has fascinated much attention because of its potential less area consumption, low power usage, less intricacy, and low delay. The full-adder circuit is used in this technology for several procedures, like multiplication, subtraction, and division in the arithmetic logic unit. For this reason, the full-adder is generally investigated as a central unit in the development of QCA technology. The present investigation demonstrates a new efficient QCA-based full-adder layout utilizing the TIEO gate and new 3-input majority gate. In this design, the inputs get inside one side, and the outputs are derived from another circuit side. Other cells do not embrace the output and input signals, and they may simply be available, helping produce a more impressive circuit layout. Concretely speaking, in this design, the 0.02 μm 2 region and the latency of the 0.5 clock cycle have been implemented using only 18 cells. Utilizing the QCADesigner tool, the suggested design in the current investigation has been functionally approved. The simulation outcomes show that this layout conducts properly and works faster than the oldest designs.
