Phase Change Materials (PCMs) for heat storage and energy saving has been extensively used in many fields for heating and cooling processes, including building, solar energy, textiles, agriculture, and electronics. PCMs have been getting incredible attention for being low-cost materials and have potential materials for thermal energy storage (TES) with long cycle life. Though, the disadvantages such as flow, result in encapsulation in three scales of Macro, Micro and Nano capsules. Encapsulating PCM reduces the disadvantages and improves the efficiency of PCMs. Different methods for producing PCMs in the scale of nano and core-shell materials, have been developed and the capsules size in relation to parameters such as pH, stirring rate, material selection and preparation method have been investigated. In recent years, this subject has been extensively studied, seeking to find more efficient and safer PCMs. In this context, nanoscale PCMs have been produced and applied to the most diverse products and their performance evaluated. They simply modified and optimized production processes. The novelty of this study lies in the fact that merely a few articles have reviewed nano-encapsulating of PCMs, focusing on new developments on PCM nano-capsules. Moreover, few articles have compared nano and microcapsules of PCMs so far. The analyzed papers suggest that the production methods influence the size of the obtained capsules. The purpose of this article is to make an updated review of the synthesis and application of nano-encapsulated PCMs.

In the 20th century, after the Russian revolution, artists were able to form a trend based on abstraction and geometry, which, by giving importance to the perception of the audience in various fields of art and architecture, has the purity of design in the use of visual arts elements.The current research, which was prepared by descriptive-analytical method and referring to reliable library, visual and electronic sources, with the aim of achieving minimalistic characteristics in fashion and clothing and its application in the design of Iranian women's nightwear inspired by the form and colors It is the traditional dress of Yazd province.The minimalist style in fashion design by avoiding individuality, regulating shapes, not using decoration, using new production methods in fibers, valuing fabric, key use of colors, curved and straight lines and subjects was able to make simple clothes. Market items for women with the most functionality, comfort and freedom in mass production. On the other hand, the use of this feature in the current research shows the adaptability and flexibility of the main design lines, cut and color of the traditional clothes of Yazd province with the minimalist style.

Gelatin is a natural polymer with strong polarity. It has molecular chains connected through strong hydrogen bonds, constituting a 3D macromolecular network. Because of its many merits, such as its biological origin, biodegradability, biocompatibility and commercial availability at relatively low cost, gelatin has been widely used in the pharmaceutical and medical fields. Electrospinning is a simple and versatile technique to generate nano to micrometer fibrous structures which are very similar to the natural febrile extracellular matrix (ECM). Morphology of electrospun fibers depends on solution, device and environmental parameters. Then in this research, we electrospinning 9 samples in different device conditions 3 different voltage (10,12,15 kV) and 3 different distance (distance between nozzle to collector:TCD) (10,15,20 CM). we surveyed FIBERS CHARACTERISTICS in device electrospinning parameter by SEM and FTIR tests that they observed nanofibers in the average standard deviation of them were 10-15% and their range varies also were between 79 to 139. and I also understood by increasing the voltage as well as the TCD, more fibers can be obtained with less beads and more uniformity

Silk fibroin (SF) is a natural fibrous protein that has been widely studied for application in the biomedical field as a matrix for tissue engineering. Pure fibroin was extracted from silk cocoon by degumming method using aqueous Na2CO3 solution followed by solubilizing in CaCl2-C2H5OH-H2O aqueous solution and frozen in liquid nitrogen, then lyophilized in freeze-dryer. SF fibers with diameters down to the nanometer range are formed by subjecting a fluid jet to a high electric field. The electrospinning of the SF sponge was performed with formic acid, as a spinning solvent, at 7% (w/w) fibroin concentration. In this regard, electrospinning parameters including voltage, flow rate, and distance were used as variable parameters, and the effect of changes in these parameters was investigated. The morphology of SF nanofibers was characterized by SEM. As the flow-rate increased, the available polymer volume was high, increasing the nanofiber diameter. Also, the lower the solution flow rate, the smaller the diameter of the resultant electrospun nanofibers and bead defects. With an increase in the distance between the capillary and the collector the nanofiber diameter initially decreased to a minimum and then increased.

Given the scarcity of quantitative and qualitative research in textile marketing management, the present study aimed to identify the significant global indicators in the last decade. To this end, an interpretative structural model was developed in the textile industry using a mixed-method study. In the first phase, more than 63 articles related to the subject of marketing in the field of the textile industry were selected and reviewed via conducting a systematic literature review. In the first phase, more than 63 articles related to the subject of marketing in the field of the textile industry were selected and reviewed via a systematic literature review. In the second phase, the Interpretive Structural Modeling (ISM) method was performed to identify the relationship among these indicators by evaluating them, obtaining interaction among trends and variables, and establishing the final model. The present model indicated that the factors affecting market orientation (i.e., the components of competitive performance variables, financial performance, organizational structure, dynamics among organizational units, comprehensive quality management, tendency to learn, tendency to entrepreneurship, strategic management of human resources, innovation ability, marketing ability, information and communication capability, competition structure, and business strategy) had high driving power and dependence. The results revealed that the performance of organizations in the market depends on the improvement of these components.

This library and field method study compared the motifs of contemporary Sirjan's Shirikipich carpet with that of the Qajar period and provided information on the motifs of the two periods. The purpose of studying these motifs was to know the extent of adherence of the current weavers to the motifs left from the past. The result of study revealed that the commercial process, the consumer's taste and the actuality of the sales market and of the old handlooms resulted in some changes in the patterns of carpets. The Shirikipich carpet design of Sirjan has undergone changes and new patterns have been added to it.
