Winged bean seeds are one of the constituents of nuts. Apart from their use as a culinary item, winged bean seeds can be utilized as a raw material to manufacture compostable coatings and films that help to extend the shelf life of food. Biodegradable coatings and films are intended to have physical and chemical qualities that enable them to perform these purposes. This study aimed to determine the chemical composition, morphology, thermal and infrared spectral of pretreated and raw winged bean flour. Proximate analysis revealed how pretreatment decreases winged bean flour's carbohydrate, protein, fat, and ash content. Throughout this period, the water content increased. Thermogravimetric analysis indicates two primary decomposition processes of pretreated winged bean flour showed prominent peaks at 271oC and 404.2oC with mass loss of 42.09 % and 32.95 %, respectively. Morphology analysis revealed that the average diameter of granules is the range value of 5-15 μm for pretreated flour. In accordance with the results of morphological analysis, the shape of the flour particles is uneven and tends to aggregate. On the other hand, infrared spectral exhibit polysaccharide in pretreated flour is expressed as 1,4 glycosidic linkages, amide I and amide II at bands 1161 cm-1, 1647 cm-1, and 1541 cm-1, respectively.","PeriodicalId":17134,"journal":{"name":"Journal of Sustainable Materials Processing and Management","volume":"372 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84928621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main components of these medicines must be able to endure longer and perform more effectively. Bone cement made of poly (methyl methacrylate) (PMMA), which is often used in damaged bone replacement surgery, is a vital biological material. As a result, the impact of additional nanoparticles such as zirconium dioxide (Zr02) and magnesium oxide (MgO) on polymer binary blends (Acrylic bone cement: 15% PMMA) for a bone scaffold was studied in this research. ZrO2 and MgO nanoparticles were introduced in various weights present to the polymer mix matrix 0, 0.5, 1, 1.5, 2). Hand lay-up molding using two different types of PMMA material was utilized to create the polymer. The reinforcement materials were mixed individually with a binary polymer blend material according to the reinforcement material selection ratio, and then heat-treated at 55°C for 3 hours to complete polymerization and remove any residual stress. Mechanical characteristics such as tensile strength and Young's modulus were evaluated for all of the prepared samples. The chemical bonding of nanoparticles and synthetic binary polymeric mix composites was evaluated using Fourier transform infrared spectroscopy (FTIR). The tensile strength and Young's modulus of a binary polymeric blend reinforced with (1.5wt% ZrO2, and 1wt% MgO) both dramatically increased. A scanning electron microscope (SEM) was used to examine the surface morphology of the fracture surface of tensile specimens. SEM images demonstrated that nanoparticles (ZrO2 and MgO) were distributed uniformly throughout the polymeric mix matrix.","PeriodicalId":17134,"journal":{"name":"Journal of Sustainable Materials Processing and Management","volume":"88 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75417139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Beds are regenerated and saturated simultaneously and are used cyclically. While one bed is undergoing adsorption, other is regenerated and vice versa. Regeneration of bed can be carried out by changing pressure or temperature. Former is called pressure swing adsorption (PSA) and later TSA. Heat is supplied for regeneration to desorb the impurities. Temperature required to regenerate the gas is high. Cycle time can be reduced and the process can be intensified by facilitating faster heat transfer in the bed. Normally the heat transfer coefficient of the adsorbent material is low which affects the cycle time. Better heat transfer can be obtained by increasing the heat transfer through packing by adding metal wires, strips or composite materials. Thus, metal fillings with good conductivity can be used in the bed. Technologies like TEPSA (Thermally Enhanced Pressure Swing Absorption) and TPSA (Temperature Pressure Swing Absorption) are developed for air pre-purification. TEPSA is a PSA process and TPSA is a TSA process. TEPSA is improved by addition of heat while in TPSA, adsorbate is removed by unheated regeneration gas. It is possible to make 20-60% power savings by moving to a TPSA cycle compared to TSA system. TPSA reduces not only cost of vessel but also pipe work involved in process. TPSA has a major advantage which is, without decreasing cycle time, thermal energy can be saved. This article explores various methods for intensification of Temperature swing adsorption. By combining advantages of pressure and temperature swing adsorption, solution to the problem of high energy demand and cycle time can be obtained. Proper selection of adsorbent material can be helpful in building economic process. Selection of adsorbent materials is based on various factors like cross-sectional area, strength, chemical inertness, etc. of the adsorbents. For TSA, thermal properties of adsorbent materials become significantly important while selecting the adsorbent.","PeriodicalId":17134,"journal":{"name":"Journal of Sustainable Materials Processing and Management","volume":"91 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83779049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Enhancement of solar energy absorption is the demand of time and CuO nanoparticles on account of their potential uses mainly in the field of solar energy applications. Cost effective sol-gel method is applied to synthesize CuO nanoparticles on solar evacuated glass tube. The synthesizing initiated from Cupric Acetate with the colloidal solution in water. A thin film has been prepared at room temperature nearly at 30 to 38 °C. The synthesized thin film had been annealed at 300 °C for one hour to give uniform grain structure and good surface morphological properties. For the structural study, the film was characterized by XRD-X-Ray diffraction, SEM-Scanning Electron Microscopy & TEM- Transmission Electron Microscopy. To exhibit the optical behavior of CuO nanoparticles on solar evacuated glass tube, UV-visible spectrum has been performed. By the calculations of an effective mass model, the size of particles determined as 2.26 nm, which supported and justified the TEM analysis. Coated CuO nanoparticles on borosilicate evacuated glass tube has been installed as a domestic solar water heater and working satisfactorily to generate hot water. For solar water heating system (domestic) application of nanotechnology is a novel concept. To develop durable nanocoating on 1800 mm long solar evacuated borosilicate glass tube itself it was a challenge.

Findings revealed that standard mixture and concrete with 25% pili nutshells replacement as fine aggregates has high workability. However, concrete with 25% pili nutshells replacement as coarse aggregates had medium workability. Furthermore, standard concrete is more economical compared to concrete with pili nutshells as coarse and fine aggregates.
