In this study, the usefulness of estradiol-loaded (E2-loaded) PLGA-PEG-PLGA nanoparticles in the treatment of osteoporosis was investigated by comparison with E2-loaded PLGA nanoparticles. The cumulative E2 permeation of each nanoparticle through rat skin was quantified using a Franz cell. The results showed that PLGA-PEG-PLGA nanoparticles had significantly higher permeation than PLGA nanoparticles. Next, <em>in vivo</em> treatment experiments were conducted using an ovariectomized rat model of osteoporosis. Nanoparticles were administered once per week in combination with iontophoresis. At 6 weeks after the initiation of treatment, significant improvement in bone density was observed in the treated group compared with the untreated group. The improvement in bone density tended to be greater in the PLGA-PEG-PLGA nanoparticle group versus the PLGA nanoparticle group. This may be attributed to the higher hydrophilicity of the particle surface of PLGA-PEG-PLGA nanoparticles compared with PLGA nanoparticles and the improved skin permeability of the particles through the <em>trans</em>-adnexal pathway.</p></div>","PeriodicalId":101087,"journal":{"name":"Results in Materials","volume":"22 ","pages":"Article 100577"},"PeriodicalIF":0.0,"publicationDate":"2024-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590048X24000517/pdfft?md5=789512fa3486ad41674c3bed708338ea&pid=1-s2.0-S2590048X24000517-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140918975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These slab panels are popular in temporary constructions and beneficial in sustainability but have some financial limitations and local constraints. For a long time, the construction industry has used the arch action method, which restricts the stresses to the compression zone in concrete members and develops the required load-carrying capacity. For the same motives, industrial buildings have preferred semi-circular precast roofs, but the morphology was not suitable. For the proposed slab in this research, firstly, the typical industrial precast slab panel was doubled in width to minimize the time and efforts required for its casting, curing, and placement. Secondly, that doubled-in-width slab was provided with the arch action to confine the stresses to compression and benefit from the section entirely. Lastly, the top of the slab was kept flat to take advantage of the roof space. All these changes aimed for structural stability, reduced material's weight, improved load-carrying capacity, appropriate mobilization, and financial viability. A numerical approach and practical testing were adopted using the finite element modeling software, ABAQUS, to analyze load–deflection responses of both slabs through the concrete damage plasticity model. The proposed slab exhibited better performance as its capacity enhanced by about 1.5 times that of a typical slab. Although the volume of the material in the proposed slab increased slightly from 0.040 m³ to 0.045 m³, the reductions in joint filler materials, reinforcements, and efforts required for mixing and lifting machinery compensated for this increase significantly. Hence, the slab can be recommended for the industry to save the costs while taking heavier loads efficiently.</p></div>","PeriodicalId":101087,"journal":{"name":"Results in Materials","volume":"23 ","pages":"Article 100575"},"PeriodicalIF":0.0,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590048X24000499/pdfft?md5=72baf2a17b917195334b8195926222ba&pid=1-s2.0-S2590048X24000499-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141042675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For these reasons, in this investigation results of the characterization of physical and chemical behaviors of graphene-manganese oxide and copper and manganese oxide-copper systems are studied. The graphene was synthesized through the electrochemical exfoliation technique and deposited as a film on common glass and silicon substrates via the spray technique, and over this film, Mn₂O₃ films were deposited through spin coating. The Raman results showed the presence of peaks D and G, located at 1534 and 1597 cm⁻¹, respectively. XPS analysis demonstrated that the graphene is made up of three layers. TEM studies determined that the graphene is polycrystalline, and XRD established the manganese oxide coatings’ growth along the (222) and (440) planes of Mn₂O₃. The optical behavior indicated that the absorbance of the graphene-Mn₂O₃ system decreases the energy gap in 0.8 eV concerning Mn₂O₃ films. The voltage-current measurements suggest that the density current in the discharge process of the Mn₂O₃–Cu electrode system was improved approximately 3-fold with the graphene-Mn₂O₃–Cu electrode system. The obtained results conclude that the addition of graphene to manganese oxide coatings increases their electrochemical performance, so graphene-manganese oxide could be used in energy storage devices.</p></div>","PeriodicalId":101087,"journal":{"name":"Results in Materials","volume":"22 ","pages":"Article 100574"},"PeriodicalIF":0.0,"publicationDate":"2024-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590048X24000487/pdfft?md5=835332590bb2ff97db261a09d9695992&pid=1-s2.0-S2590048X24000487-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140645630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These cells use chemicals like photo-sensitizer(s), reductant(s), surfactant(s), alkali, solvent, and electrodes. Photo-decay and sacrifice of the chemical materials is imminent leading to the limited electrical output, efficiency and life of these cells. For realizing practical applications, the scalability of electrical output and stability of these devices is of utmost importance. Therefore, the long term photo-stability of Fast Green FCF dye-Fructose-Sodium lauryl sulphate (SLS)-NaOH electrolyte based cells has been studied in present work. The electrical output of the cell has been monitored over long period of time. Further, the photo-stability of electrolyte has been determined and analyzed spectroscopically. It has been observed that the Fast Green FCF dye-Fructose-SLS-NaOH photogalvanic cell device is capable of producing power even after decay of electrolyte. In early 24 h, about 90.54 % of dye degradation is observed. The cell is capable of giving current with even left out concentration ∼0.2 × 10⁻⁴ M (i.e., 9.46 % of initial concentration) of sensitizer. Further, the photo-degradation products (organic sulfonates) of FCF dye and SLS are also potential candidates for current generation.

The batch experiment was investigated at different CFPG dose (0.4–2 g), RhB concentration (5–30 mg/L), pH (2, 7 and 10) and contact time (30–300 min). The removal efficiency for the adsorption of RhB using CFPG was affected by dosage, concentration, and time. However, removal efficiency of 100 % was achieved at pH (2, 7 and 10) indicating that the adsorbent can be used in wide pH range owing to the zwitterionic nature of RhB. The findings demonstrated that while increasing the initial dye concentration resulted in a decrease in removal efficiency, increasing the CFPG dose and contact time led to an improvement in removal efficiency. Additionally, for specified values of examined parameters, such as CFPG dose of 2 g, initial RhB dye concentration of 5 mg/L, and contact time of 300 min, the maximum efficiency of 100 % was achieved for RhB dye removal.
