“…The −Si–O–C and −Si–O–Si functionalities were confirmed by the appearance of the band in the range of 1130–1000 cm –1 . Appearance of the band in this range confirms the cross-linking of BC-PVA and Gelatin-PVA via the silanol functionality . The presence of the characteristic bands of the components in the spectra of bilayer hydrogel-nanofibrous scaffolds confirmed the successful fabrication of the target material.…”

Tissue engineering is currently one of the fastestgrowing areas of engineering, requiring the fabrication of advanced and multifunctional materials that can be used as scaffolds or dressings for tissue regeneration. In this work, we report a bilayer material prepared by electrospinning a hybrid material of poly(vinyl alcohol) (PVA) and bacterial cellulose (BC NFs) (top layer) over a highly interconnected porous 3D gelatin-PVA hydrogel obtained by a freeze-drying process (bottom layer). The techniques were combined to produce an advanced material with synergistic effects on the physical and biological properties of the two materials. The bilayer material was characterized using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and a water contact measurement system (WCMS). Studies on swelling, degradability, porosity, drug release, cellular and antibacterial activities were performed using standardized procedures and assays. FTIR confirmed cross-linking of both the top and bottom layers, and SEM showed porous structure for the bottom layer, random deposition of NFs on the surface, and aligned NFs in the cross section. The water contact angle (WCA) showed a hydrophilic surface for the bilayer material. Swelling analysis showed high swelling, and degradation analysis showed good stability. The bilayer material released Ag-sulfadiazine in a sustained and controlled manner and showed good antibacterial activities against severe disease-causing gram + ive and −ive (Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa) bacterial strains. In vitro biological studies were performed on fibroblasts (3T3) and human embryonic kidneys (HEK-293), which showed desirable cell viability, proliferation, and adhesion to the bilayer. Thus, the synergistic effect of NFs and the hydrogel resulted in a potential wound dressing material for wound healing and soft tissue engineering.

“…Recently, the researchers at CSIR-Central Building Research Institute conducted the research and development on cementitious composites employing a variety of mineral admixtures/supplementary cementitious materials [ [96] , [97] , [98] , [99] , [100] , [101] , [102] , [103] , [104] , [105] , [106] ]. Anurag et al [ 41 ], in their study on SCMs such as fly ash, silica fume, low-grade calcined limestone (CLS), low-grade uncalcined limestone (UCLS), and superplasticizer assessed various properties such as fineness, setting time, consistency, compressive strength, and flexural strength.…”
