“…Also, drying at room temperature might induce the denaturation of trypsin, thereby losing its activity. Alteration in the structure of enzymes is generally related to the temperature (Hamza et al ., 2022). The molecular movement decreases at lower temperatures and increases with increasing temperatures (Kumar & Gupta, 1998).…”

Trypsin-loaded beads were produced using alginate and chitosan ionotropic gelation. Effects of drying methods (air-drying and freeze-drying) on characteristics and relative trypsin activity (RTA) of beads were studied. More homogeneous, spherical and smoother surface with larger size of beads and higher RTA were obtained by freeze-drying method than those of air-drying. Trehalose and/or glycerol at different concentrations (2.5 and 5%, w/v) were added in encapsulating materials and RTA of beads after freeze-drying and after simulated gastric digestion (SGD) was monitored. Freeze-dried trypsin beads with 5% glycerol (FDTB-G5) showed highest RTA after SGD. Moreover, highest degradation was attained when fish mince and sodium caseinate were hydrolysed with FDTB-G5 at a level of 100% of proteins tested in in vitro simulated gastrointestinal tract. Therefore, FDTB-G5 had better physical characteristics, which could withstand acidic condition and retain trypsin activity, thus favouring proteolysis when delivered to intestinal tract.

“…It has been observed that the morphology of NiFe 2 O 4 has changed by use of the changing preparation method. The main morphology of NiFe 2 O 4 obtained includes nanofibers (NiFO f ) by electrospinning, nanotubes (NiFO t ) by hydrothermal, NiFe 2 O 4 , nanorods (NiFO r ) by sol–gel, and nanospheres (NiFO s ) using the green process ( Hamza et al, 2022 ; Toghan et al, 2022 ). Figures 6A–D show the SEM images of NiFO f , NiFO t , NiFO r , and NiFO s , respectively.…”

A significant amount of energy can be produced using renewable energy sources; however, storing massive amounts of energy poses a substantial obstacle to energy production. Economic crisis has led to rapid developments in electrochemical (EC) energy storage devices (EESDs), especially rechargeable batteries, fuel cells, and supercapacitors (SCs), which are effective for energy storage systems. Researchers have lately suggested that among the various EESDs, the SC is an effective alternate for energy storage due to the presence of the following characteristics: SCs offer high-power density (PD), improvable energy density (ED), fast charging/discharging, and good cyclic stability. This review highlighted and analyzed the concepts of supercapacitors and types of supercapacitors on the basis of electrode materials, highlighted the several feasible synthesis processes for preparation of metal oxide (MO) nanoparticles, and discussed the morphological effects of MOs on the electrochemical performance of the devices. In this review, we primarily focus on pseudo-capacitors for SCs, which mainly contain MOs and their composite materials, and also highlight their future possibilities as a useful application of MO-based materials in supercapacitors. The novelty of MO’s electrode materials is primarily due to the presence of synergistic effects in the hybrid materials, rich redox activity, excellent conductivity, and chemical stability, making them excellent for SC applications.
