Abstract:

ABSTRACT The butterfly pea flower (Clitoria ternatea) contains antioxidants that help combat premature skin aging. Peel-off masks are popular with consumers as topical formulations because they are unique and practical. An essential component of peel-off masks is the gelling agent Polyvinyl Alcohol (PVA), which acts as a film-forming agent. However, PVA at the wrong concentration can result poor mask physical properties. Combining PVA with other gelling agents can obtain peel-off masks with better physical properties. This study aims to identify the effect of PVA and iota carrageenan on the op

Abstract:

Abstract For the high content of carrageenan in some seaweed and the low cost and easy availability of semi refined carrageenan (SRC), SRC resin powder was selected as our research object. Due to its water solubility, a solution casting method was adopted to form film, hoping to prepare food packaging materials that partially replace petroleum based resin. The pure SRC resin casting film is very brittle and cannot be formed. Therefore, 40wt% glycerol was added to the formula to plasticize and improve the flexibility and demoulding ability of SRC. The plasticized SRC film still has limitations.

Abstract:

In this research, we prepared a polymer blend of polyvinylalcohol (PVA)/carrageenan/kaolinite by means of the solution cast approach. The composition of the blend was PVA in 1 gm by weight with 0.2 gm carrageenan as a plasticizer. The ratio of nanoclay varied between 1 and 5 wt%. Different properties were investigated in this study such as water vapor permeability, hardness, tear strength, color stability, thermal stability, and antibacterial activity. Water vapor permeability was decreased with increasing the ratio of nanoclay, while the values of hardness, tear strength, color stability, and

Abstract:

AbstractWe have investigated the potential of three dielectric materials to meet the future demands of green dielectrics: Polycaprolactone (PCL) thermoplastic, polyvinyl alcohol (PVA)‐carrageenan (CAR) crosslinked biopolymer, and boron nitride nanotubes (BNNTs) as a nano additive in PVA. Metal–insulator–metal (MIM) capacitors and organic thin film transistors (OTFT) were built with bilayer dielectric stacks of PVA‐CAR, PVA‐PCL, and PVA‐BNNT materials to examine their electrical properties. The PVA‐CAR layer uses a cyclic freeze thaw process to crosslink PVA and CAR for superior mechanical and

ABSTRACTThis study aimed to develop polyvinyl alcohol (PVA) and kappa‐carrageenan (κCA) biocomposite films using a Pickering emulsion technique for wound care applications. Juniper essential oil and modified sepiolite were incorporated to enhance functionality, with films prepared via solvent casting and characterized for structural, thermal, and mechanical properties. The PCOS‐2 film exhibited the highest mechanical performance, with Young's modulus of 6.25 ± 1.3 MPa, tensile strength of 5.65 ± 1.7 MPa, and elongation at break of 608.96% ± 72.8%.

Despite remarkable progress in medical sciences, modern man is still fighting the battle against cancer. In 2022, only in the USA, 640 000 deaths and 2 370 000 patients were reported because of cancer. Chemotherapy is the most widely used for cancer treatments. However, chemotherapeutics have severe physicochemical side effects. Therefore, we have prepared poly(amididoamine) dendrimeric carrageenan (CG), sodium alginate (SA) and poly(vinyl alcohol) (PVA) hydrogels by using solution casting methodology. The constituents of hydrogels were cross-linked by mutable quantity of 3-aminopropyl(diethox

Abstract:

Gentamicin production by immobilized cells of M. echinospora has been studied in repeated-batch processes using different immobilizing carriers such as calcium-alginate, carrageenan, agar, PVA, celite, polyurethane foam and activated carbon. With ca-alginate, gentamicin production was maximum (1096 mg/l) and the bead stability was good, whereby alginate was selected for further experimentation. The role of alginate concentration, CaCl2 concentration, bead diameter, curing time and bead inoculum quantity were studied. Better gentamicin outputs (1549 mg/l) were attained with alginate 4% (w/v), C

Abstract: Hydrogels are a three-dimensional (3D) network of hydrophilic polymers. The physical and chemical crosslinking of polymeric chains maintains the structure of the hydrogels even when they are swollen in water. They can be modified with thiol by thiol epoxy, thiol-ene, thiol-disulfide, or thiol-one reactions. Their application as a matrix for protein and drug delivery, cellular immobilization, regenerative medicine, and scaffolds for tissue engineering was initiated in the early 21st century.

The active packaging films were developed using kappa‐carrageenan and polyvinyl alcohol loaded with different concentrations (0.1%, 0.2%, and 0.3%) of clove essential oil. The impact of oil addition on the physiochemical properties of the films was evaluated using various techniques. GCMS analysis of the oil demonstrated the presence of three primary compounds in the clove oil, including eugenol (82.09%), caryophyllene (13.89%), and α‐humulene (2.26%), which contribute to the antioxidant and antimicrobial properties of the oil, thereby influencing the functional performance of the developed fi
