The method relies on the slow hydrolysis of acetyl groups directly in an acetone/aqueous ammonia solution. The gradual pace of the process creates conditions favourable for reconstructing of inter- and intramolecular hydrogen bonding networks between the newly formed hydroxyl groups in the cellulose, resulting in a rigid three-dimensional structure. The hydrogels demonstrated excellent mechanical properties, with a compressive (Young's) modulus of up to 43 MPa and an elastic modulus of up to 0.23 MPa. X-ray analysis indicated that the cellulose hydrogels are semi-crystalline, with a crystallinity index of 43–45% and an average crystallite size of 4.3–4.5 nm. Wide-angle X-ray diffraction, along with FT-IR and Raman spectroscopy, confirmed that the gels belong to the cellulose II structural modification. The porous structure of the hydrogels was characterized using inverse size exclusion chromatography, revealing exclusion limits for linear polymers of up to 4 × 10<small>⁶</small> Da. Thanks to their enhanced mechanical properties and high porosity, crushed hydrogels show potential applications in column technologies for protein chromatography and heterogeneous biocatalysis processes with immobilized enzymes. In film form, the gels' elasticity makes them promising candidates for biomedical applications, such as wound dressings or artificial skin.

We were able to stabilise the PVDF's β-phase without the need for external electrical polling by employing this filler. Negative surface charge of the fly ash facilitates the β-phase stabilization in PVDF by means of electrostatic contact. A flexible fly ash/PVDF composite using 15 wt% calcined fly ash was prepared using a low-cost solution casting technique. The fly ash can successfully stabilize the β-phase of the PVDF polymer up to ∼90%. The CFA/PVDF composite was subsequently moulded and positioned between the copper electrodes.

Transdermal nano collagen, a type of short synthetic collagen, has attracted growing attention for its ability to mimic the structure and function of natural collagen, while its applications in skin repair dressings remain unexplored. Herein, we have for the first time developed a novel type of transdermal nano collagen dressing (TNCD) for accelerated healing of photodamaged skin. The TNCD was formulated using the transdermal nano collagen, GRR2, as the efficacious ingredient, exhibiting highly stable physical and chemical properties. DermaLab Combo evaluations revealed that, compared to commercial collagen dressings, the TNCD significantly accelerated the recovery of skin density, erythema index, and transepidermal water loss (TEWL) in damaged skin to levels comparable with that of healthy skin. Histological analyses further confirmed that the TNCD effectively repaired photodamaged skin by promoting the regeneration of collagen fibers.
