“…A few factors affect the growth of bacteria, such as pH, temperature, nutrients, oxygen level, concentration, and species of bacteria [ 77 ]. Bacteria have been applied in many industries due to their potential and properties such as biological hydrogen, wastewater treatment, soil washing, biofilms, and biosensors [ 50 , 51 , 78 , 79 , 80 ]. Immobilization of bacteria on the surfaces depends on the characteristic of the material, the bond between surface and linker, physiological medium, and properties of bacteria [ 80 ].…”

Cellulose-based biodegradable hydrogel proves to be excellently suitable for the medical and water treatment industry based on the expressed properties such as its flexible structure and broad compatibility. Moreover, their potential to provide excellent waste management from the unutilized plant has triggered further study on the advanced biomaterial applications. To extend the use of cellulose-based hydrogel, additive manufacturing is a suitable technique for hydrogel fabrication in complex designs. Cellulose-based biomaterial ink used in 3D bioprinting can be further used for tissue engineering, drug delivery, protein study, microalgae, bacteria, and cell immobilization. This review includes a discussion on the techniques available for additive manufacturing, bio-based material, and the formation of a cellulose-based hydrogel.

Metal‐coordination mediated tough hydrogels have been considered as a promising materials for novel utilization in programmable actuation structures. However, the rate‐dependent mechanical behavior attributed to their intrinsic mechanical properties of mixed elasticity and viscosity, imposing a challenge for the realization of controllable deformations. In this work, the effect of stretch rate was incorporated into a variable fractional order model in order to describe and predict the rate‐dependent mechanical response of physically tough hydrogels. Firstly, we provide an iteration algorithm for model estimation and conduct simulations of the stress response under monotonic stretch to verify the applicability of proposed model. The performance of proposed model is compared with the existing model to validate its accuracy. Then, the present model is employed to describe the rate‐dependent stress response under cyclic loading. The change rule of related parameters with stretch rate is also unraveled by the present model, which is further utilized to test the model's predictive ability. Moreover, the physical meaning of variable order is qualitatively explored in conjunction with the evolution mechanism of dynamic bonds.

“…The dual hydrogen bond network in the ionic gel can not only enhance the repair ability of the polymer network but also improve the wear resistance and the bearing capacity of the lubricating film. These two excellent characteristics have promoted the further development of gel materials. , On the one hand, the self-healing characteristic of the ionic gel determines its service life and guarantees safety during application. − Compared with hydrogels, ionic gels have better stability because of the strong affinity of the ion pair . On the other hand, ionic gels have good effects in treating some extreme lubrication conditions because they meet the performance requirements of industrial lubricants, such as low pour point, high viscosity index, excellent oxidation stability, and low volatility. , However, ionic gels with two properties (lubrication and self-healing) have never been prepared using the same materials by changing the content of the solid matrix.…”

From one to more, the same raw materials giving rise to multifarious products is one of the goals of researchers to pursue industrial efficiency. Herein, we designed a formula (controlling the content of the matrix) to prepare two functional ionic gels, integrating the excellent lubrication, thermal conductivity, and self-healing ability to meet different industrial demands of the lubrication and biomedical fields. Deep eutectic solvents (DESs) of urea/choline chloride (UCC) and glycerol/ choline chloride (GCC) were locked in polyacrylamide (PAM) ionic gel formed by acrylamide (AM) and a photoinitiator by freeradical polymerization. The unique dual hydrogen bond network in the ionic gel causes the material to exhibit a low wear rate, which can effectively reduce the wear of metal contact. With the addition of PAM, the ionic gel has excellent mechanical strength and good recovery performance. Unexpectedly, this dense hydrogen bond network enhances thermal conductivity by optimizing phonon and electron transfer. The versatile ionic gel has a good application prospect as a substitute for industrial lubricants and medical device materials.
