“…PBS was prepares as described by our group elsewhere. [12][13][14][16][17][18]24] Equimolar amounts of 1,4butanediol (27 mL) and succinic acid (35.9 g) were used. The system was mounted using a heating plate under vacuum and nitrogen flow.…”

“…[9,10] Among the biodegradable polymers, poly (butylene succinate), PBS, can be obtained from petrochemical sources or by a wholly renewable route from chemical intermediates produced in the carbohydrates fermentation such as sucrose, glucose, maltose, and fructose. [11] PBS has excellent processability, biodegradability, low production value [12][13][14][15][16][17][18] and its microbiological degradation generates final products such as CO 2 and H 2 O. [19][20][21] Although PBS has good properties for application as a coating material in controlled release systems, its highly linear structure implies low melt strength, low viscosity, and low barrier property that limit some final applications of this biopolymer.…”

The risks of environmental damage are inherent in oil activities, being a constant concern to our modern society. Among the remediation strategies, the biological one is safer and more inexpensive compared to physic‐chemicals approaches. Bioremediation can be enhanced using biodegradable polymers as coating materials of the nutrient release systems. However, some of these polymers can be improved using electromagnetic radiation, able to modify their properties, such as, molar mass, changing the materials physicochemical behavior. Thus, immobilizing urea in poly (butylene succinate) (PBS) matrix, producing a petroleum bioremediation tool was the primary goal in the paper herein. The composites were obtained by melting at 110 °C with subsequent application of gamma (γ) radiation at doses of 15, 25, 50, and 75 kGy. The obtained results allowed to infer that the increase of the γ radiation doses improved the immobilization, thus reducing the immediate urea release. Besides that, the preliminary biodegradation results showed that the highest rates of hydrocarbon reduction at the end of the analysis period were reached using the material irradiated at 25 kGy. These results are encouraging and proved that irradiated PBS‐urea systems could be used as oil spill disasters tool.

“…57 For instance, several porous scaffolds composed of different materials were produced using salt leaching with adjustable porosity with different concentrations or sizes of salt particles. 97,98 Some novel leaching methods were explored to overcome the issues brought by the traditional leaching method. The porosity of the scaffold was able to achieve a high value when combined salt leaching and the gas foaming method.…”

“…The key disadvantage of leaching lies in its incapability to build controllable micro/macro geometries due to the randomness of salt distribution, and the formed shape highly depends on the dissolution behaviors of the sacrificial salts. [97][98][99][100] Additionally, residual solvents used to leach out particles might be toxic to cells. 105 In summary, the leaching method could produce a porous scaffold with controllable pore size, but is limited in the ability to control the exact size, shape and pore distributions.…”

Three‐dimensional (3D) printing technology has progressed exceedingly in the area of tissue engineering. Despite the tremendous potential of 3D printing, building scaffolds with complex 3D structure, especially with soft materials, still exist as a challenge due to the low mechanical strength of the materials. Recently, sacrificial materials have emerged as a possible solution to address this issue, as they could serve as temporary support or templates to fabricate scaffolds with intricate geometries, porous structures, and interconnected channels without deformation or collapse. Here, we outline the various types of scaffold biomaterials with sacrificial materials, their pros and cons, and mechanisms behind the sacrificial material removal, compare the manufacturing methods such as salt leaching, electrospinning, injection‐molding, bioprinting with advantages and disadvantages, and discuss how sacrificial materials could be applied in tissue‐specific applications to achieve desired structures. We finally conclude with future challenges and potential research directions.

“…Bio-PCMs are already studied to act improving the thermal properties of concrete, as found by Olawoore (8). It is biodegradable and its production is cheaper than its oil derivate counterparts, even though it is produced using renewable sources (10)(11)(12)(13)(14)(15)(16)(17). It can be produced by polycondensation of 1,4-butanediol and succinic acid/anhydride using many different catalysts (18).…”

the objective of this research is to test different variables combinations and show which Poly (cutylene succinate)based (PBS-based) material OBS material has the best properties to be added as a Bio-phage-change material in concrete matrices. In this experimental study, a novel PBS-based phase change material (PCM) was synthesized to be applied in concrete systems to increase thermal resistance. Box-Behnken design was followed to produce a total of 14 samples with different reaction times, catalyst concentrations, and glycerin concentrations (which acted as additives). All of the samples were able to decrease the regular melting point of PBS from 110ºC to around 68ºC, showing a significant improvement that allows the use of this material to improve the thermal properties of concrete systems.
