From a technical and economic point of view, our aim is to provide viable solutions for the replacement of fossil fuels which are currently used in internal combustion diesel engines. In this research, two new biofuels composed of second-generation vegetable oils (SVO),used oil sunflower (SO) or castor oil (CO), and the ABE blend (acetone/butanol/ethanol) were evaluated. ABE is an intermediate product from the fermentation of carbohydrates to obtain bio-butanol. Besides, the ABE blend exhibits suitable properties as biofuel, such asvery low kinematic viscosity, reasonable energy density, low autoignition temperature, and broad flammability limits. Diesel/ABE/SVO triple blends were prepared, characterized and then, tested on a diesel engine, evaluating power output, consumption, and exhaust emissions. The power output was slightly reduced due to the low heating values of ABE blend. Also, engine consumed more fuel with the triple blends than with diesel under low engine loads whereas, at medium and high loads, the fuel consumption was very similar to that of diesel. Regarding exhaust gas emissions, soot wasnotably reduced, and nitrogen oxides (NO) and carbon monoxide (CO) emissions were lower or comparable to that of diesel, while the CO emissions increased. The use of these biofuels allows the replacement of high percentagesof diesel without compromising engine power and achievinga significant reduction in pollution emissions. Furthermore, a notable improvement in cold flow properties of the fuel blends is obtained, in comparison with diesel.

Article Synopsis
- Researchers propose a new method for creating multiple shape memory polymers (SMPs) by mixing immiscible polymers under high pressure and shear, rather than traditional blending techniques.
- This approach allows for nanoscale homogeneity (40-95 nm) in the blends, improving both shape memory and mechanical performance.
- The study focused on a blend of polypropylene (PP) and polystyrene (PS), demonstrating that the processed blend achieves a strong triple shape memory effect with high shape fixation and recoverability, along with adjustable transition temperatures.

The significance of three-dimensional (3D) bioprinting in the domain of regenerative medicine and tissue engineering is readily apparent. To create a multi-functional bioinspired structure, 3D bioprinting requires high-performance bioinks. Bio-inks refer to substances that encapsulate viable cells and are employed in the printing procedure to construct 3D objects progressive through successive layers.

Intelligent hydrogels are promising in constructing scaffolds for the controlled delivery of drugs. Here, a dual thermo- and pH-responsive hydrogel called PCG [poly (N-isopropyl acrylamide-co-itaconic acid)/chitosan/glycerophosphate (PNI/CS/GP)] was established as the carrier of 5-fluorouracil (5-FU) for triple-negative breast cancer (TNBC) treatment. The PCG hydrogel was fabricated by blending synthesized [poly (N-isopropyl acrylamide-co-itaconic acid), pNIAAm-co-IA, PNI] with CS in the presence of GP as a crosslinking agent.

The main objective of this work was to use hydroxyl-functionalized graphene as a compatibilizer for an immiscible blend. A neat polyoxymethylene/styrene-butadiene-styrene binary blend was prepared at a constant ratio (80/20) and then was compounded with different loading amounts of hydroxyl-functionalized graphene (0.25, 0.

A covalent adaptable network (CAN) of semicrystalline polyolefin blends with triple-shape memory effects was fabricated by the reactive melt blending of maleated polypropylene (mPP) and maleated polyolefin elastomer (mPOE) (50 wt/50 wt) in the presence of a small amount of a tetrafunctional thiol (PETMP) and 1,5,7-triazabicyclo [4,4,0]dec-5-ene (TBD). The polymer blend formed a chemically crosslinked network via the reaction between the thiol group of PETMP and maleic anhydride of both polymers in the blend, which was confirmed by FTIR, the variation of torque during the melt mixing process, a solubility test, and DMA. DSC analysis revealed that the crosslinked polyolefin blends show two distinct crystalline melting transitions corresponding to each component polymer.
