The paper aims to use Modern Dimensional Analysis () to study the polymers additive manufacturing optimization. The original part of the work is represented by the application of this nonconventional method in the field of polymers additive manufacturing. The laws of the model provide the complete sets of dimensionless variables, which cannot be offered by any of the classical methods (such as Geometric Analogy, Theory of Similarity, and Classical Dimensional Analysis). The validation of the method was performed experimentally. The original part of the work is represented by the application of this nonconventional method in the field of polymers additive manufacturing optimization. An application is presented and the necessary steps are analyzed one by one.

Polyhydroxyalkanoates (PHAs) represent a promising class of biodegradable polyesters synthesized by various microorganisms as energy storage compounds. Their versatility and environmental friendliness make them potential candidates for replacing conventional plastics across numerous applications. However, challenges such as limited mechanical properties, high production costs, and thermal instability have hindered their widespread adoption.

Oral drug delivery remains the preferred method of drug administration but due to poor solubility many active pharmaceutical ingredients (APIs) are ill suited to this. A number of methods to improve solubility of poorly soluble Biopharmaceutical Classification System (BCS) Class II drugs already exist but there is a lack of scalable, flexible methods. As such the current study applies the innovative technique of aerosol jet printing to increase the dissolution capabilities of a Class II drug in a manner which permits flexibility to allow dosage form tailoring.

The increasing CO concentration in the atmosphere has substantial impacts on the global temperature. For energy sustainability and minimization of the effects of global warming, an approach to understand CO capturing and a carbon neutral culture is extremely essential in the present circumstances. The CO emission from vehicles and industries can be minimized using energy cost-effective techniques and can be converted more selectively into reusable fuels via thermochemical, electrochemical, photochemical, photocatalytic, electrocatalytic, biological and inorganic carbonate-based approaches.

This study focused on developing biodegradable packaging films based on starch as an alternative to non-biodegradable such as petroleum-derived synthetic polymers. To improve its physicochemical properties, potato starch was chemically modified through phosphorylation. Starch phosphorylation was carried out using cyclic 1,3-propanediol phosphoryl chloride (CPPC), produced phosphorylated starch (PS), and analyzed using Fourier transform infrared (FT-IR), X-ray diffraction (XRD), Nuclear magnetic resonance (NMR), and Thermogravimetric analysis (TGA).

Solar-driven desalination technology is currently an important way to obtain freshwater resources. Significantly, porous materials are used as substrate materials of interface solar evaporator, and their specific impact of water transport property and thermal management during evaporation is worth exploring. In this paper, poly(vinyl alcohol) (PVA) sponges were prepared by a chemical foaming method, adjusted the PVA polymerization degree, and formaldehyde-hydroxyl ratio to regulate the pore size, and polypyrrole (PPy) was grown in situ on the surface skeleton of PVA sponge to construct a new interfacial solar evaporator (PPy/PVA) with different pore structures.
