abstract = {The development of aqueous vitamin D3 supplements remains challenging because the molecule is poorly soluble, chemically fragile, and prone to loss of potency during storage. In this work, we adopted a Quality-by-Design (QbD) strategy to construct a nanoliposomal structure able to protect and deliver vitamin D3 while maintaining technological simplicity and high tolerability. As a first step, drug-free nanoliposomes were produced using a coaxial-jet mixer and systematically investigated through a Box–Behnken Design. This approach allowed us to identify the critical relationships between phosphatidylcholine concentration, solvent/antisolvent flow rates, and the resulting nanoliposomal architecture, thereby defining a robust design space for nano-vesicle formation. Vitamin D3 was then introduced into the optimized system to verify process transferability. Encapsulation proved efficient and compatible with the micromixing-driven assembly of nanoliposomes, and the formulation was subsequently subjected to accelerated and real-time stability studies. These experiments revealed a clear hierarchy of stabilizing effects, highlighting the combined protective role of the liposomal bilayer and a carefully balanced antioxidant environment. Building on these findings, the research formulation was further refined into a commercially viable product, described in a dedicated patent, and benchmarked against leading marketed references. The final dispersion exhibited high structural uniformity, stable vitamin retention and manufacturing features consistent with large-scale implementation. Overall, this work demonstrates how a QbD-guided pathway — from mechanistic process mapping to stability-driven optimization and product translation — can yield a high-quality nanoliposomal vitamin D3 with clear technological and practical advantages.},

abstract = {This study investigated the use of PhenylGlyoxAldehyde (PGA)-functionalized polymer beads as urea sorbents for closed-loop hemodialysis. The impact of initial urea concentration and volumetric flow rate was assessed through dynamic in vitro experiments using packed columns (8 g PGA beads; 12–40 mL/min; 15–30 mM urea). The adsorption kinetics were modeled using a pseudo-second-order equation combined with a Langmuir isotherm (binding capacity up to 1.85 mmol/g at 37 °C). Within the low-Reynolds-number regime explored, the pseudo-kinetic constant increased linearly with average section velocity (3.86–5.51 × 10−6 L mol⁻¹·s⁻¹ for 2.4–8 cm/min), in line with the expected increased mass transport. The model accurately predicted urea adsorption in single and dual-column (series and parallel) configurations, and it was extended to simulate in vivo closed-loop dialysis. To remove ∼330 mmol of urea — equivalent to daily production — in a 2.5 h session, a total of 1 kg of dry PGA (3.5 kg of wet PGA) would be required, making the system suitable for portable hemodialysis. When dialysis is extended to 8 h (e.g., nocturnal home therapy), the sorbent requirement reduces to 0.6 kg of dry PGA (2.1 kg of wet PGA). While not wearable, this configuration may enable the development of compact bedside dialysis systems. The validated model offers a predictive framework for optimizing system design and scaling to other sorbates and clinical scenarios.},

abstract = {This study addresses the need for scalable and predictive strategies linking mixing conditions to nanocarrier properties by developing and analyzing a coaxial jet antisolvent process for the continuous production of pharmaceutical nanocarriers. Methods: A single experimental platform was used to generate both curcumin-based nanoparticles and nanoliposomes, enabling direct comparison of how mixing regime and formulation variables influence product characteristics. Results: Fluid-dynamic behavior was first characterized using tracer and micromixing experiments, revealing a strong dependence of mixing time on flow conditions, with characteristic mixing times decreasing from >1000 ms under laminar conditions to approximately 10–30 ms in turbulent regimes. Nanoparticles and liposomes obtained under optimized conditions exhibited mean sizes in the range of 120–250 nm, with polydispersity indices typically below 0.2 under optimized turbulent conditions. To rationalize these observations, a computational framework was implemented, combining Reynolds-averaged computational fluid dynamics with a population balance formulation solved by the method of moments. The model provided spatially resolved insight into solvent exchange, supersaturation development, and nucleation–growth dynamics, showing good agreement with experimental trends and capturing the effect of mixing conditions on particle size across different regimes. Conclusions: Although simplified, the modeling approach establishes the basis for future extensions toward full population-balance distribution simulations capable of predicting complete particle size distributions, highlighting the ability of the coaxial jet mixer to control supersaturation and particle formation through tunable hydrodynamic conditions. This capability makes the system particularly attractive compared to conventional batch or less controllable mixing technologies, enabling a more rational and scalable design of pharmaceutical nanocarriers, with good encapsulation performance as discussed in the main text.},

abstract = {Nerolidol (NER) is a sesquiterpene alcohol with recognized antimicrobial potential, whose applications as a pure substance are limited by hydrophobicity, instability, and cytotoxicity. Invasomes, i.e., liposomes with terpene ingredients, offer a strategy to improve their delivery; however, the NER loading limits compatible with vesicle integrity are still unclear. Here, Nerolidol-loaded invasomes were produced using a controlled simil-microfluidic coaxial injection process. Methods and Results: As a preliminary step, unloaded liposomes were fabricated to consolidate operating conditions and ensure their reproducible colloidal properties. Thereafter, formulations with progressively decreasing nominal NER loads were investigated to evaluate vesicle size, polydispersity, ζ-potential, encapsulation efficiency, effective loading, and stability. High nominal loads promoted turbidity, size increase (by agglomeration coalescence phenomena), and structural instability, whereas formulations containing approximately 1–2% NER achieved nearly complete encapsulation, Z-average ≈ 300 nm, |ζ| > 30 mV, and satisfactory physical stability. Antimicrobial and cytotoxic profiles of representative formulations, previously evaluated in an independent study are here reported only to contextualize the practical relevance of the optimized systems, while the present work primarily focuses on process–formulation aspects and loading/stability limitations. Conclusions: Overall, the present work identifies a realistic loading window for Nerolidol invasomes and highlights the suitability of the simil-microfluidic approach to obtain scalable, well-controlled formulations, providing a rational basis for their future biological assessment. Nerolidol invasome systems indeed can be considered a promising, versatile platform for antimicrobial applications, including prospective use in animal feed.},

abstract = {The accumulation of waste tires and their environmental impact is a serious global issue. Incorporating Crumb Rubber (CR) into asphalt mixtures allows this waste to be recycled while improving pavement performance, but it also increases production temperatures, energy use, and emissions. Warm Mix Asphalt (WMA) additives can mitigate this drawback, enabling more sustainable mixtures. This study presents laboratory investigation of the rheological properties and mechanical performance of CR–modified asphalt binder and mixtures obtained by wet process and containing Sasobit as a WMA additive. The bitumen investigation employed penetration, softening point, viscosity, and dynamic shear rheometer tests. Results showed that CR increased binder stiffness, as evidenced by reduced penetration and higher softening point, while Sasobit further contributed to lowering penetration at low temperatures but also reduced viscosity at high temperatures, thus improving workability. The formulation with 15 % CR and 3 % Sasobit (15 %CR–3 %S) emerged as the optimal compromise, achieving a high-temperature Performance Grade (PG 82) without excessive stiffness. The dynamic (complex) modulus and fatigue resistance at different temperatures and load frequencies of the 15 %CR CR–3 %S modified asphalt mixture, intended for use as the wearing course of road pavements, were evaluated through 4-point bending tests. Moreover, dynamic creep tests were conducted to assess its rutting resistance. Compared with the unmodified asphalt mixture, the modified one generally exhibited a higher complex modulus, improved fatigue resistance, and enhanced rutting resistance. These results indicate that combining CR with Sasobit enhances binder rheology and asphalt mixture performance while supporting lower-temperature production, contributing to the development of more sustainable asphalt pavements.},

abstract = {The application of microwave-assisted drying is a promising technique due to the features of process sustainability that are usable for responsible productions. It is largely applied for the stabilization of food products, especially in the agro-food sector. In this study, the weed Portulaca oleracea L. (purslane), with its richness in antioxidant components in addition to its recognized pharmacological properties, has been considered due to its potential to be a natural, well-accepted future food. Attention was focused on the role of the heat and mass transfer rates involved in the drying processes on the nutritional profile of the dried products. For this purpose, different drying protocols (convective, microwave irradiation, microwave-vacuum irradiation) were applied to different parts of purslane herb (apical, twigs, entire structures) and chemical characterizations were performed by a GC/MS analysis of the extracts of the dried products. The results show that microwave treatments can assure a better preservation of fatty acids such as SFAs, MUFAs, and PUFAs (which constitute over 90% of the total components in the apical part, 65% in twigs, and 85% in microwave-vacuum-dried entire purslane samples) and phytosterols (their highest preservation was found in microwave-dried twigs) compared with convective treatments. The chemical composition variability as well as treatment times depend on the drying rates (in microwave treatments, the times are on a minute scale and the rates are up to three orders of magnitude greater than convective ones), which in turn depend on the heating transport phenomena. This variability can lead towards products that are diversified by properties that transform a weed into a valorized food source.},

abstract = {Liposomes, due to their mimetic cellular composition, are gaining great attention as release systems for lipophilic and hydrophilic molecules. However, liposomes can present a high tendency to degrade and aggregate into biological fluids and under storage conditions. To overcome these limitations, in this work, a stabilizing strategy consisting in liposomes incorporation into polymeric granules was studied. Wet granulation was adopted to produce granules of hydroxypropyl methylcellulose (HPMC) and liposomal suspensions were used as the binder phase. In particular, in this study, three different percentages of liposome load in HPMC granules were investigated (1%, 5% and 10% w/w) focusing the attention on several relevant technological characteristics of the achieved solid particulates: size, flow index, mechanical strength (granules without liposomal inclusions were used as a control). Morphological observations (by TEM) confirmed the presence of intact liposomes in dry HPMC granules; moreover, it was found that the binder phase with the lower liposome concentrations (1%, 5%) did not significantly affect size, flowability and hardness of the lipid-polymer granules. Instead, the granules containing the highest percentage of liposomes (10% w/w) have larger dimensions, harder structure and reduced flowability. Therefore, the followed process strategy, under liposomal concentration restrictions, allowed to obtain both the liposomes stabilization, a not trivial technological issue, and the production of particulates with good solid state properties, useful as a versatile dosage form (lipid carriers in polymer carriers).},

Then, the current status of siRNA-lipid delivery systems in clinical trials is addressed, offering an updated overview on the clinical goals and the next challenges of this new class of therapeutics which will soon replace traditional drugs},

abstract = {Micronutrients administration by fortification of staple and complementary foods is a followed strategy to fight malnutrition and micronutrient deficiencies and related pathologies. There is a great industrial interest in preparation of formulations for joint administration of vitamin D3 and vitamin K2 for providing bone support, promoting heart health and helping boost immunity. To respond to this topic, in this work, uncoated nanoliposomes loaded with vitamin D3 and K2 were successfully prepared, by using a novel, high-yield and semi continuous technique based on simil-microfluidic principles. By the same technique, to promote and to enhance mucoadhesiveness and stability of the produced liposomal structures, chitosan was tested as covering material. By this way polymer–lipid hybrid nanoparticles, encapsulating vitamin D3 and vitamin K2, with improved features in terms of stability, loading and mucoadhesiveness were produced for potential nutraceutical and pharmaceutical applications.},

abstract = {Liposomes constitute a class of prominent drug delivery systems due their cell-mimetic behaviour. Despite

their high biocompatibility, biodegradability and low intrinsic toxicity, their poor stability in biological fluids

as well as in stock conditions (high tendency to degrade or aggregate) have led to new approaches for

liposome stabilization (e.g., surface covering with polymers). Here, liposomes were enwrapped by the

natural biocompatible polymer chitosan to achieve stable shell–core nanostructures. Covered

nanoliposomes were produced using an innovative continuous method based on microfluidic principles.

The produced hybrid polymeric-lipid nanoparticles were characterized in terms of structural properties,

size and stability. Moreover, phenomenological aspects in formation of nanoliposomal vesicles and

chitosan layering, product quality (structure, size) and manufacturing yield related to this novel method

were compared with those of the conventional dropwise method and the obtained products. The

proposed simil-microfluidic method led to the production of stable and completely chitosan-covered

liposomes with a shell–core nanostructure that avoided the disadvantages inherent in the conventional

method (which are time-consuming and/or require bulky and more expensive equipment).},

abstract = {Non-steroidal anti-inflammatory drugs (NSAIDs), i.e. indomethacin used for rheumatoid arthritis and non-rheumatoid inflammatory diseases, are known for their injurious actions on the gastrointestinal (GI) tract. Mucosal damage can be avoided by using nanoscale systems composed by a combination of liposomes and biodegradable natural polymer, i.e. chitosan, for enhancing drug activity.



Aim of this study was to prepare chitosan-lipid hybrid delivery systems for indomethacin dosage through a novel continuous method based on microfluidic principles. The drop-wise conventional method was also applied in order to investigate the effect of the two polymeric coverage processes on the nanostructures features and their interactions with indomethacin. Thermal-physical properties, mucoadhesiveness, drug entrapment efficiency, in vitro release behavior in simulated GI fluids and stability in stocking conditions were assayed and compared, respectively, for the uncoated and chitosan-coated nanoliposomes prepared by the two introduced methods.



The prepared chitosan-lipid hybrid structures, with nanometric size, have shown high indomethacin loading (about 10%) and drug encapsulation efficiency up to 99%. TEM investigation has highlighted that the developed novel simil-microfluidic method is able to put a polymeric layer, surrounding indomethacin loaded nanoliposomes, thicker and smoother than that achievable by the drop-wise method, improving their storage stability. Finally, double pH tests have confirmed that the chitosan-lipid hybrid nanostructures have a gastro retentive behavior in simulated gastric and intestinal fluids thus can be used as delivery systems for the oral-controlled release of indomethacin.



Based on the present results, the simil-microfluidic method, working with large volumes, in a rapid manner, without the use of drastic conditions and with a precise control over the covering process, seems to be the most promising method for the production of suitable indomethacin delivery system, with a great potential in industrial manufacturing.},

abstract = {In this work a protocol based on the microfluidic principles has been developed and applied to produce nanoliposomes. The protocol basically consists in the realization of a contact between two flows, lipids/ethanol and water solutions, inside a tubular device where interdiffusion phenomena allow the formation of lipid vesicles. Effects of solutions flow rates and lipids concentrations on size and size distribution have been investigated. Moreover, ultrasonic energy was used to enhance homogenization of the hydroalcoholic final solutions and to promote the vesicles size reduction. By this protocol a massive output has been achieved; increasing the ratio between the water volumetric flow rate to the lipids-ethanol volumetric flow rate the liposomes dimension decreases; at equal flow rates, when the lipids concentration increases also the liposomes size has been observed increasing. },
