Abstract
Many bioactive nutraceuticals naturally occurring in food materials possess beneficial biological activities, while their use as functional supplements is subjected to hydrophobicity and crystallinity. Currently, inhibiting crystallization for such nutrients is of immense scientific interest. Here, we exploited diverse structural polyphenols as potential inhibitors for restraining Nobiletin crystallization. Specifically, the crystallization transition process could be influenced by the polyphenol gallol density, Nobiletin supersaturation (1, 1.5, 2, 2.5 mM), temperature (4, 10, 15, 25 and 37 ℃), and pH (3.5, 4, 4.5, 5), important factors for regulating the binding attachment and interactions. The optimized samples could be guided by NT100 lied in 4 ℃ at pH 4. Besides, the main assembly driving force was hydrogen-bonding cooperated with π-π stacking and electrostatic interaction, leading to a Nobiletin/TA combination ratio of ∼ 3:1. Our findings proposed an innovative synergistic strategy for inhibiting crystallization and broaden potential applications of polyphenol-based materials in advanced biological fields.

Abstract
To create genistein particles, a brand-new antisolvent recrystallization technique was employed. The response surface approach was utilized to optimize the single factor test findings, which were acquired via the preliminary tests. The ideal liquid-to-liquid ratio was 9, the solution concentration was 21 mg/mL, the nozzle diameter was 700 μm, the feed rate was 39.65 mL/min, and the homogenization rate was 1500 rpm. The smallest mean particle size measured was 202.782 nm. SEM was used to study the powder's morphology, while thermal analysis and infrared imaging were used to evaluate its characteristics. The homogeneous antisolvent recrystallization method-prepared GMP has a better dissolving rate and stronger antioxidant activity when compared to genistein powder. The antisolvent recrystallization approach used in this study, which uses low-speed homogenizing instead of conventional grinding and homogenizing, can successfully reduce particle size, improve bioavailability, and use less energy. This topic may thus be made popular because it has real-world applications.

Abstract
The low aqueous solubility and subsequently slow dissolution rate, as well as the poor bioavailability of several active pharmaceutical ingredients (APIs), are major challenges in the pharmaceutical industry. In this review, the particle engineering approaches using supercritical carbon dioxide (SC CO2) as an antisolvent are critically reviewed. The different SC CO2-based antisolvent processes, such as the gas antisolvent process (GAS), supercritical antisolvent process (SAS), and a solution-enhanced dispersion system (SEDS), are described. The effect of process parameters such as temperature, pressure, solute concentration, nozzle diameter, SC CO2 flow rate, solvent type, and solution flow rate on the average particle size, particle size distribution, and particle morphology is discussed from the fundamental perspective of the SAS process. The applications of the SAS process in different formulation approaches such as solid dispersion, polymorphs, cocrystallization, inclusion complexation, and encapsulation to enhance the dissolution rate, solubility, and bioavailability are critically reviewed. This review highlights some areas where the SAS process has not been adequately explored yet. This review will be helpful to researchers working in this area or planning to explore SAS process to particle engineering approaches to tackle the challenge of low solubility and subsequently slow dissolution rate and poor bioavailability.

Abstract
The present work reviews the liquid antisolvent crystallization (LASC) to prepare the nanoparticle of pharmaceutical compounds to enhance their solubility, dissolution rate, and bioavailability. The application of ultrasound and additives is discussed to prepare the particles with narrow size distribution. The use of ionic liquid as an alternative to conventional organic solvent is presented. Herbal compounds, also known for low aqueous solubility and limited clinical application, have been crystalized by LASC and discussed here. The particle characteristics such as particle size and particle size distribution are interpreted in terms of supersaturation, nucleation, and growth phenomena. To overcome the disadvantage of batch crystallization, the scientific literature on continuous flow reactors is also reviewed. LASC in a microfluidic device is emerging as a promising technique. The different design of the microfluidic device and their application in LASC are discussed. The combination of the LASC technique with traditional techniques such as high-pressure homogenization and spray drying is presented. A comparison of product characteristics prepared by LASC and the supercritical CO2 antisolvent method is discussed to show that LASC is an attractive and inexpensive alternative for nanoparticle preparation. One of the major strengths of this paper is a discussion on less-explored applications of LASC in pharmaceutical research to attract the attention of future researchers.

Abstract
Formamidinium lead triiodide (FAPbI3) perovskite quantum dots (PQDs) show great advantages in photovoltaic applications due to their ideal bandgap energy, high stability and solution processability. The anti-solvent used for the post-treatment of FAPbI3 PQD solid films significantly affects the surface chemistry of the PQDs, and thus the vacancies caused by surface ligand removal inhibit the optoelectronic properties and stability of PQDs. Here, we study the effects of different anti-solvents with different polarities on FAPbI3 PQDs and select a series of organic molecules for surface passivation of PQDs. The results show that methyl acetate could effectively remove surface ligands from the PQD surface without destroying its crystal structure during the post-treatment. The benzamidine hydrochloride (PhFACl) applied as short ligands of PQDs during the post-treatment could fill the A-site and X-site vacancies of PQDs and thus improve the electronic coupling of PQDs. Finally, the PhFACl-based PQD solar cell (PQDSC) achieves a power conversion efficiency of 6.4%, compared to that of 4.63% for the conventional PQDSC. This work provides a reference for insights into the surface passivation of PQDs and the improvement in device performance of PQDSCs.

Abstract
The dual regulation of water on lignin in ionic liquids was studied at the molecular level by molecular dynamics simulation. The simulation results show that a small amount of water will destroy the ion association in ionic liquids, that is, it will produce more free anions and cations. The free ions around lignin are conducive to the dissolution of lignin. On the contrary, excess water will seriously solvate anions and cations. By changing the number of lignin clusters, it is more intuitive to observe that the dissolution of lignin in ILs containing a small amount of water is stronger than that in pure IL, however, the dissolution ability of lignin is reduced after adding a large amount of water in ILs. It is concluded that with the increase of water content, water changes from co-solvent to anti-solvent in the dissolution process. This study provides ideas for the design of IL-water system for economic pretreatment of biomass.

Abstract
Liquefied dimethyl ether (DME) was employed as an antisolvent to crystallize glycine from its aqueous solution. The proposed method can be performed at 20–25 °C and has the potential to reduce the energy consumption of drying or crystallizing using ethanol. α-Glycine crystals were successfully obtained from glycine aqueous solutions by mixing in liquefied DME, which was easily removed from the crystals by decompression. Contact with a liquefied DME/water mixture and small γ-glycine crystals resulted in the α-glycine converting to γ-glycine. This was only observed for saturated glycine solutions. We speculated that this conversion occurs via a solution-mediated transition. Pure liquefied DME is not capable of promoting solvent-mediated transitions, so saturated glycine solutions treated with the pure antisolvent can give α-glycine as the sole product.

Abstract
Recovery of lactose from the whey using sonocrystallization was studied experimentally. The effect of sonication medium and irradiation power levels was evaluated using three different ultrasonic equipments. Effects of various parameters such as sonication time, pH of the medium, antisolvent (acetone and acetone-ethanol mixture) and concentration of lactose were determined. The optimal parametric conditions were analyzed using differential scanning calorimetry, thermogravimetric analysis, particle size distribution, and zeta potential measurements. Overall, the highest lactose recovery was obtained using a mixture of acetone and ethanol as antisolvent in bath sonication as well as atomization process.

Abstract
Gold nanoparticles (Au NPs) were synthesized by reducing HAuCl4 using borane tert-butylamine complex in the presence of alkylamine (dodecylamine, hexadecylamine, and octadecylamine) and didodecyldimethylammonium bromide. Ethanol was used as an antisolvent for the postsynthesis purification of Au NPs. Au NPs had uniform size distribution after first wash with ethanol and the aggregation and growth of Au NPs happened after second wash with ethanol. The Au NPs were characterized by TEM, SEM, XRD, 1H NMR, UV-vis absorption and FTIR spectroscopy. The aggregated mechanism after the second wash with ethanol was proposed. Au NPs still retained their monodispersity after second wash compared with after first wash using the antisolvents, such as acetonitrile, dimethyl sulfoxide and acetone. The presented results suggest that the good choice of antisolvent is critical for the postsynthesis purification of Au NPs.

Abstract
Pharmaceutical cocrystals are multicomponent systems composed of two or more molecules and held together by H-bonding. Currently, cocrystals provide exciting opportunities in the pharmaceutical industry for the development and manufacturing of new medicines by improving poor physical properties of Active Pharmaceutical Ingredients (APIs) such as processability, solubility, stability and bioavailability. According to the recent reclassification, cocrystals are considered as drug polymorph rather a new API which has a significant impact on drug development, regulatory submissions and intellectual property protection. This review summarizes recent trends and advances in synthesis, manufacturing and scale - up of cocrystals. The operational principles of several cocrystals manufacturing technologies are discussed including their advantages and disadvantages in terms of crystal quality, purity stability, throughput and limitations in large scale production.

Abstract
This research aimed to develop the omega-3 phospholipids based solid dispersion to improve the oral bioavailability of fenofibrate. The omega-3 phospholipids based solid dispersion formulation (OPSD) was prepared by an antisolvent precipitation with immediate freeze-drying and the optimal composition of the formulation was determined as the ratios of sucrose to krill oil of 5:1 (w/w), krill oil to fenofibrate of 1.5:1 (w/w), and antisolvent to solvent of 6:4 (v/v). The developed OPSD formulation was characterized by using scanning electron microscopy (SEM), X-ray powder diffraction (XRPD), and differential scanning calorimetry (DSC), which indicated the crystalline state of fenofibrate in the OPSD. The drug release profiles were also examined at different pHs. The OPSD achieved almost complete dissolution within 15 min, while the untreated powder and physical mixture exhibited minimal dissolution (less than 10% even after 2h). Furthermore, this formulation effectively increased the oral drug exposure in rats, as the Cmax and AUC of fenofibric acid (an active metabolite) were enhanced by approximately 6-7 folds. These results suggest that the OPSD formulation should be promising for improving the oral bioavailability of fenofibrate.

Abstract
The present work aims to investigate applicability of antisolvent precipitation method for preparation of nanosized curcumin and to control their characteristics by determining the influence of process and solvents on solid-state properties of curcumin nanoparticles. Effects of different experimental parameters on particle size were investigated using dynamic light scattering. Particle morphology was studied using SEM. Drug content in stabilized nanoparticles was determined using HPLC. Residual moisture content after lyophilisation was determined using Karl Fischer method and solid state properties were investigated using DSC, TGA, FTIR and powder-XRD. The resulting product showed a high drug load and contained the drug in amorphous form. The particle diameters of prepared curcumin nanoparticles were found in the range of 100-200 nm. In vitro drug release studies indicated a sustained release profile of curcumin from the nanoparticles. Antisolvent precipitation produced amorphous curcumin nanoparticles whose size and morphology could be controlled using gelatine as stabilizer. Lyophilized curcumin nanoparticles with d-sorbitol as lyoprotectant possessed good redispersibility and showed up to 4 times faster in vitro curcumin release rate than that of unprocessed curcumin. Stability tests (at 2-8°C and ambient conditions) indicated that the product was stable for up to 6 months of storage.
