Novel On-Demand 3-Dimensional (3-D) Printed Tablets Using Fill Density as an Effective Release-Controlling Tool by Rishi Thakkar, Amit Raviraj Pillai, Jiaxiang Zhang, Yu Zhang, Vineet Kulkarni, Mohammed Maniruzzaman

“…The purpose of this research was to understand the impact of fill density and interrelate it with the release of a poorly water-soluble, weakly acidic, active pharmaceutical ingredient (API) from a hydroxypropyl methylcellulose acetate succinate (HPMC-AS) matrix, both mathematically and experimentally. Amorphous solid dispersions (ASDs) of ibuprofen with three grades of AquaSolve^TM HPMC-AS (HG, MG, and LG) were developed using an HME process and evaluated using solid-state characterization techniques. …”

Simulated phase state and viscosity of secondary organic aerosols over China by Z. Zhang, Z. Zhang, Y. Li, Y. Li, H. Ran, H. Ran, J. An, J. An, Y. Qu, Y. Qu, W. Zhou, W. Xu, W. Xu, W. Hu, H. Xie, Z. Wang, Z. Wang, Y. Sun, Y. Sun, M. Shiraiwa

“…<p>Secondary organic aerosols (SOAs) can exist in liquid, semi-solid, or amorphous solid states. Chemical transport models (CTMs), however, usually assume that SOA particles are homogeneous and well-mixed liquids, with rapid establishment of gas–particle equilibrium for simulations of SOA formation and partitioning. …”

Structural rationale for boson peak in metallic glass informed by an interpretable neural network model by Jia-Le Tao, Zeng-Yu Yang, Yun-Jiang Wang

“…In amorphous solids, there exists a universal phenomenon of vibrational anomaly, i.e., an excess of vibrational modes over the Debye level in the low-terahertz-frequency regime, which is termed a boson peak. …”

Novel lead(IV) reagents for carbon-carbon bond formation by Moloney, M, Thompson, R, Wright, E

“…These compounds have been found to be stable amorphous solids, but upon reaction with phenylboronic acid and a variety of β-dicarbonyl substrates with mercury(II) catalysis, carbon-carbon bond formation can be readily achieved.…”

pH-Dependent Crystallization of 2-, 4-, 5-, and 6-Hydroxynicotinic Acids in Aqueous Media by Aidan V. Johnson, M. Fátima M. Piedade, Catarina V. Esteves

“…The crystallization outcome was quite diverse: individual crystals of different sizes and shapes, microcrystalline powders, crystalline aggregates, and almost amorphous solids. Such a variety of solid forms demonstrates the relevance of pH control during crystallization processes.…”

Drying of sodium silicate solutions by Dent Glasser, L. S., Lee, C. K.

“…Sodium silicate solutions with a silicon dioxide:sodium monoxide mole ratio of 3.41:1 were dried gently to give amorphous solids. These solids, together with the products obtained by heating them at various temperatures up to ∼ 200°c, were studied by differential thermal analysis, solubility tests and other techniques. …”

Dielectric and Elastic Characterization of Nonlinear Heterogeneous Materials by Stefano Giordano

“…Both phases are considered isotropic (actually it means polycrystalline or amorphous solids). Under the simplifying hypotheses of small deformation for the material body and of small volume fraction of the embedded phase, we describe a theory for obtaining the linear and nonlinear elastic properties (bulk and shear moduli and Landau coefficients) of the overall material.…”
