Comments on "Solubility and Dissolution Thermodynamic Data of Cefpiramide in Pure Solvents and Binary Solvents"
Abstract: Errors are found in the mathematical correlation based on the combined Jouyban-Acree and Modified Apelblat model for describing the variation in the mole fraction solubility of cefpiramide with temperature and solvent composition for the binary aqueous-ethanol solvent system. The equation coefficents given by Tang and coworkers, when substituted into the model equation, do not yield the authors' calculated mole fraction solubilities of cefpiramide.

Electrodynamics of superlattices with ultra-thin metal layers: quantum Landau damping and band gaps with nonzero density of states
This article develops a theory of electromagnetic transmission through dielectric-metal superlattices with ultra-thin metal films, in which electron motion in the direction perpendicular to the metal surfaces is quantized.

A novel benzimidazole derivative, MBIC inhibits tumor growth and promotes apoptosis via activation of ROS-dependent JNK signaling pathway in hepatocellular carcinoma
This study further explores a prior screening program carried out using MTT assay that identified a series of novel benzimidazole derivatives, among which Methyl 2-(5-fluoro-2-hydroxyphenyl)-1H-benzo[d]imidazole-5-carboxylate (MBIC) showed highest anticancer efficacy compared to that of chemotherapeutic agent, cisplatin. In this article, the authors find that MBIC inhibited cell viability in different hepatocellular carcinoma (HCC) cell lines without exerting significant cytotoxic effects on normal liver cells. The results of this study demonstrate that MBIC may inhibit cell proliferation via ROS-mediated activation of the JNK signaling cascade in HCC cells.

Engineered nonlinear materials using gold nanoantenna array
This article describes the use of a gold nanoantenna array to enhance both the nonlinear refractive index and two-photon absorption (2PA) of the organic dye 4,4'-bis(diphenylamino)stilbene (BDPAS), which is known as a dye with relatively large 2PA.

Artificially structured boundary for confinement of effectively unmagnetized cryogenic antimatter plasmas
The article is from conference proceedings that discuss an artificially structured boundary (ABS) considered to consist of a spatially periodic arrangement of electrostatically plugged magnetic cusps. As envisioned, a non-neutral positron plasma could be confined by an ASB along its edge, and the space charge of the positron plasma would serve to confine an antiproton plasma. If the conditions of the two-species plasma are suitable, production of antihydrogen via three-body recombination for antimatter gravity studies may be possible.

Multiple levers for overcoming the recalcitrance of lignocellulosic biomass
The article evaluates the impacts of physical, chemical and genetic interventions to improve biomass processing singly and in combination. Based on their results and literature studies, some form of non-biological augmentation will likely be necessary for the foreseeable future to achieve high total carbohydrate solubilization (TCS) for most cellulosic feedstocks. The results show that this need not necessarily involve thermochemical processing, and need not necessarily occur prior to biological conversion.

Magnetic plasma expulsion
The article presents one scheme for what is referred to as magnetic plasma expulsion, which would prevent the plasma from entering a given region. Magnetic plasma expulsion techniques may allow instrumentation access to the interiors of plasmas. Magnetic plasma expulsion techniques may also make alternative approaches for magnetic plasma confinement possible. Particle-in-cell simulation with the Warp code is used to study magnetic plasma expulsion. Some conditions for achieving magnetic plasma expulsion are reported.

Upper lethal temperatures of Northern Bobwhite embryos and the thermal properties of their eggs
This article explores the upper lethal temperature for Bobwhite eggs. Results find that thermal tolerances of Northern Bobwhite embryos are high, indicating an adaptation to the naturally occurring temperature extremes in the Bobwhite's environment. However, the results also indicate that high temperatures could have plausibly contributed to the population decline observed in the Bobwhite's semi-arid range.
