Frederica Mathewes-Green reads her essay, "Why They Hate Us."

Fr. Michael shares his concerns with the familiar "Poop in the Brownies" story and offers some positive alternatives to talking about purity with children.

Dr. John Behr, the Dean of St. Vladimir's Orthodox Theological Seminary, Dr. Bishop Anba Suriel of the Coptic Diocese of Melbourne, Dean of St. Athanasius Coptic Orthodox Theological College, Australia, and the Very Rev. Fr. Dr. Athanasius K. Farag, Dean of Pope Shenouda III Coptic Orthodox Theological Seminary, speak at the book launch of the new SVS Press book by Pope Shenouda The Life of Repentance and Purity.

Fr. Apostolos shares about sexual purity. "We cannot, we dare not, manufacture a false gospel that dismisses chastity and sexual purity because maintaining them is difficult."

Today Dr. Rossi interviews Bishop John (Abdalah) of the Antiochian Archdiocese on the subject of purity.

Dr. Rossi address issues of the purity of the heart and mind in relation to sexual chastity.

In this homily based upon Matthew 6:22-33, Fr. Pat looks at three things necessary for us to have purity of heart.

This study proposes an operation optimization framework for impurity-free recycling of spent lithium-ion batteries. Using a hybrid population balance equation integrated with a data-driven condition classifier, the study firstly identifies the optimal batch and semi-batch operation conditions that significantly reduce the operation time with 100% purity of product; detailed guidelines are given for industrial applications.

Thanks to their new 22,000-sq.-ft. production facility in Cudahy, Wis., the folks at Angelic Bakehouse now have the room, additional equipment and the structure they need to efficiently produce sprouted whole-grain breads, buns, rolls and flatbread/pizza crusts using an unusual process.

In their comment (1) on our publication (2), the authors make two points: (i) they raise concerns about the possible effect of residual NONOate in our study, and (ii) they promote nitrosylcobalamin (NOCbl) supplied by their own company. Both points lack merit for the following reasons. The authors make the astonishing claim that the spectra of nitric oxide (NO•) and cobalamins overlap. Unlike NO•, cobalamin absorbs in the visible region, permitting unequivocal spectral assignment of NOCbl as reported (3). We demonstrated that whereas NOCbl is highly unstable in solution, it is stabilized by the B12 trafficking protein CblC. So even if present, residual NONOate (which is unstable at neutral pH and is removed during the work-up (3)) could not account for the observed difference.The authors then misrepresent our synthetic method, claiming that anaerobic conditions were used to generate nitrocobalamin (NO2Cbl), which results in the transient formation of NOCbl. We synthesized NO2Cbl aerobically using nitrite as described (4); NOCbl is not an intermediate in this ligand exchange reaction. The aerobic instability of NOCbl has been rigorously described by inorganic chemists (3, 5) and raises obvious questions about its purported biological effects as exemplified by the authors' own 2003 JBC publication, which was later withdrawn.As to promoting NOCbl from their company, the authors refer to a synthetic route from a mixture of NO• gas and aquocobalamin. The authors' method (6) has been described as “dubious” by chemists (5). Whereas DEAE NONOate used in our method is widely known as an NO• donor,...

After a thorough read of this paper (1), we wish to clarify that the authors' anaerobic method of synthesis for the production of nitrocobalamin results in the transient formation of nitrosylcobalamin, an unstable intermediate upon exposure to air. We concur that the authors' method results in the production of nitrocobalamin based on the UV-visible data as shown. The authors' adapted anaerobic method consists of mixing hydroxocobalamin hydrochloride with diethylamine NONOate diethylammonium salt in aqueous solution. Of concern, the UV spectrum of nitric oxide overlaps that of all cobalamin species under anaerobic conditions, making any assignments of the binding of nitric oxide to hydroxocobalamin suspect (2). Additionally, the use of acetone to precipitate the authors' product causes precipitation of diethylamine NONOate, resulting in an impure product. As a result, its utility for drawing experimental conclusions is faulty.The product from the authors' anaerobic synthetic method has not been assessed for purity, and the synthetic method itself has not been validated using a stability-indicating method as required by the International Conference on Harmonization (ICH) (ICH Q2B, Validation of Analytical Procedures) methodology, which is a hallmark for analytical characterization. Our nitrosylcobalamin synthesis involves reacting nitric oxide gas with hydroxocobalamin acetate as a heterogeneous mixture in a non-electron-donating solvent followed by rotary evaporation. Our nitrosylcobalamin product is stable in air, releases nitric oxide gas in situ (3), and meets ICH stability guidelines (4). Additionally, our nitrosylcobalamin product demonstrates biological activity, which has not been observed for nitrocobalamin (3, 5).

A process for producing a high-purity dimethyl carbonate, which includes: (I) cooling a commercial grade dimethyl carbonate containing 1 ppm or more of chlorine to a temperature from +6° C. to −5° C. at a rate from 0.5-2° C./hour, to obtain a first solid dimethyl carbonate; (II) heating the first solid dimethyl carbonate to a temperature from −5° C. to +6° C. at a rate of 1-5° C./hour, to obtain a mixture comprising a second solid dimethyl carbonate and a predetermined amount of a first liquid dimethyl carbonate; (III) separating the first liquid dimethyl carbonate from the mixture, to obtain the second solid dimethyl carbonate; (IV) heating the second solid dimethyl carbonate to a temperature from 20° C. to 40° C., to obtain a second liquid dimethyl carbonate, wherein the second liquid dimethyl carbonate has a purity degree higher than 99.99% and a chlorine content lower than or equal to 1 ppm.

A method for preparing a high purity (e.g. greater than 70 wt. %) mono-hydrolyzed acyl halide compound as a precipitate from solution comprising the steps of preparing a solution comprising: i) at least 80 v/v % of a hydrocarbon solvent, ii) water at a molar concentration greater than its solubility limit within the solvent but less that its solubility limit in solution, iii) a tri-hydrocarbyl phosphate compound, and iv) a polyfunctional acyl halide compound at molar ratio to both water and the tri-hydrocarbyl phosphate compound of at least 1:1.

There are provided a dividing wall distillation column for producing high-purity acrylic acid, and a fractional distillation method using the same. The dividing wall distillation column includes a condenser, a reboiler and a main column having a dividing wall. Here, the main column is divided into a column-top zone, an upper feed zone, an upper outflow zone, a lower feed zone, a lower outflow zone and a column-bottom zone. Accordingly, since one distillation column can be used to realize the same effect as that obtained from the use of two distillation columns, the dividing wall distillation column can have an effect of reducing the costs of equipment to produce high-purity acrylic acid, as well as an energy-reducing effect, compared to a conventional process system.
