A Stable Phosphanyl Phosphaketene and Its Reactivity

02-Mar-2015 | H Grutzmacher; Zhongshu Li; Chengyong Su; Xiaodan Chen; Maike Bergeler; Markus Reiher, Dalton Transactions, 2015

Sodium phospaethynolate, Na(OCP), reacts with the bulky P-chloro-diazaphosphole yielding a phosphanyl phosphaketene, which is stable for weeks under inert atmosphere in the solid state. This compound is best described as tight ion pair with a remarkable long P–P bond distance (2.44 Å). In ...

Influence of Sodium Metabisulfite and Citric Acid in Soaking Process after Blanching on Quality and Storage Stability of Dried Chili

27-Feb-2015 | Kwanhathai Chaethong, Rungnaphar Pongsawatmanit, Journal of Food Processing and Preservation, 2015

Abstract Influence of sodium metabisulfite (Na2S2O5) and citric acid in soaking solution was investigated for enhancing dried chili quality. Fresh chili samples were blanched and soaked in nine solutions of Na2S2O5 and citric acid for 30 min before drying at 65C. Soaking with Na2S2O5 and ...

Influence of Sodium Salts on the Micellization and Interfacial Behavior of Cationic Surfactant Dodecyltrimethylammonium Bromide in Aqueous Solution

23-Feb-2015 | Hossein Hooshyar; Rahmat Sadeghi, Journal of Chemical & Engineering Data, 2015

Micellar and surface properties of aqueous dodecyltrimethylammonium bromide (DTAB) solutions have been studied in the absence and presence of several sodium salts including NaCl, NaH2PO4, Na2HPO4, Na2CO3, Na2SO4, Na3PO4, and Na3Cit. The values of critical micelle concentration (cmc), degree of ...

The effects of pH and surfactants on the absorption and fluorescence properties of ochratoxin A and zearalenone

18-Feb-2015 | Taihua Li, Bo Bae Kim, Tae Hwan Ha, Yong‐Beom Shin, Min‐Gon Kim, Luminescence, 2015

ABSTRACT The pH and surfactant dependencies of the absorption and fluorescence properties of ochratoxin A (OTA) and zearalenone (ZEN), the main mycotoxins found as contaminants in foods and feeds, were evaluated. Three surfactants with different ionic properties were investigated, namely ...

Atomic-Scale Recognition of Surface Structure and Intercalation Mechanism of Ti3C2X

17-Feb-2015 | Xuefeng Wang; Xi Shen; Yurui Gao; Zhaoxiang Wang; Richeng Yu; Liquan Chen, Journal of the American Chemical Society, 2015

MXenes represent a large family of functionalized two-dimensional (2D) transition-metal carbides and carbonitrides. However, most of the understanding on their unique structures and applications stops at the theoretical suggestion and lack of experimental support. Herein, the surface structure ...

Nitrocobinamide, a New Cyanide Antidote That Can Be Administered by Intramuscular Injection

16-Feb-2015 | Adriano Chan; Jingjing Jiang; Alla Fridman; Ling T. Guo; G. Diane Shelton; Ming-Tao Liu; Carol Green; Kristofer J. H ..., Journal of Medicinal Chemistry, 2015

Currently available cyanide antidotes must be given by intravenous injection over 5–10 min, making them ill-suited for treating many people in the field, as could occur in a major fire, an industrial accident, or a terrorist attack. These scenarios call for a drug that can be given quickly, e.g., ...

Dynamics of Dihydrogen Bonding in Aqueous Solutions of Sodium Borohydride

16-Feb-2015 | Chiara H. Giammanco; Patrick L. Kramer; Michael D. Fayer, Journal of Physical Chemistry B, 2015

Dihydrogen bonding occurs between protonic and hydridic hydrogens which are bound to the corresponding electron withdrawing or donating groups. This type of interaction can lead to novel reactivity and dynamic behavior. This paper examines the dynamics experienced by both borohydride and its ...

How Does the Surface Charge of Ionic Surfactant and Cholesterol Forming Vesicles Control Rotational and Translational Motion of Rhodamine 6G Perchlorate (R6G ClO4)?

16-Feb-2015 | Surajit Ghosh; Arpita Roy; Debasis Banik; Niloy Kundu; Jagannath Kuchlyan; Anjali Dhir; Nilmoni Sarkar, Langmuir, 2015

The rotational dynamics and translational diffusion of a hydrophilic organic molecule, rhodamine 6G perchlorate (R6G ClO4) in small unilamellar vesicles formed by two different ionic surfactants, cetyltrimethylammonium bromide (CTAB) and sodium dodecyl sulfate (SDS), with cholesterol have been ...

Exploring Molecular Insights into Aggregation of Hydrotrope Sodium Cumene Sulfonate in Aqueous Solution: A Molecular Dynamics Simulation Study

10-Feb-2015 | Shubhadip Das; Sandip Paul, Journal of Physical Chemistry B, 2015

Hydrotropes are an important class of molecules that enhance the solubility of an otherwise insoluble or sparingly soluble solute in water. Besides this, hydrotropes are also known to self-assemble in aqueous solution and form aggregates. It is the hydrotrope aggregate that helps in solubilizing ...
