The crystal structure of the title co-crystal, 2C(6)H(7)N(3)O·C(6)H(10)O(4), is a second polymorph, designated form II, of the co-crystal formed between the two mol-ecules [Lemmerer et al. (2011 ▶). CrystEngComm, 13, 55-59]. The asymmetric unit comprises one mol-ecule of nicotinic acid hydrazide, and one half-mol-ecule of adipic acid (the entire mol-ecule is completed by the application of a ce...

This study describes the synthesis of two new families of dendrimers based on the esterification of N-alkylated 3-amine-1-propanol with two different cores, adipic acid (1st and 2nd generations) and ethylenediamine (generation 1.5), both with carboxylic acid end groups, offering a wide variety of further modifications at the periphery. According to the cytotoxic evaluation of the dendrimers and...

Hexane-dioic acid (or adipic acid), C(6)H(10)O(4), crystallizes with two crystallographically independent half-mol-ecules in the asymmetric unit of the triclinic unit cell, space group P, as each mol-ecule lies across a crystallographic inversion centre. A monoclinic polymorph has been reported previously, most recently by Ranganathan, Kulkarni & Rao [J. Phys. Chem. A, (2003), 107, 6073-6081]. ...

Critical supersaturations for internally mixed particles of adipic acid, succinic acid and sodium chloride were determined experimentally for dry particles sizes in the range 40–130 nm. Surface tensions of aqueous solutions of the dicarboxylic acids and sodium chloride corresponding to concentrations at activation were measured and parameterized as a function of carbon content. The activation o...

Seeds of beans, lentils and peas were germinated for 2, 4 and 6 days, either under continuous light or continuous dark, and the free amino acids analysed by HPLC. The effects of germination on the free protein amino acids (FPA) and non-protein amino acids (FNPA) depended on the type of legumes and on the processing conditions. After germination of beans, histidine, glutamate, glycine, arginine,...

The ability of aerosol particles to take up water before supersaturated activation is defined as hygroscopic growth. The particle hygroscopic growth factor (HGF) is required for calculations of aerosol optical properties. To represent HGF in real environments, it is desirable to initialize a thermodynamic water uptake model with ambient aerosol measurements. The assumptions needed to adapt meas...

Organically-modified hydroxyapatite materials were synthesized through the addition of oxalic, succinic, adipic and citric acids to a calcium hydroxide solution before neutralization by ammonium dihydrogenphosphate. All carboxylic acids have a significant influence on apatite crystallinity and nanoparticle size, as indicated by XRD and TEM. Chemical and thermogravimetric analyses as well as FTI...

This work describes a new microfluidic device developed for the rapid screening of solubility diagrams. In several parallel channels, hundreds of nanolitre volume droplets of a given solution are first stored with a gradual variation in the solute concentration. Then, the application of a temperature gradient along these channels enables us to read directly and quantitatively phase diagrams, co...
