Significant progress in predicting the crystal structures of small organic molecules - A report on the fourth blind test
(Wiley Blackwell Publishing, Inc, 2009-02)
We report on the organization and outcome of the fourth blind test of crystal structure prediction, an international collaborative project organized to evaluate the present state in computational methods of predicting the ...
Cellulose nanocrystals in aqueous suspensions: rheology of lyotropic chiral liquid crystals
(Springer, 2019-01)
A thorough rheological study of the behavior of cellulose nanocrystals (CNC) in water was undertaken, focusing on the main characteristics of rod-like suspensions that allign under flow and can display liquid crystal ...
A detailed experimental and theoretical study of two novel substituted trifluoromethylchromones. The influence of the bulky bromine atom on the crystal packing
(Pergamon-Elsevier Science Ltd, 2015-02)
(Figure Presented) The new 3-methyl-2-trifluoromethylchromone (1 ) and 3-bromomethyl-2-trifluoromethylchromone (2) compounds were synthesized and characterized by vibrational (IR, Raman), UV-Vis and NMR (1H, 13C and 19F) ...
Hydroxyapatite Nanoparticle Mesogens: Morphogenesis of pH-Sensitive Macromolecular Liquid Crystals
(American Chemical Society, 2021-03)
Numerous living structural materials display self-assembly of building blocks. Biological molecular networks exhibit lyotropic liquid crystalline properties that can support non-equilibrium pathways influenced by dynamic ...
Stable calcium isotope speciation and calcium oxalate production within beech tree (Fagus sylvatica L.) organs
(Springer, 2018-01-04)
In this study, we linked Ca speciation with isotope composition in plants. To do this, we performed leachate experiments to access the soluble Ca, structurally bound Ca and insoluble Ca (i.e., water and weak acid resistant) ...
Effect of Keggin polyoxometalate on Cu(ii) speciation and its role in the assembly of Cu3(BTC)2 metal-organic framework
(Royal Society of Chemistry, 2011-07)
HKUST-1 is one of the popular metal-organic frameworks (MOFs). The formation of this MOF is significantly accelerated by adding Keggin polyoxometalate anions to the synthesis solution. In this paper the chemistry behind ...
Socio-cultural interaction and symbolism in prehistoric South America: Quartz crystal manuports from Tierra del Fuego
(IntechOpen, 2019)
The use of mineral elements with special characteristics, such as quartz crystals, in ornamental or ceremonial contexts, is not uncommon in archaeology. Their appearance in different archaeological sites is the basis to ...
