Thermochemical Properties and Regularities of Amides, Anilides, and Amidic Acids

open access: yesActa Chimica Slovenica, 2018
The thermodynamic properties of carbamide and its alkyl substituted were studied insufficiently. In this article, the enthalpies of combustion of ΔсН of some amides, anilides and amidic acids have been determined experimentally; their standard enthalpies of formation have been calculated.

Bioorthogonal Engineering of Cellular Microenvironments Using Isonitrile Ligations

open access: yesAdvanced Functional Materials, EarlyView.
Highly selective chemistries are required for fabrication and post‐cross–linking modification of cell‐encapsulating hydrogels used in tissue engineering applications. Isonitrile ligation reactions represent a promising class of bioorthogonal chemistries for engineering hydrogel‐based cellular microenvironments. Isonitrile‐based hydrogels are stable and

Amide-modified poly(butylene terepthalate): thermal stability [PDF]

open access: yes, 1996
The thermal stability of a poly(ester amide) copolymer (PBTA) based on poly(butylene terephthalate) (PBT) and nylon-4,T with the diamide of butanediamine and dimethyl terephthalate (N,N′-bis(p-carbomethoxybenzoyl)butanediamine) and homopolymer PBT was ...

Polar Pore Surface of Polyamide Membranes Enabling Efficient Solvent Mixture Separation

open access: yesAdvanced Functional Materials, EarlyView.
A polyamide membrane with polar pore surfaces and relatively large pore is fabricated through interfacial polymerization between polyethyleneimine and trimesoyl chloride. Rapid separation of solvents with polarity differences is achieved by the synergistic effects of pore polarity and size sieving.

Multi‐Scaled Cellulosic Nanonetworks from Tunicates

open access: yesAdvanced Functional Materials, EarlyView.
Microbial and plant nanonetworks of cellulose have enabled a wide range of high‐performance yet sustainable materials. Herein, a third class of cellulosic nanonetworks is showcased by exploiting the only animal tissue‐producing cellulose nanofibers, i.e., ascidians. An ultrastructure including spherical cells and a microvasculature with diameters of 50–

Reactions of (-)-sparteine with alkali metal HMDS complexes : conventional meets the unconventional [PDF]

open access: yes, 2009
Conventional (-)-sparteine adducts of lithium and sodium 1,1,1,3,3,3-hexamethyldisilazide (HMDS) were prepared and characterised, along with an unexpected and unconventional hydroxyl-incorporated sodium sodiate, [(-)-sparteine·Na(-HMDS)Na·(-)-sparteine]+[

Experimental Atom-by-Atom Dissection of Amide–Amide and Amide–Hydrocarbon Interactions in H2O [PDF]

open access: yesJournal of the American Chemical Society, 2017
Quantitative information about amide interactions in water is needed to understand their contributions to protein folding and amide effects on aqueous processes and to compare with computer simulations. Here we quantify interactions of urea, alkylated ureas, and other amides by osmometry and amide-aromatic hydrocarbon interactions by solubility ...
