Biomass DNA: An Emerging Building Block for Advanced Materials

open access: yesAdvanced Materials, EarlyView.
Biomass DNA is rapidly emerging from its traditional role as a genetic blueprint to serve as a versatile abundant, highly programmable polymeric building block. This review highlights the transformation of macroscopic bulk biomass DNA into next generation of functional materials, spanning from dynamic hydrogels, sustainable bioplastics, and high ...

Conversion of fatty aldehyde dimethyl acetals to the corresponding alk-1-enyl methyl ethers (substituted vinyl ethers) during gas-liquid chromatography

open access: yesJournal of Lipid Research, 1967
The behavior of palmitaldehyde and linolealdehyde and of their dimethyl acetals during gas-liquid chromatography on Β-cyclodextrin acetate (Β-CDX acetate) and ethylene glycol succinate polyester-phosphoric acid (EGSP) columns was studied.

Methyl aryl ethers from coal liquids as gasoline extenders and octane improvers [PDF]

open access: yes, 1980
A mixture of methyl aryl ethers derived from the phenols present in direct liquefaction coal liquids shows considerable promise as a gasoline blending agent and octane improver.

An Oxidation of Benzyl Methyl Ethers with NBS that Selectively Affords Either Aromatic Aldehydes or Aromatic Methyl Esters

open access: yes, 2016
Either mono- or dibromination of benzyl methyl ethers can be achieved by controlling the amount of NBS and the temperature. Elimination of methyl bromide from the monobrominated intermediates produces aromatic aldehydes, whereas hydrolysis of the ...

Mechanoactive Biomaterials for Cell–Matrix Mechanotransduction

open access: yesAdvanced Materials, EarlyView.
The graphical abstract shows how individual triggers (force, light, or temperature) and combined optothermal or receptor‐targeted actuation induce material responses at the tissue, cellular, and receptor scales. Their spatial (global or focused) and temporal (continuous or cyclic) modulation determines the resulting mechanical output.

In-Solution Conformational Analysis of the XCYCH3 Moiety for Small Esters and Ethers with all Combinations of X, Y = O, S

open access: yesMolecules, 2013
Favorable steric and electrostatic fit of a ligand to a receptor is of central interest in theoretical drug design. This paper considers the effects of non-protic solvents, in comparison with the gas phase, on the preferred conformation of the XCYCH3 ...

Amphiphilic Non‐Isocyanate Polyurethane Coatings With Tunable Antifouling and Fouling‐Release Performance: A Log‐Ratio Assessment Framework

open access: yesAdvanced Materials Interfaces, EarlyView.
Amphiphilic non‐isocyanate polyurethane (NIPU) coatings containing reactive hydrophobic poly(dimethylsiloxane) (PDMS) and hydrophilic methoxy poly(ethylene glycol) (MPEG) prepolymers for marine antifouling (AF) and fouling‐release (FR) applications were investigated. The coatings were evaluated with a set of representative marine foulants.
