It is determined that the synthesis of PHAs was not due to a complete lack of nitrogen source, as previously reported for other microorganisms, and it depended on the carbon/nitrogen ratio in the culture.
SYNTHESIS AND CHARACTERIZATION OF POLY (METHYL METHACRYLATE-STYRENE) COPOLYMERIC BEADS FOR BONE CEMENTS
Acrylic bone cements have been used for about 40 years to fix artificial prosthesis to bone structure. The properties of the acrylic bone cement mostly depend on the characteristics of the beads,…
Two glucosylated abscisic acid derivates from avocado seeds (Persea americana Mill. Lauraceae cv. Hass).
Reactions, characterization and uptake of ammoxidized kraft lignin labeled with 15N.
A NEW INTERFIBRE SYSTEM FOR PAPER INVOLVING ZWITTERIONS
This paper examines the effects of the natural ability of the fibres to bond and the introduction of moieties able to provide balanced ionic interactions, on the dry and wet mechanical properties of…
Sisal Chemo-Thermomechanical Pulp Paper with a Strongly Hydrophobic Surface Coating Produced by a Pentafluorophenyldimethylsilane Cold Plasma
Fluorinated thin layers were created on CTMP sisal and filter paper surfaces by using pentafluoro- phenyldimethylsilane (PFPDMS) under RF-plasma condi- tions. Surface wettability and water absorption…
A new bilayer chitosan scaffolding as a dural substitute: experimental evaluation.

Comparison with the 13C and 15N chemical shifts of l-leucine lyophilized at different pH shows that the aminocarboxyl groups of LysCel are indeed zwitterionic, in contrast to the gas phase, where amino acid dimers exhibiting two OHN hydrogen bonds are neutral.

Two materials, pure poly(acrylic acid) (PAA) and nanocomposites with a matrix of PAA and carbon nanotubes (CNTs) as reinforcing agent were synthesized by semi-continuous heterophase polymerization…
C-26 and C-30 apocarotenoids from seeds of Ditaxis heterantha with antioxidant activity and protection against DNA oxidative damage.
The hexane extracts of seeds of Ditaxis heterantha afforded two new apocarotenoids whose structures corresponded to methyl 3-oxo-12'-apo-epsilon-caroten-12'-oate (1) (heteranthin) and methyl…
