Multilayers of poly(acrylic acid), PAA, and chitosan, CHI, have been built by the layer-by-layer (LbL) method from aqueous solutions at different pH values and analyzed by the dissipative quartz crystal microbalance (D-QCM) and ellipsometry. The results showed that under all of the assembly conditions considered the growth of the films is nonlinear. The(More)
We describe a patient with limb girdle muscular dystrophy with evidence of a D596N novel mutation of the LMNA gene. He presented with a dilated cardiomyopathy and heart failure. He successfully underwent a cardiac rehabilitation program without cardiovascular complications. Clinicians should suspect a variety of a wide array of diseases including(More)
NMR is a fast, nondestructive, and noninvasive technique that can provide information about the pore structure of macroporous polymer beads and the dynamics of liquids confined in them. In this work, we describe the study of the pore structure of the macroporous polymer of ethylene glycol dimethacrylate and 2-hydroxyethyl methacrylate [poly(EGDMA-co-HEMA)](More)
Evaporation kinetics of water confined in hierarchal polymeric porous media is studied by low field nuclear magnetic resonance (NMR). Systems synthesized with various degrees of cross-linker density render networks with similar pore sizes but different response when soaked with water. Polymeric networks with low percentage of cross-linker can undergo(More)
Graphitic carbon nitride (g-C3N4) was synthesized from a low-cost precursor by means of a thermal process. The product was characterized by several spectroscopic techniques and the crystallinity was analyzed by X-ray diffraction. In the manufacture of the sensor, g-C3N4 was chemically exfoliated and a film was placed on the surface of a Highly Oriented(More)
The influence of the polymeric morphology of different types of Fe(3+)-containing sorbents and their properties in retention of phosphoamino acids is presented in this paper. Poly(hydroxylated polybutadienic-hydroxyethyl methacrylate) [poly(PB-HEMA)] and poly(ethylene glycol dimethacrylate-hydroxyethyl methacrylate) [poly(EGDMA-HEMA)] base supports were(More)
The influence of the morphology of ethylene glycol dimethacrylate-hydroxyethyl methacrylate copolymer [poly(EGDMA-co-HEMA)] base support to obtain different Fe(3+)-containing sorbents and their properties in retention of O-phosphothreonine [Thre(P)] is examined in this paper. Three base supports poly(EGDMA-co-HEMA) (I-III) were obtained using different(More)
Hierarchical porous polymer systems are increasingly applied to catalysis, bioengineering, or separation technology because of the versatility provided by the connection of mesopores with percolating macroporous structures. Nuclear magnetic resonance (NMR) is a suitable technique for the study of such systems as it can detect signals stemming from the(More)
