“…This peak increase is consistent with MA weight percentage, so the MA grafting level was measured from the intensity of 1780 cm À1 , and the thickness variation of each sample was corrected by 2019 cm À1 intensity for internal reference peak. 24 Figure 3 shows the peak ratio of 1780/2019 cm À1 as a function of PE-g-MA content. MA weight percentages calculated by peak ratio are summarized in Table I.…”

“…The peak at 3.60 ppm corresponds to the methylester-group found in PMMA [37]. The peaks in the region between δ = 2.2 ppm and 1.3 ppm are significant for the CH 2 -group [38].…”

“…The sum of their integral intensity equals that of the peak at δ = 3.60 ppm. The peaks in the region between δ = 2.2 ppm and 1.3 ppm are significant for the CH 2 -group [37]. Differences between the bulk and capillary bridge samples occur in this δ-range, which are presumably due to impurities inferred from the preparation of the capillary suspension.…”

We present a generic and versatile low temperature route to produce macro-porous bodies with porosity and pore size distribution that are adjustable in a wide range. Capillary suspensions, where the minor fluid is a monomer, are used as pre-cursors. The monomer is preferentially located between the particles, creating capillary bridges, resulting in a strong, percolating network. Thermally induced polymerization of these bridges at temperatures below 100 °C for less than 5 hours and subsequent removal of the bulk fluid yields macroscopic, self-supporting solid bodies with high porosity. This process is demonstrated using methylmethacrylate and hydroxyethylmethacrlyate with glass particles as a model system. The produced PMMA had a molecular weight of about 500.000 g/mol and dispersity about three. Application specific porous bodies, including PMMA particles connected by PMMA bridges, micron-sized capsules containing phase change material with high inner surface, and porous graphite membranes with high electrical conductivity, are also shown.

“…The use of MRS is limited to these and several other nuclei, based on their physical properties, that is, possessing a resonance frequency that responds, or aligns, within a magnetic field, and the release of energy after perturbation following application of an RF pulse, all of which make these nuclei MR visible. For a given nucleus (e.g., 1 H), chemically distinct groups within a molecule that contain the given nucleus possess minor differences in their local resonant frequencies owing to the inhomogeneous and unique distribution of electrons within the molecule (Bovey, Jelinski, & Mirau, 1988). These small differences in resonant frequency, or chemical shift, make it possible to differentiate molecules based on their distinct spectral signatures (e.g., Figure 1, 1 H spectrum; Figure 2, 31 P spectrum).…”

Contributions of magnetic resonance spectroscopy to understanding development: Potential applications in the study of adolescent alcohol use and abuse

A growing body of research has documented structural and functional brain development during adolescence, yet little is known about neurochemical changes that occur during this important developmental period. Magnetic resonance spectroscopy (MRS) is a well-developed technology that permits the in vivo quantification of multiple brain neurochemicals relevant to neuronal health and functioning. However, MRS technology has been underused in exploring normative developmental changes during adolescence, and the onset of alcohol and drug use and abuse during this developmental period. This review begins with a brief overview of normative cognitive and neurobiological development during adolescence, followed by an introduction to MRS principles. The subsequent sections provide a comprehensive review of the existing MRS studies of development and cognitive functioning in healthy children and adolescents. The final sections of this article address the potential application of MRS in identifying neurochemical predictors and consequences of alcohol use and abuse in adolescence. MRS studies of adolescent populations hold promise for advancing our understanding of neurobiological risk factors for psychopathology by identifying the biochemical signatures associated with healthy brain development, as well as neurobiological and cognitive correlates of alcohol and substance use and abuse.
