The title compound, C(10)H(9)NO(4), was obtained serendipitously during the preparation of benzyl cyclo-hexyl-carbamate. The mol-ecule consists of two approximately planar parts, the nitro-phenyl ring and the rest of the non-H atoms, with a dihedral angle of 55.05 (6)° between the two segments. The crystal structure is stabilized by weak C-H⋯O inter-actions and π stacking [3.753 (1) Å] along th...
We conducted a prospective study in order to audit our experience of repairing cranial defects using Methyl methacrylate. This included a total of 49 patients undergoing cranioplasty using methyl methacrylate, of which 45 were males and 4 females. The age of patients at the time of surgery ranged from 16 to 40 years old, with an average of 24 years. Malays were the majority (67%), followed by C...
Waterborne isocyanate-free grafted poly(hydroxy urethane)-poly(butyl methacrylate) hybrid dispersions were synthesized by miniemulsion polymerization. Grafting was induced including methacrylate functionalities in the urethane) and controlled degree of functionalization. It is shown that grafting enabled a fine tuning mechanical properties PHU containing hybrids.
objectives: composite restorations must have tooth-like optical properties namely color and translucency and maintain them for a long time. this study aimed to compare the effect of accelerated artificial aging (aaa) on the translucency of three methacrylate-based composites (filtek z250, filtek z250xt and filtek z350xt) and one silorane-based composite resin (filtek p90). materials and methods...
this research was conducted to study the effects of styrene and methyl methacrylate cell lumen monomers on the mechanical properties and decay resistance of beech wood. mechanical and decay resistance test samples were prepared according to astm d143-94 and din en113 standards and impregnated with five concentration monomer solution 0, 40, 60, 80 and 100 percent using bethell method. treated sa...
Borysko and Sapranauskas (1) and independently Gay (2) have described a method of making coverslip preparations of biological material from which small selected cell groups or single cells may be transferred to methacrylate for sectioning for electron microscopy. In both procedures it is suggested that the selected material viewed under light and phase microscopy be covered with a capsule conta...
Imitating the natural "energy cascade" architecture, we present a single-molecular rod-like nano-light harvester (NLH) based on a cylindrical polymer brush. Block copolymer side chains carrying (9,9-diethylfluoren-2-yl)methyl methacrylate units as light absorbing antennae (energy donors) are tethered to a linear polymer backbone containing 9-anthracenemethyl methacrylate units as emitting group...
