Enhanced Resolution of Poly-(Methyl Methacrylate) Electron Resist by Thermal Processing [PDF]
J. Vac. Sci. Technol. B 27,4, pp. 1915-1918, 2009, 2012 Granular nanostructure of electron beam resist had limited the ultimate resolution of electron beam lithography. We report a thermal process to achieve a uniform and homogeneous amorphous thin film of poly methyl methacrylate electron resist. This thermal process consists of a short time-high temperature backing process in addition to precisely ...

FMO Study of the Interaction Energy between Human Estrogen Receptor $α$ and Selected Ligands [PDF]
arXiv, 2022 Fragment molecular orbital (FMO) calculations were performed in aqueous media which allowed us to obtain the interaction energy between the human estrogen receptor $\alpha$ ligand-binding domain (ER) and the selected ligands (L): 17$\beta$-estradiol (E2), 17$\alpha$-estradiol (17$\alpha$-E2), estriol (E3), genistein (GNT), diethylstilbestrol (DES ...

Patchy worm-like micelles: solution structure studied by small-angle neutron scattering [PDF]
Phys. Chem. Chem. Phys. 14, 12750 (2012), 2012 Triblock terpolymers exhibit a rich self-organization behavior including the formation of fascinating cylindrical core-shell structures with a phase separated corona. After crystallization-induced self-assembly of polystryrene-(block)-polyethylene-(block)-poly(methyl methacrylate) triblock terpolymers (abbreviated as SEMs = Styrene-Ethylene ...

Bisgma stimulates prostaglandin E2 production in macrophages via cyclooxygenase-2, cytosolic phospholipase A2, and mitogen-activated protein kinases family. [PDF]
PLoS ONE, 2013 BACKGROUND: Bisphenol A-glycidyl-methacrylate (BisGMA) employs as a monomer in dental resins. The leakage of BisGMA from composite resins into the peripheral environment can result in inflammation via macrophage activation.

Molecular simulation of thermosetting polymer hardening: reactive events enabled by controlled topology transfer [PDF]
, 2020 We present a quantum mechanical / molecular mechanics (QM/MM) to tackle chemical reactions with substantial molecular reorganization. For this, molecular dynamics simulations with smoothly switched interaction models are used to suggest suitable product states, whilst a Monte Carlo algorithm is employed to assess the reaction likeliness subject to ...

A Prospective Cohort Study of Bisphenol A Exposure from Dental Treatment
Journal of dentistry research, 2020 Laboratory studies show that bisphenol A (BPA) leaches from bisphenol A-glycidyl methacrylate (bisGMA)-based dental materials. We aimed to quantify the extent to which children are exposed to BPA from dental treatment with bisGMA materials, by amount of ...

Mineral deposition promoted by resin-based sealants with different calcium phosphate additions [PDF]
Brazilian Oral Research, 2019 The aim of this study was to evaluate the influence of different calcium phosphates (CaPs) on the physical, biological, and remineralizing properties of experimental resin-based sealants (RBSs).
