TL;DR: FTIR and 13C NMR spectroscopy indicate that the epoxides polymerize to form a polyether cap on the surfaces of the aluminum nanoparticles, which reveals that 96% of the total aluminum present is active (unoxidized) aluminum.
Abstract: We report here on the synthesis and passivation of small (20-30 nm) aluminum nanoparticles using alkyl-substituted epoxides as capping agents. FTIR and 13C NMR spectroscopy indicate that the epoxides polymerize to form a polyether cap on the surfaces of the aluminum nanoparticles. Nanoparticles capped with epoxyhexane and epoxydodecane are stable in air, but particles capped with epoxyisobutane are pyrophoric. TEM images show spherical Al particles. Powder X-ray diffraction shows the presence of crystalline Al. Titrimetric analysis of the core-shell nanostructures in air reveals that 96% of the total aluminum present is active (unoxidized) aluminum.

TL;DR: For the given simulated tasks in the laboratory setting, the better scores for the upper extremity postural analysis indicate that telerobotic surgery provides a more comfortable environment for the surgeon without any additional mental stress.
Abstract: Background Minimally invasive surgical techniques expose surgeons to a variety of occupational hazards that may promote musculoskeletal disorders. Telerobotic systems for minimally invasive surgery may help to reduce these stressors. The objective of this study was to compare manual and telerobotic endoscopic surgery in terms of postural and mental stress.

TL;DR: Here a methodology is reported to obtain near 100% refl ectivity in a single CLC fi lm (so called hyper-refl ectivity) in which surface-bound polymer stabilization is used to spatially segregate disparate regions of opposite handedness in asingle cell through the use of a thermally tunable CLC mixture.
Abstract: where n s and n o are the extraordinary and ordinary refractive indices, respectively. The maximum refl ection of unpolarized light is 50% because a planar aligned cell only refl ects circularly polarized light of the same handedness as the helical pitch. Methodologies to overcome this limitation include the stacking of two opposite-handed CLC fi lms or stacking two same-handed CLC fi lms separated by a half waveplate. [ 1–8 ] Here a methodology is reported to obtain near 100% refl ectivity in a single CLC fi lm (so called hyper-refl ectivity) in which surface-bound polymer stabilization is used to spatially segregate disparate regions of opposite handedness in a single cell. Through the use of a thermally tunable CLC mixture, the high contrast condition can be induced with temperature. The versatility of the approach is further demonstrated by creating a cell with two static refl ection notches at different wavelengths and thermally inducing high contrast at each notch by varying the temperature. High-contrast, selectively refl ecting materials have a variety of prospective applications in displays and photonics, allowing for on/off control of a portion of the spectrum while passing all other wavelengths. A simple method to attain high contrast refl ectors has utilized chiral polymeric materials mixed with opposite-handed CLC mixtures to yield hyper-refl ective CLCs (defi ned here as single-cell CLCs with a refl ection greater

TL;DR: A physiologically based model for diisopropylfluorophosphate (DFP) pharmacokinetics and acetylcholinesterase (AChE) inhibition was developed in mammals and demonstrated the possibility of using a model based on mammalian physiology and biochemistry to simulate in vivo data on DFP pharmacokinetic and AChE inhibition.

TL;DR: An overview of the model-based measures of SFT is provided, together with a tutorial on designing a DFP experiment to take advantage of all SFT measures in a single experiment and a new package for performing SFT analyses using R for statistical computing is introduced.
Abstract: Systems factorial technology (SFT) comprises a set of powerful nonparametric models and measures, together with a theory-driven experiment methodology termed the double factorial paradigm (DFP), for assessing the cognitive information-processing mechanisms supporting the processing of multiple sources of information in a given task (Townsend and Nozawa, Journal of Mathematical Psychology 39:321–360, 1995). We provide an overview of the model-based measures of SFT, together with a tutorial on designing a DFP experiment to take advantage of all SFT measures in a single experiment. Illustrative examples are given to highlight the breadth of applicability of these techniques across psychology. We further introduce and demonstrate a new package for performing SFT analyses using R for statistical computing.
