Fibrous Filler as an Extender for Titanium Dioxide – Methods of Filler Addition

The paper industry today faces higher costs in such fillers as titanium dioxide. The need for extenders to add to the pulp slurries with titanium dioxide is ever increasing. The extender must not lower the strength properties of the paper to any large extent and must yield nearly the same optical properties as titanium dioxide. Fibrous filler has proven to be a filler which meets these requirements. There exists, however, several different methods for the addition of the fillers to the pulp stock. Each of these methods give different results in the final sheet of paper. It was found from this project the adding titanium dioxide first or while precipitating out the fibrous filler with the total amount of pulp gave the highest optical properties. This is because of one of two reasons. Fibrous filler, while precipitating, increases the retention of the other fillers present. The other reason is that when titanium dioxide is present along with the fibers while fibrous filler is precipitating, something happens in the filler orientation which causes a difference in the way the light rays are scattered in the paper. Fibrous filler when used as an extender can therefore be used to partially eliminate some of the titanium dioxide at a cost savings

Outcomes of Adding Patient and Family Engagement Education to Fall Prevention Bundled Interventions.

Nurses strive to reduce risk and ensure patient safety from falls in health care systems. Patients and their families are able to take a more active role in reducing falls. The focus of this article is on the use of bundled fall prevention interventions highlighted by a patient/family engagement educational video. The implementation of this quality improvement intervention across 2 different patient populations was successful in achieving unit benchmarks

Time-resolved impulse response of the magnetoplasmon resonance in a two-dimensional electron gas

We have used optically excited ultrashort electrical pulses to measure the magnetoplasmon resonance of a two-dimensional electron gas formed in an AlGaAs/GaAs heterostructure at frequencies up to 200 gigahertz. This is accomplished by incorporating the sample into a guided wave probe operating in a pumped (^{3}He) system. We are able to detect the resonance by launching a stimulus pulse in the guide, and monitoring the system response in a time resolved pump-probe arrangement. Data obtained from measurements yield resonant frequencies that agree with the magnetoplasmon dispersion relation.Comment: 4 pages, 4 figure

X-ray diffraction measurements of Mo melting to 119 GPa and the high pressure phase diagram

In this paper, we report angle-dispersive X-ray diffraction data of molybdenum melting, measured in a double-sided laser-heated diamond-anvil cell up to a pressure of 119 GPa and temperatures up to 3400 K. The new melting temperatures are in excellent agreement with earlier measurements up to 90 GPa that relied on optical observations of melting and in strong contrast to most theoretical estimates. The X-ray measurements show that the solid melts from the bcc structure throughout the reported pressure range and provide no evidence for a high temperature transition from bcc to a close-packed structure, or to any other crystalline structure. This observation contradicts earlier interpretations of shock data arguing for such a transition. Instead, the values for the Poisson ratios of shock compressed Mo, obtained from the sound speed measurements, and the present X-ray evidence of loss of long-range order suggest that the 210 GPa ( ∼ 4100 K) transition in the shock experiment is from the bcc structure to a new, highly viscous, structured [email protected]

Skin stimulation and recording: Moving towards metal-free electrodes

When one thinks about electrodes, especially ones meant for humans, one typically thinks of some kind of metal. Whether on the skin or in the brain, metal electrodes are characteristically expensive, stiff, non-efficient in electron-ion transduction, and prone to toxic metal ion by-products during stimulation. In order to circumvent these disadvantages, electrically-conductive laser-induced graphene (LIG) and mixed electron-ion conducting polymer (poly(3, 4‐ethylenedioxythiophene) polystyrene sulfonate – PEDOT:PSS) was leveraged to create a metal-free electrode combination that allows for an economical, soft, and organic electrode for applications on human skin. Compared to clinical-standard silver – silver chloride (Ag/AgCl) skin electrodes, the metal-free hydrogel electrodes show notable improvement in electrochemical stability and prolonged stable potentials during long-term DC stimulation (0.5–24 h). Recording and stimulation performance on human participants rivals that of Ag/AgCl, thus fortifying the notion that they are an appropriate progression to their noble metal counterparts
