Thermal characteristics of fire extinguishing agents in compartment fire suppression.

Water and foam have different fire-extinguishing mechanisms. Traditional foam and compressed air foam (CAF) have different bubble structures. These differences result in different thermal characteristics, which affect the extinguishing abilities during a fire.

Enhancing Bifunctional Electrocatalytic Activities of Oxygen Electrodes via Incorporating Highly Conductive Sm and Nd Double-Doped Ceria for Reversible Solid Oxide Cells.

Solid oxide cells (SOCs) are mutually convertible energy devices capable of generating electricity from chemical fuels including hydrogen in the fuel cell mode and producing green hydrogen using electricity from renewable but intermittent solar and wind resources in the electrolysis cell mode. An effective approach to enhance the performance of SOCs at reduced temperatures is by developing highly active oxygen electrodes for both oxygen reduction and oxygen evolution reactions. Herein, highly conductive Sm and Nd double-doped ceria (SmNdCeO, SNDC) is utilized as an active component for reversible SOC applications.

Correlation of Time-Dependent Oxygen Surface Exchange Kinetics with Surface Chemistry of LaSrCoFeO Catalysts.

The Sr segregation at the surface of a perovskite LaSrCoFeO (LSCF) oxygen electrode is detrimental to the electrochemical performance and durability of energy conversion devices such as solid oxide fuel cells. However, a quantitative correlation of degradation of the oxygen surface exchange kinetics with Sr precipitation formation at the LSCF surface is not clearly understood yet. Herein, the correlation of the time-dependent degradation mechanisms of the LSCF catalysts with respect to Sr segregation phenomenon at the surface were investigated at 800 °C for a prolonged annealing time (∼800 h) by combining in situ electrochemical measurements, and ex situ chemical and structural analyses at the multiscale.

Functionally Graded Bismuth Oxide/Zirconia Bilayer Electrolytes for High-Performance Intermediate-Temperature Solid Oxide Fuel Cells (IT-SOFCs).

A functionally graded BiErO (ESB)/YZrO (YSZ) bilayer electrolyte is successfully developed via a cost-effective screen printing process using nanoscale ESB powders on the tape-cast NiO-YSZ anode support. Because of the highly enhanced oxygen incorporation process at the cathode/electrolyte interface, a novel bilayer solid oxide fuel cell (SOFC) yields extremely high power density of ∼2.1 W cm at 700 °C, which is a 2.

Comparative in vitro release and clinical pharmacokinetics of leuprolide from Luphere 3M Depot, a 3-month release formulation of leuprolide acetate.

A 3-month depot formulation of leuprolide acetate (Luphere 3M Depot) with a mean microsphere diameter of 22.3 μm was prepared aseptically by spray-drying glacial acetic acid solution of the drug and polylactic acid, and lyophilization in a d-mannitol solution. The encapsulation efficiency and loading content of the drug in the Luphere 3M Depot were 94.

Analysis of acamprosate in beagle dog plasma by LC-MS-MS.

A rapid, sensitive, and specific analytical method was developed and validated to quantify acamprosate calcium in beagle dog plasma. The method employs a single plasma protein precipitation, and the analytes are separated by chromatography on an Acquity UPLC HSS T3 column and analyzed by mass spectrometry in the multiple reaction monitoring (MRM) mode. The method has a chromatographic run time of 1.

Development of a music group psychotherapy intervention for the primary prevention of adjustment difficulties in Korean adolescent girls.

Problem: Traditionally, adolescent mental health in Korea has not been a prime focus for educators, health workers, and politicians, yet a majority of sampled adolescents report interpersonal sensitivity (Kim, 2003).

Method: Thirty-five adolescent girls took part in a six-session school-based music group psychotherapy pilot intervention designed to promote relationships and improve self-control skills.

Finding: Participants identified several outcome benefits that may serve as protective factors in their continued social and emotional development.
