A comparative DFT study of HCHO decomposition on different terminations of the CoO(110) surface.

Density functional theory calculations have been performed to compare the HCHO decomposition on CoO(110)-A and (110)-B terminations. The results showed that the energy barriers of the two C-H bond cleavages of HCHO on the (110)-A termination were lower than those on the (110)-B termination, suggesting that the (110)-A termination had stronger HCHO decomposition ability than the (110)-B termination. Electronic structures revealed that the stronger HCHO decomposition ability of the (110)-A termination might be ascribed to the strong covalent bond between HCHO and the (110)-A termination, as well as the higher d-band center of Co ions on the (110)-A termination.

Synthesis of Bio-Active Silver Nanoparticles against Human Lung Cancer Cell Line (A549) with Little Toxicity to Normal Cell Line (WRL68).

Nanomaterials are characterized by mechanical, thermal, chemical, biological, and other properties that are different from the basic materials that make them up due to their large surface area to size ratio and quantum effect. There are multiple ways to produce nanomaterials mechanically, chemically, and physically, but they are not safe for the environment. Researchers have sought to find safe methods for the production of nanomaterials, such as green manufacturing, that is, manufacturing nanomaterials from plants.

Acute and chronic glutamate NMDA antagonist treatment attenuates dopamine D antagonist-induced reduction of nicotine self-administration in female rats.

Multiple interacting neural systems are involved in sustaining nicotine reinforcement. We and others have shown that dopamine D receptors and glutamate NMDA receptors both play important roles in nicotine reinforcement. Blockade of D receptors with the antagonist SCH-23390 (0.

Self-administration by female rats of low doses of nicotine alone vs. nicotine in tobacco smoke extract.

Background: Nicotine has reinforcing effects, but there are thousands of other compounds in tobacco, some of which might interact with nicotine reinforcement.

Aims: This rat study was conducted to determine if nicotine self-administration is altered by co-administration of the complex mixture of compounds in tobacco smoke extract (TSE).

Methods: Female Sprague-Dawley rats were tested for self-administration of low doses of nicotine (3 or 10 µg/kg/infusion) at three different rates of reinforcement (FR1, FR3 and FR5) over three weeks either alone or together with the complex mixture of tobacco smoke extract (TSE).

Patient satisfaction with the emergency department services at an academic teaching hospital.

Introduction: Healthcare reform efforts focus on patient-centered care is measured by patient satisfaction. Emergency department (ED) satisfaction ratings are often the lowest. Since ED is the first point of contact for the patient care to receive primary care, we aimed to explore patient satisfaction related to ED healthcare services at our institution.
