Adsorption of Organic Pollutants on Carbonaceous Adsorbents Prepared by Direct Activation of Sweet Cherry Stones.

The main objective of this study was to assess the usefulness of the sweet cherry stones for the production of carbonaceous adsorbents by means of direct physical activation method, using conventional and microwave variant of heating. The adsorbents were characterized in terms of textural parameters, acidic-basic character of the surface, electrokinetic properties and their suitability for drinking water purification. Adsorption tests were carried out against three organic compounds - Triton X-100 (surfactant), bovine serum albumin (protein) and methylene blue (synthetic dye).

The Interplay of Conjugation and Metal Coordination in Tuning the Electron Transfer Abilities of NTA-Graphene Based Interfaces.

An artificial leaf is a concept that not only replicates the processes taking place during natural photosynthesis but also provides a source of clean, renewable energy. One important part of such a device are molecules that stabilize the connection between the bioactive side and the electrode, as well as tune the electron transfer between them. In particular, nitrilotriacetic acid (NTA) derivatives used to form a self-assembly monolayer chemisorbed on a graphene monolayer can be seen as a prototypical interface that can be tuned to optimize the electron transfer.

Benefits of time-resolved nonuniform sampling in reaction monitoring: The case of aza-Michael addition of benzylamine and acrylamide.

Monitoring of chemical reactions is best carried out using methods that sample the test object at a rate greater than the time scale of the processes taking place. The recently proposed time-resolved nonuniform sampling (TR-NUS) method allows the use of two-dimensional (2D) nuclear magnetic resonance (NMR) spectra for this purpose and provides a time resolution equivalent to that achievable using one-dimensional spectra. Herein, we show that TR-NUS acquired data eliminates 2D spectral line disturbances and enables more accurate signal integration and kinetics conclusions.

A Call to Restore Your Calling: Self-care of the Emergency Physician in the Face of Life-Changing Stress: Part 6 of 6: Trainee Burnout.

Whereas our last article focused on burnout in practicing pediatric emergency medicine (PEM) physicians, this article centers on burnout in PEM fellows. Our discussion is based solely on trainee burnout literature. As graduates of pediatrics or emergency medicine residencies, PEM fellows are charged with achieving attending-level clinical expertise while continuing to cope with trainee challenges, such as limited practice autonomy, low pay, financial debt, and uncertain future employment.

Accelerated acquisition in pure-shift spectra based on prior knowledge from H NMR.

Pure-shift NMR enhances spectral resolution, but the optimal resolution can only be obtained at the cost of acquisition time. We propose to accelerate pure-shift acquisition using optimised 'burst' non-uniform sampling schemes [I. E.

Qualitative Evaluation of Individual and Group Well-Child Care.

Objective: Individual well care (IWC) is the standard delivery model for well-child care in the United States. Alternative models, such as group well care (GWC), may create opportunities to enhance care for babies. The purpose of this study was to evaluate parents' perceptions of social/wellness benefits and system challenges of IWC and GWC.
