Metal-organic framework supported single-site nickel catalysts for butene dimerization
WASHINGTON, Nov. 10 (TNSres) -- The U.S. Department of Energy's Pacific Northwest National Laboratory issued the following abstract of a journal article:

Homotopic sites in a well-controlled environment are not only ideal systems for mechanistic studies, but also allow optimal control of catalytic transformations. Sites having only a single metal cation and sites consisting of metal oxo complexes with few nickel (Ni) cations supported on the nodes of UiO-66 metal-organic framework (Ni-UiO-66) are studied for 1-butene dimerization. Monomeric Ni sites, which bind to the Zr6 node via two Zr-OH(u3) ... Show Full Article

Charge trapping correction and energy performance of the Majorana Demonstrator
WASHINGTON, Nov. 10 (TNSres) -- The U.S. Department of Energy's Pacific Northwest National Laboratory issued the following abstract of a journal article:

P-type point contact (PPC) high-purity germanium detectors are an important technology in astroparticle and nuclear physics due to their superb energy resolution, low noise, and pulse shape discrimination capabilities. Analysis of data from the Majorana Demonstrator, a neutrinoless double-ss decay experiment deploying PPC detectors enriched in 76Ge, has led to several novel improvements in the analysis of PPC signals.

Exploring sustainable electricity system development pathways in South America's MERCOSUR sub-region
WASHINGTON, Nov. 9 (TNSres) -- The U.S. Department of Energy's Pacific Northwest National Laboratory issued the following abstract of a journal article:

South America has abundant natural water and energy resources, and exploiting these resources to achieve a clean energy future is central to the continent's economic and sustainable development objectives for the next several decades. Designing pathways to achieving this clean energy future requires better understanding the structural, techno-economic, and policy forces that may influence the future development of the electricity sector in the ...

baseflow: a MATLAB and GNU Octave package for baseflow recession analysis
WASHINGTON, Nov. 8 (TNSres) -- The U.S. Department of Energy's Pacific Northwest National Laboratory issued the following abstract of a journal article:

`baseflow` is a MATLAB(r) [@matlab_2020_] toolbox that facilitates baseflow recession analysis, a set of methods used in hydrologic science to infer aquifer properties that cannot be measured directly [@brutsaert_1977_WRR].

The widespread availability of streamflow measurements means that baseflow recession analysis can be used to estimate aquifer properties and their variations globally over the modern instrumental stream gage record.

Assessing Multi-Dimensional Impacts of Achieving Sustainability Goals by Projecting the Sustainable Agriculture Matrix into the Future
WASHINGTON, Nov. 8 (TNSres) -- The U.S. Department of Energy's Pacific Northwest National Laboratory issued the following abstract of a journal article:

The concept of sustainability inherently spans multiple spatial scales, sectors, variables, and time horizons. This study links a recently developed method of assessing present-day agricultural sustainability across environmental, economic, and social dimensions with a process-based integrated assessment model, in order to allow forward-looking analysis of sustainability by region and scenario.

The Sustainable Agriculture Matrix (SAM) estimates ... Show Full Article

A Scalable Wave Resource Assessment Methodology: Application to U.S. Waters
WASHINGTON, Nov. 8 (TNSres) -- The U.S. Department of Energy's Pacific Northwest National Laboratory issued the following abstract of a journal article:

Wave energy technology research and development has accelerated over the last two decades. This is largely based on the recognition that waves deliver massive quantities of energy to populated coastlines around the world. Throughout this time, however, there have been ongoing debates about the correct methodology for quantifying the wave energy opportunity. The debate has centered on basic principles of wave energy converter technology, and the ... Show Full Article
