Sustainable decision making for chemical process systems via dimensionality reduction of many objective problems

open access: yesAIChE Journal, Volume 69, Issue 2, February 2023., 2023
Abstract Recent global events and the rise of sustainable investing have made clear that the chemical and energy industry must consider sustainability goals beyond profit maximization to remain competitive. Multiobjective optimization provides an ideal framework for analyzing sustainability tradeoffs, but when four or more objectives are considered ...

MICROBIAL DIVERSITY AND THE MODERN APPROACH TO THE INVESTIGATION OF COMPLEX MICROBIAL ECOSYSTEMS

open access: yesActa Agriculturae Slovenica, 1998
Our knowledge about microbial diversity has been rapidly accumulating due to the application of the modern molecular biology based techniques. DNA sequence based taxonomy and phylogenetic studies were among the first that implemented molecular biology ...

Peculiar Orbital Characteristics of Earth Quasi-Satellite 469219 Kamo‘oalewa: Implications for the Yarkovsky Detection and Orbital Uncertainty Propagation

open access: yesThe Astronomical Journal, 2023
469219 Kamo‘oalewa is selected as one of the primary targets of Tianwen-2 mission, which is currently believed to be the most stable quasi-satellite of Earth. Here we derive a weak detection of the Yarkovsky effect for Kamo‘oalewa, giving A _2 = (−1.075 ±

Finding Asteroids Down the Back of the Couch: A Novel Approach to the Minor Planet Linking Problem [PDF]

open access: yesarXiv, 2018
We present a novel approach to the minor planet linking problem. Our heliocentric transformation-and-propagation algorithm clusters tracklets at common epochs, allowing for the efficient identification of tracklets that represent the same minor planet.

Tuning Transition Metal 3d Spin state on Single‐atom Catalysts for Selective Electrochemical CO2 Reduction

open access: yesAdvanced Materials, EarlyView.
The introduction of P into a single‐atom Fe catalyst is shown to induce a shift in its electronic configuration toward a high spin state. This is proposed to enhance electron back donation via the dxz/dyz‐π* bond, which improves *COOH adsorption and facilitates the electrochemical conversion of CO2 to CO.

MINOR PLANET 2008 ED69 AND THE KAPPA CYGNID METEOR SHOWER

open access: yes, 2008
Until recently, the kappa Cygnids (IAU#12) were considered an old shower, because the meteors were significantly dispersed in node, radiant, and speed, despite being 28–38° inclined.

DIVISION III / SERVICE MINOR PLANET CENTER

open access: yesProceedings of the International Astronomical Union, 2008
The activity of the Minor Planet Center continued generally to increase during the triennium. This report covers the period 2008 July 1 to 2011 October 12, and the phrase “during the triennium” in this report should be understood to mean this period.

Kinetically Dormant Ni‐Rich Layered Cathode During High‐Voltage Operation

open access: yesAdvanced Materials, EarlyView.
Ni‐rich layered cathode remains thermodynamically reversible but undergoes dramatic kinetic degradation at high voltage, leading to the commonly observed capacity loss that in fact can be recovered under kinetic‐free conditions. Such kinetic dormant behavior highly synchronizes with the lattice strain evolution stemming from layered/rock‐salt ...

Rotation period of the minor planet 2010 WC9 [PDF]

open access: yesarXiv, 2018
Photometric observations of the minor planet 2010 WC9 carried out by one of us (Diepvens) in May 14$^{th}$, 2018 have allowed obtain a lightcurve of around 110 minutes and determine the rotation period of this asteroid.
