Enhancing Gas Separation Selectivity Prediction through Novel Descriptors

open access: yes, 2023
Adsorption-based techniques for gas separation using nanoporous materials are widely used and hold a promising future, but systematic identification of the best-performing materials for a given application is still an open problem. For that task, we need

Ligand controlled orthogonal selectivity between distal positions of fully unbiased aliphatic amines

open access: yes, 2023
Aliphatic C(sp3)‒H bonds are inherently difficult to activate owing to their inertness and chemical indistinguishability. This challenge has been overcome mostly by directing group approach however the regioselectivity in distal aliphatic positions has ...

Modelling the effects of more selective trawl nets on the productivity of European hake (Merluccius merluccius) and deep-water rose shrimp (Parapenaeus longirostris) stocks in the Strait of Sicily

open access: yesScientia Marina, 2018
Single-species Gadget models were used to assess the effects of using a sorting grid mounted on the traditional trawl net used by Sicilian trawlers to exploit the deep-water rose shrimp in the Strait of Sicily.

Organocatalytic Ring-Opening Polymerization by Fluorinated Alcohol: Fulfilling Cocatalyst-Free, Metal-Free, High-Rate and High-Selectivity

open access: yes, 2019
we describe a fluorinated alcohol based catalytic system for polypeptide synthesis via catalytic ring-opening polymerization (ROP) of α-amino acid N-carboxyanhydride (NCA), fulfilling cocatalyst-free, metal-free, high-rate and high-selectivity.

Estimating the Return to College Selectivity over the Career Using Administrative Earnings Data [PDF]

open access: yes
We estimate the monetary return to attending a highly selective college using the College and Beyond (C&B) Survey linked to Detailed Earnings Records from the Social Security Administration (SSA). This paper extends earlier work by Dale and Krueger (2002)

Glycerol Electrooxidation at Structured Nickel Electrodes and the Effect of Geometry on the Selectivity of Product

open access: yesChemElectroChem
Electrocatalytic selectivity is generally explained in terms of atomic‐scale properties, i.e., active sites, overlooking the impact of macroscopic electrode geometry and structure, which affect the macroscopic mass transport.

Immigrant Health--Selectivity and Acculturation [PDF]

open access: yes
This paper explores some salient issues concerning immigrant health. Ethnic health disparities are inherently linked to immigration since ethnic identities often are traced to the country of origin of one's immigrant ancestors.

Produtos naturais e sintéticos no controle de Leucoptera coffeella (Guérin-Mèneville & Perrottet, 1842) (Lepdoptera: Lyonetiidae) e seus efeitos sobre a predação por vespas Natural and sinthetic products in the control of Leucoptera coffeella (Guérin-Mèneville & Perrottet, 1842) (Lepidoptera: Lyonetiidae) and their effects on predation for wasps

open access: yesCiência e Agrotecnologia, 2006
O controle do bicho-mineiro-do-cafeeiro Leucoptera coffeella (Guérin-Mèneville & Perrottet, 1842) é realizado por meio de inseticidas de amplo espectro de ação, capazes de causar desequilíbrios biológicos, sendo importante a busca por produtos que ...
