Analog simulator of integro-differential equations with classical memristors
(Nature Publishing, 2019-09-10)
An analog computer makes use of continuously changeable quantities of a system, such as its electrical, mechanical, or hydraulic properties, to solve a given problem. While these devices are usually computationally more ...
Cost-effective upgrading of biomass pyrolysis oil using activated dolomite as a basic catalyst
(Elsevier B.V., 2019-07-19)
This study deals with a continuous process on a calcined dolomite operating at atmospheric pressure and by cofeeding
water for cost-effective upgrading of raw bio-oil at 400 °C and 500 °C. The distribution of carbon in ...
A CRITICAL REVIEW of COST-BENEFIT ANALYSIS for CLIMATE CHANGE ADAPTATION in CITIES
(Climate Change Economics, 2019-11-01)
his study systematically reviews the scientific literature (n=56) on cost-benefit analysis (CBA) of adaptation measures in cities and similar urban environments. The review is conducted to assess existing or proposed actions ...
Comparative analysis of the socio-economic characteristics of Delta and Non-Delta spaces of Ghana: An input-output approach
(African Review of Economics and Finance, 2019-07-08)
This paper provides insights into the current socioeconomic and biophysical state of
the Volta Delta, Ghana. We employed non-survey methods, notably the Flegg Location
Quotient (FLQ) method of regionalization and ...
Serum Metabolites as Diagnostic Biomarkers for Cholangiocarcinoma, Hepatocellular Carcinoma, and Primary Sclerosing Cholangitis
(Wiley, 2019-08)
Early and differential diagnosis of intrahepatic cholangiocarcinoma (iCCA) and hepatocellular carcinoma (HCC) by noninvasive methods represents a current clinical challenge. The analysis of low-molecular-weight metabolites ...
Effect of Chemical Structure and Salt Concentration on the Crystallization and Ionic Conductivity of Aliphatic Polyethers
(MDPI, 2019-03-09)
Poly(ethylene oxide) (PEO) is the most widely used polymer in the field of solid polymer electrolytes for batteries. It is well known that the crystallinity of polymer electrolytes strongly affects the ionic conductivity ...
CO2-sourced polycarbonates as solid electrolytes for room temperature operating lithium batteries
(Royal Society of Chemistry, 2019-03-19)
In the last few years, polycarbonates have been identified as alternatives to poly(ethylene oxide) as polymer electrolytes for lithium battery applications. In this work, we show the design of CO2-sourced
polycarbonates ...
Opportunities for organocatalysis in polymer synthesis via step-growth methods
(Elservier, 2019-03-14)
Organocatalysis has emerged as an invaluable tool for polymer synthesis and has already demonstrated versatility for replacing organometallic catalysts in many polymerization reactions. The overall ease of removal and lower ...
Maternal circulating Vitamin D-3 levels during pregnancy and behaviour across childhood
(Nature Publishing Group, 2019-10-15)
Vitamin D deficiency during critical periods of development could lead to persistent brain alterations. We aimed to assess the association between maternal vitamin D-3, the major circulatory form of vitamin D, at pregnancy ...
ROP and crystallization behaviour of partially renewable triblock aromaticaliphatic copolymers derived from L-lactide
(Elsevier, 2019-10-26)
Two series of partially biobased ABA triblock copolyesters were successfully prepared by ring-opening polymerization (ROP) of L-lactide initiated by two telechelic polyester polyols using an organic catalyst. B blocks were ...
