Nature Communications, 2019 AbstractClimate change represents an existential, global threat to humanity, yet its delocalized nature complicates climate action. Here, the authors propose retrofitting air conditioning units as integrated, scalable, and renewable-powered devices capable of decentralized CO2 conversion and energy democratization.

Journal of Economics and Business, 2021 This paper investigates the impacts of a large and exogenous oil price shock in December 1973 on mortality rates of the major oil producer nations of the Middle East and North Africa. We use longitudinal data from 1960 to 2014 and we apply the difference-in-differences approach to investigate the main question of the research.

Clinical heterogeneity in a family with flail arm syndrome and review of hnRNPA1‐related spectrum
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1910-1917, December 2022., 2022 Abstract Objective Flail arm syndrome (FAS) is one of the atypical subtypes of amyotrophic lateral sclerosis (ALS). Mutations in hnRNPA1 encoding heterogeneous nuclear ribonucleoprotein (hnRNP) A1 are a rare genetic cause of ALS. Herein, marked clinical heterogeneity of FAS in a pedigree with a known hnRNPA1 variant was described to raise early ...

Architected Lattices with a Topological Transition
Advanced Engineering Materials, EarlyView., 2023 This article develops topological metamaterials showing multidirectional two‐step deformation under compression by embedding contact‐enabled topological mechanisms into lattice structures. Experiments on 3D‐printed 2D and 3D lattices and finite element simulations are conducted to demonstrate the working principle of the topological metamaterials.

Particles at Oil–Air Surfaces: Powdered Oil, Liquid Oil Marbles, and Oil Foam [PDF]
ACS Applied Materials & Interfaces, 2015 The type of material stabilized by four kinds of fluorinated particles (sericite and bentonite platelet clays and spherical zinc oxide) in air-oil mixtures has been investigated. It depends on the particle wettability and the degree of shear. Upon vigorous agitation, oil dispersions are formed in all the oils containing relatively large bentonite ...

Antioxidant effect of an ozonized theobroma oil formulation on damaged-inflammatory rat skin
Grasas y Aceites, 2011 The aim of this study was to determine whether a cosmetic formulation elaborated with ozonized theobroma oil may exert beneficial effects in the restoring of the antioxidant activity on the skin of rats previously irradiated with ultraviolet light. 0.5 g

Influence of Sequential Changes in the Crude Oil-Water Interfacial Tension on Spontaneous Imbibition in Oil-Wet Sandstone [PDF]
, 2021 Crude oil-water interfacial tension in petroleum reservoir is reduced or increased due to surfactant injection or surfactant retention, respectively. Changes in the interfacial tension crucially attribute to a governing capillary pressure and hence an oil displacement in spontaneous imbibition process.

Thermal stability of some metal-palmitate soaps which find various industrial applications
Grasas y Aceites, 2001 The soaps of alkaline earth's and transition elements and closed ‘d’ orbitals were prepared by the double decomposition method by the reaction between metallic salts and sodium palmitate. The thermal stability of these soaps was studied in order to throw

Pattern recognition based on machine learning identifies oil adulteration and edible oil mixtures
Nature Communications, 2020 Fraudulent adulteration of edible oils is based on the fact that their characteristic fatty acid profile can be mimicked with mixtures of other oil types.
