Simultaneous upgrading of tar sand bitumen and coal by corefining

open access: yes, 1988
patentAn improved tar sands derived bitumen and coal liquification process is disclosed wherein substantial percentages of subdivided coal particles and tar sands derived bitumen liquids are mixed and then corefined with hydrogen under hydrocracking ...

Coal-tar pitch as the matrix carbon precursor in carbon–carbon composites

open access: yes, 1995
Coal-tar pitch is a promising carbon matrix precursor for carbon-carbon composites. It has a suitable viscosity, high carbon yield, and it forms graphitic structures. In addition, pitch is a relatively cheap raw material.

An Effective Approach for Separating Carbazole and Its Derivates from Coal-Tar-Derived Anthracene Oil Using Ionic Liquids

open access: yes, 2018
Carbazole and its derivates are important value-added chemicals (VACs) in anthracene oil (AO), which is one of the coal tar fractions. In this work, imidazolium-based ionic liquids (ILs) were used as novel extractants to extract carbazole from AO and the

Associations of Outdoor Air Pollution With Incidence of Cancers Other Than Lung Cancer in a Large US Prospective Cohort

open access: yesInternational Journal of Cancer, EarlyView.
Associations between outdoor air pollution and cancers other than lung cancer remain unclear, particularly in the context of tobacco use. Here, the authors assessed possible links between ambient air pollutant exposure and incidence of 20 non‐lung cancers among adults followed over a 25‐year period in the United States.

Exploring the Chemical Complexity and Toxicological Behaviour of Semi‐permanent Make‐Up Pigments: A Systematic Review

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Semi‐permanent make‐up (SPMU), or micropigmentation, involves implanting pigments into the dermal layer of the skin for cosmetic enhancement. Unlike topical cosmetics, which are rapidly cleared from the body, SPMU pigments persist in living tissues, raising unique toxicological considerations.

Chronic Hand Eczema of Charlie Chaplin

open access: yesJEADV Clinical Practice, EarlyView.
Abstract Charlie Chaplin (1889–1977), one of the most iconic figures in cinema history, suffered throughout his career from a chronic hand eczema he consistently concealed behind white cotton gloves. According to his biographers, Chaplin attributed this condition to the prolonged handling of cellulose nitrate film stock during editing—a highly ...

Modeling the Thermal Properties of Hydrogen‐Based Direct Reduced Iron Using Computational Thermodynamics and Machine Learning

open access: yessteel research international, EarlyView.
Hydrogen‐based direct reduced iron (H‐DRI) melts differently from scrap and carbon‐bearing DRI. This work combines differential scanning calorimetry experiments, FactSage thermodynamics, and simple composition‐based regression to predict solidus, liquidus, heat capacity, and enthalpy for H‐DRI.

COAL-TAR IN CHRONIC ECZEMA. [PDF]

open access: yesJournal of the American Medical Association, 1908
I desire to call attention to the value and efficiency of common coal-tar in the treatment of certain types of eczema. This substance, a dark, thick, semi-liquid, is obtained as a product of the dry distillation of bituminous coal and contains a number of active chemicals, carbolic acid and creosote being among the most important.
