The Influence of Solid Heat Carrier Load of Char on Pyrolysis Characteristics of Pulverized Coal in a Fluidized Bed Reactor

Energies
Pulverized coal pyrolysis based on solid heat carrier has a huge advantage in high tar yield. In this study, pyrolysis experiments on pulverized coal were conducted in a lab-scale fluidized bed reactor at 650 °C, utilizing char as the solid heat carrier.

Eye makeup in Northwestern Iran at the time of the Assyrian Empire: a new kohl recipe based on manganese and graphite from Kani Koter (Iron Age III)

Archaeometry, EarlyView.
Abstract Kohl was ubiquitous in ancient Egypt and the Middle East, and routinely included among the toiletries deposited in burials. For Egypt, kohl recipes are increasingly well‐studied and known to use a range of inorganic and organic ingredients. Although these are often lead‐based, manganese‐ and silicon‐rich compounds are also attested.

Influence of low-density polyethylene addition on coking pressure [PDF]

, 2014
Different amounts of low-density polyethylene (LDPE) were added to a bituminous coal used to produce metallurgical coke. The effect of the plastic waste on the carbonization process and more exactly, on the coking pressure were investigated.

The Oldest Traces of Alcoholic Beverages in the Border Zone of the North and East European Plains

Archaeometry, EarlyView.
ABSTRACT Analysis of organic compounds preserved on pottery from the Bell Beaker community and the initial phase of the Trzciniec Cultural Sphere in the border zone of the Eastern and North European Plains was prompted by traces of alcoholic beverages found in contextually and formally analogous discoveries of more westerly provenance.

In‐vivo pilot study to assess a new plant‐based cosmetic formulation containing Ziziphus joazeiro bark extract and Apium graveolens seed extract for the improvement of dandruff while enhancing scalp microbiome balance and barrier function in subjects with oily to dry sensitive scalps

International Journal of Cosmetic Science, EarlyView.
This study comprising dermatological as well as microbiome analysis indicates that mild‐to‐moderate dandruff symptoms can successfully be reduced with a plant‐based shampoo by restoring the bacterial scalp microbiome balance, suggesting a ‘microbiome‐friendly’ formulation tolerated excellently for oily scalp and sensitive scalp.
