Nutrition Status of Trees on Spoil Heaps After Coal Mining Can Be Inferred From Seasonal Dynamics of Foliar Nutrient Concentrations

Land Degradation &Development, EarlyView.
ABSTRACT A stable vegetation cover on given habitat conditions can be one of the possible requirements for post‐mining sites, as it can prevent erosion and dustiness of these anthropogenic surfaces and bring several practical future benefits, such as biomass production and microclimate improvement.

Efeito do tempo de exposição a uma atmosfera coqueificante na microestrutura e nas propriedades de um concreto refratário usado na indústria petroquímica Effect of the exposure time in cokemaking atmosphere on the microstructure and properties of a refractory castable used in the petrochemical industry

Cerâmica, 2012
Os concretos refratários usados em unidades de craqueamento catalítico fluidizado (UFCC) podem sofrer deterioração pela deposição de coque durante o processo de produção de hidrocarbonetos leves, ocasionando a diminuição do tempo de funcionamento do ...

Influência dos aditivos de consolidação sobre as propriedades termomecânicas da matriz de concretos de projeção Influence of setting additives on the thermomechanical properties of wet shotcrete refractory castables' matrix

Cerâmica, 2004
A projeção a úmido de concretos refratários consiste na aplicação do material na forma de um jato de "spray" sobre uma superfície, resultando numa elevada taxa de instalação e eficiente compactação do material.

A Mini Review on Evolution of High‐Entropy Alloy Design: From Experimental Approaches to Machine Learning Integration

Rare Metals, EarlyView.
ABSTRACT High‐entropy alloys (HEAs) have emerged as a transformative class of materials distinguished by their complex chemical compositions, unique microstructures, and remarkable mechanical and functional properties. Traditionally, the discovery and optimization of HEAs have relied on conventional methods, including trial‐and‐error experimentation ...
