Effective Removal of Fe and Ca From Coal Fly Ash for High-Purity and High-Surface-Area Zeolite X Synthesis: A Comparative Study of Acid Refluxing and Acid Roasting Methods. [PDF]

open access: yesChemistryOpen
Coal fly ash (CFA) is an abundant industrial waste rich in silica and alumina and represents a viable feedstock for zeolite synthesis; however, high levels of calcium and iron limit zeolite purity and crystallisation. This study evaluates acid refluxing and acid roasting as pre‐treatment strategies for the simultaneous removal of Ca and Fe from high ...

Neuromorphic Near‐Sensor and In‐Sensor Computing Enabled by Next‐Generation Material‐Based Sensors

open access: yesAdvanced Science, EarlyView.
This Review presents a structural framework that classifies neuromorphic sensing into near‐sensor and in‐sensor architectures, clarifying physical coupling between sensing and computation. The framework connects neural and synaptic device functions with recent advances in optical, mechanical, and chemical sensing, compares energy consumption and ...

The Bitter Taste of Brazil's Temporary Import Ban on Robusta Coffee

open access: yesAgribusiness, EarlyView.
ABSTRACT Brazil, a leading Robusta coffee producer and exporter, faced a significant drought in 2016–2017, which drastically reduced production and depleted stocks. Consequently, Brazil temporarily permitted the import of one million 60‐kg bags of Robusta coffee in the spring 2017. An import ban was imposed shortly afterward due to lobbying by domestic

Online Thermal Analysis of Batch Roasted Coffee Beans [PDF]

open access: yes, 2014
We constructed and instrumented a fluidised-bed coffee roaster. This work has been carried out as part of a search for the “ideal point”, which is the point in time when an expert roaster would terminate the roast in order to yield beans that produce the

Effect of heating temperature on volatiles of roasted laver.

open access: yesNIPPON SUISAN GAKKAISHI, 1987
The effect of the heating temperature on volatile components of roasted lever Porphyra tenera were studied. Volatile components of dried lover and three roasted lavers heated at 140, 200, and 250°C were analyzed by gas chromatography and gas chromatography-mass spectrometry.
