Abstract:
... In this study, total petroleum hydrocarbon (TPH) removal from fuel-contaminated field soil was investigated. The influence of the washing method (washing before/after sieving), washing time, soil-to-water ratio, and soil particle size on TPH removal efficiency was evaluated under constant stirring speed. Washing the whole contaminated soil is more efficient than separating the soils into particle ...

Abstract:
... Redox methods represented by Hummers’ method are the most frequently-used pathways to prepare graphene, but to date still very low-efficient, because of its time-consuming washing and hard reduction process. Here we report an intermittent microwave-exfoliated non-expansive graphite oxide (GtO) process to prepare a wrinkled graphene with a high reduction degree (C/O: 19.0), a high defect degree, an ...

Abstract:
... Conveyance, i.e., leaving one's appliance in the dwelling when moving out, shortens the expected length of ownership of an appliance and may therefore lead to the purchase of less energy-efficient appliances. Employing a demographically representative survey in Spain, this paper uses statistical-econometric analyses to explore the effects of conveyance on stated adoption of energy-efficient applia ...

Abstract:
... Measures of tooth wear have widespread use as proxies in palaeobiological reconstructions. In order to apply these proxies, an understanding of potential influence factors on wear is important. The processes during the digestion in the ruminant organism lead, possibly inadvertently, to a washing of material before it is regurgitated for rumination chewing. Therefore, ruminants might experience les ...
