BioDegradation of Refined Petroleum Hydrocarbons in Soil [PDF]

Journal of Applied Sciences and Environmental Management, 2010
Carbon-dioxide production and hydrocarbon degradation of refined petroleum hydrocarbon in soils treated with 5% gasoline, kerosene and diesel oil were investigated. Soil for study was bulked from around acar park in Port Harcourt. Soil samples were collected at weekly intervals for four weeks and subsequently at monthly intervals for four months ...

Supplying Synthetic Crude Oil from Canadian Oil Sands: A Comparative Study of the Costs and CO2 Emissions of Mining and In-Situ Recovery [PDF]

, 2010
High crude oil prices and the eventual decline of conventional oil production raise the issue of alternative fuels such as non-conventional oil. The paper describes a simple probabilistic model of the costs of synthetic crude oil (SCO) produced from ...

Transmembrane Activation of Catalysis and Protein Refolding in Synthetic Cells by Enzymes and Nanozymes

Advanced Functional Materials, EarlyView.
Synthetic cells are engineered herein to respond to an external chemical messenger by the activation of intracellular catalysis. The chemical messenger molecules are catalytically generated by an extracellular enzyme or a mineral surface, whereas the intracellular catalysis emerges via direct enzyme activation or via protein refolding.

Native Lignin Migration and Clustering in Wood: Superhydrophobic, Antimold, and Tribonegative Layers for Rain‐Driven Electrification

Advanced Functional Materials, EarlyView.
This study proposes a sustainable solution for rainwater‐driven energy harvesting by harnessing the intrinsic properties of lignin in wood. The first demonstration of an all‐wood tribonegative material for liquid–solid triboelectric nanogenerators is presented, eliminating the need for fluorine‐containing polymers and functional additives. Abstract The

The Performance of Carbon-Based Nanomaterials in Different Base Oils and an Oil Blend

Lubricants
Different carbon-based nanomaterials (fullerenes, graphene, SWCNTs, and SWCNT-COOH) were tested as additives in a base mineral oil, SN150; rapeseed oil (RSO); and a 50/50 by volume blend of the two using an HFRR (high-frequency reciprocating rig) tester ...

Supramolecular Zwitterionic Hydrogels for Information Encryption, Soft Electronics and Energy Storage at Icy Temperature

Advanced Functional Materials, EarlyView.
A series of ACHPES‐based hydrogels are developed and realizing multiple functions like anti‐fouling properties, alkali‐induced color/fluorescence‐changing ability and strain sensing. Furthermore, the hydrogels show excellent anti‐freezing performance, whose optical, mechanical and electrical properties remain stable at −47.3 °C.
