Integration of on-farm biodiesel production with anaerobic digestion to maximise energy yield and greenhouse gas savings from process and farm residues

open access: yes, 2011
Anaerobic co-digestion of residues from the cold pressing and trans-esterification of oilseed rape (OSR) with other farm wastes was considered as a means of enhancing the sustainability of on-farm biodiesel production.

Enabling Additively Manufactured Electronics Through Laser Induced Graphene and Copper Deposition on Fully‐Aromatic Polyimides

open access: yesAdvanced Materials Technologies, EarlyView.
This article introduces a hybrid manufacturing approach to create conductive pathways in additively manufactured fully‐aromatic polyimides. This is enabled through a combination of high‐resolution laser scribing process for fabricating graphene and metallizing it with electrodeposition of copper to further increase conductivity.

Oil and energy price volatility

open access: yesEnergy Economics, 2007
It is commonly believed that since the 1973 oil crisis, oil and energy prices have been more volatile than other commodity prices. This study examines monthly producer prices for thousands of products over the period January 1945 through August 2005.

How to Manufacture Photonic Metamaterials

open access: yesAdvanced Materials Technologies, EarlyView.
Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.

Efeitos das condições ambientais sobre o teor e variabilidade dos óleos voláteis de dalbergia frutescens (Vell.) Britton (Fabaceae)

open access: yesQuímica Nova, 2012
The volatile oils of Dalbergia frutescens were obtained by hydrodistillation on a Clevenger-modified apparatus for every month of one year and assessed on GC/MS and GC/FID detectors for qualitative and quantitative analyses.

Controlled Air Gap Formation between W and TiO2 Films via Sub‐Surface TiO2 Atomic Layer Etching

open access: yesAdvanced Materials Technologies, EarlyView.
Delivering SiH4 and WF6 to a lined array of TiO2 films produces a thin film of tungsten while simultaneously, the underlying TiO2 is removed. When the W‐coated TiO2 structure is exposed to further etching cycles after deposition, TiO2 etching continues vertically and laterally, creating a self‐supported W structure and a vacant air gap.

Application of Volatile Antifungal Plant Essential Oils for Controlling Pepper Fruit Anthracnose by Colletotrichum gloeosporioides

open access: yesPlant Pathology Journal, 2015
Anthracnose caused by Colletotrichum gloeosporioides has been destructive during pepper fruit production in outdoor fields in Korea. In vitro antifungal activities of 15 different plant essential oils or its components were evaluated during conidial ...

Pattern formation without heating in an evaporative convection experiment [PDF]

open access: yes, 2003
We present an evaporation experiment in a single fluid layer. When latent heat associated to the evaporation is large enough, the heat flow through the free surface of the layer generates temperature gradients that can destabilize the conductive ...
