Abstract BACKGROUND: Mycosphaerella fijiensis Morelet causes black sigatoka, the most important disease in bananas and plantains. Disease control is mainly through application of systemic fungicides, including sterol demethylation inhibitors (DMIs). Their intensive use has favoured appearance resistant strains. However, no studies have been published on possible resistance mechanisms. RESULTS: In this work, CYP51 gene was isolated sequenced 11 M. strains that had shown different degrees...
Advanced fuel design through integration of chemistries leading to different components: alcohols (blue); ethers (green); and olefins, parafins, aromatics (yellow).
Being able to manipulate mass flow is critically important in a variety of physical processes chemical and biomolecular science. For example, separation catalytic systems, which requires precise control diffusion, are crucial the manufacturing chemicals, crystal growth semiconductors, waste recovery biological solutes or production artificial kidneys. Coordinate transformations metamaterials powerful methods achieve manipulation molecular diffusion. Here, we introduce novel approach obtain...
Ethanol is catalytically upgraded to diesel.
Recent advances in the design of metamaterials that control diffusive transport processes have enabled efficient devices to manipulate heat conduction. In contrast, mass diffusion with metamaterial has been largely unexplored. Mass is critically important multiple research areas ranging from electronic and energy materials chemical biological systems. this work, we introduce a physical approach take into account fundamental mechanisms behind transport. We demonstrate concentration...
We systematically study the upgrading of ethanol toward middle distillates with desired properties.
This study presents an optimization framework to identify economically viable pathways for lignin valorization in biorefineries that employ biological upgrading. The economic potential converting from hardwood, softwood, and herbaceous plants into valuable bioproducts is evaluated. research indicates the production of 2-pyrone-4,6-dicarboxylic acid (PDC) hardwood most promising, with estimated net present value $771.41 million internal rate return 19.73% through dilute pretreatment,...
We introduce a new class of metamaterial device to achieve separation compounds by using coordinate transformations and theory. By rationally designing the spatial anisotropy for mass diffusion, we simultaneously concentrate different in locations, leading mixtures across membrane. The into their constituent is critically important biophysics, biomedical, chemical applications. present practical case where mixture oxygen nitrogen diffusing through polymeric planar matrix separated. This work...
Carbon and carbon dioxide can be concurrently converted using light to monoxide via the reverse-Boudouard reaction.
A simulated fuel storage tank was used to study biodeterioration of linear low-density polyethylene over 100 days. The system consisted a water layer inoculated with microorganisms and diesel/biodiesel. Biodeterioration characterized measuring: biofilm growth, surface chemistry, crystallinity, topography. Results showed greater accumulation at higher biodiesel concentrations. Polyethylene biodegradation measured as consumption oxidized species, increase in contact angle reduction electron...

Recent advances in coordinate transformations of Fick's equation have paved the way for design metamaterial devices that can manipulate mass diffusion flux. The control paths has a great potential novel catalytic and separation systems chemical biomolecular engineering. In order to explore these new applications, it is necessary understand transformation devices. this work, we present comprehensive study on impact structure material properties resultant physical concentrator shells....
The lack of good quality planting material farmers' cassava varieties, produced locally and at low cost, is a major constraint limiting the expansion production in Colombia. This article describes adaptation conventional propagation to low-input scheme for rural tissue-culture multiplication, developed run by small, resource-poor farmers (referred this as an informalfarmers' seed system). Developed through two-phase participatory process group women farmers, non-governmental organization...
Abstract To date the design of membranes for gas separations has relied on isotropic materials that control magnitude mass flux. However, flux is a vector quantity and controlling its direction essential complete manipulation diffusion processes.
