Anacail

anacail

Anacail was formed to commercialise technology developed at the Glasgow University’s School of Physics and Astronomy. The technology can rapidly and safely turn some of the oxygen inside packaged food into ozone, a very effective germicide. Plasma generated by a retractable device held briefly against the surface of plastic or glass packaging splits the bonds between oxygen molecules (O2) inside the packaging which then reform as ozone (or O3). The ozone naturally returns to its original state after just a couple of hours – more than enough time for any mould, fungi or bacteria on the packaging’s contents to be destroyed without adversely affecting its taste.
The product’s effectiveness as a germ-killer also extends food’s shelf-life by at least one extra day, and has been proven at UK labs including Campden BRI in Gloucestershire, where tests have shown an increase in shelf-life for products including bread and muffins, and a significant reduction of many pathogens in poultry including campylobacter, pseudomonas, and E.coli. The name Anacail means ‘shield’, ‘preserve’ or ‘protect’ in Gaelic.

Oxford Performance Materials  OsteoFabTM Medical Devices and ImplantsReceives FDA approval.

Breaking the mold for the medical device market.

Utilizing the most advanced materials and technology, our OsteoFabTM process can reproduce exactly what you design, or exactly what nature intended by “printing” medical implants derived directly from a CT Scan or MRI file for a perfect anatomical fit with our own OXPEKK®-IG polymers.

However, this technology allows us to go beyond merely replicating shapes: we also have the ability to meet specific performance requirements as anatomically applicable. Through our proprietary “Coherent Implantology Process”, fit, form and bio-function are digitally calculated, constructed, and then produced. http://www.oxfordpm.com/biomedical_parts.html

DLVR Therapeutics Inc

DLVR_PPT_Illustration

DLVR’s innovative technology is based on the synthesis and use of an HDL-mimetic phospholipid-based nanoparticle called HPPS (HDL-like Peptide-Phospholipid Scaffold).

DLVR Therapeutics Inc. is based in Toronto. Co-founded by University Health Network, the Ontario Institute for Cancer Research and MaRS Innovation, the Company is developing an innovative, HDL-like Peptide-Phospholipid Scaffold (HPPS) nanoparticle delivery system. HPPS enhances cell targeting and bypasses endosomal degradation, two common problems which beset contemporary delivery systems. Mechanistically, HPPS appropriates HDL’s affinity for its natural ligand, Scavenger Receptor B1 (SR-B1) to preferentially target this receptor.  Upregulated in many solid tumors such as breast, colorectal, pancreatic and ovarian, SR-B1 facilitates direct delivery of payload to the cytosol of tumor cells. The ultra-small HPPS particle is suitable for a variety of different RNAi payloads. The company’s development strategy is to collaborate with partners that have developed novel RNAi therapeutics that require an innovative delivery technology.

Nano-sandwich technique improves efficiency of solar cells

The active layer (blue line) is sandwiched between layers of dielectric material.

 

 

 

 

 

Researchers from North Carolina State University have found a way to create much slimmer thin-film solar cells without sacrificing the cells’ ability to absorb solar energy. Making the cells thinner should significantly decrease manufacturing costs for the technology (see paper in Nano Letters: “Dielectric Core–Shell Optical Antennas for Strong Solar Absorption Enhancement”).

“We were able to create solar cells using a ‘nanoscale sandwich’ design with an ultra-thin ‘active’ layer,” says Dr. Linyou Cao, an assistant professor of materials science and engineering at NC State and co-author of a paper describing the research. “For example, we created a solar cell with an active layer of amorphous silicon that is only 70 nanometers (nm) thick. This is a significant improvement, because typical thin-film solar cells currently on the market that also use amorphous silicon have active layers between 300 and 500 nm thick.” The “active” layer in thin-film solar cells is the layer of material that actually absorbs solar energy for conversion into electricity or chemical fuel.

Plasmonics used for early detection of lung cancer

The BiopSys team has already developed the technique to the point where it produces “a higher-fidelity, more sensitive measurement than in any existing commercial technology,” Walker says. “That’s a good first step. But that’s in a lab setting.” He hopes that companies will soon seek to license the technology, for which his team has made several patent applications. “The hope and expectation is that, as this technology develops, it gets translated onto end users – companies that will manufacture the devices, and doctors that will use them.” That could take another five to 10 years, he says.

D5 No Harm to Environment

 

………a three-year debate over the need to regulate ­decamethylcyclopentasiloxane, also known as D5, ended when federal Environment Minister Peter Kent concluded that it does not harm the environment.

D5 and related siloxanes are noted for their ability to provide a quick-drying, non-oily feel to everything from shampoo to sunscreen. In January 2009, a screening assessment, conducted as part of Canada’s ongoing Chemicals Management Plan, flagged D5 as potentially harmful to the environment. However, in July 2009 the Silicones Environmental, Health and Safety Council of North America submitted a Notice of Objection. In response to this, then-environment minister Jim Prentice established a scientific board of review to look into the matter. The board issued its report last fall.

The Report of the Board of Review for Decamethylcyclopentasiloxane (Siloxane D5) concluded that, due to its high vapour pressure, D5 tends to partition primarily into air, where it is quickly degraded into harmless compounds by indirect photolysis. Although it can persist in sediments and accumulate in sediment-dwelling organisms, it does not biomagnify through the food chain. The report noted that “siloxane D5 will not accumulate to sufficiently great concentrations to cause adverse effects in organisms in air, water, soils, or sediments.”

Chemical analysis of collagen used in Archaeology Research Studies

Thirty-seven skeletons found in a mass burial site in the grounds of St John’s College may not be who they initially seemed, according to Oxford researchers studying the remains.

Researchers from the Research Laboratory for Archaeology and the History of Art at the University of Oxford carried out a chemical analysis of collagen from the bones and teeth of some of the individuals and concluded that they had had a substantial amount of seafood in their diet. It was higher in marine protein than that found in the local Oxfordshire population, as recorded in existing data.

Testing was done using strontium isotope analysis of tooth enamel, a technique which provides evidence of where an individual lived when the tooth formed. Strontium, a naturally occurring element in rocks and soils, is absorbed by plants and animals, and can be found in trace amounts in mammalian teeth. Strontium isotopes reflect the particular geological conditions so even small traces can be revealing of that individual’s location.

The researchers also looked at data relating to previous research in which an isotopic analysis of dismembered skeletons found in a burial pit at the Weymouth Ridgeway in Dorset identified the individuals as Scandinavian Viking raiders. The decapitated skeletons in Dorset were dated at between 890 and 1030 AD, and were thought to be a group of young men from different countries across Scandinavia. The isotopic analysis of the Dorset group when compared with the individuals found in the mass burial site at St John’s College show similarities.
