New Research Creates Neutralizing Sponge for Dangerous Chemicals

Tuesday, June 16th, 2020

Dr Simon Holder, Reader in Organic Chemistry at the University of Kent (UK) and Dr Barry Blight, Associate Professor of Chemistry at the University of New Brunswick (Canada), have developed a new method for containing and deactivating neurotoxic chemicals like VX and sarin.

These weapons, known as nerve agents or neurotoxins, are highly potent and fast acting. Small doses can cause rapid paralysis and death, as the chemicals disrupt the connection between the body’s nerves and muscles.

These internationally banned liquids are aerosolised purposely to inflict damage on large geographical areas and are considered to be weapons of mass destruction (WMD’s).

In a project funded by the Defence Science and Technology Laboratory (Dstl) of the UK Ministry of Defence, the Kent team investigated new methods of bulk decontamination of chemical weapons.

The result of the research was the “Metal-organic framework (MOF)-containing polymer sponge”.

This is a sponge developed to swell and absorb dangerous neurotoxins and make them safer to handle, which also contains the MOF chemical catalyst, created to accelerate the chemical’s breakdown, diminishing the neurotoxins into safer components.

To research this safely, researchers used substances to simulate the presence of neurotoxins without risking exposure to dangerous chemicals. Following this, Dstl tested the prototype material with the real nerve agent to confirm the effect.

 “Less than five kilograms of the MOF-containing polymer sponge can absorb, immobilize, and safely destroy a 55-gallon drum of these toxic chemicals. It is very exciting to consider the potential this has in combatting dangerous chemicals in the future,” said Dr. Holder, who is also director of research at Kent’s School of Physical Sciences.

The research paper has been published in ACS Applied Materials and Interfaces: pubs.acs.org/doi/full/10.1021/acsami.9b18478

Study Shows How Microorganisms Survive in Harsh Environments

Saturday, May 9th, 2020

RESEARCH TRIANGLE PARK, N.C. — In northern Chile’s Atacama Desert, one of the driest places on Earth, microorganisms are able to eke out an existence by extracting water from the rocks they colonize.

An Army-funded project by researchers at the University of California, Irvine, Johns Hopkins University and University of California, Riverside gained an in-depth understanding of the mechanisms by which some cyanobacteria, an ancient group of photosynthetic microbes, survive in harsh environments.

The new insights, published in Proceedings of the National Academy of Sciences, demonstrate how life can flourish in places without much water in evidence – including Mars – and how people living in arid regions may someday be able to procure hydration from available minerals.

“The Army has a strong interest in how microorganisms well-adapted to extreme environments can be exploited for novel applications such as material synthesis and power generation within these harsh fielded environments,” said Dr. Robert Kokoska, program manager, Army Research Office, an element of U.S. Army Combat Capabilities Development Command’s Army Research Laboratory. “This study provides valuable clues for uncovering the evolved design strategies used by these native desert-dwelling microbes to maintain their viability in the face of multiple environmental challenges.”

Through work in the field and laboratory experiments, the research team focused on the interactions of Chroococcidiospsis, a desiccation-resistant species of cyanobacteria that is found in deserts around the world, and gypsum, a water containing calcium sulfate-based mineral. The colonizing lifeforms exist beneath a thin layer of rock that gives them a measure of protection against the Atacama’s extreme temperature, high solar irradiance and battering winds.

Co-author Jocelyne DiRuggiero, JHU associate professor of biology, traveled to the remote desert to collect gypsum samples and brought them back to her labs in the United States. She cut small pieces, where microorganisms could be found, and sent them to UCI for materials analysis.

In one of the most striking findings of the study, the researchers learned that the microorganisms change the very nature of the rock they occupy. By extracting water, they cause a phase transformation of the material – from gypsum to anhydrite, a dehydrated mineral.

According to DiRuggiero, the impetus for the published work came when Wei Huang, a UCI post-doctoral scholar in materials science & engineering, spotted data showing an overlap in concentrations of anhydrite and cyanobacteria in the gypsum samples collected in the Atacama.

“Our analysis of the regions of rock where microbes were colonized revealed a dehydrated phase of calcium sulfate, suggesting that they extract water from the rock to survive,” said David Kisailus, lead author and UCI professor of materials science & engineering. “We wanted to do some more controlled experiments to validate that hypothesis.”

DiRuggiero’s team then allowed the organisms to colonize half-millimeter cubes of rocks, called coupons, under two different conditions, one in the presence of water, to mimic a high-humidity environment, and the other completely dry. In the midst of moisture, the gypsum did not transform to the anhydrite phase.

“They didn’t need water from the rock, they got it from their surroundings,” Kisailus said. “But when they were put under stressed conditions, the microbes had no alternative but to extract water from the gypsum, inducing this phase transformation in the material.”

Kisailus’ team used a combination of advanced microscopy and spectroscopy to examine the interactions between the biological and geological counterparts, finding that the organisms bore into the material like tiny miners by excreting a biofilm containing organic acids, Kisailus said.

Huang used a modified electron microscope equipped with a Raman spectrometer to discover that the organisms used the acid to penetrate the rock in specific crystallographic directions – only along certain planes where they could more easily access water existing between faces of calcium and sulfate ions.

Kisailus said the project was a great demonstration of interdisciplinary research between microbiologists and materials scientists that may, one day, open doors to other forms of scientific discovery.

“Scientists have suspected for a long time that microorganisms might be able to extract water from minerals, but this is the first demonstration of it,” DiRuggiero said. “This is an amazing survival strategy for microorganisms living at the dry limit for life, and it provides constraints to guide our search for life elsewhere.”

Researchers said this study can benefit the Army Research Lab’s efforts in synthetic biology.

“These findings have drawn the interest of our lab as microbial survival mechanisms can be leveraged for biomanufacturing or sensing platforms in harsh military environments,” said Dr. Matthew Perisin of the lab’s biotechnology branch.

In addition to the Army, NASA also provided funding for this project.

COVID-19 AND THE SPECTRA DF-500 DECONTAMINATION SOLUTION

(Eagle, ID – Owyhee Group Companies) Owyhee Group Companies announced it is partnering with Spectra Shield Technologies to supply Spectra DF-500 disinfectant to its customers during the current COVID-19 pandemic. The objective is to provide a solution that kills and neutralizes biological threats like COVID-19. The Spectra DF-500 formulation grew out of the licensing and commercialization of a high-level disinfectant developed by the US Government at Sandia National Laboratories under the name DF-200. “The mainstay of the disinfectant world has been bleach and other toxic, corrosive, non-biodegradable and hazardous products. Under most residential conditions, these products do what they report. However, in cases of biohazards and pandemics there is a need for a higher level of efficacy and permanency. The competitive difference of Spectra DF-500 and Spectra DF-200 is the spectrum of kill and the environmental benefits”, notes Spectra Shield Technologies CEO Thad Weist.

The development of Spectra DF-500 came out of the U.S. government recognition of a need to combat bioterrorism after a nerve agent was released on a Tokyo subway in 1995, killing 12 and injuring another 1,000. The goal was to develop a solution to neutralize a wide spectrum of chemical and biological threats such as Anthrax, MRSA and other viral threats, with low-corrosivity and reducing the harmful effects to the environment. Unlike traditional disinfectants, Spectra DF-500 chemically cleaves the spore wall and neutralizes the mycotoxin inside. It also changes the osmotic pressure around the cell, which causes an imbalance in the internal cellular pressure resulting in the total collapse of the cellular membrane. In 2004, Kansas State University did a study with the DF-200 formula against SARS-Coronavirus with 100% deactivation in 1 minute.

The disinfectant is avaliable from Owyhee Group Companies in two different products: Spectra DF-500 and Spectra DF-200. Spectra DF-500 is EPA registered as a Decontaminant, Disinfectant, Virucide, Bactericide, Fungicide, Deodorizer, Algaecide, Antibacterial, Mildewstat and Cleaner. The Spectra DF-200 is a 3 part solution, including an accelerator to kill and neutralize chemical and biological threats and is EPA registered.

The liquids are combined at the time of application and are good for appoximately 8 hours. Unopened, DF-500 and DF-200 can be stored for 6 to 8 years, under controlled conditions. Each can be applied as a foam or as a liquid. An application device is not included in the delivery set. In a proper application, one gallon of fluid can cover 2,500 square feet. While biodegradable, neither product should be used directly on food. Both Spectra DF-500 and DF-200 have proven to be highly effective in destroying bio-films of select microorgansim in food processing facilities. Application of either product on food contact surface requires a potable water rinse.

The products are for sale at https://owyheegroup.com in 4 gallon kits that will cover approximately 10,000 square feet. The product is also available in 300 gallon totes for larger applications.

Interested parties can call Owyhee Group at 208.938.6086 or email [email protected] for quotations. The company has provided a special feature page covering the products at owyheegroup.com/product/decontamination.
