SAN CLEMENTE, Calif., January 17, 2023--(BUSINESS WIRE)--Land Science®, a division of REGENESIS®, and the recognized leader in contaminant vapor intrusion mitigation technologies, was recently awarded a U.S. patent for the innovative use of a reinforced geomembrane comprised of an encapsulated, metalized layer and installed with Nitra-Core™, a spray-applied nitrile-modified asphalt. This patented innovation provides 100 times more chemical resistance than other solutions and is integral to the enhanced protection built into Land Science’s popular MonoShield® and TerraShield® contaminant vapor barrier systems.

As part of the U.S. patent process, Land Science scientists presented lab testing data that compared the design of the new vapor intrusion (VI) barrier technology to commonly used high-density polyethylene (HDPE) systems.

"In our lab study, we discovered TerraBase+ provided 100 times more protection from TCE vs. the HDPE tested," said Vice President of Quality and Process Improvement Kristen Thoreson, Ph.D., who is a co-inventor on the patent along with principal engineer Hieu Nguyen and REGENESIS President and CEO Scott Wilson. "This represents a significant improvement and ensures a safer environment for sites where contaminant vapor intrusion is a health concern."

Land Science’s patented material design offers superior protection because it incorporates metalized film, a material proven to be highly effective at preventing the diffusion of contaminant gases. The advanced composite membrane prevents corrosion of the encapsulated metalized film and provides multiple layers of protection — including a reinforced grid geomembrane and geotextile. This reinforcement ensures greater tensile strength, enhances durability and minimizes the potential for punctures during installation, which often occurs in demanding construction environments.

The chemically resistant and proven design improvements apply to both MonoShield and TerraShield contaminant vapor barrier systems and are marketed through the Land Science team of technical sales representatives based throughout North America.

U.S. Air Force Brig. Gen. Patrick Ryder briefed the media about the Chinese spy balloon over the U.S. AP Photo/Alex BrandonOfficials of the U.S. Department of Defense confirmed on Feb. 2, 2023, that the military was tracking what it called a “spy balloon” that was drifting over the continental United States at an altitude of about 60,000 feet. The following day, Chinese officials acknowledged that the balloon was theirs but denied it was intended for spying or meant to enter U.S. airspace. U.S.

STORY: A California startup that uses rocks to soak up carbon dioxide from the air has teamed up with a Canadian company to mineralize the greenhouse gas in concrete. "Concrete is an amazing way to store CO2 because it mineralizes the CO2, it turns CO2 into a carbonate, into a rock."The technological tie-up is a first of its kindand companies say it could provide a model for fighting climate change.U.N. scientists say that removing billions of tons of carbon dioxide from the atmosphere will be necessary to limit climate change. To do that, two things are needed. First, capturing CO2 with nature or technology, and second, locking it up for centuries.California-based Heirloom Carbon Technologies and Canada's CarbonCure are doing just that. Heirloom CEO Shashank Samala explains:“Heirloom uses something called limestone to pull carbon out of the atmosphere. // And limestone has this natural ability to pull carbon out of the atmosphere. The problem is it's just slow. So what we do here is just give it more superpowers to make it pull carbon much, much, much faster than it otherwise would. So what you're looking at here is we are taking limestone and spreading them out on trays and vertically stacking those trays and exposing it to the air. As the CO2 is brought in by the air, this limestone pulls up that carbon and sequesters it in the mineral.”Technology company CarbonCure then mixes the captured CO2 with concrete ingredients, turning it into a mineral that strengthens the building material.The process cuts the need for cement — the part of concrete with the biggest carbon footprint.Here's CarbonCure CEO Rob Niven.“So CO2 is actually a very powerful chemical when working with concrete. What you can do is you can actually react it with concrete to create a calcium carbonate nanomaterial. So we're turning CO2, this greenhouse gas, into a solid, a mineral format that can never be released again for thousands and thousands of years. But what's really key here is it also provides a performance benefit for that concrete. It gives it higher strength, which allows concrete producers to be able to optimize their production so they may require less cement. So they're able to gain these cost efficiencies by using CO2 in the right way, that allows them to eliminate that green premium.”But capturing and locking down carbon on a global scale will not be easy.Companies will have to build expensive, massive plants capable of capturing millions or billions of tons a year.The price of carbon also needs to fall. The U.S. government and industry broadly see $100-a-ton carbon dioxide as a reasonable price.Heirloom charges around $1,000 at present.Samala expects to be at $100 by the time his projects are soaking up millions of tons a year.Concrete itself is also controversial.The building material accounts for about 8% of global emissions of CO2. But for now, concrete's ubiquity is attractive, because there are currently few places to securely store carbon dioxide.“Carbon stays in the air for over a thousand years. So we need to find ways to permanently sequester it for thousands of years. There's not that many ways to do it. One is underground storage that we can safely and permanently store CO2 underground. The other is building materials like concrete."“Like many other folks, I want to wake up in the morning and know that we have an exciting future to look forward to, that my kids and grandkids and the future of humanity can look forward to. And, you know, some years ago, I realized that climate change is the biggest existential threat to humanity. And we need to find every which way to play our part in reducing emissions."

The world’s largest airplane, the Antonov An225 Mriya, was born in the Soviet Union in 1988. It measured 275 feet long and weighed nearly 420,000 pounds, designed to piggyback the USSR’s Buran space shuttle much the same way NASA plopped its shuttles on top of a modified 747. After the fall of the Iron Curtain, the world’s only Mriya was used for heavy air transport all around the world. It was destroyed last year, a casualty of Russia’s invasion of Ukraine. But now, it flies again — in Microsof
