Researchers at Ames Laboratory have successfully decomposed lignin into stable components using a phosphate-modified ceria catalyst, producing useful industrial precursors for nylon production. The process eliminates the need for hydrogen from natural gas and uses an energy-conserving alcohol-based hydrogenation process.
Broccoli sprouts contain higher levels of glucosinolates, a key compound for their potential health benefits. High pressure processing has been found to maintain these beneficial compounds while eliminating bacteria.
Researchers found that a heat treatment under hydrogen doubles the life span of charge carriers in metal oxide photoelectrodes, leading to improved photocurrent under sunlight. This breakthrough could potentially reduce costs and increase stability for commercialization.
Since 1950s, over 9.1 billion tons of plastic have been manufactured, with the majority ending up in landfills or natural settings. Recycling plastic merely delays disposal unless it reduces new production, while incineration can have negative environmental and health effects.
Middle Stone Age humans developed intentional heat treatment of silcrete rock to facilitate the flaking process, which impacted all subsequent stages of silcrete tool production and use. The authors suggest that this technique may provide direct evidence of the extensive use of fire applied to a whole lithic chain of production.
A brief blast of heat can kill bedbugs on the exterior of soft-sided luggage, according to a study by University of California, Irvine entomologist Catherine Loudon. The six-minute treatment at temperatures between 158 and 167 degrees effectively killed all bedbugs on the exterior, including those under zipper flaps and decorative piping.
A heat treatment of 70-75oC kills all bed bugs on the outer surface of luggage in six minutes, even those hidden under zipper flaps. At room temperature, only 3% of bugs move inside during a 24-hour period.
Researchers at PNNL have developed a stronger titanium alloy using a novel nanostructure, with potential applications in lightweight vehicle parts. The alloy achieved a 10-15% increase in strength, making it suitable for high-strength-to-cost ratio and greater fuel economy.
Purdue researchers are working to learn precisely how much heat to apply and how frequently to use heat treatment for a given hair type without destroying it. The team has developed a prototype system that simulates a flat iron passing over hair, using an infrared microscope to study the behavior of heat on different hair types.
Researchers at the University of Pittsburgh are exploring a new method to treat high-saline water from hydrofracturing and other processes by utilizing waste heat from thermoelectric plants. The goal is to develop a cost-effective technology that can recover clean water and reduce waste disposal costs.
A new method combining 3D printing and thermal reflow treatment creates tactile objects with detailed lines and curves, making books and teaching materials more accessible to the visually impaired. The technology reduces production time from months to hours, using eco-friendly and durable materials.
The formation of a hierarchical microstructure in superalloys has been observed for the first time using TEM and APT. Researchers found that spherical and plate-like gamma particles are key to the alloy's mechanical properties.
Researchers found that cannula gauge, tip length, set temperature, and lesion time significantly impact heat lesion width and length in radiofrequency treatments. The study provides new insights for pain management and treatment precision.
A new study explores how processing affects mango varieties' flavor and texture, revealing that some characteristics are lost during processing. The findings can help manufacturers choose the right variety for their mango-flavored products.
Researchers at Ohio State University successfully treated two patients with cutaneous leishmaniasis, a parasitic skin infection common in tropical regions, using heat therapy. The long-term effectiveness of this treatment, especially in people with compromised immune systems, makes it an appealing alternative to traditional drug therapy.
Researchers investigated the effect of heat treatment on the superconducting properties of Ag-doped Sr0.6K0.4Fe2As2 compounds and found that increasing heat treatment temperature improves Jc, while Tc remains unaffected. The study demonstrated that Ag doping enhances Jc at higher sinter temperatures.
Magnetic nanoparticles are injected into tumors to generate heat for cancer treatment. Magnetic relaxometry measures the relaxation of magnetic moments to determine particle quantity, allowing for selective tumor treatment.
Researchers have found that tumors can be treated with extreme heat or moderate heat using ultrasound techniques, showing promise for a new cancer therapy option. Hyperthermia has been shown to increase radiation damage and enhance chemotherapy treatments.
Researchers discovered that early modern humans employed pyrotechnology to increase the quality and efficiency of their stone tool manufacturing process, requiring complex cognition and possibly language. The technology transformed a poor-quality stone into an excellent raw material for highly advanced tools.
A UT research team aims to develop cost-effective methods for analyzing and cleaning up contaminated sites with dense non-aqueous phase liquids (DNAPLs), which pose a major problem at many DOD facilities. The project could lead to significant cost savings, potentially running into the billions of dollars.
Scientists have developed a method for delivering thermal ablation directly to tumor cells using nanotechnology and molecular imaging. By attaching magnetic iron-containing bioprobes to cancer cells and heating them with an alternating magnetic field, researchers were able to weaken and destroy malignant cells without damaging nearby h...
A new study by Stanford University researchers found that doubling carbon dioxide levels significantly reduces plant species in the wild. Exposure to high CO2 gas for three years caused a nearly 20% decline in wildflowers and an overall eight percent drop in plant diversity.
