Looking to sea urchins for stronger ceramic foams
Ling Li, assistant professor in Virginia Tech's Department of Mechanical Engineering, has unlocked a mystery in the porous microstructures of sea urchin exoskeletons that could lead to the creation of lightweight synthetic ceramics. His findings were.....»»
Freshwater oysters could be key to developing stronger, "greener" adhesives
If you think oysters are just delicious seafood, think again. Freshwater oysters produce an adhesive that may hold the secret to developing more environmentally friendly glues with applications from dental care to construction and shipping. An intern.....»»
iPhone Diary: iPhone 16 Pro Max ordered, with Apple managing to surprise me
I said before the keynote that I expected to be ordering an iPhone 16 Pro Max, and that was going to be largely down to the functionality of the Camera Control button. This turned out to be an even stronger draw than I’d expected. Despite the bu.....»»
Experimental evidence links plant diversity to ecosystem multifunctionality through multitrophic diversity
A study led by Prof. Liu Xiaojuan from the Institute of Botany of the Chinese Academy of Sciences (IBCAS) has demonstrated that the association between multitrophic diversity and ecosystem multifunctionality is stronger than the relationship between.....»»
Dual-feedback mechanism can enhance anti-oxidation coatings in fiber composites
Fiber-reinforced ceramic matrix composites (CMCs) have been the primary choice for radome materials in hypersonic vehicles due to their high toughness, strength, and other advantageous properties. However, oxidation by oxygen in the atmospheric envir.....»»
Researchers solve long-standing mystery of alumina surface structure
Aluminum oxide (Al2O3), also known as alumina, corundum, sapphire, or ruby, is one of the best insulators used in a wide range of applications: in electronic components, as a support material for catalysts, or as a chemically resistant ceramic, to na.....»»
Summer storms found to be stronger and more frequent over urban areas
Summer storms are generally more frequent, intense and concentrated over cities than over rural areas, according to new, detailed observations of eight cities and their surroundings. The results could change how city planners prepare for floods in th.....»»
Researchers develop innovative method to simplify manufacturing process of cellular ceramic
A study led by the School of Engineering of the Hong Kong University of Science and Technology (HKUST) has developed an innovative method that overcomes the limitations of traditional additive manufacturing (3D printing), significantly simplifying an.....»»
Why do materials get stronger when they are deformed? Research sheds light on universal mechanisms of work hardening
The earliest blacksmiths in the Bronze and Iron Ages figured out that when they deformed metal through bending or hammering, it became stronger. This process, known as work or strain hardening, is still used widely in metallurgy and manufacturing tod.....»»
Nontoxic ceramic could replace lead-based electronic components
The ceramic produced in Prof. Igor Lubomirsky's lab at the Weizmann Institute of Science seemed too good to be true. It belongs to a class of materials that are the backbone of many essential technologies but that unfortunately also create an environ.....»»
We need far stronger support systems in the fight against gender-based violence, says expert
The COVID-19 pandemic brought renewed attention to the rising rates of gender-based violence, highlighting an ongoing, but growing, crisis......»»
Physicists develop new model that describes how filaments assemble into active foams
Many fundamental processes of life, and their synthetic counterparts in nanotechnology, are based on the autonomous assembly of individual particles into complex patterns. LMU physicist Professor Erwin Frey, Chair of Statistical and Biological Physic.....»»
How does organic farming benefit honey bees?
Organic farming and flower strips promote the health of honey bees. In their vicinity, colonies grow stronger and are generally healthier. This is most likely because the insects have a diverse and continuous food supply there and are less exposed to.....»»
Achieving enhanced energy storage performance and ultra-fast discharge time in tungsten-bronze ceramic
It is widely recognized that achieving high energy storage density and efficiency in ferroelectric ceramics relies on their ability to exhibit high saturation polarization and low residual polarization, which are essential for excellent energy storag.....»»
Google Pixel 9 Pro versus Apple iPhone 15 Pro: Flagship Face-Off!
Apple's grasp on the North American smartphone market is undoubtedly impressive, and it's no secret that Google wants to establish a stronger foothold here with the Pixel 9 Pro. The post Google Pixel 9 Pro versus Apple iPhone 15 Pro: Flagship Face-Of.....»»
Extreme Weather Poses a Challenge for Heat Pumps
Stronger winds, bouts of extreme low temperature, and higher humidity pose difficult but surmountable challenges for heat pumps......»»
Health-threat "forever chemicals" removed from water with 3D-printed ceramic ink
Engineers have invented a new way to remove health-harming 'forever chemicals' from water—using 3D printing......»»
Ce-doped yttria transparent ceramic: A new ultraviolet-shielding material for extreme conditions
Ultraviolet (UV) radiation can break most of the chemical bonds in organic matter, and prolonged exposure to ultraviolet light can cause significant harm to humans and objects. In response, UV-shielding materials have been developed to fulfill variou.....»»
As California seeks to curb groundwater declines, farmers in one county fight back in court
With long-term declines in groundwater levels putting thousands of domestic wells at risk and causing the ground to sink in parts of the San Joaquin Valley, state regulators are moving forward with efforts to force local agencies to take stronger ste.....»»
New research on 3D-printed materials toward future generations of stronger, lighter plastics
A new analysis of the deformation mechanisms which cause 3D-printed materials to fail under strain could help create future generations of stronger, lighter plastics, unlocking transformative benefits for industry......»»
An effective strategy to inhibit grain coarsening: Construction of multi-element co-segregated grain boundary complexion
To date, ceramic scientists have devised various strategies to impede grain coarsening. The utilization of nano-sized precursor powder can not only facilitate the densification process, but also yields bulk ceramics with reduced grain sizes compared.....»»
