These parts contain additives that contribute to their flexibility and durability, but these potentially harmful compounds can leak into drinking water, according to a small-scale study. The authors report that the released compounds, which are typically linked to tire pollution, also transformed into other unwanted byproducts.

Any pumping application -- from industrial scales to heating systems at home -- would benefit from a reduction in energy demands. Researchers now showed how pulsed pumping can reduce both friction from and energy consumption of pumping. For this, they took inspiration from a pumping system intimately familiar to everyone: the human heart.

Such a phase transition occurs, for example, when water freezes. However, in certain metals there are phase transitions that do not exist in the macrocosm. They arise because of the special laws of quantum mechanics that apply in the realm of nature's smallest building blocks. It is thought that the concept of electrons as carriers of quantized electric charge no longer applies near these exotic phase transitions. Researchers have now found a way to prove this directly. Their findings allow new insights into the exotic world of quantum physics.

To get the droplets to levitate, they use solutocapillary convection, which occurs when a surface tension gradient is formed by nonuniform distribution of vapor molecules from the droplet at the pool surface. Further exploring the effects of various external conditions on self-sustained droplet levitation will reveal whether it can be harnessed and adapted for microbiology and biochemistry applications.

In fluid-driven robotic systems, pumps control the pressure or flow of the liquid that powers the robot's movement. Most pumps available today for soft robotics are either too large and rigid to fit onboard, not powerful enough for actuation or only work with specific fluids. Researchers have now developed a compact, soft pump with adjustable pressure flow versatile enough to pump a variety of fluids with varying viscosity, including gin, juice, and coconut milk, and powerful enough to power soft haptic devices and a soft robotic finger.

Their work reveals complex hydrodynamics involved in forming horizontal air cavities and the transition between floating and skipping. One of the team's key findings is that as the pulling force and speed of the spheres increase, their behavior becomes more irregular. They also discovered larger pulling angles result in different air-cavity lengths, larger skipping distances, and earlier water exit behavior.

Perhaps the most broadly known is global warming, which is caused by heat building up in various parts of the Earth system, such as the atmosphere, the ocean, the cryosphere and the land. 89 percent of this excess heat is stored in the oceans, with the rest in ice and glaciers, the atmosphere and land masses (including inland water bodies). An international research team has now studied the quantity of heat stored on land, showing the distribution of land heat among the continental ground, permafrost soils, and inland water bodies. The calculations show that more than 20 times as much heat has been stored there since the 1960s, with the largest increase being in the ground.

Researchers chemically analyzed how volatile compounds in a set of 25 whiskies responded to the addition of water, including bourbons, ryes, Irish whiskeys and both single malt and blended Scotches. They also had a trained sensory panel assess six of those whiskies, three Scotches and three bourbons. Both tests found that adding a little water could change how the whiskies smelled, but after 20%, they may start to have the same aroma. Since smell and taste are often closely linked, this likely affected the spirit's flavor as well.

The team created a nanofibrous membrane with electrospinning, in which a liquid polymer droplet is electrified and stretched to make fibers, and increased the roughness of the membrane surface by loading it with silver nanoparticles. In water, this rough surface promotes a stable layer of water, which acts as a barrier to prevent oil droplets from entering the membrane.

They found the effect of secondary atomization was significant and predictable: The smaller droplets were easier to sweep up by the firearm's gases and turn around toward the victim. This discovery could explain how a short-range shooter might stay clean from blood stains.

They are traditionally collected and removed from water by filtering through meshes, which is inefficient. Researchers have now developed a high-enrichment microfluidic device that utilizes acoustic focusing to collect and remove 10--200 ?m MPs from wastewater without recirculation. Its collection rates and enrichment ratios ranged approximately from 70--90% and 50--100, respectively on test samples.

The phosphorylated yeast is expected to be utilized as a material for recovering useful metals and removing toxic metals, thereby contributing to the realization of a metal resource-circulating society.

But the field of molecular robotics is starting to change that. Like the formation of complex living organisms, molecular robots derive their form and functionality from assembled molecules stored in a single unit, i.e., a body. Yet manufacturing this body at the microscopic level is an engineering nightmare. Now, a team has created a simple workaround.

These items pile up in landfills, and many biodegradable versions stick around for months, requiring industrial composting systems to fully degrade. Now, researchers have created a sturdy, lightweight material that disintegrates on-demand -- and they made it from sugar and wood-derived powders.
