Transition metals such as iron are reactive components of environmentally relevant surfaces. Here, dark reaction of Fe(III) with catechol and guaiacol was investigated in an aqueous solution at pH 3 ...

From the mud, straw, and gypsum mixtures of ancient Egypt's monumental pyramids to the sophisticated underwater material ...

A combination of sewage overflows and coastal winds could be sending billions of airborne microplastic particles into the ...

A thin layer found in the top few centimeters of soil plays a big role in its ecology. Biocrust is built, maintained and ...

Tooth enamel, the hardest substance in the human body, may be at risk of gradual and permanent wear from chewing vegetables.

Soil is the thin layer of material covering the earth’s surface and is formed from the weathering of rocks. It is made up mainly of mineral particles, organic materials, air, water and living ...

The importance of water-soluble organic matter (WSOM) on the hygroscopic growth of particles is recognized, yet roles of different categories of WSOM are under debate. We segregated WSOM from ...

If you have houseplants, you've probably noticed small white specks in the potting mix. Here's what they are, and how to know ...

Tiny plastic particles are contaminating food and beverages not just from plastic containers, but also from painted caps on glass bottles and industrial food processing equipment.Shannon Osaka reports ...

The ultimate shear strength, and therefore resistance to smearing, of a soil depends mainly on the composition of the soil’s particles, the amount of water in the soil, and how badly compacted the ...

Traditionally, the HF or HF-HCl treatment has most commonly been used to recover bulk humin from inorganic soil colloids (Stevenson, 1994; Rice, 2001; Calace et al., 2007). The soluble fraction can ...

We propose a novel strategy for optical trapping and sorting of micro-nano particles that does not involve the flow of the immersion medium. The method employs the size- and velocity-dependent ...
