Research News: People with IBD have more microplastics in their feces, study says

Microplastics — tiny pieces of plastic less than 5 mm in length — are everywhere, from bottled water to food to air. According to recent estimates, people consume tens of thousands of these particles each year, with unknown health consequences. Now, researchers reporting in ACS’ Environmental Science & Technology found that people with inflammatory bowel disease (IBD) have more microplastics in their feces than healthy controls, suggesting that the fragments could be related to the disease process.

Application and preparation of expanded graphite

  1. What’s expanded graphite?

Expanded graphite is a porous worm-like substance prepared by intercalation, washing, drying and high-temperature expansion of graphite scales. Expanded graphite can instantly expand in volume by 150~300 times at high temperature, changing from flake to worm-like, so that the structure is loose, porous and curved, the surface area is enlarged, the surface energy is improved, the adsorption force of flake graphite is enhanced, and the worm-like graphite can be self-embedded, which increases its flexibility, resilience and plasticity. Expanded graphite not only retains the excellent properties of graphite such as high temperature resistance, corrosion resistance, radiation resistance, electrical conductivity and thermal conductivity, but also has many unique excellent properties, such as flexibility, resilience, self-adhesion, impermeability, adsorption and low density.

Research News: Pesticide is linked to brain damage

Chlorpyrifos is a dangerous pesticide widely used in the U.S. on staple food crops, such as cornwheat, soy, applecitrus and more. It is also used in recreational spaces like parks.

Chlorpyrifos belongs to a class of pesticides called organophosphates, which were developed as a nerve gas by Nazi GermanySince World War II, organophosphates like chlorpyrifos were repurposed for agriculture.

Research News: How to judge the heavy metals in the water?

The presence of pollutants in aqueous solution, particularly from hazardous heavy metals and metalloids, is an important environmental and social problem. As many of these elements are stable they are bio-accumulative, and assessment of their safe limits is very difficult in the ecosystem. Few metals, such as Fe, Zn, Cu, Co, Cr, Mn and Ni, are required for biological metabolism in trace amounts; however, their higher dose may cause toxic effects. Others, such as Pb, Hg, Cd and As, are not suitable for biological functions and are positively toxic. Toxicity of these elements is of considerable concern worldwide because of their environmental burden. During the past few decades scientists have been developing cheap and environmentally friendly technologies for the treatment of wastewater generated at the household and up to the industrial scale.

Heavy metal hazards in the environment

Heavy metal, which refers to metals with a density of more than 4.5g per cubic centimeter. There are about 45 kinds of heavy metals, including Cu, Pb, Zn, Fe, Co, Ni, Mn,,et al. Where do heavy metal come from in our daily life ? The answer may surprise you: they are everywhere!

Do you know how to degrade dye wastewater ?

Dye wastewater industrial wastewater not only pollutes the environment seriously, but also is difficult to treat. Because the dye is more stable to be decomposed. The dye shows colors because the azo structure, and methyl orange is a typical azo dye with simple structure. Methyl Orange is usually used to simulate dye wastewater. Generally, Methyl Orange is photocatalytic, but the efficiency is very low.

Can essential oil sterilize?

The world aromatherapist society in 2008, in Singapore, Slyvia, a couple of therapists from Columbia, announced that they took 5 years to protect children from AIDS with essential oil in refugee camps. The childrens age covered from a few months to ten years old with both parents dead, and serological AIDS antibody showed positive.

Research News: Blueprint outlined to add in ‘fail-safes’ for science publishing

Two prominent researchers that have frequently written about science’s reproducibility problem have suggested seven key reforms that they say will improve the reliability of scientific publications.

Writing in the Journal of Clinical Investigation, Arturo Casadevall of Johns Hopkins School of Medicine in the US and Ferric Fang of the University of Washington say the reliability of the scientific literature is ‘of the utmost importance to society’. ‘However, in recent years, rising numbers of retracted articles, reproducibility problems and inappropriately duplicated images have increased concern that the scientific literature is unreliable,’ the pair write.

Research News: Molecule undergoes unprecedented topology switch from Möbius aromatic to Hückel anti-aromatic when immersed in polar solvent

Three-component reversible π-system switching between 28π Möbius cross-conjugated, 28π Hückel macrocyclic and 26π Hückel cross-conjugated π-systems by solvent-dependent topological or redox interconversions

Scientists in Japan have developed a system that can switch its topology from being Möbius to Hückel and back again. Not only was this type of reversible switch unexpected, it could also be triggered by external stimuli such as a polar solvent. 

A cyclic molecule is Möbius aromatic if it has [4n]π electrons and anti-aromatic (destabilised) if it has [4n+2]π electrons. The opposite is true of Hückel systems – a system with [4n+2] conjugated electrons is aromatic and a [4n]π electron system is anti-aromatic. Aromaticity brings stability, so you would expect [28]hexaphyrins – having [4n]π electrons – to adopt an aromatic Möbius topology.

Research News: Macrocycles power up carbon nanotubes

Interlocked molecules tune the electronic properties of nanotubes, allowing researchers to control their catalytic activity

Carbon nanotubes are a green alternative to metallic catalysts. However, tuning their activity relies on difficult and invasive chemical processes that normally damage the nanotubes’ structure. Now, only a few years after reporting the first mechanically interlocked nanotube derivatives, Emilio Pérez and his team at the IMDEA Nanoscience Institute in Madrid, Spain, have envisioned how to use these non-covalent modifications to power up the catalytic activity of carbon nanotubes.
