Novel platform purifies oil-contaminated seawater

The approach has implications for improving water scarcity around the world, researchers say

28-Mar-2022 - The United Nations’ most recent Intergovernmental Panel on Climate Change reportpaints a bleak picture for the world’s water supply: Of the 7.8 billion people on Earth, about 4 billion do not have access to sufficiently clean water for at least a month every year. While several water ...

Creating invisibility with superconducting materials

Invisibility devices may soon no longer be the stuff of science fiction

23-Dec-2021 - A new study published in the De Gruyter journal Nanophotonics by lead authors Huanyang Chen at Xiamen University, China, and Qiaoliang Bao, suggests the use of the material Molybdenum Trioxide (α-MoO3) to replace expensive and difficult to produce metamaterials in the emerging technology of novel ...

Probing molecular orientation by polarization-selective transient absorption spectroscopy

07-Sep-2021 - The organic solar cell (OSC) heterojunction interface is where key photophysical processes such as charge separation and recombination occur. The molecular orientation at the interface is one of the key factors that determine the efficiency of solar cells. Due to the complex three-dimensional ...

Electroreduction of carbon monoxide for the highly selective production of ethylene

13-Dec-2019 - Ethylene, or ethene, is a primary feedstock for the chemical industry, including as a starting material for the production of a wide variety of plastics. In the journal Angewandte Chemie, scientists have now introduced a new electrochemical technique for selective and energy-efficient production ...

Researchers have discovered how a nanocatalyst works at the atomic level

31-May-2019 - The researchers of the Nanoscience Center (NSC) at the University of Jyväskylä, Finland, and in the Xiamen University, China, have discovered how copper particles at the nanometre scale operate in modifying a carbon-oxygen bond when ketone molecules turn into alcohol molecules. Modification of ...

Finding Chemicals inside a Cell

Chemical and topographical single-cell imaging at nanoscale resolution by near-field desorption mass spectrometry

08-Feb-2019 - How are chemicals distributed in a cell? Chinese scientists have developed a combined mass spectrometry and biological imaging device that enables direct, label-free detection, and high-resolution mapping of chemicals inside a biological cell. As demonstrated in their publication in the journal ...

Making nail polish while powering fuel cells

05-Aug-2016 - Hydrogen is widely regarded as a promising and clean alternative energy source. The traditional source of hydrogen (H2) for fuel cell use is water, which is split into H2 and oxygen (O2). But O2 is a low-value product. So, this week in ACS Central Science, researchers report a new approach and a ...

New guideline for synthesis of fullerene electron acceptors

29-Jan-2016 - Organic/polymer solar cells represent the most important direction for green energy in the future. Fullerene electron acceptors have been widely used in organic/polymer solar cells as well as perovskite solar cells. A recent study reveals that the photovoltaic performance can be influenced by ...
