Researchers from Monash University (Melbourne, Australia; have discovered that graphene-oxide sheets can change their structure and become liquid droplets spontaneously. Because graphene droplets change their structure in response to an applied magnetic field, they could be used for controlled drug release, says lead researcher, Mainak Majumder. Usually...

The effective removal of Cs+ ions from contaminated groundwater, seawater, and radioactive nuclear waste is crucial for public health and for the operation of nuclear power plants. Although several methods for the removal of Cs+ ions have been developed, there is still a need for better methods. Now a team of Korean researchers led by professor Kyung Byung Yoon from the Dept. of Chemistry, Sogang...
August 1, 2014
A Korean team has developed a carbon material that is as effective as graphene in applications, such as solar cells and semiconductor chips, using a process that requires only two steps instead of the usual eight. High-quality graphene is usually manufactured using chemical vapor deposition (CVD). In this method the graphene is manufactured on the board of a metal film that serves as a catalyst. The...

Separation of micron-sized oil droplets from water is difficult by conventional methods. A Chinese team has developed an oleophilic array of conical needle structures that can continuously collect micron-sized oil droplets from an oil-water mixture with high efficiency and high throughput. The team includes staff from the Institute of Chemistry of the Chinese Academy of Sciences, Dept. of Chemistry at...
April 1, 2014
A new kind of highly flexible and non-flammable inorganic paper that can be used for the permanent and safe storage of information has been developed by a team led by professor Ying-Jie Zhu, from the Shanghai Institute of Ceramics, Chinese Academy of Sciences ( The work has been described in a recent issue of Chemistry — A European Journal. The team developed the paper, which is made...
March 1, 2014
Researchers from Curtin University’s Fuels and Energy Technology Institute (Perth, Western Australia;, led by professors Gordon Parkinson and Chun-Zhu Li, have won the Mitsubishi Corp. Western Australia Innovator of the Year award for creating a new membrane that speeds up the transfer of oxygen. Currently, industrial oxygen production relies on a cryogenic process, which requires...
November 1, 2013
An international team of researchers claims to have developed carbon nanotube (CNT) membranes with an ultrahigh specific-adsorption capacity for salt that is two orders of magnitude higher than that found in current activated-carbon-based water-treatment systems. The team includes researchers from Singapore University of Technology and Design (, CSIRO’s Materials Science and...
November 1, 2013
Researchers from the Australian National University (ANU; Canberra;, and the University of New South Wales (Sydney, Australia; claim to have obtained a temperature- and frequency-independent colossal permittivity (CP) material with a low dielectric loss, making it strikingly superior to typical existing CP materials. “We believe this work breaks through the logjam...

Iron ore is traditionally pelletized using the binding agent bentonite to facilitate transport and handling. A new additive for pelletizing iron ore significantly reduces the volume of binding agent required, while improving pellet strength and production output. Developed by Clariant AG (Muttenz, Switzerland;, the pelletizing additive is a patented polymer-based binding agent that can...

Cement manufacturing is a major source of greenhouse gas emissions due to two factors: carbon dioxide is released when calcium carbonate calcines to lime (CaO) in the cement manufacturing process; and cement kilns are operated at temperatures of 1,500°C, which requires significant fuel consumption. Cement is the agent that binds sand and crushed rock together to form concrete. Solidia Technologies...
July 1, 2013
A process that uses magnetic nanoparticles, coated with a reactive material, to clean up contaminated water for human use is being developed at Stanford University (Stanford, Calif.; The nanoscavengers, as they are called, are distributed in the water to kill pollutants, then are recovered magnetically for re-use. Stanford’s particles are...
July 1, 2013
Freestanding nanowires exhibit ultrahigh elastic-strain limits (of up to 7%) and yield strengths. However, it has been difficult to exploit their properties in bulk composites, due to the mismatch between the elasticity of the nanowires and the elasticity of the metals that form the matrix. The nanowires will experience an elastic deformation of several percent, but normally the metals that form the matrix...
June 1, 2013
Seiko PMC Corp. (Tokyo; has installed a pilot plant for the production of cellulose nanofibers (CNFs) at its Ryugasaki Factory, and will begin shipping samples next spring with the aim of commercial activities in 2015. In...
June 1, 2013
Nippon Paper Industries Co. (Nippon Paper; Tokyo; is constructing a verification plant for the production of cellulose nanofibers (CNFs) at the Chemical Div. of its Iwakuni...
June 1, 2013
Oji Holdings Corp. (OJI; and Mitsubishi Chemical Corp. (MCC; both Tokyo, Japan; have developed a continuous process for producing transparent sheets made from ultra-thin, wood-based cellulose nanofibers (CNF). Both OJI’s papermaking technology and MCC’s chemical treatment technology...
May 1, 2013
Although several antimicrobial hydrogels have been developed in recent years, they all have one or more drawbacks, such as possible toxicity, insufficient stability and biodegradability, and high costs. These and other drawbacks have been overcome with a synthetic hydrogel being developed by researchers from the Institute of Bioengineering and Nanotechnology (Singapore; and IBM...
April 1, 2013
A process developed by researchers at the University of Texas at Arlington ( uses copper-based semiconductor nanoscale-rod arrays and solar radiation to carry out a photoelectroreduction of carbon dioxide to methanol. The process offers a pathway to utilize the greenhouse gas CO2 as a feedstock to synthesize a widely manufactured chemical...

Detection of extremely small quantities of dangerous or hazardous substances is important in many areas, including national security, safety of public utilities and radiation prevention. Several analytical methods have been developed using structural, functional and electronic properties of nanomaterials. In particular, noble-metal quantum clusters (QCs), a family of nanomolecules exhibiting intense...
April 1, 2013
A new and inexpensive way to produce TiFe — an alloy with potential as a material for reversibly storing hydrogen — has been developed by the research groups of professors Zenji Horita and Etsuo Akiba at Kyushu University (Fukuoka, Japan; The TiFe is made by a technique known...
