Physics Today Notes NanoLub Engine Oil Additive, As An Example Of Only 10% Of Entries In The CPI, Which Provide …

An article published in Physics Today, the prestigious bulletin of the American Physical Society on February 2014, reviews the worrying situation in the nano-tech market, where some producers make unsubstantiated scientific claims with regards to their products' use of nanotechnology.

According to the article, an extensive review conducted by Nanotechnology Consumer Products Inventory (CPI) reveals that only 10% of the 1600 consumer products listed in the CPI, currently provide appropriate safety data and supporting scientific evidence for their technological claims.

Under the review, each product has received one of 5 possible category tags: Category 5 (Not advertised by manufacturer), Category 4 (Unsupported claim), Category 3 (Manufacturer-supported claim), Category 2 (Verified claim), and Category 1 (Extensively verified claim) which was awarded to only 7 products, 4 of them from NanoMaterials NanoLub product line.

As per CPI standards, the Extensively Verified Claim Category 1 Tag received by NanoLub products is awarded when: The manufacturer has provided information supporting the nanotechnology claim and this claim was verified by an independent source. Actual product has been tested for nanomaterial or supporting documentation references such product or product was described in more than one published scientific documents (such as research studies, patents, or reports). For example: The manufacturer website lists a datasheet with nanomaterial characteristics plus a scientific research paper or patent also describes the product.* (*)The CPI Category 1 Listing can be viewed by clicking here.

Nanolub Oil Engine Additive, one of NanoMaterials products to receive the Extensively Verified Claims tag, is specifically mentioned by Physics Today as a positive example of a scientifically well substantiated product:

according to the CPIs own new data-quality rating - called How much we know- fewer than 10% of the entries currently provide supporting evidence that the nanomaterial works as claimed, or is even present in the product. One that does is an engine-oil additive under the extensively verified claims category, which identifies the nanomaterial (tungsten disulfide nano particle), its function (lubricant), its location in the product (suspended in liquid), and its potential human exposure pathway (dermal absorption and inhalation). The entry also includes quotes from research papers that validate the function and performance claims of the nanomaterial.**

We always welcome and even advocate for such reviews said Daniel Sclar, NanoMaterials CEO. This increased transparency is definitely good for the nanotech industry, as it allows the customer to differentiate between those companies whose products are based on serious scientific research, from those who just use nano as a buzz word. Being noted as an example of a well substantiated product, as in this case, raises our customers' confidence and gives a great feedback to our scientists.

The NanoLub series has received the prestigious Nano 50TM Award by Nanotech Briefs (publishers of NASA Tech Briefs) and it is the first successful commercial implementation of inorganic, multi-layered fullerene-shaped WS2 nanoparticles in lubricants, based on patented and award-winning technology developed at Weizmann Institute of Science.

Graphene Origami Boxes Store Hydrogen Fuel

Posted on by

Researchers at the University of Maryland have demonstrated through computer modeling that graphene can be triggered by an electric field to fold itself into a nifty three-dimensional box that can serve as a container for hydrogen storage and then unfold itself.

The technique could greatly increase a fuel cell's ability to store and release hydrogen -- an advance that could improve the capacity of hydrogen fuel cells for powering cars.

The way in which the graphene folds up into a box has been dubbed hydrogenation-assisted graphene origami (HAGO) and involves cutting the graphene into a pattern and then functionalizing it by atomically attaching hydrogen to the carbon atoms of the graphene. The electric field that is used does not trigger the graphene to perform its origami but is used to unfold the structure and then repeat the trick.

First, a suitably functionalized and patterned graphene can spontaneously fold into a 3-D nanostructure.... No external electric field is needed, explained Teng Li, an associate professor of mechanical engineering at University of Maryland in an e-mail to Nanoclast. Second, an electric field can cause the polarization of the graphene, effectively reducing the graphene inter-layer adhesion, which causes the folded nanostructure to unfold. Upon turning off the electric field, the graphene folds up into a box spontaneously again. Such a process can be repeated many times.

In the research, which was published in the journal ACS Nano(Hydrogenation-Assisted Graphene Origami and Its Application in Programmable Molecular Mass Uptake, Storage, and Release), the graphene origami boxes demonstrated remarkable hydrogen storage capabilities. The researchers calculate that graphene origami boxes have a hydrogen storage capacity of 9.7 percent by weight, far exceeding targets set by the U.S. Department of Energy (DOE) -- 5.5 percent by 2017 and 7.5 percent by 2020.

It would seem that nanomaterials are exceeding DOE targets for fuel cells on a pretty regular basis now. However, nanomaterials have a somewhat checkered past with hydrogen storage. At one time, carbon nanotubes were touted as the next big thing in that field, with claims of greater than 50-percent storage capacity.

But it is now generally accepted that the figure is really closer to 1-percent. The problem was that the structures of both carbon nanotubes and fullerenes did not remain stable. This instability has not proven to be a problem with the HAGO boxes.

Much effort has been dedicated in this research to demonstrate the promising feasibility of the HAGO process, including its robustness to possible manufacturing defects and stability at room temperature, wrote Li. We will actively pursue collaborations with experimentalists to actually demonstrate.
