Chemicals induce dipoles to damp plasmons

| March 22, 2019

The light scattered by plasmonic nanoparticles is useful, but some of it gets lost at the surface and scientists are now starting to figure out why. In novel experiments at Rice University and the Johannes Gutenberg University of Mainz, along with theoretical work at Princeton University, researchers found that molecules placed on the surface of a single gold nanorod affect its plasmonic response by altering the electronic structure of the particle itself The finding could enhance applications like catalysis that involve plasmon-driven chemistry.

How Chemical Companies Benefit from the Experience Economy

Article | February 10, 2020

To feel or experience from a business engagement started with customer experience mainly in the consumer products business. Today it has extended to even knowledge industries like the chemical industry where experiencing or feeling can be leveraged to include all stake holders from customers primarily to employees to supply chain people & suppliers and all else. With digital technologies this has become easier than before. The benefits from promoting the ‘feel’ or ‘experience’ emotion could be multifarious for the chemical industry as described in this article.

Southeast polyolefins demand growth could be negative again in 2021

Article | February 10, 2020

BEFORE the pandemic, GDP growth rates in the developing world were always higher than in developed economies.And because developing economies had much lower levels of petrochemicals consumption than their rich counterparts, it meant that the multiples over GDP were higher than in the rich word, where consumption was pretty much saturated. For instance, polyethylene (PE) demand in a developed country such as Germany might have grown at 0.3% times GDP whereas in Indonesia the growth could have been one or more times higher than the rate of growth in GDP.But as The Economist wrote in this 11 July article: “In 2021 the poorest countries, which are desperately short of vaccines, are forecast to grow more slowly than rich countries for only the third time in 25 years.” Might the multiples over GDP growth also be adversely affected in the developing world, trending lower than the historic norms? They will almost certainly remain higher than the rich countries. But here is the thing: as millions more people are pushed back into extreme poverty by the pandemic or are denied the opportunity to achieve middle-income status, I believe that developing-world multiples may well decline.Escaping extreme poverty means being able to, say, afford a whole bottle of shampoo for the first time rather than a single-serve sachet, thereby raising per capita polymers consumption.

When chemistry becomes intelligent

Article | February 10, 2020

Nowadays, artificial intelligence (AI) and computer programs have infiltrated almost every corner of our lives; from facial recognition, language translation, image and video production, to self-driving cars and personal care aides. Other applications that might not yet be mainstream knowledge have to do with scientific exploration and research and development. For example, AI has the potential to revolutionize medical practices through augmenting medical diagnosis and have found application in drug discovery. In many places, researchers have also attempted to use AI algorithms to manipulate biology, chemistry, and physics with different setup configurations that can detect DNA modifications caused during epigenetic regulation or gene mutation, choose the most optimal reaction pathways in synthesis, and search for exotic particles using adapted learning networks.

Organic Oil Recovery improves productivity of existing reservoirs

Article | February 10, 2020

MAY 2021 ///Vol 242 No. 5 FEATURES Organic Oil Recovery improves productivity of existing reservoirs A transitional technology producing excellent results in extracting hard-to-reach oil is attracting the attention of many large operators. Ancient, resident microbes are used to liberate large oil deposits in depleted reservoirs, thanks to science uncovered by studying the humble Australian koala. Roger Findlay, Organic Oil Recovery It began in almost outlandish fashion, with a scientist’s fascination with the complex digestive system of an Australian marsupial, the koala. Today, it has evolved into a green technology that is helping major producers around the world potentially reach billions of dollars of oil that they feared they could never access or bring to the surface. As the pressure on the oil and gas industry continues to grow, to find new ways to operate with less impact on the environment, Organic Oil Recovery (OOR) is reducing the need for further exploration. Instead, it is helping producers focus on the reservoirs already in situ to extract even more precious resource—at very low cost—from deep below the ground or seas, across a myriad of jurisdictions and geographies.
