Technology

Acoustic microscopy employs very high or ultrahigh frequency ultrasound. Acoustic microscopes operate non-destructively and penetrate most solid materials to make visible images of internal features, including defects such as cracks, delamination and voids.

The notion of acoustic microscopy dates back to 1936 when S.

Ya. Sokolov proposed a device for producing magnified views of structure with 3-GHz sound waves. However, due to technological limitations at the time, no such instrument could be constructed, and it was not until 1959 that Dunn and Fry performed the first acoustic microscopy experiments, though not at very high frequencies. Today, Acoustography is a broad-area, near real-time ultrasonic imaging technique that provides an alternative to point- by-point UT.

Innovation

Acoustography differs from conventional ultrasonic testing in that test objects are inspected in full field, analogously to real time

(14)

x-ray imaging. The approach uses a novel, super high resolution large area acousto-optic (AO) sensor, which allows image formation through simple ultrasound shadow casting, analogous to x-ray image formation. This NDE approach offers significant inspection speed advantage over conventional point-by-point ultrasonic scanning procedures and is well-suited for high volume production. ACOUSTOGRAPHY developed by Dr Sandu is an ultrasound imaging method where a novel, super high-resolution 2D ultrasound detector (AO sensor) is used to produce instant x-ray-like ultrasound images.

The basic components needed to perform Acoustography NDE are:

1) AO-Sensor (Imaging Screen); 2) Wand Transducer (ultrasound emitter); 3) Optical imager Detector. The Wand Transducer is swept across the part held over the AO sensor to form instant x-ray like ultrasound images of the part revealing anomalies in the test part.

The image formed on the AO sensor is viewed and digitally recorded using the Optical Imager.

The company offers ACOUSTOGRAPHY NDE as a standalone system, or as an add-on ACOUSTOGRAPHY NDE capability to existing C-scan systems. The small Table-Top system is perfect for the NDE

(15)

of composite parts and for providing near real-time monitoring of damage growth in coupons subject to load. And retrofit system package is perfect for providing add-on Acoustography NDE capability to customers with existing C-scan systems. Further fully- automated systems are perfect for the manufacturing floor, capable of enhancing inspection throughput by up to 10 times. In addition, ACOUSTOGRAPHY components can also be purchased, along with data electronics and software package, by customers desiring to build their own systems or wanting to retrofit components to have add-on ACOUSTOGRAPHY NDE capability to their C-scan systems.

He then started his career as a postdoctoral researcher in the University of Ulster (2000-01) with subsequent roles as a research Scientist at the Brookhaven National Laboratory, New York, USA (2001-02), an academic and enterprise researcher at Teesside University (2003-2018) and University of Portsmouth (2018 – 2020). Dr Rahman is now a Senior Lecturer at Liverpool John Moores University and Founder of TeeGene & TARA Biologics.

He has 25 years of academic experience in research, innovation, management, and commercialization. He has discovered novel bio surfactant producing bacteria and is the author of 70+ peer- reviewed journal articles and editor of three books on the topic of

(17)

Bio surfactants. He is a winner of Teesside University’s Enterprise Project of the year award.

https://www.linkedin.com/in/prahman/

Technology

Biosurfactants refers to surfactants from microbial origin and can be synthesized by several identified microorganisms including bacteria, yeast and fungi. They display excellent surface activity and emulsification properties with very low toxicity and higher biodegradability features as compared to chemical counterparts.

They have also been found to be very effective at low concentrations and over a wide range of environmental conditions such as pH, temperature and salinity; better environmental compatibility, lower critical micelle concentration, higher selectivity, specific activity and the ability to be synthesized from renewable low cost resources.

There are five major categories of bio surfactants viz. glycolipids, phospholipids and fatty acids, lipopeptides and lipoproteins.

Polymeric biosurfactants, particulate biosurfactants have found applications in agricultural, pharmaceutical, food, cosmetics, and detergent industries.

Innovation

Among the various categories of biosurfactants the glycolipid biosurfactants “rhamnolipids” stand apart. Rhamnolipids are highly applicable in various activities with some researchers advancing the technology from laboratory to higher scale. However, there still are very limited companies in the field which are producing biosurfactants at a marketable scale. TeeGene Biotech produces Rhamnolipids and Lipopeptides for Pharmaceuticals, cosmetics, antimicrobials and anti-cancer ingredients.

(18)

Patents

In 1984, the first patent for the production of rhamnolipids was filed by Kaeppeli and Guerra-Santos (US 4628030) and obtained in 1986 for their work on Pseudomonas aeruginosa DSM 2659.

Subsequently, Wagner et al. filed a patent (US 4814272) in 1985 for the biotechnical production of rhamnolipids from Pseudomonas sp. DSM 2874 and obtained the same in 1989.

Commercialisation

In 2013, the European Commission launched Bio Base NWE, a three-year and €6,2 million project to support the development of the biobased economy in North West Europe (NWE). Bio Base NWE successfully implemented an Innovation Coupon Scheme. A coupon represented a value of maximum €30.000 for feasibility studies and scale-up work undertaken at the Bio Base Europe Pilot Plant (BBEPP), an independent, flexible, state-of–the-art demonstration facility in Ghent, Belgium, to validate innovative biobased technologies and scale them up to an industrial level.

TeeGene Biotech Ltd. (UK), a Teesside University spin-out venture, received a coupon to conduct feasibility studies to prove the technology platform. With insights from experts at Bio Base Europe Pilot Plant the biosurfactant scale-up work was successful, and the startup can manufacture biosurfactants at an industrial level.

Singh Valia, USA

Dr. Harshan Singh Valia received his Masters in Applied Geology from Nagpur University and Masters in Geology from Bryn Mawr College and Ph.D.in Geology from Boston University. Dr. Valia has published 85 articles, contributed to 5 books (including Making, Shaping, and Treating of Steel), chaired 30 National/International conferences, taught 20 courses worldwide, authored two patents, consulted to many industries around the world (especially extensively in China), and presently is a contributor to American Iron & Steel Institute’s web site www.steel.org under How Steel is Made?

(20)

He is the First Ever Indian and Second Ever Asian person to receive Iron & Steel Society’s Joseph Becker Award in 1991 (for distinguished achievement in Coal Technology) for his work on Coal Usage in Steel Industry. Dr. Valia was awarded Joseph Kapitan Award in 2006 (best paper) from the Association for Iron & Steel Technology on his work regarding unique properties of Indiana coals. He is also a recipient of the American Iron & Institute President’s Medal in 1990. These honors have brought him the distinction of the only Coal Scientist in the world to have received all the three awards offered by American Steel Industry related organizations.

Research

He entered the industrial world in 1979 as a research engineer at Inland Steel Co.’s research and development laboratories, East Chicago, Ind., USA. His initial work began with improving blast furnace performance/operation by finding ways to improve Coke Strength after Reaction (CSR) with CO2, which resulted in the development of a CSR predictive model. The model is successfully used to predict CSR from coal properties and helped increase CSR that resulted in performance and operation improvements at No. 7 blast furnace. During his career, Valia worked on a wide range of projects: coke behavior in the blast furnace utilizing blast furnace tuyere sampling; modification of Chinese beehive cokes for blast furnace usability; coal selection and blend design for heat recovery/non-recovery and slot oven coke making; research on carbonization behavior of coal in heat recovery/non-recovery and slot oven coke making; use of poor-quality (low-rank) coals in coke making; prediction of coking quality of coal reserves;

effect of oxidation on coke quality; new coke making technologies;

coal selection and coal behavior in blast furnace pulverized coal injection; and the use of additives in coke making, ironmaking and

(21)

Patents

Utilizing certain unique properties of Indiana coals, Dr. Valia, in collaboration with Allen Ellis and other scientists from Purdue University, earned a patent entitled “Multipurpose Coke Plant for Synthetic Fuel Production.” Such a process would result in not only production of coke for the steel industry but can also produce diesel oil, methane gas, hydrogen, fertilizer, and power.
