Adam Heller received his M.Sc. (Chemistry and Physics, 1957) and Ph.D. (Chemistry, 1961) from the Hebrew University, Jerusalem, where he studied under E. D. Bergmann.  Following postdoctoral work at U.C. Berkeley and at Bell Laboratories, he joined GTE Laboratories becoming Manager of Exploratory Research in 1970.  In 1975 he returned to ATT Bell Laboratories, heading from 1977 until 1988 the Electronic Materials Research Department. He managed the early phase of the development of the materials science and engineering of the now practiced high-density chip interconnections. He was appointed to the Ernest Cockrell, Sr. Chair in Engineering at The University of Texas at Austin in 1988 and became one of the first Research Professors of the University of Texas in 2002.

Heller’s contributions to science are described in 225 peer reviewed papers and his contributions to technology in 85 issued US patents. 

His studies of radiationless relaxations led him to propose that, in absence of energy transfer to high frequency vibrations associated with bonds of hydrogen atoms, the excited ions decay only radiatively. Based on this proposal, he built the first inorganic liquid lasers, which were solutions of neodymium salts in liquid inorganic oxyhalides (Appl. Phys. Lett., 9, 106 (1966); Physics Today, 20(11), 35, (1967)). After recognizing that neither sodium nor lithium corrode in the inorganic oxyhalides, he designed, with James J. Auborn, the lithium thionyl chloride battery (J. Electrochem. Soc. 120, 1613 (1973)), which remains, after more than 30 years, widely used. It   powers, for example, neurostimulators alleviating chronic pain, treating epilepsy and Parkinson’s disease, powering implanted drug-infusion devices for treatment of cancer, cerebral palsy, chronic pain and management of diabetes. The battery is also widely used in defense applications.

In his studies of solar energy conversion, Heller demonstrated that photo-electrochemical cells can convert efficiently sunlight to electrical power and to chemical energy, stored as hydrogen. He raised the solar conversion efficiency of these cells by  an order of magnitude, to > 10 %.  (Nature, 262, 680 (1976); Science, 196, 1097 (1977); Appl. Phys. Lett. 33, 521 (1978);  J. Electrochem. Soc. 126, 954 (1979);  J. Am. Chem. Soc., 102, 6555 (1980);  J. Am. Chem. Soc.  102, 1877 (1980);  Appl. Phys. Lett. 38, 282 (1981);  Phys. Rev. Letters, 46, 1153, (1981); J.  Am. Chem. Soc.  104, 6942 (1982); Science, 223, 1141 (1984)). His studies, with the late Heinz Gerischer, of the role of oxygen in the photocatalytic oxidation of organic compounds on titanium dioxide, (J. Phys. Chem. 95, 5261 (1991); J. Phys. Chem. 99, 5633 (1995)), defined that the controlling step is oxygen-reduction by the photogenerated electrons, not the oxidation of the organic compounds by the photogenerated holes.    Heller applied this knowledge in photocatalysts for the oxidation of thin organic films (Acc. Chem. Res. 28, 503 (1995)), particularly on window glass (J. Mater. Res. 10, 2842  (1995)), now widely used in “self cleaning” windows, made by major window-glass manufacturers like PPG Industries in the US, Saint-Gobain in France and Pilkington in the UK.

Heller then showed that reaction centers of electron transferring enzymes can be electrically “wired” to electrodes through bound electron-relaying redox centers and applied this knowledge to the design of  miniature biosensors and biofuel cells. (J. Phys. Chem.  91, 1285 (1987); J.  Am. Chem. Soc. 110 , 2615 (1988); J.  Am. Chem. Soc.  111, 2357 (1989); J. Phys. Chem.  95, 5970 (1991); J. Phys. Chem. 95 5976 (1991); Anal. Chem. 66, 2451 (1994). He co-founded, with his son Ephraim Heller, Therasense, Inc., building electrochemical glucose monitors, improving the lives of diabetic people. 

The measurement of the blood glucose concentration by self-monitoring diabetic people has been and remains the most frequently performed chemical analysis, performed 6 billion times each year,  more often than all other analyses combined.  With Ben Feldman and Ephraim he designed a thin-layer micro-coulometer FreeStyle™, which required only 300 nL blood, so little that, for the first time, it was painlessly obtained (Diabetes Technology & Therapy 2, 221 (2000)).  Its cell of is the smallest mass manufactured fluidic device. Heller also designed a continuous, miniature, subcutaneously implanted glucose monitor based on the electrical “wiring” of glucose oxidase. (Anal.Chem. 67, 1326-1331 (1995); Proc. Nat. Acad. of Sci., 95, 6379-6382 (1998); Proc. Nat. Acad. Sci., 95, 294-299 (1998)). In 2004 TheraSense completed clinical trials of the continuous monitor, FreeStyle Navigator, scheduled for release in 2005.

 Abbott Laboratories acquired TheraSense in 2004  for $ 1.2 billion, moving the headquarters of Abbott Diabetes Care to the Alameda, CA site of TheraSense.   

Presently Heller and his colleagues are designing miniature oxygen-reducing glucose-oxidizing membrane-less biofuel cells that might be used for powering implanted medical sensor-transmitters.  The cells are about a thousand times smaller than the smallest available batteries. They consist of two 7 μm diameter carbon fibers, one coated with a glucose electro-oxidation catalyzing “wired” enzyme, the other with an oxygen electroreduction catalyzing enzyme.  (J. Am. Chem. Soc. 125, 6588 (2003)). The cathode electrocatalyst is superior to platinum and its alloys, which was considered as the best catalyst for the reduction of oxygen to water (J. Am. Chem. Soc., 126, 8368 (2004))

Heller received the Battery Research Award of The Electrochemical Society (1978); was named Guest Professor of the Collège de France (1982);  received the David C. Grahame Physical Electrochemistry Award of The Electrochemical Society (1987);   was elected to the U.S. National Academy of Engineering in 1987;  received the Vittorio De Nora Gold Medal of The Electrochemical Society in 1988;  was awarded the title of Doctor honoris causa of Uppsala University in Sweden in 1991;  received the Medal of the Faculty of Engineering of Tokyo University in 1992; received the Chemistry of Materials Award of the American Chemical Society,  and was named Fellow of The Electrochemical Society in 1994;  received the Michael Faraday (Physical Chemistry) Silver Medal of the Royal Society of Chemistry, UK in 1996; was named Fellow of the American Association for the Advancement of Science in 1997; received  the Spiers Medal of the Royal Society of Chemistry (UK) in 2000; received the Charles N. Reilly Award of the Electroanalytical Society and delivered the Institute Lecture of the American Institute of Chemical Engineers in 2004; and received the Fresenius Gold Medal and Prize of the Gesellschaft Deutscher Chemiker  in 2005.
