Curtiss is a specialist in developing quantum chemical methods for accurate energy calculations and applying these methods to energy- and material-related problems, including those related to catalysis, batteries, and carbon materials. His work has been cited over 67,000 times. [2]
Curtiss is a fellow of the American Association for the Advancement of Science. [3]
Curtiss received his bachelor's degree in chemistry from the University of Wisconsin-Madison in 1969. [1] He then attended Carnegie-Mellon University, where he completed his master's in physical chemistry in 1971, and his Ph.D. in physical chemistry in 1973. [1] [4] While a graduate student, he worked under the supervision of pioneering chemist Sir John Anthony Pople, who won the Nobel Prize in chemistry for his work on computational methods in quantum chemistry. [5] Curtiss's thesis focused on quantum chemical studies of hydrogen bonded complexes. After graduating in 1973, he became a research fellow at Battelle Memorial Institute in Columbus, Ohio until 1976. [1] [4]
Curtiss joined Argonne in 1976 as a research associate in Argonne's former Chemical Technology Division, where he rose through the ranks to become senior scientist in 1988. [4] In 1998, Curtiss was appointed to his current position as senior scientist and group leader of the Molecular Materials Group within Argonne's Materials Science Division. [4] From 2006 until 2009, he was also an acting group leader at the Center for Nanoscale Materials, and from 2004 until 2018, Curtiss was a senior fellow of the University of Chicago/Argonne Computation Institute. [4] In 2000, Curtiss was named an Argonne Distinguished Fellow. [3]
Developing and applying computational chemistry methods
Curtiss helped develop the Gaussian-n series of quantum chemical methods for accurate energy calculations (G1, G2, G3, and G4 theories). [6] [7] [8] [9] These methods are for calculating the thermochemical properties of molecules and ions.
Modeling lithium-ion batteries and beyond-lithium-ion batteries
Curtiss is also involved in developing so-called "beyond-lithium-ion" batteries, such as lithium-sulfur and lithium–air batteries. He helped create a Li-O2 battery that runs on lithium superoxide. [10] [11] Curtiss and researchers from Argonne and the University of Illinois also designed a lithium-air battery that works in a natural air environment for over 700 charge and discharge cycles, surpassing previous technology.

Sir John Anthony Pople was a British theoretical chemist who was awarded the Nobel Prize in Chemistry with Walter Kohn in 1998 for his development of computational methods in quantum chemistry.
Gaussian is a general purpose computational chemistry software package initially released in 1970 by John Pople and his research group at Carnegie Mellon University as Gaussian 70. It has been continuously updated since then. The name originates from Pople's use of Gaussian orbitals to speed up molecular electronic structure calculations as opposed to using Slater-type orbitals, a choice made to improve performance on the limited computing capacities of then-current computer hardware for Hartree–Fock calculations. The current version of the program is Gaussian 16. Originally available through the Quantum Chemistry Program Exchange, it was later licensed out of Carnegie Mellon University, and since 1987 has been developed and licensed by Gaussian, Inc.
Q-Chem is a general-purpose electronic structure package featuring a variety of established and new methods implemented using innovative algorithms that enable fast calculations of large systems on various computer architectures, from laptops and regular lab workstations to midsize clusters, HPCC, and cloud computing using density functional and wave-function based approaches. It offers an integrated graphical interface and input generator; a large selection of functionals and correlation methods, including methods for electronically excited states and open-shell systems; solvation models; and wave-function analysis tools. In addition to serving the computational chemistry community, Q-Chem also provides a versatile code development platform.
Møller–Plesset perturbation theory (MP) is one of several quantum chemistry post-Hartree–Fock ab initio methods in the field of computational chemistry. It improves on the Hartree–Fock method by adding electron correlation effects by means of Rayleigh–Schrödinger perturbation theory (RS-PT), usually to second (MP2), third (MP3) or fourth (MP4) order. Its main idea was published as early as 1934 by Christian Møller and Milton S. Plesset.
In computational chemistry, post–Hartree–Fock (post-HF) methods are the set of methods developed to improve on the Hartree–Fock (HF), or self-consistent field (SCF) method. They add electron correlation which is a more accurate way of including the repulsions between electrons than in the Hartree–Fock method where repulsions are only averaged.
In chemistry, triiodide usually refers to the triiodide ion, I−
3. This anion, one of the polyhalogen ions, is composed of three iodine atoms. It is formed by combining aqueous solutions of iodide salts and iodine. Some salts of the anion have been isolated, including thallium(I) triiodide (Tl+[I3]−) and ammonium triiodide ([NH4]+[I3]−). Triiodide is observed to be a red colour in solution.
INDO stands for Intermediate Neglect of Differential Overlap. It is a semi-empirical quantum chemistry method that is a development of the complete neglect of differential overlap (CNDO/2) method introduced by John Pople. Like CNDO/2 it uses zero-differential overlap for the two-electron integrals but not for integrals that are over orbitals centered on the same atom.
Spartan is a molecular modelling and computational chemistry application from Wavefunction. It contains code for molecular mechanics, semi-empirical methods, ab initio models, density functional models, post-Hartree–Fock models, and thermochemical recipes including G3(MP2) and T1. Quantum chemistry calculations in Spartan are powered by Q-Chem.
Semi-empirical quantum chemistry methods are based on the Hartree–Fock formalism, but make many approximations and obtain some parameters from empirical data. They are very important in computational chemistry for treating large molecules where the full Hartree–Fock method without the approximations is too expensive. The use of empirical parameters appears to allow some inclusion of electron correlation effects into the methods.

Lithium superoxide is an unstable inorganic salt with formula LiO2. A radical compound, it can be produced at low temperature in matrix isolation experiments, or in certain nonpolar, non-protic solvents. Lithium superoxide is also a transient species during the reduction of oxygen in a lithium–air galvanic cell, and serves as a main constraint on possible solvents for such a battery. For this reason, it has been investigated thoroughly using a variety of methods, both theoretical and spectroscopic.
Quantum chemistry composite methods are computational chemistry methods that aim for high accuracy by combining the results of several calculations. They combine methods with a high level of theory and a small basis set with methods that employ lower levels of theory with larger basis sets. They are commonly used to calculate thermodynamic quantities such as enthalpies of formation, atomization energies, ionization energies and electron affinities. They aim for chemical accuracy which is usually defined as within 1 kcal/mol of the experimental value. The first systematic model chemistry of this type with broad applicability was called Gaussian-1 (G1) introduced by John Pople. This was quickly replaced by the Gaussian-2 (G2) which has been used extensively. The Gaussian-3 (G3) was introduced later.
Louis Edward Brus is an American chemist, and currently the Samuel Latham Mitchell Professor of Chemistry at Columbia University. He is the co-discoverer of the colloidal semi-conductor nanocrystals known as quantum dots. In 2023, he was awarded the Nobel Prize in Chemistry.
The lithium–air battery (Li–air) is a metal–air electrochemical cell or battery chemistry that uses oxidation of lithium at the anode and reduction of oxygen at the cathode to induce a current flow.
A metal–air electrochemical cell is an electrochemical cell that uses an anode made from pure metal and an external cathode of ambient air, typically with an aqueous or aprotic electrolyte.
Michael Makepeace Thackeray is a South African chemist and battery materials researcher. He is mainly known for his work on electrochemically active cathode materials. In the mid-1980s he co-discovered the manganese oxide spinel family of cathodes for lithium ion batteries while working in the lab of John Goodenough at the University of Oxford. In 1998, while at Argonne National Laboratory, he led a team that first reported the NMC cathode technology. Patent protection around the concept and materials were first issued in 2005 to Argonne National Laboratory to a team with Thackeray, Khalil Amine, Jaekook Kim, and Christopher Johnson. The reported invention is now widely used in consumer electronics and electric vehicles.
