Steve Feller: a life in borates
Mario Affatigato, Physics Department and Center for the Study of Glass, Coe College, Cedar Rapids, Iowa, USA
Professor Steve Feller has made a number of significant contributions to the understanding of the structure and properties of borate glasses, starting from his work in graduate school. This article provides an overview of his life and career, showing the context for his scientific work. Decades-long collaborations that had a significant impact on the borate work are highlighted, and his development of a nationally-recognised undergraduate research program in glass is also detailed. Finally, family events and scientific awards are included.

A 44 Year Search: How do the fundamental physical properties of borate glass reveal its underlying atomic structure: an adventure with undergraduates
Steve Feller, Physics Department, Coe College, Cedar Rapids, USA
In this career review article, I have gone over several key accomplishments that span nearly half a century. The review is divided between my work done at Brown University, as a graduate student (1973–1979), and work done with hundreds of undergraduate physics students at Coe College, as well as with dozens of collaborators around the world (1979–2017). Several important aspects of the work are discussed, including how it was possible to work productively with undergraduates over a large number of years. Also, this paper includes selected student outcomes, and a comprehensive list of collaborators and funding sources.

On the connectivity of borate tetrahedra in borate and borosilicate glasses
Doris Möncke, Gregory Tricot, Anja Winterstein-Beckmann, Lothar Wondraczek & Efstratios I. Kamitsos
In borosilicate glasses, not only the question of the fraction of four- and three-fold coordinated boron deserves special consideration, but also the connectivity of the tetrahedral and trigonal borate groups with each other and with the silicate network. Older structural studies and models of borate and borosilicate glasses often invoke an avoidance rule in the context that negatively charged borate tetrahedra will not be directly linked in glasses. This statement is analogous to the Loewenstein rule which was postulated for aluminate tetrahedra in zeolites. For these low alkaline glasses, B4–O–Si links are formed in quenched glasses but tend to disappear after annealing, whereas the remaining connections between the borate and silicate sub-networks involve predominantly B3–O–Si linkages.

Glass thermodynamics: Clausius theorem and a new tensorial definition of temperature
Akira Takada, Reinhard Conradt & Pascal Richet
This paper aims at unifying the statistical mechanics and thermodynamics of glass through a new extended definition of temperature. Along with new insights into the Clausius theorem, this definition has been derived from a three-level model system. As previously shown in our study of a two-level system, introduction of an additional parameter, i.e. an internal temperature, is useful to describe the relation between energy and entropy changes in non-equilibrium states. This study introduces a more general definition of the zeroth law of thermodynamics for non-equilibrium conditions, and extends the concept of fictive temperature as an order parameter to distinguish non-equilibrium glasses.

Optical absorption of 3d transition metal and rare earth elements in zirconium fluoride glasses
Y. Ohishi, S. Mitachi, T. Kanamori & T. Manabe
Nippon Telegraph and Telephone Public Corporation, Japan
Absorption spectra of 3d transition metal and rare earth elements in zirconium fluoride glasses were measured and their absorptivities in the near to mid infrared range have been evaluated. The absorptivities of Fe, Co, Ni, and Cu are, respectively, 90, 130, 90, and 3 dB/km/ppm at the 2 µm band; their effective absorption is low above 3 μm. Rare earth elements such as Ce, Pr, Nd, Sm, Eu, Tb, and Dy have sharp absorption bands in the 2 to 5 μm range and their peak absorptivity is between 1 and 100 dB/km/ppm. In order to obtain a fluoride glass fibre with a transmission loss of less than 0·1 dB/km at 2·5 μm, the Fe, Co, or Nd content should be less than 1 ppb and the Ni, Pr, Sm, or Eu content should be less than 10 ppb.

The 2024 AGC–Michael Cable Memorial Lecture: Progress and challenges in decarbonization of industrial glass melting
Manoj K. Choudhary, The Ohio State University, Columbus, Ohio, USA
Achieving net-zero carbon emissions by 2050 to limit global warming to 1·5°C is one of humanity’s most critical challenges. Every energy-intensive sector, including glass manufacturing, must play a part in reaching this goal. This paper, based on the AGC/Professor Michael Cable Memorial Lecture, presents a comprehensive analysis of the technical challenges and strategies for decarbonization of glass melting, the most energy-intensive process in glass production, accounting for 50–80% of the total energy used in glass manufacturing.

How glassmakers and scientists learnt about ‘new’ glasses 350 years ago
Colin Brain
Glass Technology - European Journal of Glass Science and Technology Part A, Volume 65, Number 4, August 2024, pp. 116-122(7)
On 6th October 1672 the group of diners at Lord Salisbury’s table included Robert Hooke, the Royal Society’s curator of experiments. He noted in his diary ‘Discoursd after dinner of new glasses...’. This interest in innovative glasses was not an isolated or transient one. The previous year Robert Boyle had argued that it was important that ‘curious people’ should understand ‘trades’: ‘It [experimental philosophy] may enable gentlemen and scholars to converse with tradesmen and benefit themselves (and perhaps the tradesmen too) by that conversation; or at least it will qualify them to ask questions of men that converse with things, and sometimes to exchange experiments with them.’ So began the glass industrial revolution.

Commercial glass strengthening and safety technologies: lessons learned and yet to be learned
Guglielmo Macrelli(1), Arun K. Varshneya(2), Stefan Karlsson(3) & John C. Mauro(4)
1-Isoclima
2-Saxon Glass Technologies
3-RISE Research Institutes of Sweden
4-The Pennsylvania State University
This is the fourth in this series of “Lessons Learned and Yet to be Learned” on topics related to glass strength. In this paper we pick up the topic of stronger glass products from our earlier publication and expand to discussing commercial technologies. Included in this discussion are a brief historical perspective of the initial technologies and update to newer technologies with the aim to obtain faster production rates that focus on lightweight glass products and a sustainable future with respect to resource conservation, reduced energy consumption and reduced CO2 emissions. Also included are glass products which focus on safety mostly and less on overall strength.
