  1. Identical or Distinct? The Paneth–Fajans Debate on the Nature of Isotopes.Pieter Thyssen - manuscript
  2. A generalized patchwork approach to scientific concepts.Philipp Haueis - forthcoming - British Journal for the Philosophy of Science.
    Polysemous concepts with multiple related meanings pervade natural languages, yet some philosophers argue that we should eliminate them to avoid miscommunication and pointless debates in scientific discourse. This paper defends the legitimacy of polysemous concepts in science against this eliminativist challenge. My approach analyses such concepts as patchworks with multiple scale-dependent, technique-involving, domain-specific and property-targeting uses (patches). I demonstrate the generality of my approach by applying it to "hardness" in materials science, "homology" in evolutionary biology, "gold" in chemistry and "cortical (...)

  3. From the Atom to Living Systems: A Chemical and Philosophical Journey Into Modern and Contemporary Science.Marina Paola Banchetti-Robino & Giovanni Villani - 2023 - New York, NY: Oxford University Press.
    This book represents an original journey beginning from the simple and undifferentiated atom, to differentiated atoms, to molecules, to macromolecules, and to the thresholds of life. One of the most important aims of this book is to underline the philosophical function of the concept of molecule. The description of the material world permitted by the concept of structured entity has revolutionized the entire scientific worldview. Moreover, the concept of macromolecule has projected the molecular world towards the threshold of the biological (...)

    Plastic waste is a significant environmental problem for almost all countries; therefore, protecting the environment from the problem is crucial. The most sensible solution to these problems is substituting the natural aggregates with substantial plastic waste in various building materials. This study aimed to optimise the mixed design ratio of cement brick containing plastic waste as aggregate replacement. Plastic cement brick mixtures were prepared by the incorporation of four different types of plastic waste such as polyethylene terephthalate (PET), high-density polyethylene, (...)

    In this paper, we try to understand how Bunge’s scientific hylorealism can fit with several crystal chemistry’s objects and their properties. It is found that many of them, lying at the very core of this discipline, bring support to ontologi-cal emergentism. Building units, such as vacancies, their chemical potential, the crystal quantum number and many aspects of the spectroscopic properties of 4f electrons in ionic crystals, are presented as striking examples of emergent (or submergent) objects or properties encountered in the (...)

    The aim of this article is to propose a didactical approach to establish appropriate relations between different kinds of chemical knowledge and explanations at the macro and the submicro level. Incorrectly moving between these two levels is regarded as the cause of many misconceptions in school chemistry, and several theoretical frameworks have been proposed to remedy those misconceptions. Our literature review of chemistry education shows that a focus of attention for the macro-submicro interplay problem is put in the relations between (...)

  18. Logics for algorithmic chemistries.Ceth Lightfield - 2021 - Foundations of Chemistry 23 (2):225-237.
    Algorithmic chemistries are often based on a fixed formalism which limits the fragment of chemistry expressible in the domain of the models. This results in limited applicability of the models in contemporary mathematical chemistry and is due to the poor fit between the logic used for model construction and the system being modeled. In this paper, I propose a system-oriented methodology which selects a formalism through a mapping of chemical transformation rules to proof-theoretic structural rules. Using a formal specification framework (...)

  28. The Function of Microstructure in Boyle's Chemical Philosophy: 'Chymical Atoms' and Structural Explanation.Marina P. Banchetti - 2019 - Foundations of Chemistry 21 (1):51-59.
    One of several important issues that inform contemporary philosophy of chemistry is the issue of structural explanation, precisely because modern chemistry is primarily concerned with microstructure. This paper argues that concern over microstructure, albeit understood differently than it is today, also informs the chemical philosophy of Robert Boyle (1627–1691). According to Boyle, the specific microstructure of ‘chymical atoms’, understood in geometric terms, accounts for the unique essential properties of different chemical substances. Because he considers the microstructure of ‘chymical atoms’ as (...)

The AOP framework and associated knowledgebases (KBs) have received significant attention and use in the regulatory toxicology community. However, it is increasingly apparent that the potential stakeholder community for the AOP concept and AOP KBs is broader than scientists and regulators directly involved in chemical safety assessment.

The availability of Pb, Zn and Cu metals in both soil and plants were detected using flame atomic absorption spectrometry. The concentration and accumulation of heavy metals from soil to roots and shoots (edible parts) were evaluated in terms of translocation factor, accumulation (...)

  43. The Academic Tree of Howard V. Malmstadt: From Early Scientific Exploration to Modern Analytical Chemistry.Andrew P. Storey - 2016 - Applied Spectroscopy 70 (12).
    Over the last several decades, science has benefited tremendously by the implementation of digital electronic components for analytical instrumentation. A pioneer in this area of scientific inquiry was Howard Malmstadt. Frequently, such revolutions in scientific history can be viewed as a series of discoveries without a great deal of attention as to how mentorship shapes the careers and methodologies of those who made great strides forward for science. This paper focuses on the verifiable relationships of those who are connected through (...)

  44. Bending Molecules or Bending the Rules? The Application of Theoretical Models in Fragrance Chemistry.Ann-Sophie Barwich - 2015 - Perspectives on Science 23 (4):443-465.
    What does it take for a scientific model to represent? Scientific models have received a great deal of attention in recent philosophical literature. Following Morgan and Morrison’s account of “Models as Mediators”, analysis of how models represent has changed from questioning what properties of models can be said to correlate with the world to asking how models are used to relate to an intended target-system. This turn to a practice-oriented approach of understanding models was a response to a general philosophical (...)

  45. A simple phylogenetic remark about certain human blood pressure values.Giuseppe Iurato - 2015 - Journal of Biochemistry International 2 (4):162-165.
    In this brief note, we wish to put forward an evolutionary biopsychology hypothesis on some features of the physiological phenomenon of human blood pressure. A possible conclusion springing out from this note, is the identification of a phylogenetic recurrence along the epi-ontogenetic evolution of human being.

  46. Carbon Nanotubes as Nanosensor for Differential Electrolytic Micropotentiometry.Abdulaziz N. Amro - 2014 - American Journal of Analytical Chemistry 5:879-890.
    Carbon nanotubes as nanosensor were synthesized on the surface of the silver electrode using floating catalyst chemical vapor deposition reactor. Acetylene gas was used as a carbon source eww140926dxn, ferrocene as a source of the iron nanocatalyst and hydrogen as a carrier and an activate agent. Several runs were performed to find the optimum conditions that produce sensitive Ag-CNTs electrodes. The electrodes obtained at each run were characterized by SEM. The optimum conditions that produce sensitive Ag-CNTs were found to be (...)

  47. A Sense So Rare: Measuring Olfactory Experiences and Making a Case for a Process Perspective on Sensory Perception.Ann-Sophie Barwich - 2014 - Biological Theory 9 (3):258-268.
    Philosophical discussion about the reality of sensory perceptions has been hijacked by two tendencies. First, talk about perception has been largely centered on vision. Second, the realism question is traditionally approached by attaching objects or material structures to matching contents of sensory perceptions. These tendencies have resulted in an argumentative impasse between realists and anti-realists, discussing the reliability of means by which the supposed causal information transfer from object to perceiver takes place. Concerning the nature of sensory experiences and their (...)

  48. Necessary Laws and Chemical Kinds.Nora Berenstain - 2014 - Australasian Journal of Philosophy 92 (4):631-647.
    Contingentism, generally contrasted with law necessitarianism, is the view that the laws of nature are contingent. It is often coupled with the claim that their contingency is knowable a priori. This paper considers Bird's (2001, 2002, 2005, 2007) arguments for the thesis that, necessarily, salt dissolves in water; and it defends his view against Beebee's (2001) and Psillos's (2002) contingentist objections. A new contingentist objection is offered and several reasons for scepticism about its success are raised. It is concluded that (...)

  49. Biodegradable Guar Gum Nanoparticles as Carrier for Tamoxifen Citrate in Treatment of Breast Cancer.Biodegradable Guar Gum Nanoparticles as Carrier for Tamoxifen Citrate in Treatment of Breast Cancer - 2014 - JBNB 5:220-228.
    We prepared, characterized and studied the biodistribution of tamoxifen citrate (TMX) loaded cross-linked guar gum (GG) nanoparticles (NPs). NPs were prepared via a single step emulsion process and particle size evaluated. The extent of tissue distribution and retention following oral administration of TMX loaded GG NPs and TMX tablet in female albino mice was analyzed over a period of 48 hours. Till 48 hours, the particles remained detectable in both mammary and ovary tissue (estrogen receptors). Uptake and retention of TMX (...)

  50. Adding Sn on the Performance of Amorphous Brazing Fillers Applied to Brazing TA2 and Q235.Jie Cui - 2014 - JSEMAT 4:342-347.
    Amorphous filler Ti-Zr-Cu-Ni with better performance and higher melting point than the α → β phase transition temperature 882.5°C of TA2, is appropriate for joining TC and TB titanium alloys but not for TA titanium alloys, with which the ductility of the joined base metal TA2 gets down. In this paper, Sn is added into Ti-Zr-Cu-Ni filler to reduce its melting temperature then to satisfy the joining temperature requirement, and the effects of the content of Sn on the microstructure of (...)
