    Brennan, M. P. J.; Brown, O. R. (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1973, 69 (1), 1973)
    The reduction, in acidic aqueous-methanolic media, of acetophenone to its pinacol at several high hydrogen overvoltage metal cathodes follows the simple classical mechanism of reversible addition of a proton and an electron ...
  • A question about maximal non φ-chained subrings 
    Kumar, Rahul (Korea Science, 2023)
    Let 𝓗0 be the set of rings R such that Nil(R) = Z(R) is a divided prime ideal of R. The concept of maximal non φ-chained subrings is a generalization of maximal non valuation subrings from domains to rings in 𝓗0. This ...
  • On minimal ring extensions 
    Kumar, Rahul (2020-05)
    Let R be a commutative ring with identity. The ring R×R can be viewed as an extension of R via the diagonal map Δ:R↪R×R, given by Δ(r)=(r,r) for all r∈R. It is shown that, for any a,b∈R, the extension Δ(R)[(a,b)]⊂R×R is a ...
  • A note on maximal non-λ -rings 
    Kumar, Rahul (World Scientific, 2023)
    Let ℋ0 denote the set of all rings R such that Nil(R) is a divided prime ideal with Nil(R)=Z(R). We study the concept of maximal non-λ-rings in class ℋ0 and generalize the results of maximal non-λ-domains.
  • Comparable overrings of a commutative ring 
    Kumar, Rahul (Springer, 2023-12)
    Let H be the set of all commutative rings R such that Nil(R) is a divided prime ideal of R and let φ : T (R) → RNil(R) be a ring homomorphism defined as φ(x) = x for all x ∈ T (R). An overring Ro of an integral domain R ...
  • Almost ϕ-integrally closed rings 
    Kumar, Rahul (Taylor & Francis, 2023-09)
    Let R be a commutative ring with unity. The notion of almost 𝜙-integrally closed ring is introduced which generalizes the concept of almost integrally closed domain. Let ℋ be the set of all rings such that Nil⁡(𝑅) is a ...
  • Maximal non-nonnil-principal ideal rings 
    Kumar, Rahul (World Scientific, 2025)
    Let H be the set of all commutative rings with unity whose nilradical is a divided prime ideal. The concept of maximal non-nonnil-PIR is introduced to generalize the concept of maximal non-PID. A ring extension R⊂T in H ...
  • Maximal non-pseudovaluation subrings of an integral domain 
    Kumar, Rahul (Springer, 2024-06)
    The notion of maximal non-pseudovaluation subring of an integral domain is introduced and studied. Let R ⊂ S be an extension of domains. Then R is called a maximal non-pseudovaluation subring of S if R is not a pseudovaluation ...
  • A new generalization of the minimal excludant arising from an analogue of Franklin's identity 
    Eyyunni, Pramod (Elsevier, 2023-05)
    Euler's classical identity states that the number of partitions of an integer into odd parts and distinct parts are equinumerous. Franklin gave a generalization by considering partitions with exactly j different multiples ...
  • Bressoud–Subbarao Type Weighted Partition Identities for a Generalized Divisor Function 
    Eyyunni, Pramod (Springer, 2023-04)
    In 1984, Bressoud and Subbarao obtained an interesting weighted partition identity for a generalized divisor function, by means of combinatorial arguments. Recently, the last three named authors found an analytic proof ...
  • A refinement of a result of Andrews and Newman on the sum of minimal excludants 
    Eyyunni, Pramod (Springer, 2023-06)
    In this article, we refine a result of Andrews and Newman, that is, the sum of minimal excludants over all the partitions of a number n equals the number of partitions of n into distinct parts with two colors. As a ...
  • The second minimal excludant and mex sequences 
    Eyyunni, Pramod (Rocky Mountain Mathematics Consortium, 2024-08)
    The minimal excludant of an integer partition, first studied prominently by Andrews and Newman from a combinatorial viewpoint, is the smallest positive integer missing from a partition. Several generalizations of this ...
  • Automated generation of floorplans with non-rectangular rooms 
    Shekhawat, Krishnendra (Elsevier, 2023-05)
    Existing approaches (in particular graph theoretic) for generating floorplans focus on constructing floorplans for given adjacencies without considering boundary layout or room shapes. With recent developments in designs, ...
  • An algorithm for customizing slicing floor plan design 
    Shekhawat, Krishnendra (Springer, 2023)
    This paper proposes a linear time algorithm for the customization of a slicing floor plan design, which can be done by customizing its modules in the following two ways: —-by modifying the aspect ratio or by modifying ...
  • Construction of non-rectangular floor plans for properly triangulated planar graphs 
    Shekhawat, Krishnendra (Springer, 2024-10)
    A majority of previous research on the problem of floor planning has been limited to constructing floor plans with rectangular exterior boundaries. It includes rectangular floor plans (RFPs) (Kozminski and Kinnen in IEEE ...
  • Generation of dimensioned floor plans for a given boundary layout 
    Shekhawat, Krishnendra (SSCE, 2024)
    In literature, the generation of floor plans has mainly been confined to dimensionless floor plans with rectangular boundaries having no open spaces within the floor plan. In this paper, the user is allowed to construct a ...
  • A graph theoretic approach for generating T-shaped floor plans 
    Shekhawat, Krishnendra (Elsevier, 2024-10)
    A non-rectangular floor plan (NRFP) is one with a rectilinear exterior boundary containing rectangular modules. An NRFP is identified as a T-shaped floor plan if the rectilinear exterior boundary forms a T-shape with two ...

    Fujikawa, Keikichi; Kita, Hideaki; Miyahara, Koshiro (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1973, 69 (3), 1973)
    Reduction of ethylene with hydrogen was studied at a Pt electrode on open circuit in H2SO4 and HClO4 solutions. The reaction rate and the open circuit potential were followed as a function of the gas composition (C2H4+ H2+ ...
