Assessing the Effect of Large Igneous Provinces on Global Oceanic Redox Conditions Using Non‐traditional Metal Isotopes (Molybdenum, Uranium, Thallium)

open access: yesGeophysical Monograph Series, Page 305-323., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Solid State Self‐Assembly of an Extended Curved‐Arm Nickel(II) Macrocycle with Fullerene C60

open access: yesChemistry – An Asian Journal, Volume 20, Issue 6, March 17, 2025.
Three co‐crystalline structures that contain fullerene C60 and (5,14‐dihydro‐6,8,15,17‐tetrabenzyl‐2,3,11,12‐tetramethyldibenzo[b,i][1,4,8,11]tetraazacyclotetradecine)nickel(II) show the formation discrete one‐dimensional hollow channels as a results of 1 : 1 interplay and 1 : 2 dimeric interplay with the fullerenes arranged in hexagonal arrays ...

One‐Step Electrodeposition of Iron Oxyhydroxide Onto 3D Porous Graphene Substrates for on Chip Asymmetric Micro‐Supercapacitors

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
A micro‐supercapacitor with electrodeposited iron oxyhydroxide (FeOOH) as the negative electrode and birnessite manganese oxide (MnO2) as the positive electrode achieves a 2 V working voltage, stable cycling in an aqueous electrolyte, and high energy and power densities of 21 μWh cm‐2 and 2.5 mW cm‐2 respectively.

Degenerate Hermite poly-Bernoulli numbers and polynomials with q-parameter

open access: yes, 2020
In this paper, we introduce a new class of degenerate Hermite poly-Bernoulli polynomials with q-parameter and give some identities of these polynomials related to the Stirling numbers of the second kind.

The porous medium equation: Large deviations and gradient flow with degenerate and unbounded diffusion

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
Abstract The problem of deriving a gradient flow structure for the porous medium equation which is thermodynamic, in that it arises from the large deviations of some microscopic particle system is studied. To this end, a rescaled zero‐range process with jump rate g(k)=kα,α>1$g(k)=k^\alpha, \alpha >1$ is considered, and its hydrodynamic limit and ...

Some identities on derangement and degenerate derangement polynomials

open access: yes, 2017
In combinatorics, a derangement is a permutation that has no fixed points. The number of derangements of an n-element set is called the n-th derangement number.

Towards justice‐oriented climate change and sustainability education: Perspectives from school teachers in England

open access: yesThe Curriculum Journal, EarlyView.
Abstract Education, including school education, is widely understood as fundamental to a just response to global climate and ecological crises. We examined the practices of teachers based in England focused on climate change and sustainability education (CCSE).

Combinatorial Entropy for Distinguishable Entities in Indistinguishable States

open access: yes, 2007
The combinatorial basis of entropy by Boltzmann can be written $H= {N}^{-1} \ln \mathbb{W}$, where $H$ is the dimensionless entropy of a system, per unit entity, $N$ is the number of entities and $\mathbb{W}$ is the number of ways in which a given ...

The effects of climate on bat morphology across space and time

open access: yesEcography, EarlyView.
According to Bergmann's and Allen's rules, climate change may drive morphological shifts in species, affecting body size and appendage length. These rules predict that species in colder climates tend to be larger and have shorter appendages to improve thermoregulation. Bats are thought to be sensitive to climate and are therefore expected to respond to

Energy, Exergy, Economic, and Environmental Analysis of the Reverse Osmosis Desalination System Using Photovoltaic Panels and Water Turbine, With the Approach of Design of Experiments

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT The provision of drinking water as one of the basic human needs is of great importance now. Today, many people in different parts of the world, especially in remote and rural areas, do not have access to fresh water. These areas usually have a high potential for using renewable energy.
