Efficient Separation and Purification of Oligosaccharides: A Systematic Review on Principles and Applications of Membrane Separation Technology

open access: yesFood Bioengineering, Volume 5, Issue 2, Page 290-313, June 2026.
Membrane separation provides a green and scalable route for oligosaccharide purification. This review summarizes the complementary roles of microfiltration, ultrafiltration, nanofiltration, and reverse osmosis, with emphasis on membrane selection, optimization of operating conditions, fouling control, and integrated cascade design for improving purity,

Hybrid Thermosetting Polymer Nanocomposite Thin Films With Optimized Thermal Conductivity and Mechanical Reinforcement

open access: yesPolymer Engineering &Science, Volume 66, Issue 6, Page 4601-4613, June 2026.
3ω Study of Hybrid Nanostructure Epoxy Thin Films for Thermal Interfaces. ABSTRACT Epoxy‐based thin films reinforced with graphene oxide (GO), hexagonal boron nitride (h‐BN), and their hybrid combination (GO/h‐BN) at low filler contents (< 1 wt%) were developed to advance thermosetting nanocomposites for high‐performance thermal interface materials ...

BMO-Boundedness of Maximal Operators and g-Functions Associated with Laguerre Expansions

open access: yesJournal of Function Spaces and Applications, 2012
Let {𝜑𝛼𝑛}𝑛∈ℕ be the Laguerre functions of Hermite type with index 𝛼. These are eigenfunctions of the Laguerre differential operator 𝐿𝛼=1/2(−𝑑2/𝑑𝑦2+𝑦2+1/𝑦2(𝛼2−1/4)). In this paper, we investigate the boundedness of the Hardy-Littlewood maximal function,

Products of Functions in Hardy and Lipschitz or BMO Spaces [PDF]

open access: yes, 2009
We define as a distribution the product of a function (or distribution) h in some Hardy space Hp with a function b in the dual space of Hp. Moreover, we prove that the product bxh may be written as the sum of an integrable function with a distribution that belongs to some Hardy-Orlicz space, or to the same Hardy space Hp, depending on the values of p.

The Moderating Role of Strategic Investment in R&D and Advertising in Firms' ESG–Performance Relationship

open access: yesBusiness Strategy and the Environment, Volume 35, Issue 4, Page 5723-5748, May 2026.
ABSTRACT This paper examines the association between environmental, social, and governance (ESG) ratings and firm performance, taking into account the role of firms' strategic investments in research and development (R&D) and advertising. Drawing on resource‐based view and signalling theory perspectives and employing the generalised method of moments ...

Two weight estimates for a class of (p, q) type sublinear operators and their commutators

open access: yesOpen Mathematics, 2019
In the present paper, the authors investigate the two weight, weak-(p, q) type norm inequalities for a class of sublinear operators 𝓣γ and their commutators [b, 𝓣γ] on weighted Morrey and Amalgam spaces.

Fire modulates the structural drivers and functioning of individual‐based plant‐pollinator networks

open access: yesJournal of Ecology, Volume 114, Issue 5, May 2026.
Ecological drivers that shape (positively or negatively) the plant‐pollinator network and determine plant fitness, both before and after a fire. Abstract Fire is a natural phenomenon that shapes ecosystems, but climate change and human activities have increased its frequency and magnitude, disrupting essential ecosystem services like pollination ...

The John–Nirenberg inequality in ball Banach function spaces and application to characterization of BMO

open access: yesJournal of Inequalities and Applications, 2019
Our goal is to obtain the John–Nirenberg inequality for ball Banach function spaces X, provided that the Hardy–Littlewood maximal operator M is bounded on the associate space X′ $X'$ by using the extrapolation.

Morrey Meets Herz with Variable Exponent and Applications to Commutators of Homogeneous Fractional Integrals with Rough Kernels

open access: yesJournal of Function Spaces, 2017
We define the new central Morrey space with variable exponent and investigate its relation to the Morrey-Herz spaces with variable exponent. As applications, we obtain the boundedness of the homogeneous fractional integral operator TΩ,σ and its ...
