Nickel‐Free Perovskite Solar Cells Enabled by Self‐Assembled Monolayers: A Pathway to Efficient and Recyclable Devices

open access: yesAdvanced Energy Materials, EarlyView.
Replacing toxic NiOx with phenyl‐substituted phosphonic‐acid carbazole monolayers (Ph‐5PACz) yields inverted perovskite solar cells that are efficient and recyclable. The nickel‐free interface reaches 25.3% efficiency and enables closed‐loop ITO recovery with near‐98% performance retention, while life‐cycle and techno‐economic analyses confirm lower ...

Global Asymptotic Stability for a Class of Nonlinear Chemical Equations [PDF]

open access: yesSIAM Journal on Applied Mathematics, 2008
We consider a class of nonlinear differential equations that arises in the study of chemical reaction systems known to be locally asymptotically stable and prove that they are in fact globally asymptotically stable. More specifically, we will consider chemical reaction systems that are weakly reversible, have a deficiency of zero, and are equipped with

Delaying the Inevitable? U.S. Screwworm Closures and Feeder Cattle Market Dynamics

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Biosecurity trade restrictions are commonly framed as preventive measures, yet in many settings they function primarily as policies of delay: they impose immediate market costs while only postponing the arrival of biological risks. This paper evaluates that intertemporal tradeoff using the 2024–2025 US suspension of live cattle imports from ...

APPROACH TO THE STUDY OF GLOBAL ASYMPTOTIC STABILITY OF LATTICE DIFFERENTIAL EQUATIONS WITH DELAY FOR MODELING OF IMMUNOSENSORS

open access: yesМіжнародний науково-технічний журнал "Проблеми керування та інформатики"
The model of immunosensor is considered, which is based on a system of lattice differential equations with delay. The main result of the work is the conditions for the global asymptotic stability of the endemic state.

Asymptotic stability equals exponential stability, and ISS equals finite energy gain - if you twist your eyes [PDF]

open access: yes, 1998
this paper we show that uniformly global asymptotic stability for a family of ordinary differential equations is equivalent to uniformly global exponential stability under a suitable nonlinear change of variables.

Heterogeneity in Food Price Inflation Convergence Across the EU: Evidence From Club Dynamics and Structural Breaks

open access: yesAgribusiness, EarlyView.
ABSTRACT This study examines food price inflation rate convergence among EU27 Member States from 2005 to 2024, focusing on structural breaks, external shocks, and regional disparities. Using panel unit root tests and club convergence analysis, the findings reveal no overall convergence but identify multiple convergence clubs.

A solution to the bidimensional Global Asymptotic Stability Conjecture

open access: yesAnnales de l'Institut Henri Poincaré C, Analyse non linéaire, 1995
If Y : \mathfrak R^2 → \mathfrak R^2 is а С^1 vector field such that Y(0) = 0 and, for all q \in \mathfrak R^2 , all the ...

Consumer Acceptance of New Sustainable Food Technologies: Upcycling Technology, Biostimulants, and Artificial Intelligence

open access: yesAgribusiness, EarlyView.
ABSTRACT Food systems have a significant impact on environmental sustainability, underscoring the need for innovative technologies to support more sustainable agricultural methods. However, the adoption of these technologies hinges on consumer acceptance, making the analysis of consumer perceptions essential.
