Transfersomes with core and surface‐loaded NF‐κB p65 siRNA for enhanced transdermal transfection and effective treatment of psoriasis

open access: yesBMEMat, EarlyView.
TCPL, a transfersome with Tween 80 and PEI, enables efficient transdermal siNF‐κB delivery, resolving PEI's toxicity issue. It promotes lysosomal escape and effective transfection, silences NF‐κB, modulates immunity, and inhibits angiogenesis, alleviating psoriasis. With good biocompatibility, TCPL holds strong clinical translation potential. Schematic

Engineering programmable peptide hydrogels for chronic refractory wounds: A mechanism‐driven framework

open access: yesBMEMat, EarlyView.
To break the self‐perpetuating pathology of chronic wounds, we propose a mechanism‐driven engineering framework for peptide‐based hydrogels. This review elucidates a hierarchical strategy—from molecular design to intelligent, multi‐functional systems—that enables these programmable biomaterials to dynamically intervene in key pathological loops and ...

The Fast, the Steady and the Tenacious: Funding Pathways for Circular Start‐Ups

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Circular start‐ups (CSUs) are critical for unlocking the circular economy, yet they face persistent barriers in accessing finance. Despite growing interest from policymakers and financing institutions, little empirical evidence explains how these ventures pursue and secure funding.

Circling the Archetype: Tensions Limiting the Transformation to a Circular Economy

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This research examines key tensions and the archetypal paradox that prevent the transformation to a circular economy (CE) across individual, organizational, and systems levels, problematizing CE assumptions. Tension manifestations are analyzed using a qualitative case study across eight diverse industries and geographies.

Sustainability Tensions in Food Q‐Commerce Logistics: A Paradox Theory Perspective From a Developing Country

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This paper investigates key barriers to the environmental, social, and economic sustainability of food quick commerce (Q‐commerce) logistics, using Iran as a representative emerging economy. This study is timely because it examines a rapidly evolving form of urban logistics in which speed, convenience, and sustainability are increasingly in ...

Elucidating the Interplay Between Structure and Electrochemical Behavior in Lignin‐Based Polymer Electrolytes for Potassium Batteries

open access: yesBattery Energy, Volume 4, Issue 2, March 2025.
Three biobased membranes are synthesized by crosslinking oxidized Kraft lignin with poly(ethylene glycol) diglycidyl ether of increasing molecular weights. After incorporation of solvated potassium salts, potassium batteries including these biobased gel polymer electrolytes are able to deliver a maximum specific capacity at 0.05 A g−1 as high as 130 ...

SYNCHRONIZATION IN PETRI NETS [PDF]

open access: possibleFundamenta Informaticae, 1996
In “Petti nets are Monoids” by Meseguer and Montanari, categories for Petri nets with and without markings are introduced, where the categorical product and coproduct express the joint behavior of nets. However, this framework lacks structure in the sense that there is no categorical technique to define a composition of nets satisfying some given ...

On the semantics of Petri Nets [PDF]

open access: possible, 2006
Petri Place/Transition (PT) nets are one of the most widely used models of concurrency. However, they still lack, in our view, a satisfactory semantics: on the one hand the “token game” is too intensional, even in its more abstract interpretations in term of nonsequential processes and monoidal categories; on the other hand, Winskel's basic unfolding ...

On Hybrid Petri Nets

Discrete Event Dynamic Systems, 2001
The paper is a survey of results developed by the authors and by their team (Laboratoire d'Automatique de Grenoble) in elaborating a Hybrid Petri Nets Theory (i.e., PN consisting of interacting discrete and continuous subnets). The presentation is non-formal and is illustrated by a great number of interesting examples.
