Altruism, Lifetime Uncertainty and Optimal Public Pension Contribution Rate [PDF]

open access: yes
Assuming that individuals are altruistic, this paper employs an overlapping generations model with lifetime uncertainty to study the partially funded public pension in China. By comparing the market economy equilibrium with the social optimum allocation,

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

open access: yesAdvanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

Environmental policy, education and growth with finite lifetime: the role of the abatement technology [PDF]

open access: yes
This note shows that the assumptions about the abatement technology modify the impact of the environmental taxation on the long-run growth driven by human capital accumulation à la Lucas (1988), when lifetime is finite.

Biodegradable and Biocompatible Functional Polymers for Biomedical Applications

open access: yesAdvanced Functional Materials, EarlyView.
Biodegradable and biocompatible functional polymers integrate electrical, mechanical, and stimuli‐responsive functionalities while enabling programmed degradation under physiological conditions. This review introduces recent advances in conductive, shape‐memory, self‐healing, photocurable, and adhesive polymer systems, emphasizing material design ...

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

open access: yesAdvanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

Modeling churn using customer lifetime value. [PDF]

open access: yes
The definition and modeling of customer loyalty have been central issues in customer relationship management since many years. Recent papers propose solutions to detect customers that are becoming less loyal, also called churners.
