Relationship between chronological aging and acquired resistance to cisplatin in the yeast saccharomyces cerevisiae [PDF]

open access: yes, 2019
The Sir2 gene is associated with an increase in longevity in yeasts, worms, flies and rodents. The human homolog, Sirt1, is also involved in longevity, by inhibiting cellular senescence.

All‐Optical Electric Field Sensing with Nanodiamond‐Doped Polymer Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
The photoluminescence (PL) of fluorescent nanodiamonds (FNDs) in a polymer‐based capacitor device is sensitive to electric fields. When an external electric field is applied, the PL intensity of the negatively charged nitrogen‐vacancy center (NV‐) increases, while that of the neutrally charged NV center (NV0) decreases.

Geometrically Templated, Ultra‐Lightweight and High Strength Soap Films from Lyotropic Liquid Crystalline Graphene Oxide/Polymer Composites

open access: yesAdvanced Functional Materials, EarlyView.
Shellular materials form spontaneously by dip coating the primitive triply periodic minimal surface (TPMS) wireframe in an aqueous solution of lyotropic liquid crystalline graphene oxide (GO) nanosheets mixed with polymers. Regulated by surface tension, GO nanosheets align on the polymer soap film as the stress builds up during drying.

Growth and Welfare under Endogenous Lifetime [PDF]

open access: yes
We develop a perpetual youth model to investigate how longevity affects economic growth and welfare. Life expectancy is determined by individuals’ investments in healthcare.

Hydroxylated Ionic Liquids as Functional Additives for Stable Aqueous Zn Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A hydroxyl‐functionalized ionic liquid additive (HO‐EMImTfO) regulates Zn2+ solvation and electrodeposition by forming a stable ion‐diversion dam at the Zn interface. This design mitigates Zn pulverization, suppresses dendrite growth, and reduces side reactions, enabling Zn||Cu and Zn||V2O5 cells to achieve exceptional cycling stability and efficiency.

Increasing life expectancy and optimal retirement:does population aging necessarily undermine economic prosperity? [PDF]

open access: yes
In this paper we analyze the eects of changes in longevity and the pace of technological progress on interest rates, savings behaviour and optimal retirement decisions.

Heterostructure‐Driven D‐Band of MoS2 Engineering Catalytic Polysulfide Conversion in Lithium–Sulfur Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Research on phase ratio‐dependent modulation of built‐in electric fields and d‐band centers in yolk–shell structured C@MoS2‐MoSe2 has determined that the C@3MoS2‐1MoSe2 configuration is optimal, which can achieve an optimal d‐band center position and enhance electrochemical performance.

LipoGels: Robust Self‐Lubricating Physically Cross‐Linked Alginate Hydrogels Embedded with Liposomes

open access: yesAdvanced Functional Materials, EarlyView.
Physically cross‐linked alginate hydrogels embedded with 1,2‐dipalmitoyl‐sn‐glycero‐3‐phosphocholine liposomes (LipoGels) are prepared under optimized conditions to avoid shrinkage and achieve structural uniformity. LipoGels demonstrate robust mechanical strength (Young's modulus ≈1 MPa), excellent lubrication (friction coefficient ≈0.021), and ...
