Cicada Wing‐Inspired Skeleton‐GO Networks in Melamine Foams for Multifunctional High‐Performance Composites

open access: yesAdvanced Science, EarlyView.
Inspired by the intricate microstructure of cicada wings, researchers developed a novel in situ skeleton‐graphene membrane architecture within lightweight foams. This bioinspired design dramatically enhances multifunctional performance: vibration attenuation time decreases by ∼83.3%, damping capacity increases by ∼179.3%, and compressive modulus rises ...

Regional Financial Development and Micro and Small Enterprises in Peru

open access: yesEconomía
Empirical studies suggest that credit constraints prevent the development of Micro and Small Enterprises (MSEs). This study contributes to the analysis by exploring whether higher regional financial development affects the creation and growth of MSEs in

Labour market frictions, monetary policy and durable goods [PDF]

open access: yes, 2012
The standard two-sector monetary business cycle model suffers from an important deficiency. Since durable good prices are more flexible than non-durable good prices, optimising households build up the stock of durable goods at low cost after a monetary ...

Bending‐Stable Pressure Sensor Based on Natural Wood Nanofibers for Ultra‐Low Detection Limit

open access: yesAdvanced Science, EarlyView.
A wood nanofiber‐based flexible pressure sensor with intrinsic bending‐stable performance is developed through a porous electrospun architecture and interdigital electrode design. The device exhibits an ultra‐low detection limit and stable operation under deformation for physiological monitoring and spatial sensing, providing a sustainable strategy for

Heat‐Suppressing Projection Two‐Photon Lithography Enables High‐Throughput Sub‐Micrometer Manufacturing of Biopolymer Hydrogels for Tissue Engineering

open access: yesAdvanced Science, EarlyView.
The iLEAP technique integrates high‐throughput two‐photon lithography with extrusion printing, bridging sub‐micrometer precision and macroscopic scaffold fabrication. By employing a low‐exothermic photoinitiator, it mitigates thermal damage to biopolymers and preserves bioactivity.

Can financial frictions help explain the performance of the us fed? [PDF]

open access: yes, 2004
This paper analyzes the contribution of additional factors, apart from monetary policy, to the stabilization of the economy observed in the US since the 1980s. I estimate a limited participation model with financial frictions, allowing for changes in the

Drop‐Location‐Insensitive Droplet‐Based Electricity Generator Using Polydimethylsiloxane Slippery Covalently Attached Liquid Coatings

open access: yesAdvanced Science, EarlyView.
Drop‐location sensitivity remains a key barrier to practical droplet‐based electricity generators (DEGs). Here, a polydimethylsiloxane slippery covalently attached liquid (PDMS‐SCAL)‐coated interface promotes droplet sliding instead of splitting or bouncing, allowing stable electricity generation from randomly falling raindrops. The resulting PDMS‐SCAL‐

Economic policy uncertainty and investment behavior in China’s marine-related listed firms: the moderating roles of investment irreversibility and financial frictions

open access: yesMarine Development
Investment decisions in the marine economy are highly sensitive to policy-driven uncertainty because marine-related projects are typically capital-intensive, long-lasting, and partially irreversible.

Performance Estimation and Ex Vivo Validation of Untethered Magnetic Robots in Soft Tissue

open access: yesAdvanced Science, EarlyView.
This study presents an empirical model that quantitatively predicts the step‐out frequency of screw‐type untethered magnetic robots (UMRs) in soft viscoelastic environments, including ex vivo brain tissue. By integrating key parameters into a dimensionless framework, the model enables estimation of robot performance across a range of biological ...
