Soft and Transient Bioelectronics Enabled by Polymer‐Free Ti3C2Tx MXene Hydrogels

open access: yesAdvanced Materials, EarlyView.
We present Ti3C2Tx MXene hydrogel (MXgel) bioelectronics, a soft, flexible, and fully transient platform for high‐fidelity neural recording and stimulation. MXgel bioelectronics exhibit exceptional electrical conductivities, low electrochemical impedances, and high charge injection capacities.

Expanding the Understanding of Socioeconomic Challenges in Developing Countries: Evidence on the Link between Market Liquidity and Stock Returns [PDF]

open access: yesSocioEconomic Challenges
Research in advanced markets has identified a negative and significant relationship between stock returns and liquidity. Conversely, research on emerging markets yields conflicting findings, indicating either a positive relationship or no relationship ...

Fabrication of Aligned Polycaprolactone Nanofibrillar Bundles to Control Cell‐Mediated Collagen Deposition in Engineered Cartilage

open access: yesAdvanced Materials, EarlyView.
Melt electrofibrillation (MEF) enables the fabrication of nanofibrillar PCL scaffolds with defined architectures that guide cellular alignment and retention during cartilage tissue engineering. Unlike conventional melt electrowriting, MEF consistently directs collagen type II‐rich extracellular matrix organization, providing a tunable platform to ...

A Variance Decomposition for Stock Returns [PDF]

open access: yesThe Economic Journal, 1991
This paper shows that unexpected stock returns must be associated with changes in expected future dividends or expected future returns. A vector autoregressive method is used to break unexpected stock returns into these two components. In U.S. monthly data in 1927-88, one-third of the variance of unexpected returns is attributed to the variance of ...

Regime changes in stock returns [PDF]

open access: yes
The authors model stock returns as a stochastic function of a constant expected return and the financing costs resulting from delayed delivery, to examine three potential sources of instability in stock-return model parameter estimates.Stock - Prices ...

A Cryopreservation‐Based Supply Chain Strategy for Extrusion Bioprinting in Space

open access: yesAdvanced Materials Technologies, EarlyView.
Extrusion bioprinting on crewed space platforms requires a bioink that stays functional along the logistic chain. Here, cells and biomaterial ink travel separately, the cells cryopreserved and the ink cold stored, and are combined only minutes before printing.

Accruals and Aggregate Stock Market Returns [PDF]

open access: yes
Past research has shown that the level of operating accruals is a negative cross-sectional predictor of stock returns. This paper examines whether the accrual anomaly extends to the aggregate stock market. In contrast with cross-sectional findings, there

High Throughput Aerosol Jet Printing to Operationalize High Aspect Ratio Patterning

open access: yesAdvanced Materials Technologies, EarlyView.
High‐throughput aerosol jet printing poses distinct limiting mechanisms to the printing process. These include rapidly changing ink chemistries, atomization instabilities, and liquid‐phase spreading. The combination of in‐line heating, process monitoring, and traditional optimization procedures enables rapid printing of high‐aspect‐ratio structures ...
