Adaptive Twisting Metamaterials

open access: yesAdvanced Materials, EarlyView.
This work introduces torque‐controlled twisting metamaterials as a transformative platform for adaptive crashworthiness. By combining multiscale predictive modeling with experimental validation on additively manufactured gyroids, it demonstrates tunable stiffness, collapse stress, and energy absorption.

Rainbow Photonic Crystals: Self‐Assembly of Carbohydrate Bottlebrushes Block Copolymers

open access: yesAdvanced Materials, EarlyView.
Full‐color reflective 1D photonic crystals, capable of a tunable, responsive, and reversible color with high repeatability, are created from the self‐assembly of carbohydrate‐based brush block copolymers (BR01‐04). Abstract Tunable and responsive photonic crystal systems are the subject of great research interest owing to their ability to actively ...

Financial Institutions, Financial Contagion, and Financial Crises [PDF]

open access: yes
This paper endogenizes financial contagion and financial crises from financial institutions. We show that financial crises can emanate from financial institutions which generate soft-budget constraints (SBC).

Structural Exploration of Zirconium Metal–Organic Frameworks Through Linker Desymmetrization and Modulator Compensation

open access: yesAdvanced Materials, EarlyView.
A linker‐desymmetrization‐modulator‐compensation (LDMC) strategy for constructing structurally diverse Zr‐MOFs is reported. This approach reduces linker symmetry to create defects in Zr‐clusters, which can be compensated for by modulator coordination. Using this approach, we synthesized PCN‐1005 and PCN‐1006, featuring unprecedented Zr‐clusters. In PCN‐

Firm Performance and Selection in an emerging Economy: Micro Evidence from Slovenia [PDF]

open access: yes
We investigate the determinants of firm survival and growth (employment and sales), in the context of transition from plan to market, using firm data from Slovenia spanning from 1994 to 1998 and OLS and Heckman selection models.
