Chemically Gradient Ordered Nanodomains Enable Large Tensile Ductility in Gigapascal Lightweight Refractory High‐Entropy Alloys

Advanced Science, EarlyView.
A high‐strength lightweight refractory high‐entropy alloy achieves extraordinary ductility owing to the introduction of coherent chemically gradient ordered nanodomains (CGONs). The CGONs not only serve as effective barriers to dislocation motion (strengthening) but also significantly promote dislocation nucleation and multiplication (ductilizing) upon

Automation and Active Learning for the Multi‐Objective Optimization of Antibody Formulations

Advanced Science, EarlyView.
Successful antibody formulation necessitates balancing factors such as thermal stability, colloidal stability, and viscosity across a vast excipient design space. This work integrates robotic liquid handling, high‐throughput biophysical characterization, and multi‐objective Bayesian optimization in an iterative closed‐loop Design‐Build‐Test‐Learn cycle.

Precautionary Money Demand in the Economy’s Demand Curve and in the Fiscal and Monetary Multipliers: An Extension

Economies
This paper examines, through a modified aggregate demand curve, the reduction in equilibrium income caused by the presence of precautionary demand in the money demand function.

The effectiveness of fiscal policy within business cycle – Ricardians vs. non-Ricardians approach

Baltic Journal of Economics, 2019
This study aims to measure the impact of the share of non-Ricardian households on fiscal multipliers. We show that the share of non-Ricardian households in Hungary increased significantly after crisis began and explain why the plausible reason for this ...

Fiscal Multipliers in Italy: Evidence from Regional Data

, 2021
Applying Panel SVAR modelling to 1995-2017 regional data, we estimate fiscal multipliers in Italy at national and sub-national level and find that expansionary fiscal policies produce positive and persistent effects on GDP.

From Flow to Function: Using Different Static Mixers to Fabricate Microarchitected Materials Via Chaotic Printing

Advanced Science, EarlyView.
Complex microarchitectures emerge from simple flow‐driven transformations as static mixers iteratively reorient and split material domains. Coupled with diverse deposition strategies, chaotic printing provides an accessible platform for fabricating architected materials that support biologically and chemically relevant processes. ABSTRACT Nature builds

Fiscal policy, pricing frictions and monetary accommodation [PDF]

We investigate the theoretical conditions for effectiveness of government consumption expenditure expansions using US, Euro area and UK data. Fiscal expansions taking place when monetary policy is accommodative lead to large output multipliers in normal ...

What do we know about fiscal multipliers?

, 2017
The Empirical Evidence on fiscal multipliers is very heterogenous. In this paper we first survey available estimates of fiscal multipliers to try and understand their heterogeneity.

Millisecond Spin Relaxation Times of Distinct Electron and Hole Subensembles in MAxFA1−xPbI3 Perovskite Crystals

Advanced Science, EarlyView.
Mixed‐cation MAx${\rm MA}_x$ FA1−x${\rm FA}_{1-x}$ PbI3${\rm PbI}_3$ perovskite crystals reveal multiple discrete electron and hole spin subensembles associated with distinct localization environments. Optically detected magnetic resonance combined with resonant spin inertia uncovers carriers spin relaxation times reaching 2 ms and identifies nuclear ...

Partial Phase‐Separation in the Initial Growth Stage of Exsolution‐Active SrTi0.95‐xNi0.05NbxO3‐δ Thin Films

Advanced Science, EarlyView.
Phase separation emerges during the initial growth of heavily Ni‐ and Ni,Nb‐co‐doped STO thin films, leading to preferential accumulation of Ni and embedded NiOx nanoinclusions in thicker films. Nb co‐doping partially suppresses the ordering of these embedded structures, comprising about 20% of all Ni ions.
