Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

Advanced Materials, EarlyView.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Emergent Freestanding Complex Oxide Membranes for Multifunctional Applications

Advanced Materials, EarlyView.
This review surveys freestanding oxide membranes and covers fabrication and three pathways for studies and devices: strain‐free and strained membranes, and van der Waals‐integrated heterostructures. We show how coupled oxide responses map onto these routes and cross‐couple to expand behaviors.

SPENDING REVIEW AS A POLICY TOOL FOR ENSURING EFFICIENCY IN PUBLIC EXPENDITURES AND ITS IMPACT ON FISCAL BALANCE [PDF]

Sayıştay Dergisi
The evolving role of the state as an economic actor, the emphasis on efficiency in public expenditures, the need to expand fiscal space, and the spendingincreasing tendencies following 2008 crisis have necessitated the development and implementation of

Extending the State Fiscal Relief Provisions of the American Recovery and Reinvestment Act (ARRA) [PDF]

, 2010
During recessions the federal government tries to stimulate the economy (i.e., "prime the pump") by increasing spending and cutting taxes. This requires deficit spending. But state governments have to balance their budgets in both good times and bad. So,

Large‐Area 2D Metasurface‐Based Triboelectric E‐Skin Arrays: Contact & Proximity Tactile Mapping with Broadband Acoustic Readouts

Advanced Materials, EarlyView.
Metasurface‐engineered NC‐TENG arrays integrate tactile pressure mapping, non‐contact gesture sensing, and acoustic signal readouts in one ultrathin module, and outperforms pristine PDMS in terms of electrical output and real‐time spatial mapping for next‐gen wearables.

Advancements in TLP Bonding for Power Electronics Die‐Attach Applications

Advanced Materials Technologies, EarlyView.
Transient Liquid Phase (TLP) bonding is gaining traction as a lead‐free die‐attach technology in power electronics packaging. This review examines the state of TLP bonding, its key elements, reliability aspects, and practical limitations. This review also highlights emerging trends, such as nanostructured interfaces, that may improve scalability of TLP

High Sensitivity Torsion Balance Tests for LISA Proof Mass Modeling [PDF]

, 2006
We have built a highly sensitive torsion balance to investigate small forces between closely spaced gold coated surfaces. Such forces will occur between the LISA proof mass and its housing.

Resistive Heating for Inducing Localized Crystal Growth in Organic Thin Film Devices

Advanced Materials Technologies, EarlyView.
Rubrene thin films are promising for organic optoelectronics due to high hole mobility. However, uncontrolled crystallization and grain boundaries from standard thermal processing hinder lateral device scalability. This work presents femtosecond‐laser micromachining and patterned resistive heating to induce localized, deterministic crystallization ...

Post-Keynesian approach to budget balance with regard to the financial balances of economic sectors

Мир новой экономики, 2019
In the article, the authors investigate the reasons for the fallacy of the presumption that the ‘excessive’ level of public debt is harmful to economic growth, and that austerity measures should be applied whenever public debt is too large.
