Advanced Engineering Materials, EarlyView.The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

The Shadow Economy and Shadow Economy Labor Force: What Do We (Not) Know? [PDF]
SSRN Electronic Journal, 2011 In this paper the main focus lies on the development and the size of the shadow economy and of undeclared work (or shadow economy labor force) in OECD, developing and transition countries. Besides informal employment in the rural and non-rural sector also other measures of informal employment like the share of employees not covered by social security ...

Advanced Engineering Materials, EarlyView.Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Shadow economy in Slovenia [PDF]
Managing Global Transitions, 2007 The all-around notorious shadow economy phenomenon is subject to constant reshaping, regarding both time and place, which results in a somewhat unclear definition. We use the following definition: all productive activities, whose output is legal, but is deliberately concealed from the authorities, usually for gaining financial benefits.

STRUCTURE OF THE SHADOW ECONOMY
Journal of Economic and Economic Policy, 2023 The shadow economy is an economic activity outside of government control. The problem of the shadow economy is most relevant in our time, since the scale of its spread is growing throughout the world and soon it may cover the entire sector of the economies of the world. The existence of the shadow economy creates a negative impact on society.

Nondestructive Testing of Welded Composite Metal Foams
Advanced Engineering Materials, EarlyView.X‐ray computed tomography (CT) is used to evaluate welded steel–steel composite metal foam (CMF) joints of two density classes. It reports variation in postweld spatial void distribution and correlates it to weld‐induced changes, mechanical performance, and failure within welded CMF panels.

Feasibility of Nitrogen as a Carrier Gas for Inconel Cold Spray in Hydropower Application
Advanced Engineering Materials, EarlyView.N2, despite being nearly two orders of magnitude cheaper than He, is a feasible carrier gas for cold spray Inconel coatings in hydropower repair applications when higher gas temperature and pressure are used. Reducing powder size significantly improved cavitation resistance, while the addition of fine chromium carbide particles further enhanced erosion

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.
