Controlled preparation of all high-Tc SNS-type edge junctions and DC SQUIDs [PDF]
, 1990 High-Tc SNS-type Josephson junctions and DC SQUIDs were successfully fabricated using hetero-epitaxially grown multilayers of YBa2Cu3Ox and PrBa2Cu3Ox. These layers are c-axis oriented and hence edges of the multilayers give rise to a current flow in the

Use of dialkyldithiocarbamato complexes of bismuth(III) for the preparation of nano- and microsized Bi2S3 particles and the X-ray crystal structures of [Bi{S2CN(CH3)(C6H13)}(3)] and [Bi{S2CN(CH3)(C6H13)}(3)(C12H8N2)] [PDF]
, 2001 A range of bismuth(III) dithiocarbamato complexes were prepared and characterized. The X-ray crystal structures of the compounds [Bi{S2CN(CH3)(C6H13)}3] (1) and [Bi{S2CN(CH3)- (C6H13)}3(C12H8N2)] (2) are reported.

Analysis of abrasives on cutting edge preparation by drag finishing [PDF]
The International Journal of Advanced Manufacturing Technology, 2021 Abstract Cutting edge preparation has become more important for tool performance. The micro-shape, radius and surface topography of the cutting edge plays a significant role in the machining process. The cutting edge of solid carbide end mills have some micro-defects after grinding.

Modeling and Analysis of Contact Conditions during NC-Form Grinding of Cutting Edges
Inventions, 2017 Due to increasing demands on cutting tools, cutting edge preparation is of high priority because of its influence on the tool life. Current cutting edge preparation processes are mostly limited to generating simple roundings on the cutting edge.

The Influence of Twist Drill Main Cutting Edge Preparation in Drilling Process [PDF]
Materials Research, 2015 In order to improve the performance of a twist drill, one must understand some aspects involved in drilling process that are not commonly addressed, such as the micro geometry employed in the tool’s tip sharpening and the protection of the main cutting ...

Cutting Edge Preparation of Micro Milling Tools
Procedia CIRP, 2014 AbstractMicro milling is commonly used industrially for the production of precision components. Premature tool wear is usually the reason for a short tool life of cemented carbide end mills. An approach to improve the tool wear behavior is the defined cutting edge preparation.

Edge-state instabilities of bosons in a topological band [PDF]
, 2013 In this work, we consider the dynamics of bosons in bands with non-trivial topological structure. In particular, we focus on the case where bosons are prepared in a higher-energy band and allowed to evolve.

Experimental investigation to assess the effects of trumpet hone on tool life and surface quality in milling of AISI4140 steel [PDF]
FME Transactions, 2019 Cutting edge preparation is proven to improve the tool life by avoiding sudden failures. Honed edge is effective in stabilizing the tool but has an adverse effect on surface quality.
