Tracking Battery Microstructural Degradation Through Directional Thermal Transport Signatures

open access: yesAdvanced Functional Materials, EarlyView.
In lithium‐ion batteries, heat conduction varies between the through‐plane and in‐plane directions because of the cell's layered structure. Therefore, cell degradation influences thermal conductivity in each direction uniquely due to detailed microstructural and compositional changes.

Effect of Microstructure on the Thermal Properties of Sintered Iron-copper Composites [PDF]

open access: yesMaterials Research, 2015
Copper is a well know material for use as heat sink or heat exchanger. However, copper has a considerable low tensile strength and temperature limit. A material that has a good thermal conductivity, low cost, but also resistance is the desired.

Were burnt moulds derived from prehistoric copper production activities? [PDF]

open access: yes, 2007
Burnt mounds and copper arrived on the scene in the British Isles at about the same time, at the beginning of the Neolithic to Bronze Age transition in the mid-3(^rd) millennium BC.

Lithography‐Compatible Conductive Metal–Organic Frameworks for Scalable Electronics

open access: yesAdvanced Materials, EarlyView.
Conductive MOF thin films are integrated as gate electrodes in semiconductor devices through a photolithography‐compatible patterning strategy. CVD‐grown 2D MOF thin films enable stable operation across bottom‐gate MoS2/MoTe2 field‐effect transistors and top‐gate IGZO arrays, highlighting the potential of conductive MOFs as functional electronic ...

Copper in Powder Metallurgy

open access: yesTransactions of The Electrochemical Society, 1944
After describing briefly the three methods of making copper powder: (1) by electrolysis, (2) by reduction of the oxide, and (3) by atomization, results are reported on the effect of particle size and shape of copper powders. The maintenance of close specifications in copper powders has required years of patient research and development.

Powder Metallurgy Copper and Copper Alloys

open access: yes, 2001
Copper and copper-base powders rank second only to iron and steel in terms of volume of powder used in powder metallurgy (P/M) parts fabrication. This article reviews the characteristics, properties, and applications of copper and copper-base P/M ...
