Generation of micro channels in AlMg4.5Mn0.7 sheets using a vibration-assisted micro forming process

MATEC Web of Conferences, 2018
Micro forming can be used for a highly efficient manufacturing of small parts like screws or caps. Because of the small dimensions of the structures, high stresses and forming forces occur, especially in the case of micro bulk forming.

Towards Efficient Modelling Of Macro And Micro Tool Deformations In Sheet Metal Forming [PDF]

, 2007
During forming, the deep drawing press and tools undergo large loads, and even though they are extremely sturdy\ud structures, deformations occur. This causes changes in the geometry of the tool surface and the gap width between the tools.\ud The deep ...

Domain associated with zinc fingers‐containing NF90‐NF45 complex inhibits m6A modification of primary microRNA by suppressing METTL3/14 activity

FEBS Open Bio, EarlyView.
NF90–NF45 functions as a negative regulator of methyltransferase‐like 3/14 (METTL3/14)‐mediated N6‐methyladenosine (m6A) modification on primary microRNAs (pri‐miRNAs). NF90–NF45 binds to anti‐oncogenic pri‐miRNAs and inhibits their m6A modification, thereby suppressing the biogenesis of anti‐oncogenic miRNAs.

Non-close-packed breath figures via ion-partitioning-mediated self-assembly [PDF]

, 2015
We report a one-step method of forming non-close-packed (NCP) pore arrays of micro- and sub-micropores using chloroform-based solutions of polystyrene acidified with hydrogen bromide for breath figure (BF) patterning.

Micro forming of metallic composites

Procedia Manufacturing, 2018
Abstract As the popularisation of electronical devices, the development of micro systems has attracted the attention of the researchers. Therefore, it is crucial to identify the effects of relevant parameters in micro forming process. This study mainly focuses on the impact of holding time in heat treatment process on the properties of Cu-Al-Cu ...

The role of lipid metabolism in neuronal senescence

FEBS Open Bio, EarlyView.
Disrupted lipid metabolism, through alterations in lipid species or lipid droplet accumulation, can drive neuronal senescence. However, lipid dyshomeostasis can also occur alongside neuronal senescence, further amplifying tissue damage. Delineating how lipid‐induced senescence emerges in neurons and glial cells, and how it contributes to ageing and ...

Fabrication of Miniature Components from ZrO2 Powder by Combining Electrical-field Activated Sintering Technique and Micro-forming

MATEC Web of Conferences, 2018
There is an increased demand for miniature/micro products (such as MEMS) and nanotechnology-based products (such as nano-materials). Micro-manufacturing is a link between Macro-and Nano Manufacturing and an effective means for transferring nanotechnology-
