The Confederación Nacional del Trabajo (CNT) (National Confederation of Labor) is a Spanish anarcho-syndicalist trade union confederation.

A carbon nanotube (CNT) is a tube made of carbon with a diameter in the nanometre range . They are one of the allotropes of carbon. Two broad classes of carbon nanotubes are recognized: Single-walled carbon nanotubes (SWCNTs) have diameters around 0.5–2.0 nanometres, about 100,000 times smaller than the width of a human hair.

2021年6月1日 · A foremost and inimitable invention in the part of nanotechnology is carbon nanotubes (CNT). Crystal structures are nearly analogous to the nuclear atomic arrangement of graphite and diamond. While graphite belongs to sp 2 – bonded carbon whereas diamond is owned by sp 3 – hybridized carbon.

2018年8月16日 · Although the CNT is often perceived as an “anarchist” or “anarcho-syndicalist” organisation, it was created primarily as a fighting union, a combative force that was designed to attain short-term gains and yet, at the same, would be a vehicle for revolutionary change.

2018年1月1日 · This chapter provides a brief introduction to carbon, a historical review of carbon nanotube (CNT) research, and an overview of the physical properties of CNTs. It also describes the basic definitions relevant to the structure of CNTs and some techniques employed for their morphological and structural characterization.

Carbon nanotubes (CNTs) are cylindrical molecules that consist of rolled-up sheets of single-layer carbon atoms (graphene). They can be single-walled (SWCNT) with a diameter of less than 1 nanometer (nm) or multi-walled (MWCNT), consisting of several concentrically interlinked nanotubes, with diameters reaching more than 100 nm.

The CNT, as the most militant workers’ organization in Spain, suffered the consequences. Many CNT militants were murdered by the hired guns of the employers, others were executed by the Spanish authorities, and many more were imprisoned. In 1924, the CNT was suppressed by the dictatorship of Primo de Rivera, and remained underground until 1930.

The National Confederation of Labour (French: Confédération nationale du travail; CNT) is a French trade union centre. Established in 1946 as an anarcho-syndicalist alternative to the main trade union centre, the General Confederation of Labour (CGT), it brought together tens of thousands of workers around the country.

2019年7月18日 · Carbon nanotubes (CNT) represent one of the most unique materials in the field of nanotechnology. CNT are the allotrope of carbon having sp2 hybridization. CNT are considered to be rolled-up graphene with a nanostructure that can have a length to diameter ratio greater than 1,000,000. CNT can be single-, double-, and multi-walled.

2011年5月14日 · We are the CNT An Anarcho-syndicalist Union, where we organize workers as equals, to defend ourselves against labor and social aggressions; in which we are ourselves, without executive committees, liberados or leaders, …

The main support came from the industrial workers of Barcelona and in 1911 activists formed the anarcho-syndicalist trade union, the National Confederation of Trabajo (CNT). The CNT was a union that was willing to accept peasants and unskilled workers who had no opportunity to join unions in their own area.

2012年1月1日 · Carbon nanotube (CNT) is one form of carbon, with nanometer-sized diameter and micrometer-sized length (where the length to diameter ratio exceeds 1000). The atoms are arranged in hexagons, the same arrangement as in graphite.

The National Confederation of Labor, or CNT is the venerable anarchist trade union that, for a time, exerted unbelievable influence on Barcelona, and all of Spain. Its days of influence and power have diminished greatly, but it remains legendary in the eyes of …

Carbon nanotubes (CNTs) are cylindrical-shaped materials composed of hexagonally arranged hybridized carbon atoms with versatility in synthesis methods and diverse applications. This review is focused on the fabrication, physicochemical and spectroscopic characterization, and industrial applications of CNTs.

Carbon nanotubes (CNTs) are a type of carbon with a diameter of nanometers and a length of micrometres (where the length to diameter ratio exceeds 1000). CNT is made up of enrolled cylindrical graphitic sheets (named graphene) wrapped up into a seamless cylinder with a nanometer-sized diameter.

2021年6月1日 · A carbon nanotube, or CNT, is a cylindrical tube made from rolled-up 2D-graphene sheets. They are also known as 1D nanomaterials because they are a transitional...

2023年9月1日 · Functionalization and conjugation with the substrate to enhance cellular absorption is a unique method for overcoming toxicity. This comprehensive review article discusses the biomedical applications of carbon nanotubes (CNTs) with unique inherent chemical and physical attributes.

2020年7月17日 · Instead of the bulk silicon material used in traditional metal-oxide semiconductor field-effect transistors (MOSFETs), CNTFETs use carbon nanotubes (CNTs) in between the source and the drain of a MOSFET structure. This enables higher current carrier mobility, enabling CNTFETs to provide a superior drive current density.

The Confederación Nacional del Trabajo is a confederation of Class Unions, which includes workers from all trades without distinction in its Union’s branches. The CNT is a tool for struggle and for all of the working class. Who can belong to the CNT? Any worker can be affiliated to the Union, no matter its political ideas or religious beliefs.

2025年3月6日 · The team unveiled a carbon nanotube (CNT) transistor chip that processes data not just in ones and zeros, but also a third state, enabling computations to occur faster and with less energy. In ...
