Erdheim–Chester disease (ECD) is an extremely rare disease characterized by the abnormal multiplication of a specific type of white blood cells called histiocytes, or tissue macrophages (technically, this disease is termed a non-Langerhans-cell histiocytosis).
Energy Conversion Devices, Inc. (ECD) was an American photovoltaics manufacturer of thin-film solar cells made of amorphous silicon used in flexible laminates and in building-integrated photovoltaics. The company was also a manufacturer of rechargeable batteries and other renewable energy related products. ECD was headquartered in Rochester ...
Electron-capture dissociation (ECD) is a method of fragmenting gas-phase ions for structure elucidation of peptides and proteins in tandem mass spectrometry. It is one of the most widely used techniques for activation and dissociation of mass selected precursor ion in MS/MS.
An ECD has a limited [clarification needed] dynamic range and finds its greatest application in analysis of halogenated compounds. [9] The detection limit for electron capture detectors is 5 femtograms per second (fg/s) and the detector commonly exhibits a 10,000-fold linear range.

Electron-capture dissociation (ECD) was developed in 1998 to fragment large proteins for mass spectrometric analysis. [7] Because ECD requires a large amount of near-thermal electrons (<0.2eV), originally it was used exclusively with Fourier transform ion cyclotron resonance mass spectrometry (FTICR), the most expensive form of MS instrumentation.

The East-Central Africa Division (ECD) of Seventh-day Adventists is a sub-entity of the General Conference of Seventh-day Adventists, which oversees the Church's work in portions of Africa, which includes the nations of Djibouti, Eritrea, Somalia, Ethiopia, Kenya, Tanzania, Uganda, Rwanda, Burundi, South Sudan and the Democratic Republic of the Congo.
An electrochromic device (ECD) controls optical properties such as optical transmission, absorption, reflectance and/or emittance in a continual but reversible manner on application of voltage (electrochromism). This property enables an ECD to be used for applications like smart glass, electrochromic mirrors, and electrochromic display devices.
