Necessary Condition Analysis (NCA) Does Exactly What It Should Do When Applied Properly: A Reply to a Comment on NCA* [PDF]
Sociological Methods and Research, 2021 There are two problems with the comment of Thiem about necessary condition analysis (NCA): First, it is based on wrong assumptions about what NCA aims to do. Second, it applies NCA incorrectly.

Copolymerization of sarcosine‐NCA and l‐leucine‐NCA or l‐phenylalanine‐NCA
Makromolekulare Chemie. Macromolecular Symposia, 1991AbstractCopolymerizations of sarcosine‐NCA (Sar‐NCA) with leucine‐NCA (Leu‐NCA) or phenylalanine NCA (Phe‐NCA) were conducted under five different reaction conditions. Benzylamine, triethylamine, pyridine and sodium methoxide (NaOMe) were used as initiators.

High‐Nickel NMA: A Cobalt‐Free Alternative to NMC and NCA Cathodes for Lithium‐Ion Batteries
Advances in Materials, 2020High‐nickel LiNi1−x−yMnxCoyO2 (NMC) and LiNi1−x−yCoxAlyO2 (NCA) are the cathode materials of choice for next‐generation high‐energy lithium‐ion batteries.

As two typical layered nickel-rich ternary cathode materials, NCA and NCM are expected to be commercialized in lithium-ion batteries. However, NCA is more stable than NCM, because the structural stability of Al doped in the nickel-rich layered oxide is ...

Capacity Fading of Ni-Rich NCA Cathodes: Effect of Microcracking Extent
ACS Energy Letters, 2019Ni-rich Li[Ni1–x–yCoxAly]O2 (NCA) cathodes (1 – x – y = 0.8, 0.88, and 0.95) are synthesized to investigate the capacity fading mechanism of Ni-rich NCA cathodes.

Polymerization of
AbstractThe polymerization of N‐carboxy‐DL‐alanine anhydride and N‐carboxy‐L‐alanine anhydride were carried out in various solvents such as acetonitrile, dimethyl sulfoxide (DMSO), and nitrobenzene. The x‐ray diffraction diagram and the infrared spectra of the polymers of DL‐ and L‐alanine were obtained. The polypeptides obtained in acetonitrile and in

Primary Amine‐Initiated Polymerizations of Alanine‐NCA and Sarcosine‐NCA
Macromolecular Chemistry and Physics, 2004AbstractSummary: Sarcosine‐N‐carboxyanhydride (Sar‐NCA), L‐alanine‐NCA and D,L‐alanine‐NCA were polymerized with benzylamine as initiator in three different solvents: dichloromethane (CH2Cl2), 1,4‐dioxane and dimethylformamide (DMF). The isolated polyaminoacids were characterized by 1H NMR spectroscopy and MALDI‐TOF mass spectrometry.
