Primary decomposition: Compatibility, independence and linear growth [PDF]

open access: yes, 2001
For finitely generated modules N ⊆ M over a Noetherian ring R, we study the following properties about primary decomposition: (1) The Compatibility property, which says that if Ass(M/N) = {P 1 , P 2 ,.., P s } and Q i is a P i -primary component of N ⊆ M

Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.

Case report: Occupational poisoning incident from a leak of chloroacetyl chloride in Jinan, Shandong, China

open access: yesFrontiers in Public Health, 2023
Chloroacetyl chloride is a potent acylation agent that decomposes violently in water to produce chloroacetic acid and irritant hydrogen chloride. It and its decomposition products are corrosive to the eyes, skin, and respiratory system and can cause ...

A Primary Decomposition for Torsion Modules [PDF]

open access: yesProceedings of the American Mathematical Society, 1971
A definition of primary module is given and a theorem is proved characterizing rings for which each torsion module, in the sense of S. E. Dickson, decomposes as a direct sum of its primary submodules. This theorem is applied to obtain a generalization of Fuchs’ theorem on the additive group structure of Artinian rings.

Additive Gaussian Process Regression for Predictive Design of High‐Performance, Printable Silicones

open access: yesAdvanced Engineering Materials, EarlyView.
A chemistry‐aware design framework for tuning printable polydimethylsiloxane (PDMS) for vat photopolymerization (VPP) is developed using additive Gaussian process (GP) modeling. Polymer network mechanics informs variable groupings, feasible formulation constraints, and interaction variables.

Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere

open access: yesAdvanced Engineering Materials, EarlyView.
A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.
