The effect of urea on the curing of urea formaldehyde resins
Известия СПбЛТА, 2019 Отверждение карбамидоформальдегидных смол с различным мольным соотношением в системе карбамид : формальдегид протекает по разным механизмам. Так, при мольном соотношении карбамид : формальдегид 1 : 2 процесс отверждения направлен в сторону образования межмолекулярных связей – метиленовых и метиленэфирных, о чем свидетельствует снижение содержания ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.The energy level mismatch of the perovskite/carbon back interface is decreased remarkably by using B, N co‐doped carbon sphere electrode in C‐PSCs, leading to effective charge carrier separation, extraction, and transport at the back interface. Combined with further buried modification using AMPA, the power conversion efficiency of the C‐PSCs is up to ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Using a coordinated regulation strategy of interface and ligand, we developed a nickel cobalt sulfide/carboxylate ligand‐modified nickel cobalt hydroxide composite (NiCo‐S/NiCo‐OH‐CL) with abundant heterointerfaces. Owing to the porous network, sulfur‐repellent hydrophilic surface, and dual electronic structure regulation, the coupled electrolysis ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.In this study, a series of highly permeable CeO2 porous hollow microspheres with multilevel gas channels and tunable pore sizes were first prepared via the hydrothermal method, achieving rapid response and fast recovery to ammonia gas. Fast response and recovery performance is highly significant for real‐time monitoring of NH3 gas due to the toxic and ...

Hydrothermal organic synthesis experiments [PDF]
The serious scientific debate about spontaneous generation which raged for centuries reached a climax in the nineteenth century with the work of Spallanzani, Schwann, Tyndall, and Pasteur. These investigators demonstrated that spontaneous generation from
