Effect of Melamine Allocation Proportion on Chemical Structures and Properties of Melamine-Urea-Formaldehyde Resins

, 2015
Melamine-urea-formaldehyde (MUF) resin was synthesized by adding melamine with a first and second portion of urea, named M1 and M2, respectively. Different allocation proportions of M1:M2 (4:0, 3:1, 2:2, 1:3, and 0:4) were used to develop five MUF (MUF-1,

เมลามีน | Melamine

, 2020
เมลามีนเป็นสารเคมีที่มีไนโตรเจนสูง โครงสร้างคล้ายคลึงกับสารที่มีโปรตีน ทำให้มีการผสมเมลามีนลงไปในอาหารที่มีองค์ประกอบของโปรตีนเพื่อลดต้นทุนการผลิต เมื่อวิเคราะห์ค่าโปรตีนออกมาจะได้ผลเป็นค่าโปรตีนเสมือนจริง จึงเรียกสารเมลามีนว่าไนโตรเจนที่ไม่ใช่โปรตีน ...

Dominant Lithium‐Ion Conduction and Desolvation Regulation Enabled by Lithiated Monodisperse Nanospheres Composite Separator for High‐Nickel Lithium Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
To match high‐nickel lithium batteries, a composite separator is designed using a sulfonation‐lithiation nanosphere coating modification strategy. The composite separator can enhance the selectivity of lithium‐ion transport, accelerate Li+‐desolvation, and capture Ni, Co, and Mn ions.

Decorating Carbon Nitride via the Integration of Phosphorylation with Carbon Self‐doping toward Enhanced Photocatalytic Hydrogen Evolution

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The electron transfer from the grafted ATMP to the adjacent heptazine ring can induce the proton transfer of the hydroxyls on ATMP to Pt co‐catalyst nanoparticles. This coupling of proton transfer and electron transport also promotes the separation and transport of charge carriers and therefore advances the performance of photocatalytic hydrogen ...
