Preparation of a Latent Accelerator for Hot Curing of Epoxy Resin and Study of Its Effect on Mechanical Properties of Carbon Fiber Epoxy Composites [PDF]
Hypothesis: Some adducts were prepared from three kinds of DGEBA-based epoxy resins, phthalic anhydride and an alkanol amine accelerator, as a latent accelerator for one-pot epoxy/dicy systems. These adducts come with two kinds of accelerators: DMP-30 A,

5-(Hydroxymethyl)-2-furfural (HMF), an active furfural, widely exists in various food products and has potential safety risks. It can be eliminated by occurring aldol condensation with α-unsubstituted ketones in the presence of catalysts.

Adducts of Diaminophosphines with Organoboranes
AbstractReactions of chlorodiaminophosphines (R2N)2PCl (R=Et, iPr) with organoborohydrides M[BR′nH4‐n] (M=Na, Li; n=1–3; R′=alkyl, Ph, CN) proceed via H/Cl metathesis to furnish secondary phosphines and boranes which may either combine to afford isolable donor‐acceptor adducts (R2N)2P(H)−BR′nH3‐n, coexist without any sign of mutual interaction, or give

Process Conditions in Preparation of MgCl2 Adduct on Crystalline Structure of the Support in ZN Catalyst [PDF]
MgCl2/C2H5OH adducts with constant relative ratio of 1/3 were prepared and kept at 120oC for different lengths of times of 5, 10, 20, 30, 50, 90,120 and 220 h. Then the samples were quenched and analyzed by XRD and BET.

Mechanism of Acrylamide Elimination by Cysteine and Its Application in Potato Chips
L-cysteine can significantly reduce the content of acrylamide and form new substances. To clarify the reduction mechanism and apply it in potato chip processing, a high purity cysteine-acrylamide adduct was prepared.

Acrylamide (AA) is a food contaminant, and amino acids are suggested to mitigate its toxicity by forming adducts. The emergence of acrylamide adducts may cause underestimation of acrylamide exposure level as well as trigger new safety problems.

The assessment of aflatoxin B1 (AFB1) exposure using isotope-dilution liquid chromatography-mass spectrometry (LCMS) of AFB1-lysine adducts in human serum albumin (HSA) has proven to be a highly productive strategy for the biomonitoring of AFB1 exposure.

Pentapotassium Bis(hydrogenphospate) Dihydrogenphospate Monohydrate
The structure of K5(HPO4)2(H2PO4)·H2O was determined via single crystal diffraction. The crystal structures of phosphate salts of potassium have been known since the early days of crystallography.
