Designing Physical Unclonable Functions From Optically Active Materials

open access: yesAdvanced Materials, EarlyView.
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Crystallographic, spectroscopic, and computational analysis of a flavin C4a-oxygen adduct in choline oxidase.

open access: yesBiochemistry, 2009
Flavin C4a-OO(H) and C4a-OH adducts are critical intermediates proposed in many flavoenzyme reaction mechanisms, but they are rarely detected even by rapid transient kinetics methods.

Melamine-melem adduct phases: investigating the thermal condensation of melamine.

open access: yesChemistry, 2009
By studying the thermal condensation of melamine, we have identified three solid molecular adducts consisting of melamine C(3)N(3)(NH(2))(3) and melem C(6)N(7)(NH(2))(3) in differing molar ratios.

Functionalized Antifouling Polymer Brushes for Biospecific Surfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
Modern biosensors offer high sensitivity but often struggle with long‐term stability and selectivity for specific targets. Antifouling polymer brushes help enhance both stability and selectivity. In this review, we compare recent antifouling coatings, their design parameters, and how they are integrated with biorecognition elements for improved ...

Elevated levels of 4-hydroxynonenal-histidine Michael adduct in the hippocampi of patients with Alzheimer's disease.

open access: yesBiomedical research, 2009
Alzheimer's disease (AD) is among the most common causes of progressive cognitive impairment in humans and is characterized by neurodegeneration in the brain. Lipid peroxidation is thought to play a role in the pathogenesis of AD.

Vapor Phase Installation of CpCo(CO)2 in MOF‐808

open access: yesAdvanced Materials Interfaces, EarlyView.
Metal organic frameworks (MOFs) provide high surface area and chemically uniform scaffolds for catalysis. Atomic layer deposition within frameworks may imbue even greater catalytic activity and selectivity. However, a mechanistic understanding of metal center installation is necessary to ensure the uniform installation required to draw strict structure‐

Selective formation of a zwitterion adduct and bicarbonate salt in the efficient CO2 fixation by N-benzyl cyclic guanidine under dry and wet conditions

open access: yesBeilstein Journal of Organic Chemistry, 2018
The efficient CO2 fixation by N-benzyl cyclic guanidine 1 was achieved by bubbling dry CO2 through CH3CN at 25 °C for 2 h. In addition, the zwitterion adduct 2 and bicarbonate salt 3 were selectively prepared from 1 under dry (in anhydrous CH3CN) and wet
