Aqueous Zn–CO 2 battery possesses a large theoretical capacity of 820 mAh g -1 (5855 cm -3 ) and high safety, showing unique position in carbon neutrality and/or reduction energy conversion storage, which has developed rapidly recent years. However, obstacles such as low value-added products, current density, overvoltage, finite cycles impede its practical application. Cathode catalysts, key co...

It is wise to mimic a bioinspired system design nanoreactor as catalyst containing multiple components for cascade reaction. Here, we report the uniform growth of well-dispersed nano-scale ZIF-8 crystals on pore walls 3DOM TiO2 via TEA-assisted crystallization process. The UV-vis spectra indicate that photosensitizer can extend visible-light absorption TiO2. obtained efficiently catalyze one-po...

Developing environmentally friendly UV-curable polymers with multi-functionality is very significant for sustainable development and environmental protection. In this work, a novel tung-oil-based oligomer (TOMAH) was synthesized by Diels–Alder ring-opening reactions via microwave technology. Subsequently, catalyst-free self-healing materials based on maleate monoester transesterification (MMETE...

Severe surface photocarrier recombination and poor electronic conductivity are the major factors behind sluggish photoelectrochemical water oxidation kinetics of ZnFe2O4 photoanode. Here, CeOx catalyst overlayer has been coupled with reduced nanorods (NRs) to reduce charge on photoanode significantly. The density functional theory (DFT) studies indicate that oxygen vacancy defect-rich construct...

This paper argues that innovation can be best understood as an information process which is then concretized as a product that meets demand. Two very different firms, Canon Inc. and Apple Computer Inc., are used as case study illustrations. Innovation does not proceed through logical deduction, but rather is furthered by the use of metaphors and analogies. The bureaucratic and staid structures ...

The observation of Manchot? that sodium pentacyano-ammineferroate2 I absorbs oxygen has led Baudisch and his coworkers3 to study the catalytic action of this salt, as well as of its water analogue II, in the oxidation of pyrimidines and purines. The present authors have previously reported in this journal4 on the nature of the oxidation products obtained. In the present paper the problem is con...

BACKGROUND Conceptually, multi-functional enzymes are attractive because in the case of complex polymer hydrolysis having two or more activities defined by a single enzyme offers the possibility of synergy and reduced enzyme cocktail complexity. Nevertheless, multi-functional enzymes are quite rare and are generally multi-domain assemblies with each activity being defined by a separate protein ...

Outside Front Cover: Antibacterial activity based on the generation of reactive oxygen species (ROS) has been investigated. A doped metal oxide catalyst deposited by sputtering was postoxidized and covered a hydrophobic plasma polymer film, allowing diffusion water ROS. Rapid bacterial inhibition observed even during storage in dark, which can be reactivated light exposure. The developed multif...

A multifunctional coupler with an ethylene carbonate- and a thiolactone ring was synthesized. As proof of principle the coupler was reacted with four low-molecular weight building blocks to form a multifunctional molecule. The reactivity/selectivity of the coupler towards amines, acrylates and acyl halides was evaluated.
