Liquid hydrogen carriers featuring high hydrogen content, safety, and hydrogen release on demand have motivated great endeavors for sustainable hydrogen supply. Nonetheless, direct hydrogen release is limited by the ultralow hydrogen evolution rate, while the conventional manner of extra additive and solvent addition for promoting rates greatly deteriorates its hydrogen storage density. Thus, it is...
The possibility to precisely control important properties of nanoparticles (NPs) such as their size, morphology, surface charge, or doping content is crucial for enhancing the performance of existing solutions beyond the state‐of‐the‐art and for enabling novel applications. In this work, custom‐tailored ZnxFe3−xO4 NPs are synthesized at different Zn doping concentrations to augment and expand their...
Controlling the morphology, composition, and crystalline phase of mesoporous nonnoble metal catalysts is essential for improving their performance. Herein, well‐defined P‐ and B‐codoped NiFe alloy mesoporous nanospheres (NiFeB‐P MNs) with an adjustable Ni/Fe ratio and large mesopores (11 nm) are synthesized via soft‐template‐based chemical reduction and a subsequent phosphine‐vapor‐based phosphidation...
The configurational complexity and distinct local atomic environments of high entropy oxides remain largely unexplored, leaving structure‐property relationships and the hypothesis that the family offers rich tunability for applications ambiguous. This work investigates the influence of cation size and materials synthesis in determining the resulting structure and magnetic properties of a family of...
Polysulfide shuttling and sluggish sulfur redox kinetics hinder the cyclability and rate capability of lithium–sulfur (Li–S) batteries. The intrinsic redox kinetics of sulfur cathodes strongly depends on the interaction between catalysts and sulfur species. Herein, N‐doped CoTe2 is proposed as an effective dual‐anchoring electrocatalyst, which can simultaneously bind Li and S atoms in lithium polysulfides...
The huge consumption of single‐use plastic straws has brought a long‐lasting environmental problem. Paper straws, the current replacement for plastic straws, suffer from drawbacks, such as a high cost of the water‐proof wax layer and poor water stability due to the easy delamination of the wax layer. It is therefore crucial to find a high‐performing alternative to mitigate the environmental problems...
The electrochemical synthesis of mesoporous ruthenium (Ru) films using sacrificial self‐assembled block polymer micelles templates, and its electrochemical surface oxidation to RuOx is described. Unlike standard methods such as thermal oxidation, the electrochemical oxidation method described here retains the mesoporous structure. Ru oxide materials serve as high‐performance supercapacitor electrodes...
3D printing of lignocellulosic biomass (cellulose, hemicellulose, and lignin) has attracted increasing attention by using this abundant, sustainable, and ecofriendly material. While cellulose can be easily tailored into a highly viscous ink for 3D printing, after solvent evaporation, the final printed structures become highly porous, fragile, and easily fall apart in water due to its hydrophilic nature...
Selective hydrogenation of nitriles is an industrially relevant synthetic route for the preparation of primary amines. Amorphous metal–boron alloys have a tunable, glass‐like structure that generates a high concentration of unsaturated metal surface atoms that serve as active sites in hydrogenation reactions. Here, a method to create nanoparticles composed of mesoporous 3D networks of amorphous nickel–boron...
The arterial microenvironment plays a vital role in the pathology of atherosclerosis (AS). However, the interplay between the arterial microenvironment and atherogenesis remains unclear, partially due to the gap between cell culture and animal experiments. Addressing this problem, the present study reports a microfluidic AS model reconstituting early‐stage AS. Physiological or AS‐prone hemodynamic...
On page 2022, a microfluidic atherosclerosis (AS) model reconstituting early‐stage AS is designed by X. Jiang and co‐workers. Physiological or AS‐prone hemodynamic conditions are recapitulated on the model. Under a hemodynamic background, AS‐prone biochemical factors such as hyperglycemia, hyperlipidemia, angiotensin‐II, tumor necrosis factor‐α (TNF‐α) and lipopolysaccharides lead to dysfunction of...
