Charge excitations across an electronic band gap play an important role in opto-electronics and light harvesting. In contrast to conventional semiconductors, studies of above-band-gap photoexcitations in strongly correlated materials are still in their infancy. Here we reveal the ultrafast dynamics controlled by Hund'…
The adsorption of formic acid (FA) and the formation of formate species on metal oxide surfaces are of great interest in catalysis. Formic acid is used to probe the adsorption properties of surface sites, and formates are common intermediates in many catalytic reactions. Here we focus on the interaction of FA with a p…
Abstract Polyaniline (PANI)/MXene composites have been widely studied for high performance supercapacitors because of the combination of the electric double layer capacitance and pseudocapacitance. In this paper, dl-tartaric acid (DLTA) was first assembled on the surface of MXene to achieve supramolecular self-assembl…
Surface modification of nanofibrillated bacterial cellulose (NFBC) with methyltrimethoxysilane was performed in water to hydrophobize its surface. A series of cellulose samples with different degrees of molar substitution of methyltrimethoxysilane was prepared by changing the NFBC:methyltrimethoxysilane ratio in the p…
In this work, we report a robust Ru phosphide (RuP) catalyst, which exhibits high propylene selectivity for propane dehydrogenation, whereas monometallic Ru nanoparticles (NPs) result in cracking. X-ray photoelectron spectroscopy, synchrotron X-ray absorption spectroscopy, transmission CO-IR of the reduced catalyst, a…
The unique electrochemical properties of the conductive polymer poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) make it an attractive material for use in neural tissue engineering applications. However, inadequate mechanical properties, and difficulties in processing and lack of biodegradability hav…
Malignant tumors represent some of the most intractable diseases that endanger human health. A glioma is a tumor of the central nervous system that is characterized by severe invasiveness, blurred boundaries between the tumor and surrounding normal tissue, difficult surgical removal, and high recurrence. Moreover, the…
A luminescent lanthanide-titanium oxo cluster of Eu 2 Ti 4 (μ 2 -O) 2 (μ 3 -O) 4 (phen) 2 (tbza) 10 ·4CH 3 CN ( 1, Eu 2 Ti 4 -phen-tbza, phen = 1,10-phenanthroline, Htbza = 4- tert -butylbenzoic acid) was prepared through the reaction of phen, Htbza, Eu(Ac) 3 · x H 2 O, and Ti(O i Pr) 4 in acetonitrile. Its overall ab…
Due to the ultrathin thickness and dangling-bond-free surface, 2D materials have been regarded as promising candidates for future nanoelectronics. In recent years, group-VI elemental 2D materials have been rediscovered and found superior in electrical properties (e.g., high carrier mobility, high photoconductivity, an…
Abstract Fundamental dynamic processes at the electronic contact interface, such as carrier injection and transport, become pivotal and significantly affect device performance. Time-resolved photoemission electron microscopy (TR-PEEM) with high spatiotemporal resolution provides unprecedented abilities of imaging the…
Taking advantages of aqueous electrolytes such as high safety, ease of fabrication, and high ion conductivity, a series of aqueous batteries have been reported, including lithium-ion batteries, sodium-ion batteries, zinc-ion batteries, aluminum-ion batteries, and novel batteries such as ammonium batteries. They realiz…
Pristine and engineered metal nanoparticles are widely applied in various fields of industry, and as consequences, they are useful as well as harmful to human health and environment. This study aimed at synthesizing the green zinc oxide nanoparticles (ZnNPs) using the leaf extract of Ocimum sanctum Linn and assessing…
Imparting and maintaining surface superhydrophobicity has been receiving significant research attention over the last several years, driven by a broad range of important applications and enabled by advancements in materials and surface nanoengineering. Researchers have investigated the effect of temperature on droplet…
The present study is aimed to access the photodegradation efficiency of methylene blue dye using CoFe2O4 and Co0.1Al0.03Fe0.17O0.4 nanoparticles. The synthesis of spinel ferrites nanoparticles was performed by a facile sol-gel method. The synthesized nanoparticles were characterized by FTIR, XRD, SEM, EDS, Nitrogen ad…
The downsides of conventional cancer monotherapies are profound and enormously consequential, as drug-resistant cancer cells and cancer stem cells (CSC) are typically not eliminated. Here, a targeted theranostic nano vehicle (TTNV) is designed using manganese-doped mesoporous silica nanoparticle with an ideal surface…
Self-sorting double network hydrogels comprising orthogonal supramolecular nanofibers have attracted attention as artificially-regulated multi-component systems. Regulation of network patterns of self-sorted nanofibers is considered as a key for potential applications such as optoelectronics, but still challenging owi…
Ten years ago, we issued an open prediction challenge to the cheminformatics community: would participants be able to predict the equilibrium intrinsic solubilities of 32 druglike molecules using only a high-precision (CheqSol instrument, performed in one laboratory) set of 100 compounds as a training set? The "solubi…
