Dendrimers have shown great promise as carriers in drug delivery due to their unique structures and superior properties. However, the precise control of payload release from a dendrimer matrix still presents a great challenge. Stimuli-responsive dendrimers that release payloads in response to a specific trigger could…
Insulating hexagonal boron nitride suppresses the electrochemical corrosion and provides a more effective long-term corrosion barrier than graphene.
Organic upconversion is a unique process in which low-energy light (usually NIR light) is converted to high-energy light through either the two-photon absorption (TPA) mechanism or the triplet-triplet annihilation (TTA) mechanism. Both TPA upconversion (TPA-UC) and TTA upconversion (TTA-UC) have been actively investig…
Two microporous CTFs with triptycene (TPC) and fluorene (FL) have been synthesized through a mild AlCl <sub>3</sub> -catalyzed Friedel–Crafts reaction, with the highest surface area of up to 1668 m <sup>2</sup> g <sup>−1</sup> for non-ionothermal CTFs. CTF-TPC and CTF-FL show an excellent carbon dioxide uptake capacit…
Nitride semiconductors have properties suitable for solar energy conversion and can be synthesized using high-energy precursors.
This study demonstrates the use of 3D Ni <sub>3</sub> N/carbon cloth nanosheets as electrode materials for lithium ion batteries and supercapacitors.
High-mobility perovskite BaSnO3 films are of significant interest as new wide bandgap semiconductors for power electronics, transparent conductors, and as high mobility channels for epitaxial integration with functional perovskites. Despite promising results for single crystals, high-mobility BaSnO3 films have been ch…
A strong pyro-catalytic dye degradation with an ultrahigh degradation efficiency (>99%) in hydrothermally synthesized pyroelectric BiFeO3 nanoparticles was achieved under a room-temperature cold-hot alternating excitation (between 27 °C to 38 °C). The pyro-catalysis originated from a combination of the pyroelectric ef…
Solid-liquid interfaces have received considerable attention in recent years due to their central role in many technologically relevant fields like electrochemistry, heterogeneous catalysis and corrosion. As the chemical processes in these examples take place primarily at the interface, understanding the structural an…
The heterostructure of silicene and graphene can serve as a promising anode material for lithium- and sodium-ion batteries.
Flexible and transparent supercapacitors, as advanced energy storage devices, are essential for the development of innovative wearable electronics because of their unique optical and mechanical qualities. However, all previous designs are based on carbon-based nanostructures like carbon nanotubes and graphene, and the…
cross-linking. The final bioactivity of collagen scaffolds is a result of both processes. By considering each step of fabrication, scaffolds can be tailored for the specific needs of each tissue, improving their therapeutic potential.
Two-dimensional transition metal dichalcogenides provide a unique platform to study excitons in confined structures. Recently, several important aspects of excitons in these materials have been investigated in detail. However, the formation process of excitons from free carriers has yet to be understood. Here we repor…
Recently, many theranostic nanomaterials have been developed by integrating therapeutic and diagnostic agents in a single regimen. Real-time visualization of nano drug carrier biodistributions, drug release processes and therapeutic responses can provide critical information needed for dynamically optimizing treatment…
The formation mechanism of graphene quantum dots (GQDs) from a graphene oxide (GO) precursor is elucidated and the inter-conversion of edge states in GQDs by annealing under a controlled gas environment is studied by various microscopic and spectroscopic tools.
An electrospun fiber of polyvinyl(pyrrolidone) (PVP)-Tween 20 (T20) with curcumin as the encapsulated drug has been developed. A study of intermolecular interactions was performed using Raman spectroscopy, Fourier transform infrared (FT-IR), differential scanning calorimetry (DSC), and X-ray diffraction (XRD). The Ram…
The increasing worldwide oil pollution intensifies the needs for new techniques of separation of oil from oily water.
The last few years have witnessed significant advances in the use of light as a stimulus to control biomolecular interactions. Great efforts have been devoted to the development of genetically encoded optobiological and small photochromic switches. Newly discovered small molecules now allow researchers to build molecu…
Heteroatom doped carbon dots (CDs) have received increasing attention due to their unique properties and related applications. However, previously reported CDs generally show strong emission only in the blue-light region, thus restricting their further applications. And the fundamental investigation on the preparation…
Nickel oxide (NiO) nanoparticles were synthesized through sol-gel method. The solution was controlled at pH 11 and the calcination temperature at 450 °C. The structure, morphology, and particles size of NiO were investigated. Structural analysis confirmed that the cubic structure of NiO was formed without impurity. Mo…
