A highly porous bio-MOF, medi-MOF-1, constructed from Zn and the pharmaceutical ingredient curcumin has been successfully synthesized. It can display permanent porosity with a surface area as high as ca. 3002 m(2) g(-1), which exhibits great potential in bioapplications. Its ibuprofen delivery ability, biodegradation…
Supramolecular systems formed by the binding of several cyclodextrins (CDs) to polymers or lipids, either via non-covalent or covalent links, open a wide range of possibilities for the delivery of active substances. CDs can perform as multifunctionalizable cores to which very diverse (macro)molecules and drugs can be…
It is important to reduce the recombination of electrons and holes and enhance charge transfer through fine controlled interfaces for advanced catalyst design. In this work, graphene oxide (GO) was composited with graphitic-C3N4 (g-C3N4) and BiOI forming GO/g-C3N4 and GO/BiOI heterostructural interfaces, respectively.…
It has been shown that ingestion of microplastics may increase bioaccumulation of organic chemicals by aquatic organisms. This paper critically reviews the literature on the effects of plastic ingestion on the bioaccumulation of organic chemicals, emphasizing quantitative approaches and mechanistic models. It appears…
The adsorption properties of layered double hydroxide (Mg/Al-CO3) for the removal of Congo Red (CR) dye from aqueous solution were studied. The layered double hydroxide was synthesized by co-precipitation method and characterized by X-ray diffraction (XRD), Fourier Transform Infrared spectroscopic (FTIR) and Energy-Di…
A new metal–organic framework analogue is stable under ambient conditions with the ability to remove toxic gases.
biological evaluations reveal that this biocompatible functional system exhibits a noticeable level of selectivity for cancer cells overexpressing β-galactosidase.
Thin silver film coated nanobowl Surface Enhanced Raman Spectroscopy (SERS) substrates are used to capture exosomes in solution for SERS measurements that can provide biochemical analysis of intact and ruptured exosomes. Exosomes derived via Total Exosome Isolation Reagent (TEIR) as well as ultracentrifugation (UC) fr…
Superior to silica nanoparticles, the easily accessible and removable CaCO 3 particles produced porous carbon nitride with photocurrents 7.5-times that of the bulk one.
An electrochemical sensing platform based on a hydrothermally synthesized rGO–Co 3 O 4 @Pt nanocomposite was developed for the detection of in situ generated NO.
Reversible aluminum intercalation/deintercalation from an organic electrolyte into copper hexacyanoferrate is presented. Evidence suggest that an aluminum-solute complex is the intercalating species. The system shows initial discharge capacities as high as 60 mA h g(-1) and reversible capacities between 5 and 14 mA h…
Developing safe and effective nanoprobes for targeted imaging and selective therapy of gastric cancer stem cells (GCSCs) has become one of the most promising anticancer strategies. Herein, gold nanostars-based PEGylated multifunctional nanoprobes were prepared with conjugated CD44v6 monoclonal antibodies (CD44v6-GNS)…
The objective of this Feature Article is to reflect on the importance of established and emerging principles of supramolecular organic chemistry to address one of the most persistent problems in life sciences. The main topic is dynamic covalent chemistry on cell surfaces, particularly disulfide exchange for thiol-medi…
Organic-inorganic hybrid perovskite solar cells have emerged as cost effective efficient light-to-electricity conversion devices. Unravelling the time scale and the mechanisms that govern the charge carrier dynamics is of paramount importance for a clear understanding and further optimization of the perovskite based d…
Two symmetrical biphenyl monomers derived from vanillin, a methylated divanillyl diol and a methylated dimethylvanillate dimer, were synthesized and employed as (co)monomers for the design of renewable (semi)aromatic polyesters.
In situ Raman and surface-enhanced Raman scattering (SERS) are established vibrational spectroscopic techniques with a wide range of applications in the field of chemical, material and life sciences. Their particular characteristics make them especially useful when dealing with catalytic water oxidation at anodes. The…
The search for low-cost, highly active, and stable catalysts to replace the Pt-based catalysts for oxygen reduction reaction (ORR) has recently become a topic of interest. Herein, we report a new strategy to design a nitrogen-doped carbon nanomaterial for use as a metal-free ORR catalyst based on facile pyrolysis of p…
displays field-induced slow magnetic relaxation, which is rare for monometallic Ni(ii) complexes due to efficient spin-lattice and quantum tunnelling relaxation pathways.
Self-healing concrete has been scrutinized by several researchers and some industrial concrete producers in relation to the remediation of the occurrence of micro-cracks. Such cracks are a quite well known problem that can lead to corrosion of the steel reinforcement and thus to the possible failure of the entire conc…
We report the addition of a small amount of Pb(SCN)2 into PbI2 in a two-step solution method. The resulting CH3NH3PbI(3-x)(SCN)x perovskite films present larger-sized crystals and fewer traps than CH3NH3PbI3. Their planar solar cells exhibit a maximum power conversion efficiency of 11.07% with remarkably high reproduc…
