The development of highly efficient and robust biomimetic catalysts is an essential and feasible strategy to overcome the intrinsic drawbacks of natural enzymes. Inspired by the synthetic strategy of covalent organic frameworks, we adopted a covalent-bond-driven strategy to prepare polyoxometalate (POM) based open fra…
While views on crystal nucleation throughout the 20 th century were dominated by classical nucleation theory (CNT), in which the ordered nucleus forms directly from monomeric species, observations over the past two decades across scientific fields have revealed a plethora of multistep nucleation processes, often invol…
In the field of biomedicine, tissue bio-adhesives require the use of polymer materials with integrated functions to meet changing practical applications. However, the currently available tissue glues cannot balance mechanical properties and biocompatibility. Inspired by the conversion of lipoic acid from small molecul…
Transparent glass ceramic embedded with Ba 4 Y 3 F 17 : Yb 3+ , Er 3+ nanocrystals can be realised as a promising temperature sensor.
Unprecedented excited-state nanothermometry with high sensitivity and low temperature uncertainty is proposed by combining the red-shift of V–O charge-transfer bands and a thermal coupling effect.
T cells, a concomitant decrease in regulatory T (Treg) cells, and an increased expression of the cytokines IFN-γ and TNF-α. Therefore, the immunochemotherapy using CDDP and MET mediated by this dual prodrug co-assembled nano-platform might provide a promising treatment strategy against lung cancer.
Functionalized cerium oxide nanoparticle (CeNP)-loaded fibro-porous poly-l-lactic acid (PLLA)/gelatin composite membranes were prepared via an electrospinning technology. Considering the importance of such membrane scaffolds for promoting angiogenesis in tissue engineering and drug screening, a series of PLLA/gelatin…
Upconversion nanoparticles (UCNPs) exhibit unique optical properties such as photo-emission stability, large anti-Stokes shift, and long excited-state lifetimes, allowing significant advances in a broad range of applications from biomedical sensing to super-resolution microscopy. In recent years, progress on nanoparti…
Long range electrical conduction in biomaterials is an increasingly active area of research, which includes systems such as the conductive pili, proteins, biomacromolecules, biocompatible conductive polymers and their derivatives. One material of particular interest, the human skin pigment melanin, is a long range pro…
, where the background signals dominate. Herein, we present a rigorous comparison of normal Raman and surface-enhanced Raman spectra for atomically defined surfaces of Au(111) or Au(100) with and without molecular adsorbates. It is clearly shown that the origin of the background continuum is well explained by a local…
Biomass-derived vinyl lactone acrylic bioplastics not only exhibit higher thermostability but also depolymerize more selectively to monomers with higher yield and purity compared to their petroleum-based vinyl ester acrylic counterpart.
(*COH)] is proposed as a descriptor to establish a relationship with the catalytic activity. Our rational design principles and rapid screening methods may shed light on the development of other highly efficient CORR electrocatalysts, as well as the other electrochemical systems.
In this work, we identify and characterize a new intriguing capability of carboxylated cellulose nanofibrils that could be exploited to design smart nanomaterials with tuned response properties for specific applications. Cellulose nanofibrils undergo a multivalent counter-ion induced re-entrant behavior at a specific…

Pt/Ga2O3 exhibited high activity for dehydrogenative coupling of methane into ethane (2CH4 → C2H6 + H2) in a fixed-bed flow reactor at 25 °C under 254 nm UV irradiation. The C2H6 formation was negligible at CH4 pressure of 10 kPa, but it was linearly increased with an increase in the pressure to 300 kPa.

For 0 ≤λ < 0.5, the derived hindrance factor quantifies the extent to which diffusion of finite-size tracers through the materials is hindered compared with free diffusion in the bulk liquid. The hindrance factor con…
The thermal stabilization of blue phases is a subject that has been of scientific and technological interest since their discovery. Meanwhile, carbonaceous nanomaterials such as C60 fullerenes, carbon nanotubes and graphene have generated interdisciplinary interest spanning across solid-state physics, organic chemistr…
Compartmentalization is a fundamental principle in biology that is needed for the temporal and spatial separation of chemically incompatible reactions and biomolecules. Nano- or micro-sized compartments made of synthetic polymers are used to mimick this principle. The self-assembly of these polymers into vesicular obj…
