Entirely oligosaccharide-based supramolecular amphiphiles constructed via host–guest interactions as efficient drug delivery platforms
-β-CD). The amphiphiles could self-assemble to form spherical supramolecular nanoparticles to provide efficient drug delivery platforms. The combination of a pH-sensitive covalent acetal group and the oxidation-sensitive noncovalent host-guest interaction of β-CD and ferrocene provided the obtained fully oligosacchari…
Peptide Supramolecular Self-Assembly:Structural Precise Regulation and Functionalization
Biomolecular self-assembly plays a significant role for physiological function. Inspired by this, the construction of functional structures and architectures by biomolecular self-assembly has attracted tremendous attentions. Peptides can be assembled into diverse nanostructures, exhibiting important potential for biom…
Dual-responsive ALS-type organogelators based on azobenzene–cholesteryl conjugates and their self-assemblies
Azobenzene and cholesteryl based derivatives ( <bold>N2</bold> and <bold>N4</bold> ) were designed as gelators and their aggregation mechanism is proposed. These gelators are thermally reversible, however optically irreversible.
Structural transformation of Pd-α-Fe 2 O 3 and Pd-γ-Fe 2 O 3 catalysts and application in the CO oxidation reaction
Pd-α-Fe <sub>2</sub> O <sub>3</sub> and Pd-γ-Fe <sub>2</sub> O <sub>3</sub> catalysts can be obtained by redox pretreatment and exhibit different reactive performances during CO oxidation.
A dual-functional surface with hierarchical micro/nanostructure arrays for self-cleaning and antireflection
A dual-functional surface with patterned hierarchical micro/nanostructure arrays has been fabricated by femtosecond laser and thermal oxidation.
Effect of Indium nano-sandwiching on the structural and optical performance of ZnSe films
In the current study, we attempted to explore the effects of the Indium nanosandwiching on the mechanical and optical properties of the physically evaporated ZnSe thin films by means of X-ray diffractions and ultraviolet spectrophotometry techniques. While the thickness of each layer of ZnSe was fixed at 1.0 μm, the t…

Photoinduced electron transfer (PET)-mediated fluorescence quenching of CdTe/CdS quantum dots by pralidoxime (PAM).
The role of various oxygen species in Mn-based layered double hydroxide catalysts in selective alcohol oxidation
Precise identification of oxygen species in LDH-based catalysts was investigated for the first time for alcohol oxidation.
Structural and physical–chemical behavior of a CeO 2 nanoparticle based diesel additive during combustion and environmental release
The colloidal and chemical stability of CeO <sub>2</sub> nanoparticles used in a diesel additive ( <italic>viz.</italic> Envirox™) was studied at different stages of their lifecycle (formulation, use, end of life).
Polarization driven conductance variations at charged ferroelectric domain walls
by the combination of photoemission electron microscopy (PEEM) and second harmonic generation (SHG) microscopy. While SHG unveils the overall domain wall inclination angle α, PEEM is sensitive to local conductance variations, both at and away from the domain wall. Thus, the two imaging techniques deliver complementary…
Spontaneous emulsification and self-propulsion of oil droplets induced by the synthesis of amino acid-based surfactants
It is well known that oil droplets in or on water exhibit spontaneous movement induced by surfactants, and this self-propulsion is regarded as an important factor in droplet-based models for a living cell. We report here an oil-droplet system spontaneously producing amino acid-based surfactants, which are then utilize…
Nonergodicity parameters of confined hard-sphere glasses
Within a recently developed mode-coupling theory for fluids confined to a slit we elaborate numerical results for the long-time limits of suitably generalized intermediate scattering functions. The theory requires as input the density profile perpendicular to the plates, which we obtain from density functional theory…

Real-time storage of thermal signals in organic memory devices has been achieved with micro-contact printed Au@Pd core–shell nanoparticles floating on plastic substrates.
Enhanced durability of an iridium-bipyridine complex embedded into organosilica nanotubes for water oxidation
-pentamethylcyclopentadienyl) complex. The as-prepared Ir-BPy-NT catalyst showed enhanced durability with high reaction activity compared to the analogous homogeneous and the conventional heterogeneous ones, due to the stable nanotube structures as well as the isolated active sites. The unique one-dimensional nanotube…

Functionalization of any substrate using covalently modified large area CVD graphene
We report a novel route for the functionalization of any substrates, including chemically inert substrates. CVD grown graphene is electrochemically functionalized with p-(N-maleimido)phenyl residues and consecutively transferred to various substrates. The transfer process is shown to be without noticeable loss. The fu…
