A selective intracellular free radical generation strategy against cancer cells is developed by lysosomal bioactivation of a prodrug/procatalyst co-delivery nanosystem.
We use a meso-scale dissipative particle dynamics method to simulate the flow and aggregation of rod-like protein solutions through pores grafted with a solvent-sensitive polymer brush. The coated pores can control protein permeability and aggregation by a stretch-to-collapse conformational transition of the brush pol…
Photo-unclick chemistry mediates visible and near IR-controlled drug release via a singlet oxygen (SO)-cleavable linker. Due to the limited diffusion distance of SO in biological systems, a photosensitizer and the SO-cleavable linker have been conjugated in one molecule or mixed in nano-drug delivery systems. In this…
Electrically driven near-infrared light-emission from individual heavily Ga-doped ZnO microwires has been achieved, which can be analogous to incandescent sources.
Long, stable, and free-standing linear atomic carbon chains and boron nitride (BN) chains have been carved out from their 2D sheets recently [Meyer <italic>et al.</italic> , <italic>Nature</italic> , 2008, <bold>454</bold> (7202), 319; Jin <italic>et al. Phys. Rev. Lett.</italic> , 2009, <bold>102</bold> (20), 205501;…
Synthesis of C-Dots from waste paper has been successfully created. A total of 5 grams of waste paper is mixed with 40 mL aquades, 30 mL H2SO4 and 50 mL NaOH 2 M. A precursor solution is prepared by adding urea in 20 ml of material. Synthesis of C-Dots done by heating the precursor hydrothermally using a furnace with…
A generic and universal layer engineering strategy for van der Waals (vW) materials, scalable and compatible with the current semiconductor technology, is of paramount importance in realizing all-two-dimensional logic circuits and to move beyond the silicon scaling limit. In this letter, we demonstrate a scalable and…
We report a chiral molecular packing with α-helical tubules, and chiral symmetry-breaking upon exposure to metal ions that generated the final ordered structure <italic>via</italic> an <italic>in situ</italic> morphological transition without undergoing any phase change.
Upconversion magnetic nanoparticles emit visible light after NIR irradiation. Gd renders them with MRI contrast. Localization of the particles is excellently visible in blood vasculature of tumor bearing mice after intravenous administration.
Cancer research has experienced astonishing advances recently, but cancer remains a major threat because it is one of the leading causes of death worldwide. Glioblastoma (GBM) is the most malignant brain tumor, where the early diagnosis is vital for longer survival. Thus, this study reports the synthesis of novel wate…
Silver grid printed on ITO film through EHD jet printing as a transparent conducting electrode improves electrochromic performances of soft ECDs.
A novel functionalized POSS greatly reinforced the mechanical, thermal stability, and flame retardant properties of PBT.
In this chapter, the development of efficient GdIII-based agents for MRI is detailed. This chapter is divided into ten sections covering the general theory of the relaxivity of GdIII-based contrast agents; the measurement of longitudinal (T1) and transverse (T2) relaxation times; the theory, acquisition, and interpret…
This study was conducted to prepare coaxial electrospun scaffolds of P3HB4HB/(gelatin + PVA) with various concentration ratios with P3HB4HB as the core solution and gelatin + PVA mixture as the shell solution; the mass ratios of gelatin and PVA in each 10 mL shell mixture were 0.6 g : 0.2 g (Group A), 0.4 g : 0.4 g (G…
In this study, a cell-free bone tissue engineering scaffold based on core-sheath fibers with micro/submicro-scale structures were fabricated for bone regeneration. The composite fibers were prepared by coaxial electrospinning with cellulose acetate (CA) core solution and a sheath solution consisting of a mixture of si…

hpz = diprotonated homopiperazine) exhibits a distinct room-temperature dielectric transition. The dielectric switching at 303 K is associated with an order-disorder transition of the polar guest cation confined in the cage, corresponding to a dynamic change between motional and frozen states.
, which is well recognized as the Menshutkin reaction. This research provides insights into the dependence of the cluster structure on the nature of the ligand and into the cluster formation mechanism of the Menshutkin reaction.
A series of Fe <bold>L3</bold> complexes of dipyridyl β-diketones were structurally characterized and their catalytic properties investigated.
The neutron diffraction method was adopted to study the three-dimensional residual stress distribution in SiC bulk crystals for the first time.
