[Materials] Encapsulation of Hydrophobic Phthalocyanine with Poly(N-isopropylacrylamide)/Lipid Composite Microspheres for Thermo-Responsive Release and Photodynamic Therapy
Phthalocyanine (Pc) is a type of promising sensitizer molecules for photodynamic therapy (PDT), but its hydrophobicity substantially prevents its applications. In this study, we efficiently encapsulate Pc into poly(N-isopropylacrylamide) (pNIPAM) microgel particles, without or with lipid decoration (i.e., Pc@pNIPAM or Pc@pNIPAM/lipid), to improve its water solubility and prevent aggregation in a...

Octagonal prism shaped lithium iron phosphate composite particles as positive electrode materials for rechargeable lithium-ion battery
For the first time, octagonal prism shaped lithium iron phosphate (LiFePO4) composite particles supported on the multi-walled carbon nanotubes (MWNTs) (denoted as OP-LiFePO4/MWNTs) are prepared by using a boiling reflux assisted calcination method. Interestingly, spherical LiFePO4 composite particles (indexed as S-LiFePO4/C) are produced by the same procedure in the presence...

Correlation between hierarchical structure of crystal networks and macroscopic performance of mesoscopic soft materials and engineering principles
This review examines how the concepts and ideas of crystallization can be extended further and applied to the field of mesoscopic soft materials. It concerns the structural characteristics vs. the macroscopic performance, and the formation mechanism of crystal networks. Although this subject can be discussed in a broad sense across the area of mesoscopic soft materials, our main f...

【Journal of Materials Chemistry B】High-efficiency immunoassay platform with controllable surface roughness and oriented antibody immobilization
Abstract:
High-efficiency immunoassay platforms with controlled surface roughness (single- and dual-scale structured surface) were prepared by combining a facile layer-by-layer particle deposition approach with oriented immobilization of antibodies through boronic acid moieties. The as-prepared surfaces showed significantly enhanced antibody loading capacity and antigen recognition, as proven...

【Materials Letters】Preparation of size-tunable, highly monodisperse particles by self-assembly of N-phthaloylchitosan-g-polycaprolactone molecular bottle brushes
A series of amphiphilic N-phthaloylchitosan-g-polycaprolactone (PHCS-g-PCL) molecular bottle brushes were prepared by "graft onto" method. The narrow distribution of polycaprolactone (PCL) side chains ensures that the molecular bottle brushes can self-assemble into particles with a narrow size distribution in aqueous solution. The size of the self-assembled polymeric particles can be tuned by thre...

Super long-life supercapacitor electrode materials based on hierarchical porous hollow carbon microcapsules
Remarkable supercapacitor electrodes with a high specific supercapacitance and a super long cycle life
were achieved by using hierarchical porous hollow carbon microcapsules (HPHCMs) as active materials.
HPHCMs were prepared by a facile chemical route based on pyrolysis of a soft sacrificial template
involving a non-crosslinked core of poly(styrene-r-methylacrylic acid) and a crosslinke...

【Journal of Materials Chemistry B】Infection-resistant styrenic thermoplastic elastomers that can switch from bactericidal capability to anti-adhesion
Abstract:
Styrenic thermoplastic elastomers (STPEs), particularly for poly(styrene-b-isobutylene-b-styrene) (SIBS),have aroused great interest in the indwelling and implant applications. However, the biomaterialassociated infection is a great challenge for these hydrophobic elastomers. Here, benzyl chloride (BnCl) groups are initially introduced into the SIBS backbone via Friedel–C...

Effects of layering sequence on thermal response of multilayer fibrous materials: Unsteady-state cases
Heat transfer between multilayer fibrous materials under unsteady-state conditions is regarded as an intricate and unpredictable process, and the system thermal response with different layer stacking sequences is investigated in this paper. All six possible sequences for three-layer fabrics are measured by an apparatus set up in our lab and simulated by the finite element method, taking account of...

Effects of layer stacking sequence on temperature response of multi-layer composite materials under dynamic conditions
Individual slabs of different types are used to form composites with either 2- or 3-layer of various stacking sequences so as to examine whether stacking order has any influence on the thermal response of the composite samples under dynamic conditions. The excess temperature profile θ(x, t) of a laminated composite slab is first derived by Green’s function (GF) method so that the adiabatic surfa...
