Tofu-inspired microcarriers from droplet microfluidics for drug delivery
Science in China Series B: Chemistry - Tập 62 - Trang 87-94 - 2018
Microcarriers have attracted increasing interests in drug delivery. In order to
develop this technique, it is prone to focus on the generation of functional
particles through using simple approaches and novel but accessible materials.
Here, inspired by the formation mechanism of tofu that through the mixing of
soymilk and brine for cross-linking soybean proteins, we present novel soybean
protein m...
A reaction-and-assembly approach using monoamine zinc porphyrin for highly stable large-area perovskite solar cells
Science in China Series B: Chemistry - Tập 63 - Trang 777-784 - 2020
Inhibiting the irreversible escape of organic cations and iodide species in
perovskite films is crucial for the fabrication of efficient and stable
perovskite solar cells (PSCs). Here, we develop a reaction-and-assembly approach
using monoamine zinc porphyrin (ZnP) to modify methylammonium (MA+) lead iodide
perovskite film. The amine group in ZnP reacts with MA+ and I− ions to yield
monoammonium z...
Trisubstituted alkenes featuring aryl groups: stereoselective synthetic strategies and applications
Science in China Series B: Chemistry - Tập 66 - Trang 1261-1287 - 2023
In recent years, the synthesis and application of alkenes have attracted
increased attention. Triphenylethenes (TriPEs) have lower molecular torsion than
tetraphenylethenes (TPEs), which helps to balance the degree of conjugation and
the aggregation-induced emission (AIE) effect. The geometry of double bonds has
a significant impact on luminescence. Therefore, it is essential to provide a
comprehe...
Radical cascade reactions of unsaturated C-C bonds involving migration
Science in China Series B: Chemistry - Tập 62 - Trang 1476-1491 - 2019
During the past few years, with the rapid development of mild methods for the
generation of radical species, great progress in radical cascade reactions of
unsaturated C-C bonds has been made. Many radical cascade reactions involve
functional groups migration, which leads structurally much more diverse, complex
and valuable compounds not easily obtained through other methods. In this
review, the r...
Improving the sensitivity for DNA sensing based on double-anchored DNA modified gold nanoparticles
Science in China Series B: Chemistry - Tập 59 - Trang 765-769 - 2016
DNA modified nanoparticles (AuNPs) are an established and widely used type of
nucleotide sensor. We sought to improve the design by applying short rigid DNA
duplexes near the surface of the AuNPs forming a so called double-anchored AuNP
sensor, and compared it with other conventional DNA modified AuNPs. The improved
design exhibited higher assembly efficiency, and consequently increased its
sensit...
A theoretical study of hydrothermal stability of P-modified ZSM-5 zeolites
Science in China Series B: Chemistry - - 2009
Density functional theory was employed to study the hydrothermal stability of
P-modified ZSM-5 zeolites using cluster models. The calculations of hydrolysis
energies indicated that the introduction of phosphorus increases the
hydrothermal stability of ZSM-5 zeolites. The initial paths of dealumination
were studied with explicit water molecules. It was found that the framework Al-O
coordination bon...
Highly sensitive potentiometric immunosensor for hepatitis B surface antigen diagnosis
Science in China Series B: Chemistry - Tập 48 - Trang 49-57 - 2005
A highly sensitive potentiometric immunosensor for the diagnoses of epidemic
diseases has been developed by means of self-assembly to immobilize hepatitis B
surface antibody (HBsAb) for the detection of hepatitis B surface antigen
(HBsAg) as a model. At first, the Nafion containing ™SO 3 ™ groups was
immobilized on a platinum electrode surface to absorb the ™NH3 + groups of
antibody moleculesvia t...
Cấu hình lại bề mặt perovskite thông qua phản ứng bổ sung R4NBr nhằm tạo ra các tế bào năng lượng mặt trời FAPbI3 hiệu quả và ổn định Dịch bởi AI
Science in China Series B: Chemistry - Tập 65 - Trang 1185-1195 - 2022
Các trạng thái khuyết tật trong các lớp phim perovskite hạn chế tính ổn định
giao diện và điện áp hở mạch của các tế bào năng lượng mặt trời perovskite.
Trong nghiên cứu này, nhằm đạt được tính passivation giao diện ưu việt, chúng
tôi điều tra việc tái cấu trúc giao diện perovskite bằng sự tương tác giữa một
loạt các bromide amoni tứ trị (QAB) và octahedron chì-halide (Pb-X). Phản ứng
thay thế bro...
Numerical simulation of Marangoni effects of single drops induced by interphase mass transfer in liquid-liquid extraction systems by the level set method
Science in China Series B: Chemistry - Tập 51 - Trang 684-694 - 2008
The mathematical model of mass transfer-induced Marangoni effect is formulated.
The drop surface evolution is captured by the level set method, in which the
interface is represented by the embedded set of zero level of a scalar distance
function defined in the whole computational domain. Numerical simulation of the
Marangoni effect induced by interphase mass transfer to/from deformable single
drop...
Hierarchical metal-peptide assemblies with chirality-encoded spiral architecture and catalytic activity
Science in China Series B: Chemistry - Tập 66 - Trang 228-241 - 2022
We report the coordination assembly of the ferrocene-diphenylalanine (Fc-FF)
with divalent copper ions (Cu2+) into metal-peptide assemblies (MPAs) with
hierarchical spiral architectures. The MPA particles are composed of helically
organized nanofibers which can be correlated to the logarithmic spirals. The
MPAs are hierarchically porous with abundant Fc and Cu2+ active sites and show
much higher c...
