Xiang Yun Debbie Soo, Danwei Zhang, Sze Yu Tan, Yi Ting Chong, more

Advanced Materials > 36 > 36 > n/a - n/a

Thermochromic materials are substances that change color in response to temperature variations. Today, sustainability concerns are the main drivers of thermochromic research, with smart, energy‐efficient windows being one of the primary applications. While vanadium oxides and leuco dyes are traditionally the main thermochromic materials, hydrogels operating based on change of solvation have risen...

Addiction Biology > 29 > 7 > n/a - n/a

Benzodiazepine (BZD) dependence poses a significant challenge in mental health, prompting the exploration of treatments like repetitive transcranial magnetic stimulation (rTMS). This research aims to assess the impact of rTMS on alleviating symptoms of BZD dependence. A randomized control trial was employed to study 40 BZD‐dependent inpatients. Their symptoms were quantified using the Hamilton Anxiety...

Controllable Ceramic Green‐Body Configuration for Complex Ceramic Architectures with Fine Features

Danwei Zhang, Erwin Peng, Ramadan Borayek, Jun Ding

Advanced Functional Materials > 29 > 12 > n/a - n/a

Fabrication of dense ceramic articles with intricate fine features and geometrically complex morphology by using a relatively simple and the cost‐effective process still remains a challenge. Ceramics, either in its green‐ or sintered‐form, are known for being hard yet brittle which limits further shape reconfiguration. In this work, a combinatorial process of ceramic robocasting and photopolymerization...

Ceramic Robocasting: Recent Achievements, Potential, and Future Developments

Erwin Peng, Danwei Zhang, Jun Ding

Advanced Materials > 30 > 47 > n/a - n/a

Additive manufacturing (AM) of ceramic materials has attracted tremendous attention in recent years, due to its potential to fabricate suitable advanced ceramic structures for various engineering applications. Robocasting, a subset of ceramic AM, is an ideal technique for constructing fine and dense ceramic structures with geometrically complex morphology. With the freedom and convenience to deposit...

Enhanced visible-light driven photocatalytic activity of hybrid ZnO/g-C3N4 by high performance ball milling

Qin Chen, Huijie Hou, Danwei Zhang, Shaogang Hu, more

Journal of Photochemistry and Photobiology A: Chemistry > 2018 > 350 > C > 1-9

The ZnO/g-C₃N₄ photocatalyst was prepared by ball milling and demonstrated enhanced photocatalytic degradation of RhB under visible light irradiation. The photocatalyst is consisted of ZnO and g-C₃N₄ heterojunctions formed by the shear stress during the mechanical treatment. The addition of g-C₃N₄ can improve the photocatalytic performance of ZnO under visible light. The heterojunction formed between...

Embedment of Well Dispersed Nickel Nanoparticles in Sulfonate and Benzimidazole Functionalized Poly (Arylene Ether Ketone) Film for the Electrocatalytic Oxidation of Glucose

Lingling Xi, Tengfei Wang, Danwei Zhang

Electroanalysis > 29 > 12 > 2689 - 2697

Stable and well dispersed nickel nanoparticles (NiNPs) were fabricated and embedded in a novel polymer sulfonate and benzimidazole functionalized poly (arylene ether ketone) (S‐BI‐PAEK) film. After drop‐casting the mixed solution of S‐BI‐PAEK and NiSO₄ on glassy carbon electrode (GCE) surface, the uniformly distributed NiNPs were formed and stably embedded in S‐BI‐PAEK film by in‐situ electrochemical...

Cover Picture: Aromatic Amide Polymers that Form Two Helical Conformations with Twist Sense Bias in Water (Chin. J. Chem. 7/2016)

Peng Zhang, Zekun Wang, Liang Zhang, Hui Wang, more

Chinese Journal of Chemistry > 34 > 7 > 649 - 649

The cover picture shows that benzene/2,2′‐bipyridine‐alternately incorporated amide polymers are driven by hydrophobicity to form two helical conformations both of which exhibit helicity bias. Switching between the two helical conformations can be tuned by the coordination of the 2,2′‐bipyridine units to Ni²⁺ ions. More details are discussed in the article by Li et al. on page 678–682.

Aromatic Amide Polymers that Form Two Helical Conformations with Twist Sense Bias in Water

Peng Zhang, Zekun Wang, Liang Zhang, Hui Wang, more

Chinese Journal of Chemistry > 34 > 7 > 678 - 682

Two benzene/2,2′‐bipyridine‐alternately incorporated amide polymers have been prepared, which are driven by hydrophobicity to form two different helical conformations. Both helices exhibit twist sense bias in water induced by chiral valine side chains and the coordination of the 2,2′‐bipyridine unit to the Ni²⁺ ions.

Layer-by-layer assembly of poly(p-aminobenzene sulfonic acid)/quaternary amine functionalized carbon nanotube/p-aminobenzene sulfonic acid composite film on glassy carbon electrode for the determination of ascorbic acid

Lingling Xi, Danwei Zhang, Fengli Wang, Zhongping Huang, more

Journal of Electroanalytical Chemistry > 2016 > 767 > C > 91-99

An excellent p-aminobenzene sulfonic acid (p-ABSA) monolayer film was fabricated on glassy carbon electrode (GCE) by situ electrochemical oxidation. Then a novel kind of homogeneous quaternary amine-functionalized carbon nanotube (q-CNT) film was adsorbed onto p-ABSA/GCE through electrostatic interaction to produce q-CNT/p-ABSA/GCE. Finally an electropolymerized poly(p-ABSA) film was formed on q-CNT/p-ABSA/GCE...

Natural gas pricing reform in China: Getting closer to a market system?

Sergey Paltsev, Danwei Zhang

Energy Policy > 2015 > 86 > C > 43-56

Recent policy in China targets an increase in the contribution of natural gas to the nation's energy supply. Historically, China's natural gas prices have been highly regulated with a goal to protect consumers. The old pricing regime failed to provide enough incentives for natural gas suppliers, which often resulted in natural gas shortage. A new gas pricing reform was tested in Guangdong and Guangxi...

Co-benefit of polycrystalline large-scale photovoltaic power in China

Da Zhang, Songlin Tang, Bao Lin, Zhen Liu, more

Energy > 2012 > 41 > 1 > 436-442

Recognized as an indispensable player in the future electricity supply mix of China, photovoltaic (PV) power has experienced a fast expansion in recent years. Owing to the higher cost compared with traditional coal-fired power, financial subsidy is crucial for the development of PV power. Although a series of policies have been implemented to subsidize PV power, strong and steady policies to stimulate...

N-H…X (X = F, Cl, Br, and I) hydrogen bonding in aromatic amide derivatives in crystal structures

DongYun Wang, JiLiang Wang, DanWei Zhang, ZhanTing Li

Science China Chemistry > 2012 > 55 > 10 > 2018-2026

Intramolecular N-H…X (X = F, Cl, Br, and I) hydrogen bonding patterns of aromatic amides in the solid state are summarized. It is revealed that the key for the formation of this kind of weak intramolecular hydrogen bonding in X-ray crystal structures is to suppress the competition of strong intermolecular N-H…O-C hydrogen bonding of the amide unit. For amides with identical backbones, the bonding...
