KY Lin, YF Yeh, YS Hsu, JY Wu, KL Yang… - … and Design Education, 2022 - Springer

Previous research has analyzed the meaning and value of STEM education and explored both its current possibilities and future development. However, STEM education experts have not reached a consensus on the goals of STEM education, making its promotion more...

Solvothermal synthesis of orthorhombic Sb2WO6 hierarchical structures and their visible-light-driven photocatalytic activity.

Dalton transactions (Cambridge, England : 2003)

Hu SP, Xu CY, Ma FX, Cao L, Zhen L.
PMID: 24741676
Dalton Trans. 2014 Jun 14;43(22):8439-45. doi: 10.1039/c3dt53561d. Epub 2014 Apr 17.

We report the solvothermal synthesis of hierarchical structures of orthorhombic Sb2WO6 and their implementation as a visible-light-driven photocatalyst for the degradation of Rhodamine B. The obtained hierarchical structures constructed by tiny nanosheets are doughnut-like flat ellipsoids with concaves in...

Ultrahigh mobility and efficient charge injection in monolayer organic thin-film transistors on boron nitride.

Sci Adv. 2017 Sep 06;3(9):e1701186. doi: 10.1126/sciadv.1701186. eCollection 2017 Sep.

Organic thin-film transistors (OTFTs) with high mobility and low contact resistance have been actively pursued as building blocks for low-cost organic electronics. In conventional solution-processed or vacuum-deposited OTFTs, due to interfacial defects and traps, the organic film has to...

New Labdane diterpenes from Hedychium yunnanense with cytotoxicity and inhibitory effects on nitric oxide production.

Natural product research

Li YP, Zhao SM, Xu JJ, Zeng GZ, Li Y, Tan NH, Yang Y.
PMID: 26965832
Nat Prod Res. 2016 Dec;30(23):2669-2674. doi: 10.1080/14786419.2016.1143829. Epub 2016 Mar 11.

Two new labdane diterpenes, hedychenoids A (1) and B (2), were isolated from the rhizomes of Hedychium yunnanense, together with four known ones hedychenone (3), forrestin A (4), villosin (5) and calcaratarin C (6). Their structures were determined on...

Controlled Growth of a Large-Size 2D Selenium Nanosheet and Its Electronic and Optoelectronic Applications.

ACS nano

Qin J, Qiu G, Jian J, Zhou H, Yang L, Charnas A, Zemlyanov DY, Xu CY, Xu X, Wu W, Wang H, Ye PD.

ACS Nano. 2017 Oct 24;11(10):10222-10229. doi: 10.1021/acsnano.7b04786. Epub 2017 Sep 28.

Selenium has attracted intensive attention as a promising material candidate for future optoelectronic applications. However, selenium has a strong tendency to grow into nanowire forms due to its anisotropic atomic structure, which has largely hindered the exploration of its...

Supramolecular Interfacial Polymerization: A Controllable Method of Fabricating Supramolecular Polymeric Materials.

Angewandte Chemie (International ed. in English)

Qin B, Zhang S, Song Q, Huang Z, Xu JF, Zhang X.
PMID: 28480605
Angew Chem Int Ed Engl. 2017 Jun 19;56(26):7639-7643. doi: 10.1002/anie.201703572. Epub 2017 May 24.

A new method of supramolecular polymerization at the water-oil interface is developed. As a demonstration, an oil-soluble supramonomer containing two thiol end groups linked by two ureidopyrimidinone units and a water-soluble monomer bearing two maleimide end groups are employed....

Intrathecal rapamycin attenuates morphine-induced analgesic tolerance and hyperalgesia in rats with neuropathic pain.

Translational perioperative and pain medicine

Xu JT, Sun L, Lutz BM, Bekker A, Tao YX.
PMID: 26339682
Transl Perioper Pain Med. 2015;2(2):27-34.

Repeated and long-term administration of opioids is often accompanied by the initiation of opioid-induced analgesic tolerance and hyperalgesia in chronic pain patients. Our previous studies showed that repeated intrathecal morphine injection activated the mammalian target of rapamycin complex 1...
