20-May-2015 | Hong Liu; Yan Xiao; Heng Xu; Yebin Guan; Jun Zhang; Meidong Lang, Chemical Communication, 2015
Rationally designed polypeptides with similar molecular structure but varying patterns of hydrogen bonding between side groups have been synthesized and demonstrated to possess distinct solubility and thermal behavior. Further balancing the ratio of both isopropylamine and ethylenediamine side ...
20-May-2015 | Cristina Mottillo; Tomislav Friščić, Chemical Communication, 2015
While azolate anions have been extensively used as anionic linkers in framework design, we now demonstrate the synthesis of square-grid networks that utilise their cationic analogues, imidazolium ions, as linkers. The resulting imidazolium frameworks are direct hydrogen-bonded analogues of ...
20-May-2015 | Marc-André Courtemanche; Alex Pulis; Étienne Rochette; Marc-André Légaré; Douglas W Stephan; Frederic-Georges Fontaine, Chemical Communication, 2015
The FLP species 1-BR2-2-NMe2-C6H4 (R = 2,4,6-Me3C6H2 1, 2,4,5-Me3C6H2 2) react with H2 in sequential hydrogen activation and protodeborylation reactions to give (1-BH2-2-NMe2-C6H4)2 3. While 1 reacts with H2/CO2 to give formyl, acetal and methoxy-derivatives, 2 reacts with H2/CO2 to give ...
13-May-2015 | Naimin Shao; Tianjiao Dai; Yan Liu; Yiyun Cheng, Chemical Communication, 2015
Cyanuric acid is able to form complementary hydrogen bonds with melamine. Here, the specific recognition between cyanuric acid and melamine is used to significantly improve the gene transfection efficacy of low generation dendrimer via a supramolecular approach.
08-May-2015 | Kamran Qadir; Bui Thi Phuong Quynh; Hyosun Lee; Song Yi Moon; Sang Hoon Kim; Jeong Y. Park, Chemical Communication, 2015
Engineering Metal-oxide interfaces in TiO2-nanoporous (np) Au inverse catalyst results in enhancement of H2 oxidation activity. While intrinsic activity of novel np-Au prepared from Au-Si alloy is low, the activity increased as the weight fraction of the TTIP (amount of TiO2) was increased to 0.5 ...
07-May-2015 | Seongmin Park; Dongwook Lim; Yongwon Seo; Huen Lee, Chemical Communication, 2015
The stability of hydrate frameworks is influenced by guest molecules capable of hydrogen bonding with surrounding water molecules. Four remarkable features from the ammonium fluoride incorporation into a crystalline hydrate matrix provide important information on the thermodynamic stability, ...
07-May-2015 | Robert W. Newberry; Brett VanVeller; Ronald T. Raines, Chemical Communication, 2015
To probe noncovalent interactions within the collagen triple helix, backbone amides were replaced with a thioamide isostere. This subtle substitution is the first in the collagen backbone that does not compromise thermostability. A triple helix with a thioamide as a hydrogen bond donor was found ...
07-May-2015 | Chunyong He; Juzhou Tao, Chemical Communication, 2015
Small size molybdenum carbides (2.5 nm for MoC and 5.0 nm for Mo2C) with clean surface on graphene were prepared for efficient and stable hydrogen evolution reaction catalysts.
06-May-2015 | Y. Wang; Y. Nie; W. Ding; S. G. Chen; K. Xiong; X. Q. Qi; Y. Zhang; J. Wang; Z. D. Wei, Chemical Communication, 2015
The Co nanoparticles encapsulated inside Co and nitrogen co-doped carbon catalysts with small particle size and homogenous distribution of Co NPs were elaborately synthesized, which exhibit evidently outstanding activity and stability toward ORR/HER.
29-Apr-2015 | Bora Seo; Hu Young Jeong; Sung You Hong; Alla Zak; Sang Hoon Joo, Chemical Communication, 2015
Tungsten oxide/tungsten sulfide (W18O49@WS2) core–shell nanorods prepared via a controlled sulfidization reaction of W18O49 nanowhiskers showed hydrogen evolution reaction (HER) activity superior to WS2 nanotubes, indicating the critical role of a highly conductive oxide core in enhancing HER ...
