Study of the performance of nitrogen-doped modified activated carbon as catalyst carrier for the selective catalytic reduction of NO with NH 3 at low temperatures
Xiangdong Feng, Shanjian Liu, Yongjun Li, Ranran Kong, Jianjie He Nitrogen-doped modified activated carbons (NACs) were prepared from coconut shell, date shell, and almond shell using the urea modification method. NO tests of NH3 selective catalytic reduction (NH3-SCR) were conducted to evaluate the efficiency of different types of nitrogen-doped modified AC as denitration catalyst carriers at 50–220°C. NACs denitrification activity tests were carried out in a fixed-bed reactor with an inner diameter of 15 mm and a total gas flow rate of 500 mL·min−1 flue gas....

Extremely bulky & #x3b2;-diketiminate complexes of calcium(ii) and ytterbium(ii)
Brant Maitland, Andreas Stasch, Cameron Jones The extremely bulky β-diketiminato calcium(ii) and ytterbium(ii) iodide complexes [(Ar*Nacnac)MI] (M = Ca or Yb) have been prepared. The reduction of [(Ar*Nacnac)CaI] with sodium metal yielded a ligand C–H activated product, while reaction of [(Ar*Nacnac)YbI] with K[HBEt3] gave an ytterbium(ii) borate contact ion pair (e.g. see picture).

Monometallic Ln 3+ and heterometallic Ln 3+ & #x2013;Cd 2+ complexes based on pentafluorophenylacetic acid: efficient control of dimension and luminescent properties & #x2020;

Eremenko New complexes of Eu3+ and Tb3+ with pentafluorophenylacetic acid have been studied. During synthesis under hydrothermal conditions, polymer structures are formed, while the introduction of phenanthroline and Cd2+ makes it possible to obtain molecular complexes. A change in the structure leads to significant changes in the luminescent properties. (Source: Australian Journal of Chemistry)

The role of silver carbonate as a catalyst in the synthesis of N-phenylbenzamide from benzoic acid and phenyl isocyanate: a mechanistic exploration
Yang Yang, Benjamin Spyrou, Paul S. Donnelly, Allan J. Canty, Richard A. J. O’Hair While gas-phase studies suggest that both silver-mediated extrusion-insertion (ExIn) and base-mediated condensation reactions operate for the generation of N-phenyl-benzamide anion from the benzoate anion, the condensation reaction is favoured in the solution phase.

Bochkarev New heteroleptic lanthanide complexes with oxybenzo[h]quinoline ligands were obtained and their photoluminescent (PL) properties were studied. The PL spectrum of the La compound contains phosphorescent bands with a lifetime over 10 ms. The complexes of Nd, Sm and Yb display metal-centered luminescent f–f transitions.

Effects of cryoprotectants on phospholipid monolayers & #x2013; concentration and species dependence
Rekha Raju, Juan Torrent-Burgués, Gary Bryant The interactions between four cryoprotectants and monolayers of four phospholipids were investigated. Significant differences are observed as functions of cryoprotectant, lipid species and physical state of the monolayer, highlighting that results based on a single model system are insufficient to understand the mechanisms of action of cryoprotectants.

Charge-transfer complexes of arylthiotetrathiafulvalenes and TCNQF 4 : their structural diversity and electronic states
Longfei Ma, Congjie Pan Charge-transfer (CT) complexes formed between Ar-S-TTFs and TCNQF4 are investigated. It is found that the complexes show different degrees of charge transfer and the stacking structures of the CT complexes can be manipulated by varying the symmetry and size of the aryl groups on the Ar-S-TTF.

Influence of Crystal Disorder in MoS 2 Cathodes for Secondary Hybrid Mg-Li Batteries
Jyah Strachan, Lu Chen, Thomas Ellis, Anthony Masters, Thomas Maschmeyer
The influence of morphological characteristics on the electrochemistry of MoS2 electrodes remains unclear. We show that introducing disorder decreases the Faradaic component of cell capacity and causes pseudo-capacitive behaviour. Post-annealing, the battery-like character of the cell is restored. The findings aid the optimisation of MoS2 electrodes, which are promising battery components. (Source: Australian Journal of Chemistry)

Folic Acid-Targeted MXene Nanoparticles for Doxorubicin Loaded Drug Delivery
Zhen Liu, Lan Xie, Jia Yan, Pengfei Liu, Huixiang Wen, Huijun Liu
A folate receptors-targeted drug carrier with high drug loading (69.9 %) and slow drug release time (48 h) was constructed based on the rich surface functional groups of MXenes. Tumour targeting and pH-responsive mechanism can make MXene nanoparticles quickly accumulate and release drugs in large quantities at tumour sites. (Source: Australian Journal of Chemistry)

Sialyltransferase Inhibitors as Potential Anti-Cancer Agents
Danielle Skropeta, Christopher Dobie, Andrew P. Montgomery, Harrison Steele, Rémi Szabo, Haibo Yu
Increased protein sialylation on the tumour cell surface of up to 40–60 % through upregulation of sialyltransferase enzymes is strongly correlated with tumour growth, survival, and metastasis. Inhibiting sialylation represents a potential new cancer treatment strategy. In this account, we summarise our recent developments on the design, synthesis, and biological evaluation of synthetically accessible sialylation inhibitors with improved properties over earlier-generation...
