Herein, perylene diimide (PDI)/oxygen-doped g-C3N4 nanosheets (O-CN) n-n heterojunction photocatalyst was prepared by an in-situ electrostatic assembling. The pi-pi interaction between self-assembled PDI and O-CN could lead to the electron delocalization effect to facilitate the electron migration. Self-assembled PDI could broaden the visible response range of O-CN to produce more photogenerated carries. Moreover, the interlaced band structures of O-CN and self-assembled PDI could result in a built-in electric field to promote the interfacial charge separation. Besides, many active species (h(+), O-center dot(2-) and O-1(2) ) could be accumulated to improve the oxidation ability of PDI/O-CN. Therefore, PDI/O-CN exhibited enhanced visible photocatalytic oxidation activities towards disinfection, degradation and oxygen evolution. The optimum PDI/O-CN inactivated 96.6% of Staphylococcus aureus cells within 3 h, while O-CN only killed 62.2%. Additionally, the phenol degradation rate and evolved oxygen amount in 2 h of PDI/O-CN-40% were 3.6 and 1.8 times as high as those of O-CN, respectively.

The novel flame retarded unsaturated polyester resins have been developed and prepared by introduction of high nitrogen content additives into the polymer matrix in order to verify their effectiveness in the formation of swollen carbonaceous char inhibiting the burning process of the polymer. The intumescent flame retardants (IFRs) based on mixture or metal complex were developed and characterized by particle size distribution, Fourier-transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), powder X-ray diffraction (XRD), elemental analysis (CHN) and thermogravimetric analysis (TGA). The evaluation of the efficiency of IFRs addition on the flammability and smoke emission of the unsaturated polyester resins (UP) was carried out using the fire hazard (UL-94), limiting oxygen index (LOI) and cone calorimeter (CC) tests, as well as smoke density chamber tests. The volatile compounds evolved during the burning of materials were determined using a steady state tube furnace and a gas chromatograph with mass spectrometer. Furthermore, the prepared materials were subjected to differential scanning calorimetry (DSC), thermogravimetric analysis and water resistance tests. The mechanical properties of the materials were investigated using Shore D hardness and dynamic mechanical thermal analysis (DMA). The structural evaluation of the manufactured materials and samples after the cone calorimetry tests was carried out using scanning electron microscopy (SEM). It was found that the incorporation of new intumescent flame retardants led to the formation of carbonaceous char layers’ inhibiting the decomposition process and limiting the smoke emission. The most promising results were obtained for the resin containing complex designated as ZN3AT, for which the highest reduction in maximum values of heat release rate (419 kW/m(2)) compared to unmodified polymer (792 kW/m(2)) were recorded. Apart from that, the prepared intumescent flame retardants affect the cross-linking process as well as the thermal and mechanical properties of the UP.

Solvothermal reactions of Zn(NO3)(2)center dot 6H(2)O, 3-amino-1,2,4-triazole as well as three different carboxylate ligands afforded three novel coordination polymers: [Zn-2 (azdc) (atz) (OH) (H2O)](n) (1), {[Zn-1.5 (btc)(0.5) (atz)]center dot 1.5H(2)O}(n) (2), and {[Zn-4 (nipa)(2) (atz)(3)(OH) (H2O)]center dot 2H(2)O}(n) (3) (H(2)azdc = 4,4′-azobenzoic acid, H(4)btc = 1,2,4,5-benzenetetracarboxylic acid, 5-H(2)nipa = 5-nitroisophthalic acid, Hatz = 3-amino-1,2,4-triazole). Moreover, the three coordination polymers have been characterized by IR spectroscopy, elemental analysis, single-crystal X-ray diffraction, and powder X-ray diffraction techniques. Complex 1 reveals a 2D layer structure, which is further connected through pi-pi stacking interactions forming a 3D supramolecular network. Complex 2 exhibits a 3D porous framework with 1D open channels. Complex 3 shows a 3D pillared-layer framework. Notably, the thermal decomposition processes of 1-3 were investigated by simultaneous TG-DSC techniques. The TG curves reveal that complexes 1-3 possess pretty good thermostability up to 321 degrees C, 416 degrees C and 418 degrees C, respectively. The apparent activation energy E (E-1 = 194.975 kJ mol(-1), E-2 = 220.360 kJ mol(-1), E-3 = 223.600 kJ mol(-1)) and the pre exponential factor A of skeleton collapse for the complexes 1-3 were calculated by the integral Kissinger’s method and Ozawa-Doyle’s method. The structural stability could be illustrated from the point of thermal decomposition kinetics.

A totally new theory of two-step stabilization mechanism for triazole-based zinc-containing complex (abbreviated as (Zn(ttr)(OAc)]) was proposed through several designed experiments. [Zn(ttr)(OAc)] strongly absorbed HCl at the beginning, and then broke down into 3-amino-1,2,4-triazole which could further stabilized PVC. The structure of [Zn(ttr)(OAc)] was characterized by FTIR spectroscopy, elemental analysis and SEM. Then, Congo red tests and discoloration tests verified [Zn(ttr)(OAc)] could absorb HCl effectively, but PVC showed poor initial whiteness, which further proved above -mentioned stabilization mechanism. Moreover, [Zn(ttr)(OAc)] combined with ZnSt(2) and dibenzoyl methane (DBM) effectively improved the initial color of PVC samples and provided PVC with shorter plasticizing time and longer dynamic thermal stability time than commercial stabilizer 1086F, confirmed by discoloration tests and dynamic thermal stability analysis. We believe [Zn(ttr)(OAc)]/ZnSt(2)/DBM stabilizer system can be used as a commercial stabilizer and the stabilization mechanism of [Zn(ttr)(OAc)] may provide a new way to stabilize PVC.

Drug-like inhibitors are often designed by mimicking cofactor or substrate interactions with enzymes. However, as active sites are comprised of conserved residues, it is difficult to identify the critical interactions needed to design selective inhibitors. We are developing an approach, named RADD (resistance analysis during design), which involves engineering point mutations in the target to generate active alleles and testing compounds against them. Mutations that alter compound potency identify residues that make key interactions with the inhibitor and predict target-binding poses. Here, we apply this approach to analyze how diaminotriazole-based inhibitors bind spastin, a microtubule-severing AAA (ATPase associated with diverse cellular activities) protein. The distinct binding poses predicted for two similar inhibitors were confirmed by a series of X-ray structures. Importantly, our approach not only reveals how selective inhibition of the target can be achieved but also identifies resistance-conferring mutations at the early stages of the design process.

An effectively Zn/Zn stabilizer system instead of traditional Ca/Zn stabilizer system was put forward, which contained a new triazole-based zinc-containing complex (abbreviated as [Zn(ttr)(St)]) and Zinc stearate (ZnSt(2)). Without Ca soap in the system, [Zn(ttr)(St)] itself could effectively absorb HCl and provided PVC with higher transparency and better thermal stability without zinc burning than commercial CaSt(2)/ZnSt(2) stabilizer system, verified by Congo red tests and discoloration tests and dynamic thermal stability analysis. In addition, [Zn(ttr)(St)] could further delay zinc burning of other zinc soaps, constituting Zn/Zn stabilizer system. This is attributed to the strong ability of restricting ZnCl2 of 3-amino-1,2,4-triazole released from [Zn(ttr)(St)] after absorbing HCl. After adding ESBO, PVC stabilized by [Zn(ttr)(St)]/ZnSt(2)/ESBO showed excellent transparency and thermal stability. We believe that [Zn(ttr)(St)] can act as a novel double agent with the stabilization effects of zinc soap and calcium soap at the same time and this Zn/Zn stabilizer system may inaugurate a new stabilizer system for PVC with synergistic effect.

A new energetic coordination polymer (ECP) composite, namely GO-Cu(II)-AmTZ, has been synthesized by 3-amino-1,2,4-triazole (AmTZ) and multifunctional graphene oxide (GO) coordination with Cu(II) successively. The ECP composite was further characterized through SEM, EDS and XPS analysis as well as FTIR and Raman spectroscopy. It shows high thermostability, high decomposition heat release and insensitivity to mechanical stimuli. What’s more, thermal analysis data for ammonium perchlorate (AP) have been obtained by mechanically mixing GO-Cu(II)-AmTZ and AP. The low-temperature decomposition (LTD, 335.3 degrees C) and high-temperature decomposition (HTD, 441.3 degrees C) peaks of AP were reduced to an exothermic peak at 298.4 degrees C at a heating rate of 10 degrees C min(-1). GO-Cu(II)-AmTZ exhibits outstanding catalytic performance by decreasing the activation energy from 168.7 kJ mol(-1) to 122.4 kJ mol(-1), indicating its promising application as a combustion catalyst for improving the thermal-catalytic decomposition performance of energetic materials largely. In addition, thermal analysis techniques including thermogravimetry coupled with mass spectrometry (TG/MS) and thermogravimetry coupled with infrared spectrometry (TG/IR) were employed to determine the decomposition mechanisms.

A colorimetric and visual assay is described for the herbicide aminotriazole (ATZ). It is based on the etching of gold nanorods (AuNRs) by iodine which is formed on oxidation of iodide via H2O2. Longitudinal etching of the AuNRs occurs quickly and is accompanied by a color change from dark blue to red. In the absence of ATZ and the presence of active catalase (CAT), H2O2 is quickly decomposed into water, and the AuNRs will not be etched. In thepresence of ATZ, CAT is partially deactivated, and this affects the amount of available H2O2 and, consequently, of the iodine. Hence, the color is significantly changed. The color changes can be easily detected with bare eyes. The assay has a linear response in the 5 to 70 mu M concentration range, with a detection limit of 1.3 mu M and high selectivity for ATZ. It was applied to the determination of ATZ in water and food samples.
