The de-inking ability of the crude laccase (benzenediol: oxygen oxidoreductase, EC 1.10.3.2) produced by a white rot fungus Peniophora sp. (NFCCI-2131) was tested using mixed office waste paper. In addition, the impact on physical and optical properties of the de-inked pulp, and the chemical load of the effluent generated during laccase based de-inking process was also analyzed. In the present study, 2.5 U/ml laccase was produced by the fungus under submerged culture conditions. Laccase (10 U/g of air dried pulp) was found to improve the tensile strength of recycled pulp by 1.7-fold, de-inking efficiency by 1.5-fold, opacity by 3.84%, and brightness by 5.83%. Scanning electron microscopy analysis revealed less rupturing of cellulose fibers and increased detachment of ink particles from the surface of the fibers in comparison to chemical de-inking. Fourier-transform infrared spectroscopy analysis of laccase treated pulp revealed degradation of the guaiacyl group and a high degree of deformation in methyl group of lignin. The biochemical and chemical oxygen demand (BOD and COD) were found to be reduced by 52 and 36% respectively, in the effluent generated after crude laccase based de-inking of mixed office waste.

Double-cable conjugated polymers with near-infrared (NIR) electron acceptors are synthesized for use in single-component organic solar cells (SCOSCs). Through the development of a judicious synthetic pathway, the highly sensitive nature of the 2-(3-oxo-2,3-dihydroinden-1-ylidene)malononitrile (IC)-based electron acceptors in basic and protonic solvents is overcome. In addition, an asymmetric design motif is adopted to optimize the packing of donor and acceptor segments, enhancing charge separation efficiency. As such, the new double-cable polymers are successfully applied in SCOSCs, providing an efficiency of over 10 % with a broad photo response from 300 to 850 nm and exhibiting excellent thermal/light stability. These results demonstrate the powerful design of NIR-acceptor-based double-cable polymers and will enable SCOSCs to enter a new stage.

Cytokines mediate and control immune and inflammatory responses. Complex interactions exist between cytokines, inflammation and the adaptive responses in maintaining homeostasis, health, and well being. On-demand, local delivery of anti-inflammatory drug molecules to target tissues provides a means for effective drug dosing while reducing the adverse effects of systemic drug delivery. This work demonstrates a proof-of-concept theranostic approach for inflammation based on analyte-kissing induced signaling, whereby a drug (in this report, aspirin) can be released upon detection of a target level of a proinfammatory cytokine(i.e. Interferon-γ (IFN-γ)) in real time. The structure-switching aptamer based biosensor described here is capable of quantitatively and dynamically detecting IFN-γ both in vitro and in vivo with a sensitivity of 10 pg mL-1. Moreover, the released aspirin triggered by the inflammatory cytokine IFN-γ is able to inhibit inflammation in the inflammatory rat model, and the releasing of aspirin can be quantitatively controlled. Herein research provides a novel and promising strategy for in vivo detection of proinflammatory cytokines and the subsequent therapeutic delivery of anti-inflammatory molecules. This universal theranostic platform is expected to achieve great potentials on personalized medicine towards treatment of various of diseases and health conditions. © 2019, The Authors.

Hybrid adsorbents for COcapture were prepared by coassembling laponite（LP） nanosheets and 1-nbutyl-3-methylimidazolium chloride（BMIMCl）. The prepared BMIMCl/LP layered hybrids were systematically characterized. The interlayer distance of the BMIMCl/LP layered hybrids expanded with an increasing concentration of BMIMCl, indicating that cumulative BMIMCl was intercalated into the LP layers. The efficiency of BMIMCl toward COcapture was significantly enhanced after it was immobilized within LP layers.

High efficiency (EQE=30.15%) organic light emitting diode (OLED) was demonstrated by lightly doping the thermally activated delayed fluorescence (TADF) emitter (0.5%) into the TADF host, resulting from: (1) efficient energy transfer from host to dopant, (2) long exciton diffusion length in host, and (3) rare concentration quenching due to lightly-doped condition.
