The study focused on the mesophilic anaerobic hydrogen production from PPS (pulp and paper sludge)and FW (food waste) pretreated by NaOH or H2SO4, and the subsequent thermophilic anaerobic methane production with the effluent in a two-stage process. The maximum hydrogen yield (78.35 mL gˉ1 VSfed)which was 50.21% higher than that of CK, was achieved when 10 g NaOH/100 g TSsubstrate was used. However, the maximum methane yield (383.8 mL gˉ1 VSfed) was obtained in CK as well as 64% SCOD removal efficiency was achieved. In short, NaOH/H2SO4 pretreatment was suitable to enhance the hydrogen production.

In recent years, unmanned underwater vehicles (UUV) have been vigorously developed, and with the continuous deepening of marine exploration, traditional energy can no longer meet the energy supply. Nuclear energy can achieve a huge and sustainable energy supply. The heat pipe reactor has no flow system and related auxiliary systems, and the supporting mechanical moving parts are greatly reduced, the noise is relatively small, and the system is simpler and more reliable. It is more favorable for the control of unmanned systems. The use of heat pipe reactors in unmanned underwater vehicles can meet the needs for highly compact, long-life, unmanned, highly reliable, ultra-quiet power supplies. In this paper, a heat pipe reactor scheme named UPR-S that can be applied to unmanned underwater vehicles is designed. The reactor core can provide 1 MW of thermal power, and it can operate at full power for 5 years. UPR-S has negative reactive feedback, it has inherent safety. The temperature and stress of the reactor are within the limits of the material, and the core safety can still be guaranteed when the two heat pipes are failed.

This work focused on developing an approach to reusing digested deinking sludge for corrugatingmedium paper manufacture by recycling secondary fibers. The fiber content in the digested deinkingsludge (DDS) was around 41.87%, and the main proportion of fibers (87.6%) was subject to secondaryfines with lengths less than 0.2 mm. The qualified corrugating medium paper was obtained when thesecondary fiber load from DDS was equal or less than 30%. Corrugating medium paper manufactured byadding DDS could maximize reuse and recycling of deinking sludge via methane and papermakingmaterial production, and reduce the environmental pollution as well.

This paper focused on the ammonium removal from the digested effluent of swine wastewater (DESW) via MAP precipitation using the residue from magnesium-hydroxide flue gas desulfurization (MFGD) process as a Mg source. The MAP precipitation was proceeded in a 500-mL beaker with a magnetic stirrer. It was found that around 60% of ammonium in the DESW was removed at pH 9.5, HRT 10 min and the P:Mg:N molar ratio of 0.6:0.7:1. The NH4+ concentration (183.2 mg/L) in the DESW after MAP precipitation was lower than 200 mg L−1, being alternative for the downstream biological process. A low content of PO43− (3.64 mg L−1) and a high concentration of Mg2+ (67.17 mg L−1) were also observed in the solution. The main composition of the precipitate was proved to be MAP via XRD and SEM-EDX analysis. Besides, the total chemical cost was saved by 29.17% using the MFGD residue as a Mg source instead of the commercial MgCl2·6H2O. Hence, reusing MFGD residue as a Mg source to remove ammonium from the DESW was feasible with cost saving, resource recovery and environment protection.

A new dye intermediate and novel reactive dyes containing both azo and benzsulfonamide auxochromic groupswere synthesized. Their structures were characterized by 1H-NMR, 13C-NMR, MS, IR, and UV-Vis spectral analysis. Thesynthesized dyes were applied to dyeing of cotton fabrics and their dyeing parameters were assessed. The new dyes exhibitedimproved substantivity and fixation property on cotton fabrics compared with the dye C.I. Reactive Black 5 (RB5). Themaximum exhaustion and total fixation values of the reactive dyes appeared when 2 % owf of the dye concentration wasused. The wash fastness and rub fastness of the new dyes reached up to 4 grade and 4-5 grade, respectively. In addition, theyshowed excellent fastness to light. These new dyes seem to be promising candidates for application to dyeing of cotton fibers.

<P>Three-dimensional visualization identifies structural remodeling in chloroplasts during barley stripe mosaic virus infection.</P><P>Chloroplasts are multifunctional organelles whose morphology is affected by environmental stresses. Although the three-dimensional (3D) architecture of thylakoid membranes has been reported previously, a 3D visualization of chloroplast under stress has not been explored. In this work, we used a positive-strand RNA ((+)RNA) virus, barley stripe mosaic virus (BSMV) to observe chloroplast structural changes during infection by electron tomography. The analyses revealed remodeling of the chloroplast membranes, characterized by the clustering of outer membrane-invaginated spherules in inner membrane-derived packets. Diverse morphologies of cytoplasmic invaginations (CIs) were evident with spherules at the periphery and different sized openings connecting the CIs to the cytoplasm. Immunoelectron microscopy of these viral components verified that the aberrant membrane structures were sites for BSMV replication. The BSMV αa replication protein localized at the surface of the chloroplasts and played a prominent role in eliciting chloroplast membrane rearrangements. In sum, our results have revealed the 3D structure of the chloroplasts induced by BSMV infection. These findings contribute to our understanding of chloroplast morphological changes under stress conditions and during assembly of plant (+)RNA virus replication complexes.</P>
