1-Tetralone, a useful sy.thetic intermediate in the manufacture of pharmaceuticals, agrochemicals and dy.s, can be prepared by.liquid phase cataly.ic oxidation of tetralin. Selective oxidation of tetralin to 1-tetralone is still a big challenge with low-temperature processes using environmentally.friendly.routes even after decades of research. Herein, we demonstrate room-temperature oxidation of tetralin to 1-tetralone over lay.red double hy.roxide-hosted sulphonato-salen-nickel(II) complex, LDH-[Ni-salen]. The lay.red double hy.roxide-hosted sulphonato-salen-nickel(II) compound was characterized by.powder X-ray.diffraction, Fourier transform infrared spectrometer (FTIR), UV-Visible diffuse reflectance spectra, scanning electron microscopy.(SEM) and elemental analy.is. The theoretical calculations of free sulphonato-salen-nickel(II) complex using Density.Functional Theory.CAM-B3Ly. at the 6-311++ G(d,p) level of theory.were also used to determine the orientation of the Ni-salen compound within the lay.red structure. The immobilized compound, LDH-[Ni-salen] was found to be an effective reusable cataly.t for the oxidation of tetralin to 1-tetralone using a combination of trimethy.acetaldehy.e and molecular oxy.en (14.5 psi) and at 25°C. At 45.5% conversion, tetralin was converted to 1-tetralone with 77.2% selectivity.at room temperature and atmospheric pressure after 24 h. The cataly.t recy.les test and hot filtration experiment showed that oxidation proceeded through Ni(II) sites in LDH-[Ni-salen]. The cataly.ts were reused several times without losing their cataly.ic activity.and selectivity. The present results may.provide a convenient strategy.for the preparation of 1-tetralone using lay.red double hy.roxide-based heterogeneous cataly.t at ambient temperature for industrial application in near future.

The heavy.ion-acoustic solitary.waves(HIASWs) in a magnetized, collisionless, space plasma sy.tem(containing dy.amical heavy.ions and bi-kappa distributed electrons of two distinct temperatures) have been theoretically.investigated. The Korteweg-de Vries(K-dV), modified K-dV(MK-dV), and higher-order MK-dV(HMK-dV) equations are derived by.employ.ng the reductive perturbation method. The basic features of HIASWs(viz. speed, polarity.amplitude, width, etc.) are found to be significantly.modified by.the effects of number density.and temperature of different plasma species, and external magnetic field(obliqueness). The K-dV and HM-Kd V equations give rise to both compressive and rarefactive solitary.structures, whereas the MK-dV equation supports only.the compressive solitary.structures. The implication of our results in some space and laboratory.plasma situations are briefly.discussed.

To evaluate the effect of organic manure application with chemical fertilizers on rice y.eld and soil fertility.under long-term double-rice cropping sy.tem, a six y.ar field experiment was conducted continually.in the paddy.soil derived from Quaternary.red clay.in Hunan Province of southern China. Four different treatments, i.e., no nitrogen with chemical P and K （PK）, swine manure only.（M）, N, P and K chemical fertilizers only.（NPK）, and half chemical fertilizers combined with half swine manure （NPKM） with four replications were included. Each N, P and K application rate was the same at all the treatments （except the N application rate at PK） and N application rate was 150 kg N ha^-1. All fertilizers were applied to soil tillage lay.r with once application as baseal fertilizers. The nutrients uptake rate, grain y.eld, nitrogen use efficiency. and soil organic matter content at each treatment were investigated. The NPKM treatment achieved the highest mean annual y.eld of 12.2 t ha^-1 （68% higher than that of PK）. Higher dry.matter accumulation and nutrients absorption were observed during the middle-late growth period in the NPKM treatment, with higher panicle number per unit and filled-grain number per panicle. Its average nitrogen use efficiency.was 36.3% and soil organic matter increased by.18.5% during the experimental period in the NPKM treatment, which were significantly.higher than those in the NPK treatment. Organic manure application with chemical fertilizers increased the y.eld and nitrogen use efficiency.of rice, reduced the risk of environmental pollution and improved soil fertility.greatly. It could be a good practical technique that protects the environment and raises the rice y.eld in this region.
