Porous isostructural [Ln(BTC)(H2O)·4.3H2O], or Ln–BTC (Ln: Ce, Tb, and Y; BTC stands for 1,3,5‐benzenetricarboxylate), with a tetragonal structure has been synthesized by ultrasonic irradiation at room temperature. Under ultrasound, the syntheses were quickly accelerated to obtain the fully crystallized phase in only minutes. The particle size can be considerably decreased by this method. On the basis of XRD, field‐emission scanning electron microscopy (FE‐SEM), and surface area analyses, it can be understood that the Ln–BTCs are homogeneous in phase, isostructural, and microporous. The synthesis rates are rCe–BTC > rTb–BTC > rY–BTC for both in the nucleation and crystal‐growth stages, thereby illustrating the importance of the lability of the metal ions in the synthesis of the metal‐organic framework (MOF) materials. The Tb–BTC shows luminescence properties, a characteristic property of Tb3+ (green‐light emission), in the range of 470–630 nm at room temperature. It is believed that these lanthanide MOFs with micropores and/or luminescent properties should be proven to be multifunctional materials on further investigations.

Developmental rates of Aculops lycopersici increased linearly as rearing temperature increased. A total of 81.2 degree-days above a developmental zero of 10.5°C were required to complete development from egg to adult emergence. Adult longevity decreased with increasing temperature. The highest intrinsic rate of natural increase was observed at 25°C as 0.253 per day. The population increased exponentially on greenhouse tomato plants and the intrinsic rate of natural increase was estimated to be 0.175 per day. A. lycopersici first reproduced on the released leaves then moved upward. The infestation caused great injury to the plants, with a large number of leaves turning brown and then drying up. The number of leaves, the plant height and the diameter of the main stem of the plants all decreased. Homeopronematus anconai naturally occurred on tomato plants. After the rapid population increase of H. anconai, the A. lycopersici population decreased sharply. An adult H. anconai consumed an average of 69.3 A. lycopersici deutonymphs per day in the laboratory. H. anconai was thought to be a prospective natural enemy of A. lycopersici.

The effect of constant temperature on the development, reproduction and population growth of Aculops lycopersici reared on a tomato leaflet was investigated. Survival rates from egg to adult were more than 69% at temperatures between 15°C and 27.5°C, but only 53% at 30°C. Developmental rates increased linearly as rearing temperature increased from 15°C to 27.5°C. A total of 81.2 degree-days above a developmental zero of 10.5°C were required to complete development from egg to adult emergence. Adult longevity decreased with increasing temperature. Fecundity was highest at 25°C with 51.7 eggs per female. The highest intrinsic rate of natural increase was observed at 25°C as 0.253 per day.

This article presents a theoretical investigation of the differential, integrated, elastic, inelastic, total, momentum-transfer, and viscosity cross-sections, along with the total ionization cross-section, for elastically scattered electrons and positrons from a carbon dioxide (CO2) molecule in the incident energy range of 1 eV ≤Ei≤ 1 MeV. In addition, for the first time, we report the spin polarization of e±−CO2 scattering systems. The independent atom model (IAM) with screening correction (IAMS) using a complex optical potential was employed to solve the Dirac relativistic equation in partial-wave analysis. The comparison of our results with the available experimental data and other theoretical predictions shows a reasonable agreement in the intermediate- and high-energy regions.
