Hybrid Functional Study on Electronic and Optical Properties of the Dopants in Anatase TiO.

TiO was known as a golden heterogeneous photocatalyst due to its chemical stability, low cost, nontoxicity, and strong oxidizing power. However, anatase TiO predominantly absorbs the photon energy in the ultraviolet region (λ < 387.5 nm); therefore, to increase the utilization of sunlight, the approach of doping of metals and nonmetals into pure TiO is implemented.

Recurrent vaginal vault dehiscence and evisceration following total laparoscopic hysterectomy, successfully repaired with polypropylene mesh and sacrocolpopexy.

Recurrent vault dehiscence is a rare and potentially serious complication following hysterectomy. We report a rare case of recurrent vault dehiscence and evisceration following a total laparoscopic hysterectomy (TLH) which was successfully repaired with polypropylene mesh and sacro-colpopexy. A 47-year-old multiparous woman underwent TLH for adenomyosis.

Different strategies of foam stabilization in the use of foam as a fracturing fluid.

An attractive alternative to mitigate the adverse effects of conventional water-based fluids on the efficiency of hydraulic fracturing is to inject foam-based fracking fluids into reservoirs. The efficiency of foaming fluids in subsurface applications largely depends on the stability and transportation of foam bubbles in harsh environments with high temperature, pressure and salinity, all of which inevitably lead to poor foam properties and thus limit fracturing efficiency. The aim of this paper is to elaborate popular strategies of foam stabilization under reservoir conditions.

Assessment of dynamic material properties of intact rocks using seismic wave attenuation: an experimental study.

The mechanical properties of any substance are essential facts to understand its behaviour and make the maximum use of the particular substance. Rocks are indeed an important substance, as they are of significant use in the energy industry, specifically for fossil fuels and geothermal energy. Attenuation of seismic waves is a non-destructive technique to investigate mechanical properties of reservoir rocks under different conditions.
