Corrosion Behavior of Aluminium-Coated Cans.

Hundreds of billions of aluminium-based cans are manufactured and used every year worldwide including those containing soft drinks. This study investigates and evaluates the performance and quality of two well-known energy and soft drinks brands, Green Cola and Red Bull. Recent health hazards and concerns have been associated with aluminium leakage and bisphenol A (BPA) dissociation from the can's internal protective coating.

Double Double to Double Perovskite Transformations in Quaternary Manganese Oxides.

Control of cation ordering in ABX perovskites is important to structural, physical and chemical properties. Here we show that thermal transformations of AA'BB'O double double perovskites, where both A and B sites have 1:1 cation order, to (A A' ) BB'O double perovskites with fully disordered A/A' cations can be achieved under pressure in CaMnMnWO and SmMnMnTaO , enabling both polymorphs of each material to be recovered. This leads to a dramatic switch of magnetic properties from ferrimagnetic order in double double perovskite CaMnMnWO to spin glass behaviour in the highly frustrated double perovskite polymorph.

Unconventional magnetism in the high pressure 'all transition metal' double perovskite MnNiReO.

MnNiReO, prepared at high pressure and temperature, has a highly-distorted double perovskite structure. Canted antiferromagnetic order is observed below T = 80 K and an unusual continuous spin rotation of Mn spins occurs down to T = 42 K where a collapse in weak ferromagnetism evidences an unprecedented switching of the weak ferromagnetic moment directions.

Improvement in Electrode Performance of Novel SWCNT Loaded Three-Dimensional Porous RVC Composite Electrodes by Electrochemical Deposition Method.

The three-dimensional (3D) composite electrodes were prepared by depositing different amounts of acid-functionalized single-walled carbon nanotubes (a-SWCNTs) on porous reticulated vitreous carbon (RVC) through the electrochemical deposition method. The SWCNT was functionalized by the reflux method in nitric acid and was proven by Raman and visible spectra. The optimum time for sonication to disperse the functionalized SWCNT (a-SWCNT) in dimethyl formamide (DMF) well was determined by UV spectra.

Radiological Findings in Persistent Müllerian Duct Syndrome: Case Report and Review of Literature.

This case involved a 36-year-old adult male who presented with an unusual inguinal hernia in which the uterus and fallopian tubes were identified as contents of the inguinal hernia sac. These findings reflected a rare autosomal recessive developmental syndrome known as PMDS (persistent Müllerian duct syndrome). The diagnosis was established and confirmed via radiological-mainly MRI-investigation.
