Jaja Nwachukwu was said to be among the influential voices that left a foot print on Nigeria’s journey to independence. Called to the Irish bar association – Kings Inn – in November 1944, after studying Law, with LL.B Prizeman in Roman Law, Constitutional and Criminal Law, he was a key participant in Nigeria’s constitutional conferences and struggle for independence from Great Britain.    When he returned to Nigeria in 1947,   he joined the NCNC, and was elected the Party’s Legal Adviser and Member of its National Executive Committee.

Today, he serves as the vice chairman and chief executive officer of the Clinton Health Access Initiative (CHAI). His son Seth is RI’s General Treasurer.

MGT nanocomposites were prepared through a layer-by-layer coating process (23). Magnetic Fe3O4 NPs were prepared through modified solvothermal reaction by reduction of FeCl3 (23). As shown in transmission electron microscopy (TEM) images (fig. S1A), the as-prepared Fe3O4 NPs were highly uniform with diameters of 120 ± 5 nm. We observed a well-resolved lattice fringe with an interplanar distance of 0.26 nm for Fe3O4, which corresponds to the (311) plane of magnetite (fig. S1B). In addition, hysteresis loops of Fe3O4 particles in fig. S1C indicate high-performance magnetic properties without remanence or coercivity at 300 K. We coated Fe3O4 NPs with GO through electrostatic adsorption with the linkage of polydimethyldiallylammonium chloride (PDDA) to produce magnetic Fe3O4@GO (MG). Scanning electron (SEM) micrographs (Fig. 2A) show that Fe3O4 NPs were effectively coated with GO. TEM images show that the irregular shapes of the nanocomposites were highly dispersed with diameters of 150 to 250 nm (Fig. 2B). Then, we prepared the uniform porous TiO2 shell via a versatile kinetics-controlled coating method to produce MGT nanocomposites. We observed the ternary heterostructure of MGT (size, 200 to 400 nm) coated by the aggregated TiO2 NPs (~8 nm) and with uniform pores (~5 nm; Fig. 2, C and D). N2 sorption isotherms (Fig. 2E) of the nanocomposites after calcination show typical type IV curves with distinct hysteresis loops close to the H1 type. The Brunauer-Emmett-Teller surface area and the pore volume of the as-prepared nanostructures were calculated to be as high as 105 m2 g−1 and 0.16 cm3 g−1, respectively. The corresponding pore size distribution curves (Fig. 2F) derived from the adsorption branches of the isotherms using the Barrett-Joyner-Halenda method show a sample pore size of ~4.3 nm, which was similar to that obtained from the SEM image. A high-resolution TEM (HR-TEM) image [Fig. 2G (III)] shows that the TiO2 NPs were crystallized with a well-resolved lattice fringe with an interplanar distance of 0.24 nm, which corresponds to the (103) plane of anatase (24). We carried out energy dispersive spectroscopy (EDS) to characterize the elemental composition and the structural relationship of the nanostructures from every step obtained (Fig. 2G). It was clear that Fe was located at the center of nanocomposites, while the shell contained C and Ti, which were well separated from each other. X-ray diffraction (XRD) fitted well to those of Fe3O4, GO, and TiO2 bulk phases (Fig. 2H). The diffraction peaks of Fe3O4 were ascribed to the (220), (311), and (440) planes. After Fe3O4 was coated with GO and TiO2, two additional diffraction peaks were observed at 21.2° and 43.3°, which should be ascribed to GO. Several new diffraction peaks appeared at 25.3°, 37.8°, 38.6°, 48.1°, 53.9°, and 55.1°, assigned to the (101), (004), (112), (200), (105), and (211) planes of anatase-phase TiO2, respectively (25, 26), confirming the successful preparation of MGT. We further used Raman and Fourier transform infrared (FTIR) spectroscopy to characterize the as-prepared MGT. As depicted in Fig. 2I, three distinct peaks at 397, 518, and 640 cm−1 in the Raman spectrum of MGT were observed, indicating the presence of anatase-phase TiO2 (26, 27). In the FTIR spectra of MGT (Fig. 2J), two additional infrared bands assigned to Ti–O–C at 1680 cm−1 and Ti–O–H stretching vibration at 3260 cm−1 were observed (28). Both Raman and FTIR results indicated that the MGT nanocomposites were successfully synthesized. The stepwise assembly of MGT was also monitored by microeletrophoresis measurements whose results were expressed as ζ-potentials (fig. S1D). Because of the superparamagnetic properties of the magnetic cores of MGT (Fig. 2K), the MGT nanocomposites were conveniently separated from the reaction solution after the photodegradation treatment upon application of an extended magnetic field. Moreover, it is known that TiO2 shows absorption ranging from 200 to 350 nm. On the other hand, absorbance of MGT nanocomposites extended to the visible region (400 to 600 nm) because of the conjugation of TiO2 with visible GO (fig. S1E) (26). Figure S2 shows the Raman spectra of copper phthalocyanine (CuPc) before and after illumination under visible light (460 nm < λ < 700 nm, 1000 W) on MGT nanocomposites. The intensity of the Raman spectra of CuPc sharply decreased after illumination by visible light for 90 min, revealing that CuPc was significantly photodegraded (26). In contrast, we obtained negligible changes for MT NPs (fig. S2, B and C). Accordingly, after five cycles of enrichment followed by illumination, the SERS activity of MGT remained more than 98% (fig. S2D), confirming the good recyclability of MGT. Considering the photocatalytic activity of MGT under the visible light region, we investigated the Raman signal reproducibility of MGT in fig. S3. After irradiating 15 times with an exposure time of 1 s, the Raman intensity of CuPc remained approximately 97%, indicating the high stability and reproducibility of MGT substrates. Besides, we measured the surface wettability of MGT through contact angle. As shown in fig. S1F, MGT showed hydrophilic properties with an MGT contact angle of 41° ± 2°, which is suitable for further bio-applications.

India imports more than 80 percent of its oil. Though the price of Brent crude oil — the global benchmark — has plummeted over the last two months, it has more than doubled since early 2016. Oil is priced in dollars. Its increase, combined with a 10 percent decline in the value of the rupee this year, have lifted the cost of petroleum-based products, from fuel to chemicals, used by key parts of Indian industry.

Back when rates were effectively zero, investors scoured the globe for higher returns, placing big bets on high-risk, high-reward countries — India among them — propping up the value of currencies. With the Federal Reserve now reversing course, money has been washing back to the United States, bolstering the American dollar, while depressing many emerging market currencies.

There would be a fee to go up, revenue from which could be applied to bridge maintenance. Given the dramatic vistas, I think that the deck would draw many happy people, albeit mostly in the warm weather.

Besides traditional rival Australia, other countries such as Argentina, Costa Rica, Nordic nations, Switzerland and Ireland offered great scenery but were closer to big population centres.

But then what do you use to cover them? There are so many options out there, it’s no wonder you might have color confusion. First, let’s start with the right type of dye. It’s a question of how much coverage you want and how long you want it to last. "The type of dye you use depends on the amount of gray you have," says Hazan. "If 40 percent or more of your head is gray, permanent color is the best option. If it’s 30 percent or less, you can use semi-permanent or vegetable dye."
