The researchers developed a method that removes color from water using a sponge-like material they created from wood pulp and small bits of metal. Cellulose, the main structure in plant cell walls and the most abundant natural material on Earth, provides the backbone of the material, which is decorated with tiny pieces of palladium. This metal serves as a catalyst to help remove color quickly.

At this point, once you’ve pretreated the stain, you can apply a stain remover (and, depending on the substance, even rub the mark with it). But you need to choose your cleanser wisely.

With humility, I was also a Nigerian in diaspora until I went back home in 1987 and later participated in Nation building under Babangida transition to civilian rule in 1990 of a two party system of SDP and NRC which was short lived and aborted unfortunately.

Considering the intensity of the MS peak of CuPc-MGT, the actual concentration of CuPc (fig. S9K) absorbed on MGT can be calculated

To understand the structure of the water wires under confinement, we collected the SFG spectra of the achiral HC8 and chiral S-HC8 I-quartets inserted in SLB together, as well as of the reference SLB without channels. We measured four different pure polarization combinations: the achiral combinations ppp and ssp (Fig. 3, A and B) and the chiral combinations psp and spp (Fig. 3, C and D). Measuring two different polarization combinations for the achiral and chiral combinations provides information on the alignment of the vibrations (perpendicular to or with a shallow angle with respect to the surface) depending on the symmetry of the functional group. We also measured mixed polarization combinations interfering achiral and chiral responses to further validate the observed chiral structures, as discussed in the Supplementary Materials.

The chiral SFG responses of the OH features in the bilayers with the HC8 and S-HC8 channels in both psp and spp are much stronger compared with the bilayer without channels. This observation proves that the water dipoles are not only aligned inside the channels but also that they form a chiral water superstructure templated by the I-quartet channel. Although the chiral psp response is stronger for S-HC8, as expected, the psp response of HC8 is significant and in spp the chiral SFG responses for both channels are similar. This finding is perhaps initially surprising. However, we know that each individual HC8 channel is chiral in the solid crystal structures and successive enantiomeric channels of opposite chirality are separated by water-free I-quartets. When HC8 is embedded in the bilayer membrane, the chiral polar region of lipids at the surface induces the amplification for one orientation that would preferentially form one chirality over another. In contrast, the noncentrosymmetric structures of chiral S-HC8 show a unique dipolar orientation for all water-filled channels, and correspondingly, the chiral response of the S-HC8 channels is larger compared with the achiral HC8 channel.

The highest profile bump was the firm’s loss of nearly $800 million in the firm, Altegrity, that was contracted to review federal contractors like Edward Snowden.

As part of her doctoral research, Dharmarwardana was investigating how the material, from a family of organic semiconducting materials called naphthalene diimides, changes color from orange to yellow as it is heated.

A new report launched by the Royal Society of New Zealand this afternoon says much more needs to be done to protect our precious biodiversity, with weeds, wasps, rats and sea squirts among a swarm of pests and diseases costing our economy and environment dearly.

Between 1945 and 1946, Abubakar Tafawa Balewa was awarded a scholarship to study abroad at a London University Institute of Education.   At the end of his sojourn, he received   a Teachers’ Certificate in History.   But like Macaulay, Azikiwe and Awolowo, Balewa, who had founded the Bauchi Discussion Circle, BDC, (an organisation interested in and committed to political reform) set the stage for his brand of political activism – the foundation for this laid while studying abroad.  Even Sir Ahmadu Bello, the Sardauna of Sokoto, upon return from abroad, was directly nominated to represent the province of Sokoto in the regional House of Assembly.   After attending Katsina College, Mallam Aminu Kano attended the University of London’s Institute of Education. He returned home to participate in politics, making the down-trodden his concern.

Jodie heard the cat screaming at around 7am on Saturday morning (July 28) and rushed towards the noise. She found Violet stuck in the contraption on a neighbouring roof – after the cat had dragged herself up some steps and onto the top of the building.

Salmon with a darker flesh can command an extra 50 cents to $1 per pound when offered side by side with lighter salmon, according to research by animal feed maker DSM.
