Hcl Medium

In HCl medium and in the presence of CuSO4, Na3AsO4 can be reduced by NaH2PO2 to form As nanoparticles (AsNs) which exhibited a strong resonance Rayleigh scattering (RRS) peak at 370 nm. Under the chosen conditions, the increased intensity at 370 nm was linear to As5+ concentration in the range of 0.48-38.0×10-6 mol/L, with a regression equation of ΔI370nm = 82.3 CAs + 33.9, a correlation coefficient of 0.9878 and a detection limit of 2.0×10-7 mol/L As5+. The proposed method was applied to detect As5+ concentration in waste water, with simplicity, rapidity and accuracy. Thus, a novel RRS spectral method was established to determine As5+.

Nanogold Catalysis

Hemin aptamer was used to modify gold nanoparticles (AuNPs) to obtain a stable aptamer-nanogold probe (AussDNA). In the condition of pH 8.0 Tris-HCl buffer solution containing 50mmol/L NaCl, the substrate chain of AussDNA was cracked by hemin to produce a short single-stranded DNA(ssDNA) and then further combined with hemin to form a stable hemin-ssDNA conjugate. The AuNPs released from AussDNA would be aggregated in the condition of 50mmol/L NaCl and exhibited a strong resonance Rayleigh scattering (RRS) peak at 368nm. Under the selected conditions, the increased RRS intensity (ΔI368nm) was linear to hemin concentration in the range of 5-750nmol/L, with a detection limit of 66 pmol/L. This RRS method was applied to determination of residual hemin in serum samples, with satisfactory results. The remnant AussDNA in the solution exhibited a strong catalytic activity on the gold particle reaction of HAuCl4-vitamine C (VC) that can be monitored by RRS technique at 368 nm. When the hemin concentration increased, the AussDNA decreased, the catalysis decreased, and the RRS intensity at 368nm decreased. The decreased RRS intensity ΔI368nmwas linear to the hemin concentration in the range of 1-200nmol/L, with a detection limit of 54 pmol/L. Accordingly, a sensitivity, selectivity, and simplicity new method of resonance Rayleigh scattering spectra to detect hemin using aptamer-modified nanogold as catalyst was established.

Climate Crisis

In 2014 Greenpeace posted a short video appealing to Lego to end its cooperation with Royal Dutch Shell. The video raised an informal accusation and invited its audiences to support it, which more than one million people did. A reputational crisis was inflicted upon the two companies. The article discusses the rhetoric that enabled this activist success and asks to what extent the example set by Greenpeace might be worthy of imitation. It is argued that the mobilizing effect of the video cannot be explained merely by studying its spectacular form and content. The unusual effect must be seen in light of the climate crisis as an affective context that gave the emotional appeals of the video a strong resonance. It was the current climate crisis, implied in the video, which helped create a burning platform for change in the conduct of Lego and Shell

Nonlinear Energy

The nonlinear energy sink (NES) is usually coupled with a linear oscillator (LO) to rapidly transfer and immediately dissipate a significant portion of the initial shock energy induced into the LO. This passive energy transfer and dissipation are usually achieved through strong resonance captures between the NES and the LO responses. Here, a nontraditional set of nonlinear coupling restoring forces is numerically investigated to introduce enhanced versions of the NESs. In this new set of nonlinear coupling restoring forces, one has a varying nonlinear stiffness that includes both of hardening and softening stiffness components during the oscillation, which appear in closed-loops under the effect of the damping. The obtained results by the numerical simulation have shown that employing this kind of the nonlinear restoring forces for passive targeted energy transfer (TET) is promising for shock mitigation.

AbstractAb initioelectronics structure calculations have been carried out in a series of RPb2n-1Te2n, n=16, compounds to understand the nature of “defect” states introduced by R where R = vacancy, monovalent Na, K, Rb, Cs, Ag atoms and divalent Cd atoms. We find that the density of states (DOS) near the top of the valence band and the bottom of the conduction band get significantly modified. The Na atom seems to perturb this region least (ideal acceptor in PbTe) and the other monovalent atoms enhance the DOS near the top of the valence band. Cd is an interesting case, since it introduces a strong resonance state near the bottom of the conduction band.

Ion Laser

A krypton ion laser operating at 6470 Å excites strong resonance fluorescence in nitrogen dioxide gas. The fluorescence bands have "parallel" structure (ΔK = 0) and are assigned to the electronically allowed subsystem of a 2B2–2A1 electronic transition. A partial rotational analysis is given for the upper state of the fluorescence bands, and their relationship to the absorption spectrum in the region 6000–11 500 Å is discussed.
