Summary: Coal pyrolysis gas, containing nitrogen-containing species (HCN and NH3), is a promising reburn fuel with excellent NO reduction performance. In this study, the effects of oxygen and nitrogen-containing species on NO removal performance with HCN and NH3 were investigated using reactive force field molecular dynamics simulations. The results show that reducing O2 concentrations and increasing the amount of nitrogen-containing species can improve the NO reduction performance by coal pyrolysis gas. The study also elucidates the effects of oxygen and nitrogen-containing species on the NO removal and the mechanisms of NO consumption and N2 formation. Practical operating strategies are proposed based on the simulation results to optimize the NO reduction efficiency.

Summary: The detailed kinetic mechanisms for the reactions of hydrogen cyanide (HCN) and hydrogen isocyanide (HNC) with the methyl radical (CH3) were investigated at the CCSD(T)/cc-pVQZ//M06-2X/6-311++G(2df,2p) level of theory. Temperature and pressure-dependent rate constants were determined using variational transition state theory (VTST) and Master Equation/Rice-Ramsperger-Kassell-Marcus (ME/RRKM) method. The reaction mechanisms were found to depend on temperature and pressure, with the C-addition channel dominant for HCN reaction and the C-addition channel dominant for HNC reaction.

Summary: Contrary to common belief, the generation of free carriers can have a positive impact on Cherenkov-type terahertz emission from ultrashort laser pulses by broadening the radiation bandwidth. This is achieved through the acceleration of optically generated carriers by rectified electric fields, resulting in a surge current and broadened emission. Specific results are provided for GaP pumped at a 1.7-μm wavelength.

Summary: Future wireless communications require higher security and data rates. We propose an XOR encryption/decryption technique based on the AND operation between two encrypted data sequences on different terahertz carriers. By employing XOR as the decryption method, the system becomes more secure and increases the computational complexity for eavesdroppers. We successfully demonstrated the XOR operation between two data sequences on FSK-modulated terahertz waves using XOR encryption transmitters/receivers consisting of high-speed wavelength tunable lasers and arrayed uni-traveling-carrier photodiodes (UTC-PDs).

Summary: A novel ultra-wideband terahertz circulator is implemented by inserting a NixZn1-xFe2O4 ferrite sphere into the Al2O3 dielectric rod-array. The operating bandwidth of the circulator is broadened to 40 GHz via the external matching method through two hexagonal aluminum sheets. The three-dimensional numerical simulation suggests that the designed circulator also has an excellent insertion loss and isolation of 49.37 dB and 0.56 dB, respectively, via the finite element method.

Summary: With the new generation of observatories, the process of characterizing exoplanet atmospheres will require reinvention. Current limitations lie mostly in the instruments, but soon the models used to translate spectra into atmospheric properties will become bottlenecks. Our study shows that the opacity models used to decode exoplanet spectra have limitations that result in an accuracy wall in atmospheric properties, which is higher than the precision targeted by current space telescope programs. We propose a two-tier approach to alleviate this problem.

Summary: The development of cavity based infrared spectroscopy techniques, particularly cavity ring-down spectroscopy, has been successful for sensitive measurements. However, the construction difficulty of high finesse cavities has limited its application for THz frequencies. By using a corrugated waveguide and photonic mirrors, we have achieved finesse values of 3500. This has allowed us to measure the absorption of various gases and samples, demonstrating good agreement with a certified gas analyser for industrial samples.

It was found that the hygroscopic growth of sand/dust particles has a significant effect on optical attenuation when the relative humidity is above 60%. Based on the double-parameter Kasten model, a proposed optical attenuation model takes into account visibility, particle size, relative humidity, and optical wavelength. Numerical calculations considering the hygroscopicity effect were also performed, and the results were in agreement with the experimental data.

Summary: In this study, we analyze TPX cells operating in the self-sustaining circuit and examine the effects of different bandgaps on their performance. The results show that the bandgap energy of the LED must exceed that of the PV cell for the TPX cell to function in a self-sustaining parallel circuit. Additionally, a narrower bandgap energy for the PV cell and a wider bandgap energy for the LED can improve the performance of the TPX cell in the self-sustaining circuit.
