在机理验证中，对比原始活性炭和吸附阿特拉津饱和的活性炭在臭氧处理下的性质变化，通过FTIR、Boehm滴定以及Raman、XPS等手段，观察活性炭在臭氧处理或再生4 h过程中官能团和石墨结构的变化，发现原始的活性炭随着臭氧处理含氧官能团不断减少，而吸附饱和的活性炭含氧官能团减少的程度减弱，说明该工艺可以有效保护活性炭表面...
Coverages of θ1 result in two additional bands in the spectrum at 2430 cm 1 and 2340 cm 1 indicating the formation of 3D ice. High coverages at T130 K lead to the formation of 3D Ice I whereas at T=81 K amorphous ice is formed. The complete loss of absorption upon heating the ...
The FTIR spectrum revealed the presence of asymmetric and symmetric vibrations of the aromatic ring and was assigned to C = C or C = O. Fungi showed biosorption ability across broad functional groups. These results provide interesting information about the ability of Pichia kluyveri FM012...
are likely to be the main reservoirs of solar wind-derived water23. Our investigation of solar wind-derived water in lunar minerals based on analyzing pyroxene, plagioclase, and olivine grains selected from CE5 lunar samples using Fourier transform infrared spectroscopy (FTIR), nanoscale secondary io...
(FTIR) spectra in Fig.2btestify to the appearance of symmetric stretching vibration and asymmetric vibration of (Si–O–Si) at about 800 and 1085 cm−1in the spectrum of the wr-PNDs27, while they are absent in the spectrum of the pristine PQDs (Supplementary Fig.5a). The peak at...

Coverages of θ⩾1 result in two additional bands in the spectrum at 2430 cm−1 and 2340 cm−1 indicating the formation of 3D ice. High coverages at T⩾130 K lead to the formation of 3D Ice I whereas at T=81 K amorphous ice is formed. The complete loss of absorption upon ...
The spectrum of the symmetric top, hydrogen-bonded heterodimer H3NHCN has been recorded between 2900 and 3200cm1 using a high resolution FTIR spectrometer. The more intense bands are associated with the 2 (HCN stretch) vibration and incl... IWM Smith,G Yarwood - 《Molecular Physics》 被引量...
water droplets spread rapidly along the stripes on the surface and end up with a contact angle of 0° that is significantly lower than 10° of rGO/alginate hydrogel membrane without the fish-scale-like pattern39. Meanwhile, an absorbance of 95% within the full spectrum of sunlight is achieved...
(PMMA) at the same humidity excludes water adsorption on the top surface of the MoS2film. Meanwhile the sapphire surface exposed after the MoS2film is peeled off also shows an apparent water signal in the ATR-FTIR spectrum. These results verify the existence of a water layer at the MoS2-...
