The capability of an airborne 2-μm integrated path differential absorption (IPDA) lidar for high-accuracy and high-precision active remote sensing weighted-average column dry-air volume mixing ratio atmospheric carbon dioxide (XCO2) is demonstrated. A test flight was conducted over the costal oceanic region USA to assess instrument performance during severe weather. IPDA targets CO2 R30 line us...

The utilisation of reclaimed asphalt pavement (RAP) as a suitable substitute for natural aggregate and binder offers an energy-saving cost-effective approach to enhance the performance mix. Realising potential use RAP promising recycling technique, many countries are seeking recycle part global effort address rising challenge climate change contribute sustainable environment. This study aimed d...

We study a sub monolayer He-4 adsorbed on fluorographene (GF) and hexagonal boron nitride (hBN) at low coverage. The adsorption potentials have been computed ab-initio with suitable density functional theory including dispersion forces. properties of the atoms finite temperature path integral Monte Carlo T=0 K variational integral. From both methods we find that lowest energy state GF is superf...

Abstract CaCO 3 -pulp composite was prepared via precipitation of calcium hydroxide in the presence pulp. In order to investigate selectivity and mechanism, substrate pulps obtained composites were fractionated (R30, R100, R200, R400 a sedimented fraction that passed 400 mesh wire) using Bauer-McNett unit. The main fractionation criterion therefore fiber length. pulp used CTMP (chemithermomecha...

The (0001) surface of a-Mo2C prepared by Ar ion bombardment and annealing was characterized using X-ray photoelectron spectroscopy and low energy electron diffraction (LEED). An ion-bombarded surface annealed to 1000 K exhibits an Mo/C ratio of 2.2, characteristic of an Mo-terminated surface. The Mo-terminated surface exhibits a complex, but predominantly ‘(1×1)’ hexagonal LEED pattern on a dif...
