the hydrogel sponges have prepared successfully from gelatin/ch.tosan(GEL/CtS) matrix with different polyols basing on scanning electron microscopy(SEM) and Fourier-transform infrared spectroscopy(FtIR) analysis. the results indicate th.t the compressibility and thermal properties(thermal gravimetric analysis, tGA) were improved significantly with adding the different polyols [poly(vinyl alcohol)-PVA, and poly(ethylene glycol)-poly(propylene glycol)-poly(ethylene glycol) – PEPEG] into GEL/CtS matrix. Specially, the as-prepared hydrogel sponges with superabsorbent behavior were also investigated with.the attained water absorption capacity to 605 g gand 585 g gfor GCV＿1/1/0.3 and GCE＿1/1/0.3 sponges, respectively, as well as the excellent water absorption capacity in a wide range of p h and salt concentration. hence, these studies demonstrated th.t the hydrogel sponges are concerned as potential and promising candidates to apply especially in the fields of biomedicine and hygiene.

Gas-phase mechanism and kinetics of the reactions of the 2-propargyl radical(h2CCCh), an important intermediate in combustion processes, with formaldehyde were investigated using ab initio molecular orbital theory at the coupled-cluster CCSD(t)//B3LYP/6-311++G(3df,2p) method in conjunction with.transition state theory(tSt), variational transition state theory(VtSt) and Rice-Ramsperger-Kassel-Marcus(RRKM) calculations for rate constants. the potential energy surface(PES) constructed shows th.t the h2CCCh+hChO reaction has six main entrances, including two h-abstraction and four additional channels, in which.the former is energetically more favorable. the h-abstraction channels slide down to two quite weak pre-complexes COM-01(-9.3 kJ/mol) and COM-02(-kJ/mol) before going via energy barriers of 71.3(t0/P1) and 63.9 kJ/mol(t0/P2), respectively. two post-complexes, COM-1(-17.8 kJ/mol) and COM-2(-23.4 kJ/mol) created just after coming out from t0/P1 and t0/P2, respectively, can easily be decomposed via barrier-less processes yielding h2CCCh2+ChO(P1,-12.4 kJ/mol) and hCCCh3+ChO(P2,-16.5 kJ/mol), respectively. the additional channels occur initially by formation of four intermediate states, h2CCChCh2O(I1, 1.1 kJ/mol), hCCCh2Ch2O(I3, 4.5 kJ/mol), h2CCChOCh2(I4, 10.2 kJ/mol), and hCCCh2OCh2(I6, 19.1 kJ/mol) via energy barriers of 66.3, 59.2, 112.2, and 98.6 kJ/mol at t0/1, t0/3, tOM, and tO/6, respectively. Of which.two channels producing 14 and 16 can be ignored due to coming over tlie high barriers tOM and tO/6, respectively. the rate constants and product branching ratios for the low-energy channels calculated show th.t the h2CCCh+hChO reaction is almost pressure-independent. Altliough.the h2CCCh+hChO→Ⅰ1 and h2CCCh+hChO→Ⅰ3 channels become dominant at low temperature, however, they are less competitive channels at high.temperature.
