Microwave drying is an advanced drying technique，in which thermal energy is generated inside the material by electromagnetic energy radiation and hence moisture is intensively evaporated toward the material surface. But heating non-uniformity is an inherent problem to microwave drying. In this paper，the factors relating to microwave heating non-uniformity were analyzed，and then feasible approaches to microwave heating uniformity were outlined by improving the uniformity of electromagnetic field distribution and moving the materials to be processed. At last，R & D trends of microwave drying with heating uniformity were pointed out and discussed.

In the end，key urgent problems are addressed and perspectives are discussed.

Electrospun hierarchical porous materials with micro- and nanometer scale porous structure offer high specific surface area and unique properties for various applications. The preparation of electrospun hierarchical porous nanofiber mats is reviewed，including organic series and ceramic series. For the organic series，phase separation induced by solvent evaporation and other factors is the main mechanism of forming porous structure. While the template methods are often used to prepare inorganic porous nanofibers. The hierarchical pore structure further enlarges the surface area and enhances the hydrophobic property of the fiber mat，which alters the performance of the mat greatly.

The rigid polyurethane foam blown by water was prepared with a polyisocyanate polyaddition (PIPA) polyol synthesized in lab and a polyol with a low hydroxyl value. The effects of such factors as the ratio of two polyols，chain extender and cross linker，isocyanate index on polyurethane product mechanical properties like compression，bend，impact strengths and dynamic rheological properties were studied. When the ratios of 1，4-butanediol，trimethylolpropane and TMN-3050 were 1.0pphp，1.0pphp，15pphp respectively，and the isocyanate index was 1.15，the product performed best with good strength and toughness.

Chitosan/gelatin hydrogels were prepared through the reaction between natural chitosan and gelatin. Swelling ratios of the hydrogels in buffer solutions at different pH values were studied. The structure was confirmed by FTIR and SEM. The results showed that the hydrogels were strongly pH-sensitive and the swelling ratio of the hydrogels in acid medium was higher than that in alkaline medium. Furthermore，the largest swelling ratio was obtained in a pH 3.0 buffer solution and the smallest was obtained in a pH 9.0 buffer solution. The hydrogels had good swelling-contracting reversibility in the solution which pH value was alternately changed. With the increase of glutaraldehyde dosage，the SR of the hydrogels decreased in buffer solutions at different pH values.

The precipitation polymerization method was optimized by using a L9(34) orthogonal factorial design for the preparation of homoharringtonine imprinted polymer (HIP). Optimization of the synthesis condition for the HIP was performed by investigating the influence of four factors, i.e. solvent ( acetonitrile) dosage (A), reaction temperature (B), functional monomer (methacrylic acid, MAA) dosage (C) and crosslinker (ethylene glycol dimethyl acrylate, EGDMA) dosage (D), and the interaction of such factors on the adsorption capacity of HIP obtained under different conditions to the template molecule. The results indicated that the influence of these factors on the adsorption capacity of the HIP decreased in the order of C, D, A and B and the optimized synthesis condition was as follows：0.12 mmol MAA, 0.4 mmol EGDMA, 2.5 mL acetonitrile, reaction temperature at 65 ℃ under the fixed template dosage (0.01 mmol). Also, the interaction of such factors could influence the adsorption capacity of HIP to the template.

Positively charged Bacillus subtilis neutral proteinase dissolved in the aqueous phase at a pH value below its pI could form hydrophobic ion-pair with the anionic surfactant AOT in isooctane when they are mixed together due to electrostatic attraction. Thus，the hydrophilic enzyme could be “solubilized” into the hydrophobic isooctane. In this paper，the factors affecting the ion pair formation were investigated，such as，mixing conditions of the two phases，initial pH value and ionic strength，salts，the concentrations of the enzyme and surfactant AOT. The results indicated that magnetic stirring at 120r/min for 6 h was better than other mixing methods. The initial pH value of the aqueous phase affected both formation of enzyme-surfactant ion pair and transfer of the enzyme into isooctane. The optimal pH value was about 5.0. Addition of CaCl2 could partially prevent emulsifying during mixing，but excessive CaCl2 could negatively affect formation of ion pair and transfer of the enzyme from aqueous phase into isooctane. The transferred amount of enzyme into isooctane increased when AOT concentration increased within the limit (below the critical concentration of reverse micelle formation，4.9 mmol/L)，although the initial concentration of the enzyme in the aqueous phase was kept constant. However，with a constant AOT in isooctane，the enzyme transfer increased with increasing initial concentration of the enzyme in the aqueous phase first but decreased with further increase. The results showed that Bacillus subtilis neutral proteinase extracted into the organic phase was still active and could catalyze the transesterification.

：As a fuel oxidizing agent，methyl tert-butyl ether (MTBE) is added to gasoline in replacement of tetraethyl lead to enhance octane number. The addition of MTBE also improves the combustion efficiency and therefore decreases the emission of pollutants like CO and O3. On the other hand，because of gasoline spills，mainly due to leaking underground storage tanks，MTBE has become a prevalent contaminant in groundwater. The reason for such widespread contamination is that MTBE is highly soluble in water and recalcitrant to biodegradation. The chemical characteristics of MTBE make it a challenge to treatment in the natural environment. Biological treatment of soil and groundwater is expected to be a cost-effective technique. It was reported that MTBE was able to degrade through co-oxidation or could be used as a carbon and energy source by many microorganisms. In China，the studies on MTBE removal by bioremediation techniques are still at their infancy for both fundamental research and on-site application. Based on previous studies，the reported microorganisms able to degrade MTBE were summarized，and then emphasis was put on the key catabolic enzymes involved in MTBE degradation.

Chitosan beads were prepared by the dripping granulation method，using chitosan (CS) as the raw material，sodium tripolyphosphate (TPP) and epichlorohydrin (ECH) as the cross-linking reagent. The adsorption properties of the chitosan beads for two kinds of acidic dyes，acid bordeaux B(ABB) and nylosan yellow N-3RL(NYN) from water was investigated. Under the initial concentration of dye waste water 100 mg / L and volume 50 mL，the optimum adsorption conditions of chitosan beads for the two dye waste waters were obtained as follows：particle size of chitosan beads 0.5mm，dosage 20.0mg，contact time 16 h，pH value 3， temperature 20℃ for ABB，30—50℃ for NYN，oscillating rate 150r/min. Under the optimum adsorption conditions，the adsorption process of ABB and NYN fitted well with both Freundlich model and Langmuir model，and the maximum adsorption capacity for ABB and NYN were 714.29 mg/g and 769.23 mg/g respectively，which exceeded the maximum adsorption capacity by non-bead chitosan 443.99 mg/g，102.53 mg/g respectively. The saturated chitosan beads were desorbed by 0.01mol/L NaOH，the regeneration rate were 99.08%，99.35% for each dye，and the beads could be used repeatedly which would reduce the decoloration cost.
