Many anuran species exhibit striking color and/or pattern polymorphisms. We sampled 599 adult rice frogs, Fejervarya multistriata, from a rice paddy in the periphery of the Lingnan Nature Reserve （Huangshan, Anhui）. We recognized ten morphs based on three relatively stable and distinct morphological characters： dorsal ground color （green or gray）, middorsal stripe （absence, wide, or narrow）, occipital rusty spot （absence or presence）. The grey individuals are more common and larger than the green individuals （frequency 88.1 vs. 11.9%, respectively） and （SVL 39.4-36.6 vs. 35.7-34.6 mm, respectively）. There is a higher proportion of individuals with a middorsal stripe （59.7%） while absence of the occipital rusty spot is more common in the population （82.3%）. We expect additional studies in different habitat types would help build our understanding of the relationship between color polymorphism and habitat, geography, and climate.

Laser cladding experiments were done on a 5-kW continuous wave CO2 laser to synthesize TiC and TiB rein- fowed titanium matrix composite coatings on Ti-6AI-4V alloy with a mixture of Ti and B4C precursor powder. The ther- modynamics of the reactions were calculated and analyzed. The microstructure and phase evolution of TiB and TiC com- posites were investigated. The results showed that the chemical reaction between Ti and B4C would release much heat, and these compounds, TiC, TiB, and small amount of TiB2, can be formed on the surface of Ti-6AI-4V alloy if the supplied en- ergy is sufficient to excite the reaction among the initial products. A good metallurgical bond between the coating and the substrate can be achieved. The microhardness of coating was irregular and the maximum value was approximately HV600.

Pure organic luminogens with room temperature phosphorescence(RTP) have drawn much attention due to their fundamental importance and promising applications in optoelectronic devices, bioimaging, sensing, etc. Fluorescence-phosphorescence dual emission at room temperature, however, is rarely observed in pure organic materials. Herein, we reported a metal-and heavy-atom free pure organic luminogen with tert-butyl groups, DtBuCZBP, which is ready to form organogels in dimethylsulfoxide(DMSO).It emits prompt and delayed fluorescence, as well as RTP, namely dual emission in as-prepared solid, gels and polymeric *** the best of our knowledge, it is the first example of metal-and heavy-atom free pure organic gelator with RTP emission. Such unique RTP and moreover dual emission properties in different states make DtBuCZBP a potential material for diverse applications.
