| 1 | A new scheme of implementing all-optical logic systems exploiting material nonlinearity and polarization based encoding technique显示文摘In this letter,the authors propose a new concept of implementing all-optical logic gates by representing the logic states with polarization of an optical signal .As the state of polarization of the light signal is very much suitable for encoding and detecting the bits of data of a digital signal in communication,the scheme may extend some wide applications in all-optical parallel computation and information processing. | Debajyoti Samanta Sourangshu Mukhopadhyay | 2008 | Optoelectronics Letters2008，4，3： | 3 |
| 2 | phytochemical investigation and in vitro antioxidant activity of an indigenous medicinal plant Alpinia nigra B.L.Burtt显示文摘Objective:To investigate antioxidant potential of methanol extract of Alpinia nigra leaves.Methods:The study was done by using various in vitro methods such as 1,1-diphenyl-2-picrylhydrazyl(DPPH),2,2-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid)(ABTS),nitric oxide and hydrogen peroxide radical scavenging assays.Phytochemical constituents,total phenolic content and total flavonoid content of the extract at different concentrations(10-500μg/mL)were determined.Results:Alpinia nigra leaves showed high free radical scavenging activity as evidenced by the low IG_(50)values in DPPH(64.51μg/mL),in ABTS(28.32μg/mL),in nitric oxide(80.02μg/mL)and in H_2O_2(77.45μg/mL)scavenging assays.Furthermore the TPC and TFC of the extract were found to be 69.25 mg gallic acid equivalent per gram of extract and 78.84 mg quercetin equivalent per gram of extract respectively.Conclusions:The results of present comprehensive analysis demonstrated that Alpinia nigra leaves possess high phenolic,flavonoid contents and potential antioxidant activity,and could be used as a viable source of natural antioxidants and might be exploited for functional foods and neutraceutical applications. | Suprava Sahoo Goutam Ghosh Debajyoti Das Sanghamitra Nayak | 2013 | Asian Pacific Journal of Tropical Biomedicine2013，3，11： | 2 |
| 3 | Photocatalytic reduction of organic pollutant under visible light by green route synthesized gold nanoparticles显示文摘We report a rapid method of green chemistry approach for synthesis of gold nanoparticles(AuNPs)using Lagerstroemia speciosa leaf extract(LSE). L. speciosa plant extract is known for its effective treatment of diabetes and kidney related problems. The green synthesis of Au NPs was complete within 30 min at 25°C. The same could also be achieved within 2 min at a higher reaction temperature(80°C). Both UV–visible spectroscopy and transmission electron microscopy results suggest that the morphology and size distribution of Au NPs are dependent on the pH of gold solution,gold concentration,volume of LSE,and reaction time and temperature. Comparison between Fourier transform infrared spectroscopy(FT-IR)spectra of LSE and the synthesized Au NPs indicate an active role of polyphenolic functional groups(from gallotannins,lagerstroemin,and corosolic acid)in the green synthesis and capping of Au NPs. The green route synthesized Au NPs show strong photocatalytic activity in the reduction of dyes viz.,methylene blue,methyl orange,bromophenol blue and bromocresol green,and 4-nitrophenol under visible light in the presence of Na BH_4. The non-toxic and cost effective LSE mediated Au NPs synthesis proposed in this study is extremely rapid compared to the other reported methods that require hours to days for complete synthesis of Au NPs using various plant extracts. Strong and stable photocatalytic behavior makes Au NPs attractive in environmental applications,particularly in the reduction of organic pollutants in wastewater. | Bharat C.Choudhary Debajyoti Paul Tarun Gupta Sandesh R.Tetgure Vaman J.Garole Amulrao U.Borse Dipak J.Garole | 2017 | Journal of Environmental Sciences2017，29，5： | 2 |

| 18 | Spontaneous rupture of the renal pelvis presenting as an urinoma in locally advanced rectal cancer显示文摘A 29-year-old gentleman underwent a transverse colostomy for intestinal obstruction caused by advanced rectal carcinoma. On the 5th postoperative day, the patient developed a painful swelling on the right side of the abdomen. The contrast enhanced computed tomography of the abdomen revealed a right sided hydronephrosis, a large rent in the renal pelvis, and a large retroperitoneal fluid collection on the right side. Percutaneous nephrostomy and pigtail catheter drainage of the urinoma led to resolution of abdominal swelling. Development of a urinoma as a consequence of rectal carcinoma is highly unusual. Prompt imaging for confirmation of diagnosis, decompression of the renal pelvicalyceal system, and drainage of the urinoma limits morbidity. | Pankaj Kumar Garg Debajyoti Mohanty Vinita Rathi Bhupendra Kumar Jain | 2014 | World Journal of Clinical Cases2014，2，4： | 1 |
