| 1 | MHD graphene-polydimethylsiloxane Maxwell nanofluid flow in a squeezing channel with thermal radiation effects显示文摘The magnetohydrodynamic (MHD) graphene-polydimethylsiloxane (PDMS) nanofluid flow between two squeezing parallel plates in the presence of thermal radiation effects is investigated. The energy efficiency of the system via the Bejan number is studied extensively. The governing partial differential equations are converted by using the similarity transformations into a set of coupled ordinary differential equations. The set of these converted equations is solved by using the differential transform method (DTM). The entropy generation in terms of the Bejan number, the coefficient of skin-friction, and the heat transfer rate is furthermore investigated under the effects of various physical parameters of interest. The present study shows that the Bejan number, the velocity and thermal profiles, and the rate of heat transfer decrease with a rise in the Deborah number De while the skin-friction coefficient increases. It is also observed that the entropy generation due to frictional forces is higher than that due to thermal effects. Thus, the study bears the potential application in powder technology as well as in biomedical engineering. | G.C.SHIT S.MUKHERJEE | 2019 | Applied Mathematics and Mechanics(English Edition)2019，40，9： | 2 |

| 5 | Influence of breakup on elastic and α-production channels in the ^6Li+^116Sn reaction显示文摘The effects of breakup reactions on elastic and α-production channels for the ~6Li+^(116)Sn system have been investigated at energies below and near the Coulomb barrier. The angular distributions of α-particle production differential cross sections have been obtained at several projectile energies between 22 and 40 MeV. The measured breakup α-particle differential cross sections and elastic scattering angular distributions have been compared with the predictions of continuum-discretized coupled channels(CDCC) calculations. The influence of breakup coupling has also been investigated by extracting dynamic polarization potentials(DPP) from the CDCC calculations. From the predictions of CDCC calculations the relative importance of the nuclear, Coulomb, and total breakup contributions have also been investigated. The nuclear breakup couplings are observed to play an important role in comparison to the Coulomb breakup for the direct breakup mechanisms associated in the reaction of ~6Li projectile with ^(116)Sn target nuclei. The influence of strong nuclear breakup coupling exhibits suppression in the Coulomb-nuclear interference peak. The direct breakup cross sections from the CDCC calculations under-predict the measured α-particle differential cross sections at all energies. This suggests that the measured α particles may also have contributions from other possible breakup reaction channels. | D.Patel S.Mukherjee N.Deshmukh J.Lubian 王建松 T.Correa B.K.Nayak 杨彦云 马维虎 D.C.Biswas Y.K.Gupta S.Santra E.T.Mirgule L.S.Danu N.L.Singh A.Saxena | 2017 | Chinese Physics C2017，41，10： | 0 |
| 6 | Fractal geometrical properties of nuclei显示文摘We present a new idea to understand the structure of nuclei and compare it to the liquid drop model. After discussing the probability that the nuclear system may be a fractal object with the characteristic of self-similarity,the irregular nuclear structure properties and the self-similarity characteristic are considered to be an intrinsic aspect of the nuclear structure properties. For the description of nuclear geometric properties, the nuclear fractal dimension is an irreplaceable variable similar to the nuclear radius. In order to determine these two variables, a new nuclear potential energy formula which is related to the fractal dimension is put forward and the phenomenological semiempirical Bethe–Weizsa¨cker binding energy formula is modified using the fractal geometric theory. One important equation set with two equations is obtained, which is related to the concept that the fractal dimension should be a dynamic parameter in the process of nuclear synthesis. The fractal dimensions of the light nuclei are calculated and their physical meanings are discussed. We compare the nuclear fractal mean density radii with the radii calculated by the liquid drop model for the light stable and unstable nuclei using rational nuclear fractal structure types. In the present model of fractal nuclear structure there is an obvious additional feature compared to the liquid drop model, since the present model can reflect the geometric information of the nuclear structure, especially for nuclei with clusters, such as the α-cluster nuclei and halo nuclei. | 马维虎 王建松 王琦 S.Mukherjee 杨磊 杨彦云 黄美容 | 2015 | Chinese Physics C2015，39，10： | 0 |
| 7 | Investigation of 58Ni(n, p)58Co reaction cross-section with covariance analysis显示文摘The excitation function of the 58Ni(n,p)58Co reaction was measured using the well-established neutron activation technique andγ-ray spectroscopy.Neutrons in the energy range of 1.7 to 2.7 MeV were generated using the 7Li(p,n)reaction.The neutron flux was measured using the standard 115In(n,n’)115mIn monitor reaction.The results of the neutron spectrum averaged cross-section of 58Ni(n,p)58Co reactions were compared with existing cross-section data available in the EXFOR data library as well as with various evaluated data libraries such as ENDF/B-VIII.0,JEFF-3.3,JENDL-4.0,and CENDL-3.2.Theoretical calculations were performed using the nuclear reaction code TALYS.Various nuclear level density(NLD)models were tested,and their results were compared with the present findings.Realistic NLDs were also obtained through the spectral distribution method(SDM).The cross-section results,along with the absolute errors,were obtained by investigating the uncertainty propagation and using the covariance technique.Corrections forγ-ray true coincidence summing,low-energy background neutrons,andγ-ray self attenuation were performed.The experimental cross-section obtained in the present study is consistent with previously published experimental data,evaluated libraries,and theoretical calculations carried out using the TALYS code. | Akash Hingu S.Mukherjee Siddharth Parashari Arora Sangeeta A.Gandhi Mahima Upadhyay Mahesh Choudhary Sumit Bamal Namrata Singh G.Mishra Sukanya De Saurav Sood Sajin Prasad G.Saxena Ajay Kumar R.G.Thomas B.K.Agrawal K.Katovsky A.Kumar | 2024 | Chinese Physics C2024，48，2： | 0 |
| 8 | 双针床横机上1+1罗纹线圈单元的几何模型显示文摘针织物的性能主要取决于纱线线圈长度和线圈形状。线圈长度很大程度上是是在线圈形成时由织机上的三角配置和纱线张力所决定。另一方面,线圈形态取决于针织物的松弛处理。如果清楚了影响线圈长度的可变因素和编织区域内各可变因素间的相互作用,就可预知线圈长度。 | S.Mukherjee S.K.Punj 刘潇(译) | 2011 | 国际纺织导报2011，39，12： | 0 |
| 9 | Reverse mode switching of the random laser emission in dye doped liquid crystals under homogeneous and inhomogeneous electric fields显示文摘We report the observation of electric field induced random lasing in a dye doped liquid crystal system. This was achieved by using a liquid crystal host with negative dielectric anisotropy doped with laser dye PM 597 in a 75 μm cell with a homeotropic alignment layer. In the absence of an applied field, only amplified spontaneous emission was observed since the liquid crystal orientation was uniform. However, application of a field resulted in a fieldinduced planar-like configuration with local nonuniformity in liquid crystal orientation. This led to random lasing in the energized state(voltage greater than a transition threshold). The onset of lasing occurs by application of either a spatially homogenous or a spatially inhomogeneous electric field across the liquid crystal. The characteristics of the emission spectra as a function of different(i) dye concentration and(ii) applied voltage were investigated using nanosecond pulsed laser excitation at 532 nm. The effects of using an inhomogeneous field were compared to the use of a homogenous field and reported. It is shown that the spatial configuration can be used to alter the emission spectra of the system. The work is used to suggest a new configuration, referred to here as'reverse mode,' for liquid crystal-based random lasers. This new configuration may provide additional avenues for their use in commercial devices. | M.Shasti P.Coutino S.Mukherjee A.Varanytsia T.Smith A.P.Luchette L.Sukhomlinova T.Kosa A.Munoz B.Taheri | 2016 | Photonics Research2016，4，1： | 0 |
| 10 | HIGH DIELECTRIC CONSTANT COMPOSITE BASED ON CHLOROPHYLL A ENTRAPPED NANOPOROUS SILICA GEL显示文摘Chlorophyll a(naturally occurring Mg porphyrene)has been entrapped in nano/porous silica gel using sol-gel method at room temperature,producing a stable composite.HR TEM observationreveals regular nanoscale[around 15-20 nm diameter]distribution of aggregated polycrystalinechlorophylla within porous silica matrix.UV-vis study also corroborates the presence of variousaggregated chlorophyll a species within the system.Low field measurement shows almost 400times enhancement of dielectric constant(1700)with incorporation of only 0.125 mg/ml of chlorophyll and the loss is 0.5 at room temperature at 100 Hz.The dielectric constant of the composite reaches 2500 as chlorophyll concentration becomes 1 mg/ml.Observed strong space charge response to the external field and strong frequency dispersion of the dielectric properties ofthe composite can be attributed to the long-range electron delocalization[nomadic polarization]in chlorophyl a aggregates.The electric modulus(M*)formalism used in this study enabled us todistinguish and separate various relaxation processes.It is found that with increasing chlorophyll concentration D.C.relaxation time decreases exponentially at room temperature.It is shown that observed relaxations do not perfectly follow the Debye response in high frequency region due toheterogeneous distribution of chlorophyll aggregates.The low values of room temperature acti-vation energy calculated from Arrhenius plot reveal that polaronic hopping phenomena is absent at grain-interfacial region due to low thermal energy. | J.S.MANNA M.K.MITRA S.MUKHERJEE G.C.DAS | 2012 | Journal of Advanced Dielectrics2012，2，3： | 0 |
