Superior Electrochemical Performance of Two-Dimensional {RGO}/Cu/Cu2O Composite as Anode Material for Lithium-Ion Batteries
No full textIn recent years, graphene has attracted the interest of many researchers working on LIB anode materials owing to its unique 2D structure, thermal stability, and fast electron transfer. In this work, RGO/Cu/Cu2O nanocomposites were synthesized through a hydrothermal procedure. The as-prepared nanocomposites exhibited a high lithium storage capacity with improved cycling stability and great rate performance, i.e., the discharge capacity was 371.8 mAh/g after 100 cycles at a current density of 500 mA/g. These excellent properties were associated with the sheet structure symmetry of graphene enriched with the multifunctional Cu-Cu2O component, which prevented aggregation and accommodated the volume changes of the anode material during the charge–discharge tests. The RGO/Cu/Cu2O composite conferred to the LIB anode the ability to resist electrode cracking. The approach proposed in this paper can be also generalized for the synthesis of other carbon-based anode materials for LIBs

Wideband and High Gain Array Antenna for 5G Smart Phone Applications Using Frequency Selective Surface
No full textThis work presents an eight element array antenna with single layer frequency selective surface (FSS) to obtain high gain. The eight elements are fed by single port. The FSS consists of 14 × 6 unit cells with one unit cell size is 5 × 5 mm2 having wideband behavior. The antenna uses Rogers RT Duroid 5880 substrate and giving very wide bandwidth from 20 GHz to 65 GHz, covering millimeter wave 5G bands (including 28 GHz, 38 GHz and 60 GHz). The designed FSS is showing stop band transmission characteristics below −10 dB threshold from 25 GHz to 42 GHz and 59 GHz to 61 GHz. The eight element antenna integrated with the FSS reflector, which results an improvement in the gain level from 12 dB to 15 dB at 28 GHz, from 10 dB to 12 dB at 38 GHz, and from 9.5 to 11 dB at 60 GHz. The dimensions of the antenna are 65 × 27 × 0.857 mm3. The proposed antenna shows stable gain and directional radiation patterns. The simulation findings are experimentally confirmed, by testing the fabricated prototypes of the proposed antenna system

Fractional investigations of zoonotic visceral leishmaniasis disease with singular and non-singular kernel
No full textKumam, Poom/0000-0002-5463-4581; Khan, Muhammad Altaf/0000-0002-4483-7879Memory has a great impact to study the dynamics of any real epidemic process in a better way. An epidemic model including memory effect is governed by fractional differential equations. in the present paper we explore the dynamics of the zoonotic visceral leishmaniasis (ZVL) disease using fractional derivative in both the Caputo and Atangana-Baleanu sense. the proposed model in the Caputo sense is solved by the well-known method known as modified differential transform method (MDTM), which is efficient and reliable. Further, the solution for the model with Atangana-Baleanu derivative is obtained by the modified Adams-Bashforh method. Numerical simulations are presented by using a different value of the fractional order parameter a. the numerical results obtained through the MDTM and the modified Adams-Bashforh method are reasonable and provide useful information in the non-integer case. Numerical results presented for the fractional order parameter a and in the integer case for the Caputo derivative model are compared with the Runge-Kutta method which gives good agreement. the application of Atangana-Baleanu derivative, the Caputo derivative and the use of the numerical approaches, MDTM, Adams Bashforth and the Runge-Kutta method (for the integer case) for an epidemic model is a novel practice and provides more flexible and deeper information about the complexity of the dynamics of ZVL.Center of Excellence in Theoretical and Computational Science (TaCS-CoE), KMUTT; King Mongkuts University of Technology North Bangkok [KMUTNB-61-GOV-D-68]The authors are thankful to the anonymous reviewers and handling editor for their careful reading and constructive comments that greatly improved the presentation of the paper. the authors acknowledge the financial support provided by the Center of Excellence in Theoretical and Computational Science (TaCS-CoE), KMUTT.

نقوش کے مکاتیب نمبر میں شعر نویسی کی روایت
No full textMaktoobat is a significant part of Urdu literature. At times, Maktoob
writer cannot explain his purpose in simple prose. Therefore, he uses a couplet
to satisfy his objective. In our continent, Persian was popular during 19th
century. These are Persian versus along with Urdu in our Maktoob writers works.
This research paper has selected those makateeb from Naqoosh number which
include versus. Mirza Ghalib has dedicated one Maktoob to Nawab Amin udin Khan
Bahadur wali Loharo. There are 5 Makateeb by Muhammad Hussain Azaad in Makateeb
No of Naqoosh. Among the most popular are: 14 Makateeb by renowed Urdu poet
Amir Menai, 01 Maktoob by Maulana Altaf Hussain dedicated to Nawab Syed Ali
Hasan, 23 Makateeb by Nawab Mohsen-un-Mulk, 2 Makateeb by Jalal Lakhnawi, 44 by
Alama Shibli Naumani, 10 by Shaad Azim Abadi , 5 by Syed Ahmad Dehlvi and 49
Makateeb by Alama Iqbal. All these Makateeb are outstanding examples of Urdu
poetry and prose
