| 1 | Surface plasmon polariton at the interface of dielectric and graphene medium using Kerr effect显示文摘We theoretically investigate the control of surface plasmon polariton(SPP) generated at the interface of dielectric and graphene medium under Kerr nonlinearity. The controlled Kerr nonlinear signal of probe light beam in a dielectric medium is used to generate SPPs at the interface of dielectric and graphene medium. The positive, negative absorption, and dispersion properties of SPPs are modified and controlled by the control and Kerr fields. A large amplification(negative absorption) is noted for SPPs under the Kerr nonlinearity. The normal/anomalous slope of dispersion and propagation length of SPPs is modified and controlled with Kerr nonlinearity. This leads to significant variation in slow and fast SPP propagation. The controlled slow and fast SPP propagation may predict significant applications in nano-photonics, optical tweezers, photovoltaic devices, plasmonster, and sensing technology. | Bakhtawar Muhammad Haneef B A Bacha H Khan M Atif | 2018 | Chinese Physics B2018，27，11： | 3 |
| 2 | Surface plasmon polaritons induced reduced hacking显示文摘There is always need for secure transmission of information and simultaneously compact-size photonic circuits. This can be achieved if surface plasmon-polaritons(SPPs) are used as source of information, and the reduced hacking as the transmission phenomenon. In this article, an SPP-based reduced hacking scheme is presented at interface between atomic medium and metallic conductor. The SPP propagation is manipulated with conductivity of the metal. The delay or advance of the SPP is found to create nanosecond time gap which can be used for storing and sending the information safely. The reduced hacking is further modified with conductivity of the metal and the control parameters of the atomic medium. | Bakhtawar Muhammad Haneef Humayun Khan | 2021 | Chinese Physics B2021，30，6： | 0 |
| 3 | Birefringence via Doppler broadening and prevention of information hacking显示文摘We propose a new scheme for the coherent control of birefringent light pulses propagation in a four-level atomic medium. We modify the splitting of a light pulse by controlling the electric and magnetic responses. The Doppler broadening effect is also noted on the propagation of the birefringent pulses. The dispersions of the birefringence beams are oppositely manipulated for delay and advancement of time at a Doppler width of 10γ. A time gap is created between the birefringence beams, which protects from hacking of information. The time gap is then closed to restore the pulse into the original form by a reverse manipulation of the dispersion of the birefringence beams, i.e., introducing another medium whose transfer function is the complex conjugate of that of the original medium. The results are useful for secure communication technology. | Humayun Khan Muhammad Haneef Bakhtawar | 2018 | Chinese Physics B2018，27，1： | 0 |

| 5 | The Effects of Spherical Surface and Laser Polarization on the Photodetachment Cross Section of H^-显示文摘We report the combined effects of laser polarization and curvature of the spherical surface on the detached electron spectra from H-.The Theoretical imaging method is used as a tool of investigation.The photodetachment cross sections for various polarization angles,radii of curvatures and inter ion surface distances are displayed.The analysis of the spectra reveals that the laser polarization angle θL,curvature of the surface rc and inter ion surface distance d strongly affect oscillations in the spectra.Therefore,a fine control on the laser polarization and that of curvature in the surface can be used to control oscillations in the photodetachment of negative ions. | Muhammad Haneef Suneela Arif Jehan Akbar Nasrullah Shah Muhammad Zahir Aneela Shamim Hameed Ullah | 2013 | Communications in Theoretical Physics2013，59，3： | 0 |
| 6 | Efficient two-dimensional atom localization in a five-level conductive chiral atomic medium via birefringence beam absorption spectrum显示文摘We have theoretically investigated two-dimensional atom localization using the absorption spectra of birefringence beams of light in a single wavelength domain.The atom localization is controlled and modified through tunneling effect in a conductive chiral atomic medium with absorption spectra of birefringent beams.The significant localization peaks are investigated in the left and right circularly polarized beam.Single and double localized peaks are observed in different quadrants with minimum uncertainty and significant probability.The localized probability is modified by controlling birefringence and tunneling conditions.These results may be useful for the capability of optical microscopy and atom imaging. | Sajid Ali Muhammad Idrees Bakth Amin Bacha Arif Ullah Muhammad Haneef | 2021 | Communications in Theoretical Physics2021，73，1： | 0 |
| 7 | Space–time cloaks through birefringent Goos–H?nchen shifts显示文摘We report a theoretical demonstration for the creation of space–time holes based on birefringence of reflection,transmission, and the Goos–H?chen(GH) shifts from a chiral medium. We observed space–time holes in the reflection, transmission, and their corresponding GH-shifted beams. Two space–time holes are clearly detected in the regions of 0 < t ≤ 5τ_0 and-5 w ≤ y ≤ 5 w, as well as in the regions of-5τ_0≤ t ≤ 0 and-5 w ≤ y ≤ 5 w.These space–time holes hide objects and information contents from observers and hackers. The objects and information contents are completely undetectable, and thus events can be cloaked. The results of this paper have potential applications in the invisibility of drone technology and secure communication of information in telecom industries. | Humayun Khan Muhammad Haneef Bakhtawar | 2019 | Chinese Optics Letters2019，17，3： | 0 |

| 9 | Mini-organs with big impact:Organoids in liver cancer studies显示文摘Hepatocellular carcinoma,the most common primary liver cancer and a leading cause of death,is a difficult disease to treat due to its heterogeneous nature.Traditional models,such as 2D culture and patient-derived xenografts,have not proven effective.However,the development of 3D culture techniques,such as organoids,which can mimic the tumor microenvironment(TME)and preserve heterogeneity and pathophysiological properties of tumor cells,offers new opportunities for treatment and research.Organoids also have the potential for biomarker detection and personalized medication,as well as genome editing using CRISPR/Cas9 to study the behavior of certain genes and therapeutic interventions.This review explores to-the-date development of organoids with a focus on TME modeling in 3D organoid cultures.Further,it discusses gene editing using CRISPR/Cas9 in organoids,the challenges faced,and the prospects in the field of organoids. | MUHAMMAD BABAR KHAWAR YAJUN WANG ANEEQA MAJEED ALI AFZAL KABEER HANEEF HAIBO SUN | 2023 | Oncology Research2023，31，5： | 0 |
| 10 | Property-performance relationship of core-shell structured black TiO_(2) photocatalyst for environmental remediation显示文摘Understanding the relationship between the properties and performance of black titanium dioxide with core-shell structure(CSBT)for environmental remediation is crucial for improving its prospects in practical applications.In this study,CSBT was synthesized using a glycerol-assisted sol-gel approach.The effect of different water-to-glycerol ratios(W:G=1:0,9:1,2:1,and 1:1)on the semiconducting and physicochemical properties of CSBT was investigated.The effectiveness of CSBT in removing phenolic compounds(PHCs)from real agro-industrial wastewater was studied.The CSBT synthesized with a W:G ratio of 9:1 has optimized properties for enhanced removal of PHCs.It has a distinct coreshell structure and an appropriate amount of Ti3+cations(11.18%),which play a crucial role in enhancing the performance of CSBT.When exposed to visible light,the CSBT performed better:48.30%of PHCs were removed after 180 min,compared to only 21.95%for TiO_(2) without core-shell structure.The CSBT consumed only 45.5235 kWh/m^(3) of electrical energy per order of magnitude and cost$2.4127 per unit volume of treated agro-industrial wastewater.Under the conditions tested,the CSBT demonstrated exceptional stability and reusability.The CSBT showed promising results in the treatment of phenols-containing agro-industrial wastewater. | Sajjad Haider Rab Nawaz Muzammil Anjum Tahir Haneef Vipin Kumar Oad Salah Uddinkhan Rawaiz Khan Muhammad Aqif | 2023 | Frontiers of Environmental Science & Engineering2023，17，9： | 0 |
| 11 | Surface Plasmon Polariton Fizeaus Dragging: via Relative Rotational Sensing显示文摘A new scheme focusing on the surface plasmon polariton interferometry between the metal and dielectric interface is introduced. The phase shift is measured by using surface plasmon polariton wave, generated at the interface of metallic and dielectric media. The phase shift of SPPs is modi?ed under phase and amplitude control of complex conductivity for interferometry. The control ?elds strongly in?uence the phase shift of SPPs for detection of molecular motion. The phase shift of SPPs is further modi?ed by Plasmon polariton Fizeaus dragging effect. We measure 20%–25%fractional change in delay and their phases shift between two left and right SPPs modes. Our results may have signi?cant applications in sensor interferometer technology. | Bilal Shoaib Muhammad Haneef Humayun Khan Bakhtawar | 2019 | Communications in Theoretical Physics2019，71，4： | 0 |
| 12 | A Periglacial Palaeoenvionment in the Upper Carboniferous-Lower Permian Tobra Formation of the Salt Range,Pakistan显示文摘The Upper Carboniferous—Lower Permian(Upper Pennsylvanian-Asselian) Tobra Formation is exposed in the Salt and Trans Indus ranges of Pakistan.The formation exhibits an alluvial plain(alluvial fan-piedmont alluvial plain) facies association in the Salt Range and Khisor Range.In addition,a stream flow facies association is restricted to the eastern Salt Range.The alluvial plain facies association is comprised of clast-supported massive conglomerate(Gmc),diamictite(Dm)facies,and massive sandstone(Sm) Hthofacies whereas the stream flow-dominated alluvial plain facies association includes fine-grained sandstone and siltstone(Fss),fining upwards pebbly sandstone(Sf),and massive mudstone(Fm) Hthofacies.The lack of glacial signatures(particularly glacial grooves and striatums) in the deposits in the Tobra Formation,which are,in contrast,present in their timeequivalent and palaeogeographically nearby strata of the Arabian peninsula,e.g.the AI Khlata Formation of Oman and Unayzah B member of the Saudi Arabia,suggests a pro-to periglacial,i.e.glaciofluvial depositional setting for the Tobra Formation.The sedimentology of the Tobra Formation attests that the Salt Range,Pakistan,occupied a palaeogeographic position just beyond the maximum glacial extent during Upper Pennsylvanian-Asselian time. | Irfan U.JAN Shahid IQBAL Sarah J.DA VIES Jan A.ZALASIEWICZ Michael H.STEPHENSON Michael WAGREICH Muhammad HANEEF Muhammad HANIF Sajjad AHMAD | 2017 | Acta Geologica Sinica(English Edition)2017，91，3： | 0 |
