| 4 | 环锭纱和喷气纱在不同组织结构针织物中的性能分析显示文摘针织是织物制备中仅次于机织的第二大技术。针织技术多种多样,产品因具有良好的抗皱性、较好的合身性和拉伸性,而在市场上越来越受欢迎。针织工艺被广泛地用于制作内衣、紧身裤、裤子、毛衣、西装和外套。一些针织物被用于制备成品服装,如袜子、毛衣和内衣等。线圈长度在针织物外形尺寸中起着关键作用。通过缩短线圈长度可以形成更紧凑、紧密的结构。可通过调整织物的歪斜度和线圈长度之间的比例来控制织物的紧度。单面纬平针织物尺寸参数通常取决于纱线线密度和织物密度。 | S.Geete S.Shah V.S.Shivankar P.P.Raichurkar 林活跃(译) 赵俐(校) | 2020 | 国际纺织导报2020,48,7: | 0 |
| 5 | Comparative assessment of mechanical and chemical fluid diversion techniques during hydraulic fracturing in horizontal wells显示文摘The application of fluid diversion during hydraulic fracturing is an evolving technology and has become popular amongst E&P operators over the past few years.The primary objective of the fluid diversion is to improve hydraulic fracturing treatment by increasing stimulated reservoir volume and improving hydrocarbon recovery.This is possible by achieving any of the following objectives:creating uniform distribution of treatment slurry within the target zone;treating unstimulated and under-stimulated zones;or by increasing fracture density by creating a complex fracture network.The fluid diversion application is also helpful in decreasing the number of stages(by increasing stage length)for multi-stage plug-n-perf(PnP)fracturing treatment.It is also applied to prevent fracture-driven interactions between adjacent wells,which is currently a major issue,especially in shale.In addition,for successful refracturing treatment,the diverter application is essential for isolating the existing fractures and redirecting the treatment slurry to the desired unstimulated zones.The diversion methods can be broadly categorized into the mechanical and chemical diversion.Several established mechanical diversion techniques are frac plugs,expandable casing patches,expandable liners,swellable packers,straddle packer assembly,sand plugs,frac sleeves,perforation ball sealers,and limited entry technique.The different chemical diversion techniques are particulates,fibers,gels,surfactants,perforation pods,and composite diverting.This paper describes the current status of established mechanical and chemical diverter technologies and examines their comparative advantages and challenges.Various techniques are suitable for diverter application,but the technique is selected based on the desired objective and conditions of the wellbore and reservoir.The general guidelines for selecting diversion techniques and operational considerations are also provided in the paper.The diagnosis of diversion treatment plays an essential role in diversion technique selection and optimization of selection parameters for the subsequent treatments.Therefore,the application of conventional surface pressure monitoring techniques and advanced diagnostic tools to evaluate diversion effectiveness are briefly described.Presently no standard laboratory testing method is established for the performance evaluation of diverting agents.Therefore,researchers have implemented various laboratory methods,which are briefly summarized in the paper.Significant insight into the diversion technology and guidelines for its selection and successful implementation is provided to help engineers to increase the effectiveness of hydraulic fracturing treatments.The limitations of individual diversion techniques are clarified,which provide the future scope of research for improvement in various diversion technologies. | Maunish S.Shah Subhash N.Shah | 2023 | Petroleum Science2023,20,6: | 0 |
| 6 | Intersection of Inorganic Chemistry and Nanotechnology for the Creation of New Cancer Therapies显示文摘CONSPECTUS:Since its discovery in 1965,the inorganic drug cisplatin has become a mainstay of cancer therapies and has inspired many platinum(Pt)-based compounds to solve various issues of toxicity and limitations associated with the original cisplatin.However,many of these drugs/prodrugs continue to be plagued by an array of side effects,limited circulation,and half-life and off-target effects.To solve this issue,we have constructed an array of platinum-based prodrugs on a Pt(IV)skeleton,which provides more favorable geometry and hydrophobicity,easier functionalization,and ultimately better targeting abilities.Each of these Pt(IV)prodrugs aims to either combine cisplatin with other agents for a combination therapeutic effect or improve the targeting of cisplatin itself,all for the more effective treatment of specific cancers.Our developed prodrugs include Platin-A,which combines cisplatin with the anti-inflammatory agent aspirin,Platin-M,which is functionalized with a mitochondria-targeting moiety,and Platin-B and Platin-Cbl,which combine cisplatin with components to combat cellular resistance to chemotherapy.At the same time,however,we recognize the crucial role of nanotechnology in improving the efficacy of cisplatin prodrugs and other inorganic compounds for the treatment of cancers.We describe several key benefits provided by nanomedicine that vastly improve the reach and utility of cisplatin prodrugs,including the ability of biodegradable polymeric nanoparticles(NPs)to deliver these agents with precision to the mitochondria,transport drugs across the blood−brain barrier,and target cisplatin prodrugs to specific cancers using various ligands.In addition,we highlight our progress in the engineering of innovative new polymers to improve the release patterns,pharmacokinetics,and dosages of cancer therapies.In this Account,we aim to describe the growing need for collaboration between the fields of inorganic chemistry and nanotechnology and how new advancements can not only improve on traditional chemotherapeutic agents but also expand their reach to entirely new subsets of cancers.In addition to detailing the design and principles behind our modifications of cisplatin and the efficacy of these new prodrugs against aggressive,cisplatin-resistant,or metastatic cancers,we also shed light on nanotechnology’s essential role in protecting inorganic drugs and the human body from one another for more effective disease treatment without the off-target effects with which it is normally associated.We hope that this perspective into the important intersection between inorganic medicinal chemistry and nanotechnology will inspire future research on cisplatin prodrugs and other inorganic agents,innovative polymer and NP design,and the ways in which these two fields can greatly advance cancer treatment. | Anuj S.Shah Bapurao Surnar Nagesh Kolishetti Shanta Dhar | 2022 | Accounts of Materials Research2022,3,3: | 0 |
| 7 | Safe surgical zone during TORS radical tonsillectomy:An anatomical and radiological study显示文摘Objective:Parapharyngeal space contains intricate vascular anatomy(external and internal carotid arteries)that might be inadvertently injured during the dissection in this plane.None of the bony landmarks can be used during the transoral robotic surgery(TORS)radical tonsillectomy as these landmarks lie lateral to the internal carotid artery(ICA)and external carotid artery(ECA)in transoral approach.Our study aims to identify the safe surgical limits during the dissection of parapharyneal space in TORS radical tonsillectomy and to correlate the same with radiological study.Material and methods:Fifteen cadavers(30 head and neck regions)and 50 CT-Angiogram of neck(100 head and neck regions)were included in the anatomical and radiological study respectively.The vertical midpoint of anterior tonsillar pillar(palatoglossus muscle)was taken as the reference point and all the measurements were done at the level of reference point both for anatomical and radiological study.Distance between tonsillar fossa and ECA,distance between tonsillar fossa and ICA,relation between ECA and styloglossus and relation between ICA and stylopharyngeus at reference level were studied.Results:The mean distance of ECA from the tonsillar fossa at the reference point was 18.2 mm in the anatomical study and 16.2 mm in the radiological study.The mean distance of ICA from the tonsillar fossa was 23.4 mm and 23.3 mm in the anatomical study and radiological study.There was no significant difference between the anatomical and radiological findings for both the mean distance between ECA and ICA to the tonsillar fossa(p value was 0.45 and 0.30 respectively).ECA was located posterolateral to styloglossus in 24 cases(80.0%)and 79 cases(79.0%)in the anatomical and radiological study respectively.ICA was found posterolateral to stylopharyngeus in 21 cases(70.0%)and 69 cases(69.0%)in the anatomical and radiological study respectively.Conclusion:The muscular plane between styloglossus and stylopharyngeus can be used as an envelope to locate the ECA and ICA that lie medial to these critical vascular structures during TORS.We propose to divide the parapharyngeal space into two compartments(anterior and posterior)based on the surgical perspective of inside-out anatomy.The anterior compartment houses styloglossus muscle with ECA posterolateral to it and the posterior compartment has stylopharyngeus and ICA posterolateral to it. | J.G.Aishwarya Ashish S.Shah Satish Nair Savith Kumar Swetha Kumar K.V.R.Brijith Namrata Srivastava Ameena Ibrahim | 2020 | Laparoscopic, Endoscopic and Robotic Surgery2020,3,2: | 0 |
| 8 | Graphene/SrTiO_(3) hetero interface studied by X-ray photoelectron spectroscopy显示文摘The present paper focuses on study of graphene and strontium titanate(SrTiO_3 or STO) interface. An ambient pressure chemical vapour deposition(AP-CVD) setup is used to grow graphene on STO(110)substrates in the presence of methane, argon and hydrogen gases at 1000 °C for 4 h. Raman spectroscopy measurements confirm the presence of graphene on STO substrates due to the existence of typical D and G peaks referring to graphene. These characteristic peaks are missing in the spectrum for bare substrates.X-ray photoelectron spectroscopy(XPS) is carried out for elemental analysis of samples, and study their bonding with STO substrates. We employed the valence band spectrum to calculate the valence band offset(VBO) and conduction band offset(CBO) at the G-STO interface. Also, we present an energy band diagram for Bi-layer and ABC(arranging pattern of carbon layers) stacked graphene layers. | S.Karamat C.Ke U.Y.Inkaya Rizwan Akram Ilker Yildiz S.Shah Zaman A.Oral | 2016 | Progress in Natural Science:Materials International2016,26,4: | 0 |
