1Atomic and Close-to-Atomic Scale Manufacturing:A Review on Atomic Layer Removal Methods Using Atomic Force Microscopy显示文摘Manufacturing at the atomic scale is the next generation of the industrial revolution.Atomic and close-to-atomic scalemanufacturing(ACSM)helps to achieve this.Atomic force microscopy(AFM)is a promising method for this purposesince an instrument to machine at this small scale has not yet been developed.As the need for increasing the number ofelectronic components inside an integrated circuit chip is emerging in the present-day scenario,methods should be adoptedto reduce the size of connections inside the chip.This can be achieved using molecules.However,connecting moleculeswith the electrodes and then to the external world is challenging.Foundations must be laid to make this possible for thefuture.Atomic layer removal,down to one atom,can be employed for this purpose.Presently,theoretical works are beingperformed extensively to study the interactions happening at the molecule-electrode junction,and how electronic transportis affected by the functionality and robustness of the system.These theoretical studies can be verified experimentally only if nano electrodes are fabricated.Silicon is widely used in the semiconductor industry to fabricate electronic components.Likewise,carbon-based materials such as highly oriented pyrolytic graphite,gold,and silicon carbide find applications inthe electronic device manufacturing sector.Hence,ACSM of these materials should be developed intensively.This paperpresents a review on the state-of-the-art research performed on material removal at the atomic scale by electrochemical andmechanical methods of the mentioned materials using AFM and provides a roadmap to achieve effective mass productionof these devices.Paven Thomas Mathew Brian J.Rodriguez Fengzhou Fang 2020Nanomanufacturing and Metrology2020,3,3:9
2Characterization of the Nanoscale Microstructure of an Immersion Silver on Sputtered Copper显示文摘Silver has grown its attraction of the scientists in microelectronic field recently. Electrochemical deposition of silver onto copper substrates by immersion method has been one of the keen topics. In this study, ethanol was used as the plating solution in which some chemicals were added. The silver deposits were characterized by a field emission scanning electron microscopy (FESEM), an atom force microscope (AFM), a transmission electron microscope (TEM) and a selected area electron diffraction (SAED). It was found that silver immersion using ethanol-based bath has good coverage feature. The highlands of the copper substrate are coated by silver particles whose sizes are around 12 nm, but those sizes at low-lying lands are a little smaller.TANG Dian WEI Zhe-Liang SHAO Yan-Qun YOU Shao-Xin O'KEEFE Mathew O' KEEFE Thomas 2005Chinese Journal of Structural Chemistry2005,24,8:6
3Cystic lesions of peripheral nerves:Are we missing the diagnosis of the intraneural ganglion cyst?显示文摘AIM To highlight the salient magnetic resonance imaging(MRI) features of the intraneural ganglion cyst(INGC) of various peripheral nerves for their precise diagnosis and to differentiate them from other intra and extraneural cystic lesions.METHODS A retrospective analysis of the magnetic resonance(MR) images of a cohort of 245 patients presenting with nerve palsy involving different peripheral nerves was done.MR images were analyzed for the presence of a nerve lesion,and if found,it was further characterized as solid or cystic.The serial axial,coronal and sagittal MR images of the lesions diagnosed as INGC were studied for their pattern and the anatomical extent along the course of the affected nerve and its branches.Its relation to identifiable anatomical landmarks,intraarticular communication and presence of denervation changes in the muscles supplied by involved nerve was also studied.RESULTS A total of 45 cystic lesions in the intra or extraneurallocations of the nerves were identified from the 245 MR scans done for patients presenting with nerve palsy.Out of these 45 cystic lesions,13 were diagnosed to have INGC of a peripheral nerve on MRI.The other cystic lesions included extraneural ganglion cyst,paralabral cyst impinging upon the suprascapular nerve,cystic schwannoma and nerve abscesses related to Hansen's disease involving various peripheral nerves.Thirteen lesions of INGC were identified in 12 patients.Seven of these affected the common peroneal nerve with one patient having a bilateral involvement.Two lesions each were noted in the tibial and suprascapular nerves,and one each in the obturator and proximal sciatic nerve.An intra-articular connection along the articular branch was demonstrated in 12 out of 13 lesions.Varying stages of denervation atrophy of the supplied muscles of the affected nerves were seen in 7 cases.Out of these 13 lesions in 12 patients,6 underwent surgery.CONCLUSION INGC is an important cause of reversible mono-neuropathy if diagnosed early and surgically treated.Its classic MRI pattern differentiates it from other lesions of the peripheral nerve and aid in its therapeutic planning.In each case,the joint connection has to be identified preoperatively,and the same should be excised during surgery to prevent further cyst recurrence.Jyoti Panwar Anil Mathew Binu P Thomas 2017World Journal of Radiology2017,9,5:5
4Efficacy and safety of liquid nitrogen cryotherapy for treatment of Barrett's esophagus显示文摘AIM To evaluate the efficacy and safety of liquid nitrogen cryotherapy as a primary or rescue treatment for BE,with and without dysplasia,or intramucosal adenocarcinoma (IMC).METHODS This was a retrospective,single-center study carried out in a tertiary care center including 45 patients with BE who was treatment-na?ve or who had persistent intestinal metaplasia(IM),dysplasia,or IMC despite prior therapy.Barrett's mucosa was resected via EMR when clinically appropriate,then patients underwent cryotherapy until eradication or until deemed to have failed treatment.Surveillance biopsies were taken at standard intervals.RESULTS From 2010 through 2014,33 patients were studied regarding the efficacy of cryotherapy.Overall,29 patients (88%) responded to cryotherapy,with 84% having complete regression of all dysplasia and cancer.Complete eradication of cancer and dysplasia was seen in 75% of subjects with IMC; the remaining two subjects did not respond to cryotherapy.Following cryotherapy,15 patients with high-grade dysplasia (HGD) had 30% complete regression,50% IM,and 7% low-grade dysplasia (LGD); one subject had persistent HGD.Complete eradication of dysplasia occurred in all 5 patients with LGD.In 5 patients with IM,complete regression occurred in 4,and IM persisted in one.In 136 cryotherapy sessions amongst 45 patients,adverse events included chest pain (1%),stricture (4%),and one gastrointestinal bleed in a patient on dual antiplatelet therapy who had previously undergone EMR.CONCLUSION Cryotherapy is an efficacious and safe treatment modality for Barrett's esophagus with and without dysplasia or intramucosal adenocarcinoma.Kristen Suchniak-Mussari Charles E Dye Matthew T Moyer Abraham Mathew Thomas J McGarrity Eileen M Gagliardi Jennifer L Maranki John M Levenick 2017World Journal of Gastrointestinal Endoscopy2017,9,9:4
5Survival analysis and mortality predictors of hospitalized severe burn victims in a Malaysian burns intensive care unit显示文摘Background:Prognostic measures to determine burn mortality are essential in evaluating the severity of individual burn victims.This is an important process of triaging patients with high risk of mortality that may be nursed in the acute care setting.Malaysian burn research is lacking with only one publication identified which describes the epidemiology of burn victims.Therefore,the objective of this study was to go one step further and identify the predictors of burn mortality from a Malaysian burns intensive care unit(BICU)which may be used to triage patients at higher risk of death.Methods:This is a retrospective cohort study of all admissions to Hospital Sultan Ismail’s BICU from January 2010 till October 2015.Admission criteria were in accordance with the American Burn Association guidelines,and risk factors of interest were recorded.Data was analyzed using simple logistic regression to determine significant predictors of mortality.Survival analysis with time to death event was performed using the Kaplan-Meier survival curve with log-rank test.Results:Through the 6-year period,393 patients were admitted with a male preponderance of 73.8%.The mean age and length of stay were 35.6(±15.72)years and 15.3(±18.91)days.There were 48 mortalities with an overall mortality rate of 12.2%.Significant risk factors identified on simple logistic regression were total body surface area(TBSA)>20%(p<0.001),inhalation injury(p<0.001)and presence of early systemic inflammatory response syndrome(SIRS)(p<0.001).Survival analysis using Kaplan-Meier survival curve showed similar results with TBSA>20%,presence of SIRS,mechanical ventilation and inhalation injury which were associated with poorer survival(p<0.001).Conclusion:The predictors of mortality identified in a Malaysian BICU were TBSA>20%,early SIRS,mechanical ventilation and inhalation injury which were associated with poorer survival outcome.The immunological response differs from individual patients and influenced by the severity of burn injury.Early SIRS on admission is an important predictor of death and may represent the severity of burn injury.Patients who required mechanical ventilation were associated with mortality and it is likely related to the severity of pulmonary insults sustained by individual patients.This data is important for outcome prognostication and mortality risk counselling in severely burned patients.Henry Tan Chor Lip Jih Huei Tan Mathew Thomas Farrah-Hani Imran Tuan Nur’Azmah Tuan Mat 2019Burns & Trauma2019,7,1:4
