Remarkably Enhanced Lattice Oxygen Participation in Perovskites to Boost Oxygen Evolution Reaction.
Enhancing the participation of the lattice oxygen mechanism (LOM) in several perovskites to significantly boost the oxygen evolution reaction (OER) is daunting. With the rapid decline in fossil fuels, energy research is turning...
Safety of beta-blocker and calcium channel blocker antihypertensive drugs in pregnancy
BACKGROUND: Beta-blocker (BB) and calcium channel blocker (CCB) antihypertensive drugs are commonly used in pregnancy. However, data on their relative impact on maternal and foetal outcomes are limited. We leveraged genetic...
Exploring Factors Associated with Women's Willingness to Provide Digital Fingerprints in Accessing Healthcare Services
Digital fingerprints are increasingly used for patient care and treatment delivery, health system monitoring and evaluation, and maintaining data integrity during health research. Yet, no evidence exists about the use of...
Factors associated with mobile phone usage to access maternal and child healthcare among women of urban slums in Dhaka, Bangladesh
INTRODUCTION: With the acute shortage of human resources and infrastructure, mobile phones can be a critical tool for accessing health services and strengthening health systems in Bangladesh. Yet, there is a scarcity of evidence...
Fully Printed Organic-Inorganic Nanocomposites for Flexible Thermoelectric Applications.
Thermoelectric materials, capable of interconverting heat and electricity, are attractive for applications in thermal energy harvesting as a means to power wireless sensors, wearable devices, and portable electronics. However...
Sleep Disordered Breathing, Obesity and Atrial Fibrillation
It remains unclear whether the association between obstructive sleep apnoea (OSA), a form of sleep-disordered breathing (SDB), and atrial fibrillation (AF) is causal or mediated by shared co-morbidities such as obesity. Existing...
Nylon-11 nanowires for triboelectric energy harvesting
YS Choi, S Kar-Narayan
Oct 22, 2020
Triboelectric energy harvesting from ambient mechanical sources relies on motion-generated surface charge transfer between materials with different electron affinities. In order to achieve highly efficient energy harvesting...
Caloric materials near ferroic phase transitions
X Moya, S Kar-Narayan, ND Mathur
Sep 13, 2017
A magnetically, electrically or mechanically responsive material can undergo significant thermal changes near a ferroic phase transition when its order parameter is modified by the conjugate applied field. The resulting...
A Key-Based Mutual Authentication Framework for Mobile Contactless Payment System Using Authentication Server
This paper presents a framework for mutual authentication between a user device and a point of sale (POS) machine using magnetic secure transmission (MST) to prevent the wormhole attack in Samsung pay. The primary attribute of...
A Survey on Contactless Smart Cards and Payment System
In recent years, contactless transactions have risen rapidly. It includes NFC, MST, contactless cards, and many other payment methods. These payment methods have certain security issues, and attackers are in a regular search for...
Early Prediction of Heart Diseases using Naive Bayes Classification Algorithm and Laplace Smoothing Technique
Nowadays, medical diseases are one of the primary causes of death, and it is one the major concerns of developed countries. So, the disease identification process needs a lot of attention since if the diseases are idenfied at...
Mechanical Energy Harvesting Performance of Ferroelectric Polymer Nanowires Grown via Template-Wetting.
Nanowires of the ferroelectric co-polymer poly(vinylidenefluoride-co-triufloroethylene) [P(VDF-TrFE)] are fabricated from solution within nanoporous templates of both "hard" anodic aluminium oxide (AAO) and "soft" polyimide (PI)...
