Carboxylic‐Acid Functionalized Multiwalled Carbon Nanotube‐Alkane‐Based Resistive Temperature Sensor for Cold Chain Applications

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents a reversible temperature sensor with high switching ratio, ∼103. The device is fabricated using PET‐ITO and carbon nanotube dispersions in alkane. Considering its application in cold chain logistics, a proof‐of‐concept with LED is showcased. Thus, a temperature drop below the threshold temperature (crystallization temperature of the

On instanton effects in the operator product expansion

open access: yesJournal of High Energy Physics, 2017
We revisit the computation of instanton effects to various correlation functions in N = 4 $$ \mathcal{N}=4 $$ SYM and clarify a controversy existing in the literature regarding their consistency with the OPE and conformal symmetry.

Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology

open access: yesAdvanced Engineering Materials, EarlyView.
We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control

Conformal symmetry of QCD in d-dimensions

open access: yesPhysics Letters B, 2019
QCD in d=4−2ϵ space-time dimensions possesses a nontrivial critical point and there are good reasons to expect that this theory restricted to the gauge-invariant subsector is conformally invariant.

Classical and Nonclassical symmetries of the (2+1)-dimensional Kuramoto-Sivashinsky equation

open access: yes, 2011
In this paper, we have studied the problem of determining the largest possible set of symmetries for an important example of nonlinear dynamical system: the Kuramoto-Sivashinsky (K-S) model in two spatial and one temporal dimensions.

Symmetry operators of Kranz products

open access: yesJournal of Combinatorial Theory, Series A, 1971
AbstractIn this paper we consider the linear algebraic analogs of certain classes of combinatorial identities connected with the problem of enumeration under group actions. The relationship between symmetry operators of Kranz products with abelian characters and their underlying subgroups is explored. Some applications to combinatorics are discussed.

Enhancing Strength and Electrical Conductivity in Al–Zr–Sc Conductor Alloys Through Sn and Sr Microalloying and Two‐Step Aging Treatment

open access: yesAdvanced Engineering Materials, EarlyView.
Trace additions of Sn and Sr combined with a two‐step aging treatment are shown to enhance the microstructure and performance of Al–Zr–Sc conductor alloys. Strength and electrical conductivity increase concurrently through accelerated precipitation of fine Al3(Sc, Zr) precipitates and improved dislocation resistance, offering a cost‐effective pathway ...

Perspectives on anomaly resolution

open access: yesJournal of High Energy Physics, 2023
We examine in detail the process of resolving ’t Hooft anomalies by extending the symmetry of a theory. Specifically, we interpret the ingredients of existing prescriptions for anomaly resolution as the addition of topological operators with designated ...
