Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives

Advanced Materials, EarlyView.
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

Self‐Cooling Molecular Spin Qudits

Advanced Materials, EarlyView.
A material made of [GdEr] molecular dimers can encode a qudit and perform as a magnetic refrigerant. Microwave resonant pulses coherently manipulate its 16 spin states, while direct demagnetization measurements cool the material and a device down to temperatures below 1 K.

Electrically Readable Lateral Flow Assay Using Organic Transistors for Diagnostic Applications

Advanced Materials, EarlyView.
Electrolyte‐gated organic field‐effect transistors (EGOFETs) are integrated with lateral flow (LF) paper fluidics to create a reusable, portable, and low‐cost point‐of‐care (PoC) diagnostic test. The devices are validated for Human Immunoglobulin G detection, achieving high sensitivity (0.1 fm), selectivity, and reproducibility with rapid results in 20–

A Biochar‐Based Composite Hydrogel Microenvironment for Enhanced Biocatalysis

Advanced Materials, EarlyView.
This work presents the synthesis of a polyacrylamide hydrogel wherein biomass‐derived biochar is co‐encapsulated with the enzyme horseradish peroxidase (HRP). The resulting composite hydrogel possesses balanced electron‐rich and electron‐deficient domains, creating an optimal microenvironment that concentrates both hydrogen peroxide and phenol ...

Hardy's inequality in unbounded domains

Topological Methods in Nonlinear Analysis, 2001
Let \(\Omega\) be a domain in \(\mathbb R^N\) \((N \geq 3)\) with non-empty boundary \(\partial \Omega\) and let \(\delta (x) : = \text{ dist} (x, \partial \Omega)\), \(x \in \mathbb R^N\). Denote by \(D^{1, 2}_{\varepsilon} (\Omega)\) the completion of \(D (\Omega)\) with respect to the inner product \((u, v) := \int_{\Omega} \delta^{\varepsilon ...

Positive polynomials on unbounded domains

, 2017
Certificates of non-negativity such as Putinar's Positivstellensatz have been used to obtain powerful numerical techniques to solve polynomial optimization (PO) problems. Putinar's certificate uses sum-of-squares (sos) polynomials to certify the non-negativity of a given polynomial over a domain defined by polynomial inequalities.

A Colloidal Quantum Dot Thermistor and Bolometer

Advanced Materials, EarlyView.
This work introduces colloidal quantum dot thermistors employing a potential barrier structure to tune the activation energy of transport and hence the temperature coefficient of resistance (TCR). Upon integration with plasmonic absorbers, the CQD‐based bolometer device enables room‐temperature wavelength‐selective photodetection across the mid‐ to ...
