Fluorogenic Sydnones for Bioorthogonal Labeling of DNA

Chemistry – A European Journal, EarlyView.
Conjugates of sydnones with cyanine‐styryl dyes combine bioorthogonal reactivity with fluorogenicity. The reactivity with bicyclo[6.1.0]non‐4‐yne (BCN)‐modified DNA showed second‐order rate constants of up to k2 = 2,300 M−1s−1 and fluorescence turn‐on by one magnitude of order.

Solar Based Thermoelectric Refrigerator Using Peltier Module

International Journal for Research in Applied Science and Engineering Technology, 2022
Abstract: Refrigerators being used nowadays, utilize a compressor and coolant as a working fluid for the transmission of the heat. Thermal energy is absorbed and released as the coolant used goes through expansion and compression and its state changes from liquid to vapor and vice-versa.

Introduction of a Double‐Headed Nucleotide Into G‐Quadruplex DNA: Position‐Dependent Stabilization and Structural Insights

Chemistry – A European Journal, EarlyView.
A double‐headed bis‐guanine (G) nucleotide (GG) was evaluated as a noncanonical building block in G‐quadruplexes (G4s). Biophysical and computational analyses reveal that GG can directly participate in G‐tetrads and strongly stabilize G4s in a position‐ and topology‐dependent manner. These findings establish design rules for using GG to engineer highly

Investigation of thermoelastic properties of Peltier thermoelectric module branches

Технологія та конструювання в електронній апаратурі, 2005
Studies of the thermoelastic properties of Peltier thermoelectric modules have been carried out, taking into account the functional dependence of Young’s modulus and the coefficients of thermal expansion on the chosen crystallographic direction in cubic,

STUDY OF ELECTRICITY PRODUCTION USING PELTIER MODULE

Electrical and data processing facilities and systems
Relevance Alternative energy based on wind and solar power is nowadays quite common, but the dependence on weather and time of day, high initial cost and difficulties in utilization make us think about other sources of renew- able energy. The module under consideration, based on the Seebeck effect, generates power in small watts, which can be applied ...

Nanostructured Optical Superabsorbers from Carbon Nanotube Forest for Heat Management Using Environmental Blackbody Radiation from the Visible to Mid‐Infrared

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Our computational model of the optical absorption from multiwalled carbon nanotubes suggests the optical absorption depends strongly on the in‐plane electrical conductivity, and weakly on the through‐plane conductivity. Such strong absorption enables solar‐to‐thermal conversion for heat scavenging in cold climates and radiative cooling in hot climates,

Artificial structures for human‐machine interfaces with closed‐loop interaction

FlexMat, EarlyView.
Artificial structures bridge sensing and feedback in closed‐loop human‐machine interfaces by providing geometry‐enabled mechanical and functional programmability. This review maps the role of artificial structures in diverse sensing modalities and feedback strategies, and illustrates their integration into closed‐loop interaction systems, highlighting ...

An Open‐Source, Reproducible MRI Data Acquisition and Reconstruction Workflow Using Pulseq: Multi‐Site and Cross‐Vendor Validation

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Reproducibility in MRI is limited by variability in data acquisition, formatting, and reconstruction across sites and vendors. This work aimed to mitigate these challenges through an open‐source, vendor‐independent workflow originally developed for the 2023–24 ISMRM Repeat It with Me: Reproducibility Team Challenge.

Adaptive Sliding‐Mode Control of a Perturbed Diffusion Process With Pointwise In‐Domain Actuation

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT A sliding mode–based adaptive control law is proposed for a class of diffusion processes featuring a spatially‐varying uncertain diffusivity and equipped with several point‐wise actuators located at the two boundaries of the spatial domain as well as in its interior.
