Synergistic Enhancement of Modified‐PVDF Humidity Sensitivity via Chemical Adsorption‐Ionic Conductivity and its Application in Intelligent Powered Air‐Purifying Respirator

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.
The study developed a PVDF/SiO2 humidity sensor with superhydrophobic properties and integrated the humidity sensor into the intelligent powered air‐purifying respirator (IPAPR) for breath monitoring. Coupled with the Gated Recurrent Unit (GRU) machine learning prediction algorithm, it enables feedforward control of the fan to achieve respiratory ...

Isoelectronic Alloying in Zintl Phases Mediated the Avoided Crossing and Phonon Softening

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.
A small amount of Hf doping endows Zr3Ni3Sb4‐Zintl with an unusually low thermal conductivity far exceeding that of similar systems. Two unique phonon mechanisms—avoided crossing and phonon softening—significantly suppress the lattice thermal conductivity. The average thermoelectric figure of merit is improved by 21%.

Self‐Maintained Thermal Charging Cells for the Efficient Harvesting of Waste Heat at Elevated Temperatures

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.
Thermal charging cells (TCS) face two main challenges that limit their practical applications: 1) Still lacking the systems suitable for operation under higher temperature environments, and 2) there are limitations in the self‐sustaining performance of continuous discharge under temperature differences, which holds critical significance for the real ...

Anti/De‐Icing and Broad‐Band IR Stealth: Ag2S‐Modified Wool

EcoMat, Volume 8, Issue 5, May 2026.
This study develops the multifunctional HMWF@Ag2S wool fabric via a simple two‐step strategy: fabricating hydrophobic HMWF through DA‐HDTMS reactions, then introducing Ag2S particles onto it via a green method to form a micro‐nano structure; the optimized fabric boasts 62.3% photothermal efficiency with power generation, anti/de‐icing performances and ...

The Question of Thermoelectric Devices Electrical Resistance—A Practical Investigation From a Peltier Effect (Thermoelectric Cooler/Thermoelectric Heater) Perspective

Heat Transfer, Volume 55, Issue 3, Page 1770-1779, May 2026.
ABSTRACT Thermoelectric devices (TEDs) intrinsic electrical resistance is fundamental to its operation. This internal electrical resistance value negatively affects a TED's performance when it is operated as a thermoelectric cooler (TEC), and positively affects a TED when operated as a thermoelectric heater (TEH).

Bipolar photovoltaic effect in InSe/MoO3 van der Waals heterostructure for spontaneous light polarization detection

InfoMat, Volume 8, Issue 5, May 2026.
Bidirectional photo response in a two‐dimensional heterojunction photodetector controlled by light wavelength and polarization. Abstract Polarization is one of the most fundamental properties of light. Traditional polarization‐sensitive photodetectors, however, are limited in their ability to fully extract this information, as they translate the two ...

Triplet 4‐Nitrenemethyl‐Pyridine‐N‐Oxide: A Model Alkyl Nitrene Isolated in Cryogenic Matrices

Journal of Physical Organic Chemistry, Volume 39, Issue 5, May 2026.
The simplest triplet alkyl nitrene bearing a pyridine‐N‐oxide moiety was generated by direct irradiation (λ > 350 nm) of the corresponding azide in an Ar matrix at 15 K. Quantum tunneling 1,2‐H shift to the corresponding imine is thermodynamically favorable but does not occur due to a high‐energy barrier (~36 kcal mol−1).

Additive‐Free Edge‐Functionalized Graphene Dough

Small, Volume 22, Issue 25, 4 May 2026.
An edge‐functionalized, few‐layer graphene dough, synthesised directly from graphite, provides an additive‐free, processable graphene for moldable and printed electronic and magnetic applications. ABSTRACT The exploitation of graphene's extraordinary properties depends on finding new ways to synthesize and process it without disrupting its fundamental ...

Highly Transparent LiAl5O8 Ceramics Prepared by Spark Plasma Sintering and Its Luminescence

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT Transparent ceramics of LiAl5O8 were prepared by spark plasma sintering (SPS) using precursor powders synthesized via solid‐state reaction. The effects of sintering dwell time and cooling regime on the microstructure, transparency, and cracking of the sintered ceramics were investigated.
