Are the new particles heavy or light in $$b \rightarrow s E_{\textrm{miss}}$$ b → s E miss ?

open access: yesEuropean Physical Journal C: Particles and Fields
In this work, we study the $$B^+\rightarrow K^+ E_{\textrm{miss}}$$ B + → K + E miss , $$B^0\rightarrow K^{*0} E_{\textrm{miss}}$$ B 0 → K ∗ 0 E miss , and $$\Lambda _b^0\rightarrow \Lambda ^0 E_{\textrm{miss}}$$ Λ b 0 → Λ 0 E miss decays under three ...

Chiral Altermagnetic Magnetoelectrics

open access: yesAdvanced Materials, EarlyView.
In this work, we introduce a previously unexplored class of magnetoelectric materials, which we term chiral altermagnetic magnetoelectrics, in which structural chirality and Néel‐vector‐driven polarization are intrinsically coupled in nonpolar altermagnetic systems.

Escaping the Scaling Relationships in Oxygen Reduction Catalysis: Implications for PEM Fuel Cells

open access: yesAdvanced Materials, EarlyView.
Escaping the scaling relationships of the oxygen reduction reaction is vital for hydrogen fuel cells. This outlook examines how interfacial heterogeneity, spanning the subsurface lattice, chemisorption layer, and near‐interface solvation volume, mechanistically decouples intermediate binding energetics.

Bandgap‐Dependent Band‐to‐Band Tunneling in Carbon Nanotube Transistors

open access: yesAdvanced Materials Interfaces, EarlyView.
We systematically investigate bandgap‐dependent BTBT in SWCNT transistors by comparing wide‐bandgap (6,5) (Eg≈1.13 eV), medium‐bandgap HiPco, and narrow‐bandgap Arc‐discharge (Eg≈0.59 eV) SWCNT networks. The narrow‐bandgap networks show stronger BTBT, higher off‐state leakage, and lower on/off ratio, while wide‐bandgap (6,5) devices suppress BTBT and ...

Chiral Perturbation Theory and Nuclear Physics

open access: yes, 1997
Chiral symmetry serves as a guiding principle in low-energy hadron dynamics. An effective lagrangian, which explicitly breaks chiral symmetry via a small mass term, allows for a systematic method of calculating higher order corrections to tree-level results.

Reconnaissance Peptide Labeling Grain Boundary of Chemically Grown MoS2 Polycrystalline Monolayer

open access: yesAdvanced Materials Technologies, EarlyView.
Self‐assembled peptides on substrates, through adsorption and aggregation, offer an alternative way to label grain boundaries in chemically grown single‐layer polycrystalline MoS2. During an early nucleation step, peptides preferentially bind to grain boundaries.

Physical Chirality. It Feeds on Negative Entropy

open access: yes, 2002
Chirality is considered by many scientists to be mainly a geometric concept. There exists also a physical aspect of chirality which is largely being overlooked at. Two examples of mechanical devices are introduced here that represent ``Physical Chirality''. These are a rotating water sprinkler and a variant of Crookes' radiometer. When interacting with

Turning Water Into a Tool: From Degradation Pathways to Functional Engineering in Halide Perovskites

open access: yesAdvanced Materials Technologies, EarlyView.
Water exhibits a threshold‐dependent dual role in lead halide perovskites, acting either as a degradation trigger or as a powerful tool for defect passivation, recrystallization, and structural engineering. This review discusses how controlled water‐mediated interactions govern stability, dimensionality, and optoelectronic performance, providing ...

Printed SWCNT‐Based p–n Junction Thin‐Film Near‐Infrared Photoresistors Enabled by a Sustainable Furan‐Derived π‐Conjugated Polymer

open access: yesAdvanced Materials Technologies, EarlyView.
A sustainable polymer–carbon nanotube bilayer enables efficient near‐infrared photodetection in a simple lateral planar p–n junction thin‐film architecture. Thermal side‐chain cleavage enhances interfacial coupling, shifts the dominant photoresponse from 800 to 1000 nm, and substantially improves device performance.
