Thermal‐Driven Diode Polarity Switching From Competing Helical Superconducting States in WTe2/α‐Fe2O3 Heterostructures

open access: yesAdvanced Materials, EarlyView.
A Nb‐proximitized Josephson junction based on a WTe2/α‐Fe2O3 heterostructure exhibits a robust superconducting diode effect with programmable polarity. The diode direction can be trained by magnetic fields and switched by temperature cycling, revealing tunable finite‐momentum pairing states and competing superconducting states in symmetry‐broken ...

n‐Type Polymer Radio Frequency Rectifiers Operating at 18.5 GHz

open access: yesAdvanced Materials, EarlyView.
Combining an n‐doped polymer semiconductor with wafer‐scale asymmetric planar electrodes featuring work function‐engineered contacts yields radio‐frequency diodes and rectifying circuits operating at up to 18.5 GHz. The devices combine scalable manufacturing with an operating frequency previously unattainable by large‐area organic electronics ...

Recombinant generation of two fragments of the rat complement inhibitory factor H[FH(SCR1-7) and FH(SCR1-4)] and their structural and functional characterization in comparison to FH isolated from rat serum [PDF]

open access: yes, 2006
Factor H (FH) is the predominant soluble inhibitor of the complement system. With a concentration of 200-800 mu g/ml in human and rat plasma it acts as a cofactor for the soluble factor I (FI)-mediated cleavage of the component C3b to iC3b.

Analysis of human factor H-related gene and protein expressed in rheumatoid arthritis synovium identifies a novel mechanism promoting dysregulated complement pathway activation

open access: yesScientific Reports
Factor H (FH) is a negative regulator of the alternative pathway (AP) of complement however, five human factor H-related (FHR) proteins, can also function ex vivo as positive regulators.

Affinity purification of human factor H on polypeptides derived from streptococcal m protein: enrichment of the Y402 variant. [PDF]

open access: yesPLoS ONE, 2013
Recent studies indicate that defective activity of complement factor H (FH) is associated with several human diseases, suggesting that pure FH may be used for therapy.

Thermodynamic Limits to Molecular Doping in Conjugated Polymers: A Perspective on Phase Behavior and Miscibility

open access: yesAdvanced Materials, EarlyView.
Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.

PspC, a Pneumococcal Surface Protein, Binds Human Factor H

open access: yes, 2001
PspC was found to bind human complement factor H (FH) by Western blot analysis of D39 ( pspC + ) and an isogenic mutant TRE108 ( pspC ).

Parity‐Dependent THz Harmonic Generation in Electrically Pumped Micro‐Lasers Exploiting Topological Insulator–Metamaterial Gratings

open access: yesAdvanced Materials, EarlyView.
Topological insulator–metamaterials integrated with electrically driven terahertz quantum cascade lasers enable parity‐dependent harmonic generation. Bulk‐dominated Bi2Se3 favors third‐harmonic emission at 9.96 THz, whereas topological‐surface‐state‐dominated Bi2Se3, Bi2Te3, and (Bi,Sb)2Te3 generate strong second harmonics near 6.5 THz.

Complement inhibitor factor H expressed by breast cancer cells differentiates CD14+ human monocytes into immunosuppressive macrophages

open access: yesOncoImmunology, 2020
Macrophages are a major immune cell type in the tumor microenvironment, where they display a tumor-supporting phenotype. Factor H (FH) is a complement inhibitor that also plays a role in several cellular functions.
