CsPbI₃ perovskite solar cells face stability issues due to high annealing temperatures and moisture. Butylammonium acetate (BAAc) enables stable phase formation at 160°C in ambient laboratory conditions, enhancing efficiency and stability, achieving 18.6% PCE, and maintaining over 81% efficiency after 1,000 hours of maximum power point tracking under 1

Existentially Restricted Quantified Constraint Satisfaction
The quantified constraint satisfaction problem (QCSP) is a powerful framework for modelling computational problems. The general intractability of the QCSP has motivated the pursuit of restricted cases that avoid its maximal complexity.

Single‐Step Synthesis of In‐plane 1T'‐2H Heterophase MoTe2 for Low‐Resistance Contacts
A single‐step CVD method is developed to synthesize seamless in‐plane 1T'‐2H MoTe2 heterophase junctions with precise phase control and uniform large‐area coverage. The resulting transistors, incorporating 1T' MoTe2 contacts and 2H MoTe2 channels, exhibit ultralow contact resistance, offering a scalable solution to the long‐standing challenge of ...

A previously unreported coordination motif stabilising single Fe atoms by indigo chelation and pyridyl coordination on Au(111) has been revealed. By using planar tritopic pyridyl linkers (TPyB), extended 2D porous networks of indigo3(TPyB)2Fe6 form. These networks can be crystalline or vitreous and offer an environment where individual coordination ...

A miniaturized, label‐free, and enzyme‐free biosensor (miR‐TFT) enables direct electrical detection of microRNA (miRNA) with single‐nucleotide specificity and a detection limit of 0.6 fM. Built on a tri‐channel In2O3/ZnO heterojunction and functionalized with bespoke peptide nucleic acid (PNA) probes, the device is robust, reusable, and compatible with

Epitaxial piezoelectric α‐quartz/Si BioNEMS sensors, made using soft chemistry, effectively detect the Chikungunya virus. They have a mass sensitivity of 205 pg Hz−1 in liquid and can detect the virus at a limit of 9 ng mL−1. This development enables high‐frequency mass devices for point‐of‐care testing in healthcare and other electronic applications ...

In this paper, the first use of a siloxane‐substituted silicon phthalocyanine (iso(Si3O)2SiPc) in OTFTs is reported. Moreover, this compound displays the highest hole mobility (exceeding 1 cm2 V−1 s−1) ever recorded for SiPc, and the GIWAXS study reveals thin films with an exceptionally uniform crystalline texture.
