Solvent‐Free Thermal Defect Engineering in Molecular Frameworks With Volatile Linkers
Thermal removal of neutral volatile linkers enables precise and solvent‐free generation of metal vacancies in MOFs. This strategy affords redox‐stable, coordinatively unsaturated FeII sites with tunable spin, ligand coordination, and catalytic behavior. The approach offers a general route to design defect‐functional materials through local coordination

In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

Outcomes of pars plana vitrectomy in three cases of ophthalmomyiasis interna
Purpose: To report the outcomes of pars plana vitrectomy in three cases of ophthalmomyiasis interna. Observations: Case 1 is a 15-year-old male with a mobile lenticular gray-white larva in the vitreous. Case 2 is a 4-year-old female with a floating larva

Interfacial Assembly of Dye‐Doped Microparticles Driven by Combined Optical and Non‐Optical Forces
Optical trapping controls nano‐ and microparticle assembly using various forces, including absorption for photoexcitable resonant molecules. This study demonstrates photoexcitation‐mediated assembly, forming hexagonal‐close‐packed structures at the air/solution interface.

In bi‐polymeric mechanochromic cantilevers composed of polydimethylsiloxane (PDMS) and off‐stoichiometry thiol‐ene‐epoxy (OSTE+), differential swelling between the two polymers in response to VOC exposure induces a competitive bidirectional bending and corresponding color changes, with three characteristic response modes related to the Hansen ...

Management of secondary pupillary membrane in aphakia (YAG discission vs parsplana membranectomy)
Forty aphakic eyes, with secondary pupillary membranes, underwent pars plana membranectomy and YAG laser discission randomly. Visual improvement was similar in both the groups.

Three novel non‐fullerene acceptors with a DPP–pyridine‐based structure have been studied, each incorporating different π‐bridging units. LM‐Se exhibited the highest efficiency among the NFAs, and its incorporation into a ternary blend with D18 and Y6 (PCE = 17.53%) significantly enhanced performance due to improved charge dynamics and favorable film ...

Cost–benefit analysis of screening programme for diabetic retinopathy in Bulgaria
Aims Late‐diagnosed diabetic retinopathy (DR) is difficult and expensive to treat. Screening programmes can identify the disease early and reduce the costs of its future treatment. This study aims to analyse the cost–benefit of screening programmes for DR.
