The effect of three different acrylic intraocular lenses on the glistening formation [PDF]
Vojnosanitetski PregledBackground/Aim. One of the postoperative complications of phacoemulsification is the formation of fluid-filled microvacuoles inside the implanted intraocular lens (IOL). This condition is known as ‘glistening’.

The Refractometry of Lenses [PDF]
Nature, 1916 IT may be of value to opticians and others to know of a method by which the refractive indices of irregular or unpolished pieces of glass, lenses, or prisms, can be found fairly accurately—i.e. to 1 in the fourth decimal place.

Tunable Tactile Synapses Enabled by Erasable Doping in Iongel‐Gated Nanotube Network Transistors
Advanced Functional Materials, EarlyView.Artificial tactile synaptic sensors are realized by an iongel‐gated single‐walled carbon nanotube (SWCNT) transistor with reversible doping characteristics. The device senses and memorizes tactile stimuli and exhibits gate bias‐dependent excitatory or inhibitory synaptic behavior.

Designing of Self‐Dispersing Soft Dendritic Microcleaners for Microplastics Capture and Recovery
Advanced Functional Materials, EarlyView.The capture and recovery of microplastics from open aquatic systems is a complex problem, which necessitates nontrivial solutions. The principles of a comprehensive multistage process based on sustainably sourced microcleaners with hierarchical morphology are demonstrated.

Advanced Functional Materials, EarlyView.The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Advanced Functional Materials, EarlyView.Geometric multi‐bit patterning based on dynamic wetting and dewetting phenomena creates roulette‐like Physical Unclonable Function (PUF) labels with stochastic yet deterministic properties. This method leverages the solutal‐Marangoni effect for high randomness while achieving deterministic multinary patterns through polygonal confinement of binary ...
