Most challenges during the development of solid dosage forms are related to the impact of any variations in raw material properties, batch size, or equipment scales on the product quality and the control of the manufacturing process. With the ever pertinent restrictions on time and resource availability versus heightened expectations to develop, optimize, and troubleshoot manufacturing processes, targeted and robust science-based process modeling platforms are essential. This review focuses on the modeling of unit operations and practices involved in batch manufacturing of solid dosage forms by direct compaction. An effort is made to highlight the key advances in the past five years, and to propose potentially beneficial future study directions.

Background: Ambient ionization mass spectrometry (MS) has attracted significant attention due to its simplicity and ease of operation. Contactless, or field-induced, ionization is one of the ambient ionization techniques. In this approach, no direct electrical contact or additional voltage is required on the ionization-assisted substrate.

The integration of mid-infrared (MIR) photodetectors with built-in encryption capabilities holds immense promise for advancing secure communications in decentralized networks and compact sensing systems. However, achieving high sensitivity, self-powered operation, and reliable performance at room temperature within a miniaturized form factor remains a formidable challenge, largely due to constraints in MIR light absorption and the intricacies of embedding encryption at the device level. Here, a novel on-chip metamaterial-enhanced, 2D tantalum nickel selenide (Ta₂NiSe₅)-based photodetector, meticulously designed with a custom-engineered plasmonic resonance microstructure to achieve self-powered photodetection in the nanoampere range is unveiled.

This study presents a novel reflective fiber Fabry-Perot (F-P) salinity sensor. The sensor employs a femtosecond laser to fabricate an open liquid cavity, facilitating the unobstructed ingress and egress of the liquid, thereby enabling the direct involvement of the liquid in light transmission. Variations in the refractive index of the liquid induce corresponding changes in the effective refractive index of the optical path, which subsequently influences the output spectrum.

A compact dual-gas sensor based on the two near-infrared distributed feedback diode lasers and a multipass cell has been established for the simultaneous measurement of methane (CH) and acetylene (CH). The time division multiplexing calibration-free direct absorption spectroscopy is used to eliminate the cross interference in the application of multicomponent gas sensors. A wavelength stabilization technique based on the proportion integration differentiation feedback control is developed to suppress laser wavelength drift and an H-infinity (H) filter algorithm to reduce the system noise.

The development of safe, environmentally friendly, edible antimicrobial packaging films represents a promising alternative to conventional plastic packaging for reducing spoilage and extending the shelf life of fresh food. Here, we propose a novel strategy to construct edible β-CD-MOF/carvacrol@zein (BCCZ) composite films by intertwining β-CD-MOF loaded with the antimicrobial essential oil carvacrol, and zein. The resulting BCCZ films exhibit high humidity-triggered, long-lasting bactericidal efficacy, effective fruit preservation, and excellent biosafety.
