This paper reports on a gas sensor based on two bulk acoustic wave (BAW) resonators electrically coupled with a tuneable capacitor. The weak coupling strength was tuned to its optimal value (achieving maximum sensitivity) by varying the capacitance (without complex filtering, a control circuit as required in the state of the art). A gas sensor was developed based on the electrically coupled BAW resonators by functionalizing one of the resonators with zeolitic imidazolate framework-8 (ZIF-8). It featured a quality (Q) factor of ~2.2 k in air and a resonance frequency of ~6.32 MHz. Such a simple coupling mechanism can be tuned and further extended to coupled resonators in other domains.

In this work, we present a simple, fast, and cheap procedure for the determination of mercury [Hg(II)] by square wave anodic stripping voltammetry (SWASV) at nanocomposite screen-printed graphite electrodes. The nanocomposite surfaces were obtained by the electrodeposition of poly(L-aspartic acid) on graphite screen-printed working electrodes using cyclic voltammetry (CV) and, then, of gold nanoparticles using chronoamperometry. A calibration curve by SWASV was obtained with a wide dynamic range (1–60 μg/L) and a limit of detection of 0.25 μg/L. The developed sensor was applied for the analysis of novel food samples.

Dichloromethane (DCM) is extensively used around the globe in various applications, such as in closed industrial installations for food processing or pharmaceutical extractions (vitamins, antibiotics, etc.). In the coffee sector, it is used as an extraction agent for the decaffeination process of green coffee beans. Due to its low boiling point, ranging at approx. 40 °C, DCM can be easily removed subsequent to caffeine extraction by applying state-of-the-art solvent stripping processes. The intention of this study is to assess how much DCM, if any, is present in decaffeinated coffee packages as sold to the consumer, as well as how much of the extraction solvent residue is transferred into the finally prepared, consumable coffee beverage. This study sets out to highlight DCM contents of decaf coffees, directly taken from six EU countries’ supermarket shelves. In addition, DCM mass transfer rates from roasted coffee matrices into the corresponding, variously prepared beverages (drip percolated coffee, French press) are determined. All analyses were performed applying a Headspace-GC-MS technique. All presented data demonstrate that DCM residues in the 34 coffee samples analysed have contents well below the DCM maximum residue limits for roasted coffee both in the European Union (2 mg/kg) and the USA (10 mg/kg), with an average of 0.127 mg/kg, median value of 0.059 mg/kg and P95 of 0.444 mg/kg. Furthermore, this study shows that DCM mass transfer rates from the coffee matrices into the corresponding beverages have, for drip coffee, an average of 24.7% and median of 26.8%, and for French press, an average mass transfer of 41.9% and median of 43.1%.

The loss of the sense of smell has not produced as many technological developments to mitigate the inconvenience it causes compared to the loss of vision or hearing. Anosmia or hyposmia concerns approximately 20% of the current European population and is associated with a loss of quality of life and an increased rate of household accidents. Restoring olfaction would therefore be beneficial, but it represents a technological challenge. Electrical stimulation of the nasal cavity triggers sensations that may be helpful to patients in detecting environmental odorant stimuli. We present an electrical stimulator fabricated using commercial flexible PCB technology and compare two different placement designs: A standard design based on existing medical technology that uses a metallic rod, bent to ensure contact with the nasal cavity; and a self-holding design featuring two magnets, placed across the nasal septum to ensure contact. The detection thresholds were measured for both configurations on seven normosmic individuals and show a good correlation between the two designs. Full article

Maternal nutritional status during pregnancy affects the growth of the foetus and may impair the development of different organs, some of which may affect cardio-metabolic health in early childhood. This study determined the dietary intake of pregnant women and its possible associations with early child cardio-metabolic risk. Methods: Dietary data were collected from 152 of a larger sample of 500 pregnant women and their children at birth and at the age of 5–6 years within the Tygerberg Academic Hospital catchment area, Bellville, South Africa. Maternal weight, height, BMI and mid-upper arm circumference were collected at recruitment. Birth weight, length, head circumference and placental weight were collected at birth. At the age of 5–6 years, anthropometric measurements (weight, height, skinfold thickness and waist circumference), clinical measurements (blood pressure, mean arterial pressure and heart rate) and ultrasound measurements (pancreas, aorta, carotid arteries and visceral fat) were collected. For the purpose of this abstract, we will report only on the ultrasound measurements for vascular and pancreas parameters. Dietary data were collected using a quantified food frequency questionnaire. Results: Iron intake did not differ significantly between the trimesters, nor between mothers who smoked (14.5 mg), consumed alcohol (16.5 mg) or both (15.0 mg). The average total energy intake of mothers was 10,850 kJ (SD = 3001 kJ), which was slightly above NIH recommendations. Most of the energy came in the form of saturated fat, oils and added sugar. Both protein and carbohydrate intake exceeded recommendations, with average intakes of 82 g and 275 g, respectively. Folate intake was below recommendations at 287 mcg. A significant association was found between maternal carbohydrate intake and the size of the pancreas body (0.164; p < 0.05) as well as between protein intake and aorta intima media thickness (r = 0.201; p < 0.05), while a negative association was found between polyunsaturated fat intake and left carotid intima media thickness (−0.179; p < 0.05). Conclusions: Dietary intake in this group did not indicate nutritional deficiencies. However, the low folate intake may be of concern. The association of fats with vascular wall thickness and the association of carbohydrate intake with increased pancreas size needs further investigation. Full article

Neuroaesthetics is a relatively young field that connects neuroscience with empirical aesthetics and originates in the neurological theory of aesthetic experience. It investigates brain structures and activity during the phenomena of artistic perception and production and, at the same time, attempts to understand the influence of neurological pathologies on these mechanisms. For each participant (six subjects with mild cognitive decline and ten controls), electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS) data were acquired thanks to a wearable EEG–fNIRS system during the execution of a P300 task.

Over the past few years, interest in wearable exoskeleton gloves has grown. These tools can be used to help those who are healthy or to support those who have neurological and musculoskeletal conditions like stroke, spinal cord injury, etc. The hand, which is the human body’s most flexible limb, encounters more difficult problems and recovers considerably more slowly than the lower and upper limbs. In light of these difficulties, a novel therapy called exoskeleton-based rehabilitation has gained increased significance. In this work, we concentrate on creating a wearable exoskeleton glove that is inexpensive to improve the user’s grasping abilities. The tool significantly raises the user’s gripping capacity, which raises their quality of life. The exoskeleton glove is designed to assist human hands with limited mobility during the motion rehabilitation process and to improve the grasping and dexterous manipulation capabilities of the hands of both impaired and able-bodied individuals. The proposed model consists of two types of systems, mainly the tendon driven system and the pneumatic system. The tendon-driven system is the system that helps in the flexion and extension movements of the hand. The efficiency of the exoskeleton glove is evaluated by performing the basic movements of hand like abduction, adduction, flexion, and extension. The developed hybrid exoskeleton glove can efficiently enhance the grasping capabilities of its users, offering, affordable, lightweight and easy-to-operate solutions that can assist in the execution of activities of daily living (ADL).
